Chemists and molecular biologists have made an unexpected discovery in infection biology. The researchers can now show that two proteins that bind to one another slow down a chemical reaction central to the course of the disease in the bacteria Yersinia pseudotuberculosis. The results have been published in the Journal of Biological Chemistry.

"The discovery paves way for new insights in the regulation of bacterial virulence. The results have given us a new opportunity to study the pathogenic ability in bacteria," says Magnus Wolf-Watz, researcher at the Department of Chemistry at Ume University, who led the study together with Hans Wolf-Watz, professor at the Department of Molecular Biology.

Yersinia pseudotuberculosis and many similar bacteria infect humans by injecting toxins, so-called effector proteins, through a needle-like organelle called injectisome. Previous research has already shown that the protein YscU plays an important part in the regulation of effector protein transportation. YscU is unique in its ability to cleave itself in two parts, as a consequence, one of these parts is then transported out through the injectisome.

By combining biological experiments with studies on atomic level, the research team discovered that another protein, YscP, binds to YscU and regulates its self-cleaving abilities. When the proteins bound to one another, the speed of the self-cleaving was greatly reduced.

"The chemical process behind the self-cleaving was cooled down by the interaction and was hence slowed down. The result is a good example of how biology and chemistry nearly always go hand in hand and is a huge step forward. This gives us new opportunities to study the regulation of the course of diseases," says Hans Wolf-Watz.

The studies on atomic level were conducted using magnetic resonance spectroscopy at the Department of Chemistry at the NMR for Life platform, which is a national infrastructure for NMR in Sweden.

"The initial investment to fund an NMR instrument that the Kempe Foundations facilitated paved way for further funding from both the Wallenberg Foundations and SciLifeLab. Also, the protein expertise platform in our labs was of crucial importance for undertaking the research project," says Magnus Wolf-Watz.

STEVENS POINT - Construction of the four-story Chemistry Biology Building at the University of Wisconsin-Stevens Point has reached its tallest point.

A topping-out ceremony marks completion of the highest point in a building project. The final beam was signed by Chancellor Bernie Patterson, legislators and others Feb. 27, then placed on top of the building. More than 100 students, faculty and staff signed the UW-Stevens Point-branded beam.

The 176,500 square-foot building now dominates the campus skyline on what used to be parking lot X east of the current Science Building.

This is one symbol of all the great things going on at this campus, Patterson said.

Miron Construction Co., Inc., of Neenah is the general contractor and has up to 150 workers and subcontractors onsite each week. They are installing roofing, interior walls, piping, mechanical, electrical, plumbing and fire protection work. The exterior concrete block is completed, and brick veneer will follow, said Gerald David, Miron project superintendent.

The projects economic impact is estimated at $144 million, Patterson noted. Thats based on a formula cited by C3 Statistical Solutions to calculate construction industry impact. The project generates work for hundreds of people in construction trades, boosting jobs in other sectors that service them throughout central Wisconsin. From hotels and restaurants to hardware and office supply stores, from rental equipment to crane repair, the uptick in local business is noticeable because of the Chemistry Biology Building.

The $75.18 million project is on schedule. Work began in April 2016, and is targeted for completion in late spring 2018 for class in fall 2018.

This is the first major, free-standing academic facility built on campus since 1971. It is the largest single construction project in UW-Stevens Points 123-history, said Carl Rasmussen, facilities planning director at UW-Stevens Point. Other campus buildings have more total square footage, but were built with subsequent additions.

Given the level of complexity and size of our project, were pleased to have Miron on the job, Rasmussen said.

The Chemistry Biology Building will contain three 48-seat classrooms, two 55-seat classrooms, two 24-seat classrooms, two 96-seat lecture halls plus research and teaching labs for biology and chemistry on each floor. Flexible room configurations combined with modern technology will support hands-on learning and student research, hallmarks of a UW-Stevens Point education.

Design work is being done by Potter Lawson, Inc., Madison; and HOK, St. Louis, Mo., to meet sustainable LEED (Leadership in Energy and Environmental Design) standards.

Team chemistry critical to Doherty girls’ playoff run – Colorado Springs Gazette

Despite the fact that there are no ropes involved in basketball, holding onto one means an awful lot to the Doherty girls' basketball team.

Hold the Rope is a story, introduced last year by coach Pat McKiernan, that emphasizes team. If a teammate is hanging off the edge of a cliff, would you hold the rope? Would you hold it until your hands bled?

Doherty has utilized stellar team chemistry - created in part by Hold the Rope - to advance to the quarterfinals of the 5A state tournament. The No. 7 Spartans (24-1) face No. 2 Grandview (24-1) on Friday at the Denver Coliseum.

"We get along, we work together, and we know each other's games," said senior forward Aubriana Noti.

McKiernan thinks this edition of the Spartans - who got a first round playoff bye, and then beat No. 26 Rampart and No. 23 Fairview - is the closest-knit group he's ever had.

"The kids have really bought into this idea that we preach - we before me," he said. "There can be three, four, five, six passes to get it to the girl that's hot or to get a wide open shot. They have a lot of love for each other."

In close games, that team chemistry comes into play. Senior guard Kalani Poloa, Noti said, will look at the team and say: "This is where we hold the rope."

Doherty last advanced to the final eight in 2011-12, McKiernan's first season at the helm. One thing the 2012 team didn't have, McKiernan said, was a true post presence. This team has it in a big way courtesy of Noti, who averages over 14 points and 11 rebounds per game.

She's had 20 double-doubles in the Spartans' 25 games.

"That allows us more options on offense - we can work the ball inside, which opens up the perimeter," McKiernan said.

For Noti, it's about positioning, so she or a teammate like Poloa - who averages 14.6 points per game and reached the 1,000-point plateau this season - can score.

"Teams will double-team me," Noti said. "I expect to be able to pass it back out. I have to create space to help us score."

In February, Doherty saw several injured players return.

"It gives us more options off the bench," McKiernan said.

"It's made us into a team that's nine (players) deep, and we can give some players breaks that weren't there before."

Doherty and Grandview haven't played this season, but did face off twice in fall league.

"Both teams had all their kids. Things were still pretty raw as far as the offenses we were running, but that gave us a look at what we're up against," said McKiernan, who got his 100th win against Fairview.

The verdict? Grandview is good.

The Wolves' lone loss came against Florida's Miami Country Day, which went 29-1 and cruised to a state title.

"Without RPI, Grandview would be the No. 1 team in the state," McKiernan said. "We're going to have to play really, really well."

History of biotechnology – Wikipedia

Biotechnology is the application of scientific and engineering principles to the processing of materials by biological agents to provide goods and services.[1] From its inception, biotechnology has maintained a close relationship with society. Although now most often associated with the development of drugs, historically biotechnology has been principally associated with food, addressing such issues as malnutrition and famine. The history of biotechnology begins with zymotechnology, which commenced with a focus on brewing techniques for beer. By World War I, however, zymotechnology would expand to tackle larger industrial issues, and the potential of industrial fermentation gave rise to biotechnology. However, both the single-cell protein and gasohol projects failed to progress due to varying issues including public resistance, a changing economic scene, and shifts in political power.

Yet the formation of a new field, genetic engineering, would soon bring biotechnology to the forefront of science in society, and the intimate relationship between the scientific community, the public, and the government would ensue. These debates gained exposure in 1975 at the Asilomar Conference, where Joshua Lederberg was the most outspoken supporter for this emerging field in biotechnology. By as early as 1978, with the development of synthetic human insulin, Lederberg's claims would prove valid, and the biotechnology industry grew rapidly. Each new scientific advance became a media event designed to capture public support, and by the 1980s, biotechnology grew into a promising real industry. In 1988, only five proteins from genetically engineered cells had been approved as drugs by the United States Food and Drug Administration (FDA), but this number would skyrocket to over 125 by the end of the 1990s.

The field of genetic engineering remains a heated topic of discussion in today's society with the advent of gene therapy, stem cell research, cloning, and genetically modified food. While it seems only natural nowadays to link pharmaceutical drugs as solutions to health and societal problems, this relationship of biotechnology serving social needs began centuries ago.

Biotechnology arose from the field of zymotechnology or zymurgy, which began as a search for a better understanding of industrial fermentation, particularly beer. Beer was an important industrial, and not just social, commodity. In late 19th-century Germany, brewing contributed as much to the gross national product as steel, and taxes on alcohol proved to be significant sources of revenue to the government.[2] In the 1860s, institutes and remunerative consultancies were dedicated to the technology of brewing. The most famous was the private Carlsberg Institute, founded in 1875, which employed Emil Christian Hansen, who pioneered the pure yeast process for the reliable production of consistent beer. Less well known were private consultancies that advised the brewing industry. One of these, the Zymotechnic Institute, was established in Chicago by the German-born chemist John Ewald Siebel.

The heyday and expansion of zymotechnology came in World War I in response to industrial needs to support the war. Max Delbrck grew yeast on an immense scale during the war to meet 60 percent of Germany's animal feed needs.[2] Compounds of another fermentation product, lactic acid, made up for a lack of hydraulic fluid, glycerol. On the Allied side the Russian chemist Chaim Weizmann used starch to eliminate Britain's shortage of acetone, a key raw material for cordite, by fermenting maize to acetone.[3] The industrial potential of fermentation was outgrowing its traditional home in brewing, and "zymotechnology" soon gave way to "biotechnology."

With food shortages spreading and resources fading, some dreamed of a new industrial solution. The Hungarian Kroly Ereky coined the word "biotechnology" in Hungary during 1919 to describe a technology based on converting raw materials into a more useful product. He built a slaughterhouse for a thousand pigs and also a fattening farm with space for 50,000 pigs, raising over 100,000 pigs a year. The enterprise was enormous, becoming one of the largest and most profitable meat and fat operations in the world. In a book entitled Biotechnologie, Ereky further developed a theme that would be reiterated through the 20th century: biotechnology could provide solutions to societal crises, such as food and energy shortages. For Ereky, the term "biotechnologie" indicated the process by which raw materials could be biologically upgraded into socially useful products.[4]

This catchword spread quickly after the First World War, as "biotechnology" entered German dictionaries and was taken up abroad by business-hungry private consultancies as far away as the United States. In Chicago, for example, the coming of prohibition at the end of World War I encouraged biological industries to create opportunities for new fermentation products, in particular a market for nonalcoholic drinks. Emil Siebel, the son of the founder of the Zymotechnic Institute, broke away from his father's company to establish his own called the "Bureau of Biotechnology," which specifically offered expertise in fermented nonalcoholic drinks.[1]

The belief that the needs of an industrial society could be met by fermenting agricultural waste was an important ingredient of the "chemurgic movement."[4] Fermentation-based processes generated products of ever-growing utility. In the 1940s, penicillin was the most dramatic. While it was discovered in England, it was produced industrially in the U.S. using a deep fermentation process originally developed in Peoria, Illinois.[5] The enormous profits and the public expectations penicillin engendered caused a radical shift in the standing of the pharmaceutical industry. Doctors used the phrase "miracle drug", and the historian of its wartime use, David Adams, has suggested that to the public penicillin represented the perfect health that went together with the car and the dream house of wartime American advertising.[2] Beginning in the 1950s, fermentation technology also became advanced enough to produce steroids on industrially significant scales.[6] Of particular importance was the improved semisynthesis of cortisone which simplified the old 31 step synthesis to 11 steps.[7] This advance was estimated to reduce the cost of the drug by 70%, making the medicine inexpensive and available.[8] Today biotechnology still plays a central role in the production of these compounds and likely will for years to come.[9][10]

Even greater expectations of biotechnology were raised during the 1960s by a process that grew single-cell protein. When the so-called protein gap threatened world hunger, producing food locally by growing it from waste seemed to offer a solution. It was the possibilities of growing microorganisms on oil that captured the imagination of scientists, policy makers, and commerce.[1] Major companies such as British Petroleum (BP) staked their futures on it. In 1962, BP built a pilot plant at Cap de Lavera in Southern France to publicize its product, Toprina.[1] Initial research work at Lavera was done by Alfred Champagnat,[11] In 1963, construction started on BP's second pilot plant at Grangemouth Oil Refinery in Britain.[11]

As there was no well-accepted term to describe the new foods, in 1966 the term "single-cell protein" (SCP) was coined at MIT to provide an acceptable and exciting new title, avoiding the unpleasant connotations of microbial or bacterial.[1]

The "food from oil" idea became quite popular by the 1970s, when facilities for growing yeast fed by n-paraffins were built in a number of countries. The Soviets were particularly enthusiastic, opening large "BVK" (belkovo-vitaminny kontsentrat, i.e., "protein-vitamin concentrate") plants next to their oil refineries in Kstovo (1973) [12][13] and Kirishi (1974).[citation needed]

By the late 1970s, however, the cultural climate had completely changed, as the growth in SCP interest had taken place against a shifting economic and cultural scene (136). First, the price of oil rose catastrophically in 1974, so that its cost per barrel was five times greater than it had been two years earlier. Second, despite continuing hunger around the world, anticipated demand also began to shift from humans to animals. The program had begun with the vision of growing food for Third World people, yet the product was instead launched as an animal food for the developed world. The rapidly rising demand for animal feed made that market appear economically more attractive. The ultimate downfall of the SCP project, however, came from public resistance.[1]

This was particularly vocal in Japan, where production came closest to fruition. For all their enthusiasm for innovation and traditional interest in microbiologically produced foods, the Japanese were the first to ban the production of single-cell proteins. The Japanese ultimately were unable to separate the idea of their new "natural" foods from the far from natural connotation of oil.[1] These arguments were made against a background of suspicion of heavy industry in which anxiety over minute traces of petroleum was expressed. Thus, public resistance to an unnatural product led to the end of the SCP project as an attempt to solve world hunger.

Also, in 1989 in the USSR, the public environmental concerns made the government decide to close down (or convert to different technologies) all 8 paraffin-fed-yeast plants that the Soviet Ministry of Microbiological Industry had by that time.[citation needed]

In the late 1970s, biotechnology offered another possible solution to a societal crisis. The escalation in the price of oil in 1974 increased the cost of the Western world's energy tenfold.[1] In response, the U.S. government promoted the production of gasohol, gasoline with 10 percent alcohol added, as an answer to the energy crisis.[2] In 1979, when the Soviet Union sent troops to Afghanistan, the Carter administration cut off its supplies to agricultural produce in retaliation, creating a surplus of agriculture in the U.S. As a result, fermenting the agricultural surpluses to synthesize fuel seemed to be an economical solution to the shortage of oil threatened by the Iran-Iraq war. Before the new direction could be taken, however, the political wind changed again: the Reagan administration came to power in January 1981 and, with the declining oil prices of the 1980s, ended support for the gasohol industry before it was born.[1]

Biotechnology seemed to be the solution for major social problems, including world hunger and energy crises. In the 1960s, radical measures would be needed to meet world starvation, and biotechnology seemed to provide an answer. However, the solutions proved to be too expensive and socially unacceptable, and solving world hunger through SCP food was dismissed. In the 1970s, the food crisis was succeeded by the energy crisis, and here too, biotechnology seemed to provide an answer. But once again, costs proved prohibitive as oil prices slumped in the 1980s. Thus, in practice, the implications of biotechnology were not fully realized in these situations. But this would soon change with the rise of genetic engineering.

The origins of biotechnology culminated with the birth of genetic engineering. There were two key events that have come to be seen as scientific breakthroughs beginning the era that would unite genetics with biotechnology. One was the 1953 discovery of the structure of DNA, by Watson and Crick, and the other was the 1973 discovery by Cohen and Boyer of a recombinant DNA technique by which a section of DNA was cut from the plasmid of an E. coli bacterium and transferred into the DNA of another.[14] This approach could, in principle, enable bacteria to adopt the genes and produce proteins of other organisms, including humans. Popularly referred to as "genetic engineering," it came to be defined as the basis of new biotechnology.

Genetic engineering proved to be a topic that thrust biotechnology into the public scene, and the interaction between scientists, politicians, and the public defined the work that was accomplished in this area. Technical developments during this time were revolutionary and at times frightening. In December 1967, the first heart transplant by Christian Barnard reminded the public that the physical identity of a person was becoming increasingly problematic. While poetic imagination had always seen the heart at the center of the soul, now there was the prospect of individuals being defined by other people's hearts.[1] During the same month, Arthur Kornberg announced that he had managed to biochemically replicate a viral gene. "Life had been synthesized," said the head of the National Institutes of Health.[1] Genetic engineering was now on the scientific agenda, as it was becoming possible to identify genetic characteristics with diseases such as beta thalassemia and sickle-cell anemia.

Responses to scientific achievements were colored by cultural skepticism. Scientists and their expertise were looked upon with suspicion. In 1968, an immensely popular work, The Biological Time Bomb, was written by the British journalist Gordon Rattray Taylor. The author's preface saw Kornberg's discovery of replicating a viral gene as a route to lethal doomsday bugs. The publisher's blurb for the book warned that within ten years, "You may marry a semi-artificial man or womanchoose your children's sextune out painchange your memoriesand live to be 150 if the scientific revolution doesnt destroy us first."[1] The book ended with a chapter called "The Future If Any." While it is rare for current science to be represented in the movies, in this period of "Star Trek", science fiction and science fact seemed to be converging. "Cloning" became a popular word in the media. Woody Allen satirized the cloning of a person from a nose in his 1973 movie Sleeper, and cloning Adolf Hitler from surviving cells was the theme of the 1976 novel by Ira Levin, The Boys from Brazil.[1]

In response to these public concerns, scientists, industry, and governments increasingly linked the power of recombinant DNA to the immensely practical functions that biotechnology promised. One of the key scientific figures that attempted to highlight the promising aspects of genetic engineering was Joshua Lederberg, a Stanford professor and Nobel laureate. While in the 1960s "genetic engineering" described eugenics and work involving the manipulation of the human genome, Lederberg stressed research that would involve microbes instead.[1] Lederberg emphasized the importance of focusing on curing living people. Lederberg's 1963 paper, "Biological Future of Man" suggested that, while molecular biology might one day make it possible to change the human genotype, "what we have overlooked is euphenics, the engineering of human development."[1] Lederberg constructed the word "euphenics" to emphasize changing the phenotype after conception rather than the genotype which would affect future generations.

With the discovery of recombinant DNA by Cohen and Boyer in 1973, the idea that genetic engineering would have major human and societal consequences was born. In July 1974, a group of eminent molecular biologists headed by Paul Berg wrote to Science suggesting that the consequences of this work were so potentially destructive that there should be a pause until its implications had been thought through.[1] This suggestion was explored at a meeting in February 1975 at California's Monterey Peninsula, forever immortalized by the location, Asilomar. Its historic outcome was an unprecedented call for a halt in research until it could be regulated in such a way that the public need not be anxious, and it led to a 16-month moratorium until National Institutes of Health (NIH) guidelines were established.

Joshua Lederberg was the leading exception in emphasizing, as he had for years, the potential benefits. At Asilomar, in an atmosphere favoring control and regulation, he circulated a paper countering the pessimism and fears of misuses with the benefits conferred by successful use. He described "an early chance for a technology of untold importance for diagnostic and therapeutic medicine: the ready production of an unlimited variety of human proteins. Analogous applications may be foreseen in fermentation process for cheaply manufacturing essential nutrients, and in the improvement of microbes for the production of antibiotics and of special industrial chemicals."[1] In June 1976, the 16-month moratorium on research expired with the Director's Advisory Committee (DAC) publication of the NIH guidelines of good practice. They defined the risks of certain kinds of experiments and the appropriate physical conditions for their pursuit, as well as a list of things too dangerous to perform at all. Moreover, modified organisms were not to be tested outside the confines of a laboratory or allowed into the environment.[14]

Atypical as Lederberg was at Asilomar, his optimistic vision of genetic engineering would soon lead to the development of the biotechnology industry. Over the next two years, as public concern over the dangers of recombinant DNA research grew, so too did interest in its technical and practical applications. Curing genetic diseases remained in the realms of science fiction, but it appeared that producing human simple proteins could be good business. Insulin, one of the smaller, best characterized and understood proteins, had been used in treating type 1 diabetes for a half century. It had been extracted from animals in a chemically slightly different form from the human product. Yet, if one could produce synthetic human insulin, one could meet an existing demand with a product whose approval would be relatively easy to obtain from regulators. In the period 1975 to 1977, synthetic "human" insulin represented the aspirations for new products that could be made with the new biotechnology. Microbial production of synthetic human insulin was finally announced in September 1978 and was produced by a startup company, Genentech.[15] Although that company did not commercialize the product themselves, instead, it licensed the production method to Eli Lilly and Company. 1978 also saw the first application for a patent on a gene, the gene which produces human growth hormone, by the University of California, thus introducing the legal principle that genes could be patented. Since that filing, almost 20% of the more than 20,000 genes in the human DNA have been patented.[citation needed]

The radical shift in the connotation of "genetic engineering" from an emphasis on the inherited characteristics of people to the commercial production of proteins and therapeutic drugs was nurtured by Joshua Lederberg. His broad concerns since the 1960s had been stimulated by enthusiasm for science and its potential medical benefits. Countering calls for strict regulation, he expressed a vision of potential utility. Against a belief that new techniques would entail unmentionable and uncontrollable consequences for humanity and the environment, a growing consensus on the economic value of recombinant DNA emerged.[citation needed]

With ancestral roots in industrial microbiology that date back centuries, the new biotechnology industry grew rapidly beginning in the mid-1970s. Each new scientific advance became a media event designed to capture investment confidence and public support.[15] Although market expectations and social benefits of new products were frequently overstated, many people were prepared to see genetic engineering as the next great advance in technological progress. By the 1980s, biotechnology characterized a nascent real industry, providing titles for emerging trade organizations such as the Biotechnology Industry Organization (BIO).

The main focus of attention after insulin were the potential profit makers in the pharmaceutical industry: human growth hormone and what promised to be a miraculous cure for viral diseases, interferon. Cancer was a central target in the 1970s because increasingly the disease was linked to viruses.[14] By 1980, a new company, Biogen, had produced interferon through recombinant DNA. The emergence of interferon and the possibility of curing cancer raised money in the community for research and increased the enthusiasm of an otherwise uncertain and tentative society. Moreover, to the 1970s plight of cancer was added AIDS in the 1980s, offering an enormous potential market for a successful therapy, and more immediately, a market for diagnostic tests based on monoclonal antibodies.[16] By 1988, only five proteins from genetically engineered cells had been approved as drugs by the United States Food and Drug Administration (FDA): synthetic insulin, human growth hormone, hepatitis B vaccine, alpha-interferon, and tissue plasminogen activator (TPa), for lysis of blood clots. By the end of the 1990s, however, 125 more genetically engineered drugs would be approved.[16]

Genetic engineering also reached the agricultural front as well. There was tremendous progress since the market introduction of the genetically engineered Flavr Savr tomato in 1994.[16] Ernst and Young reported that in 1998, 30% of the U.S. soybean crop was expected to be from genetically engineered seeds. In 1998, about 30% of the US cotton and corn crops were also expected to be products of genetic engineering.[16]

Genetic engineering in biotechnology stimulated hopes for both therapeutic proteins, drugs and biological organisms themselves, such as seeds, pesticides, engineered yeasts, and modified human cells for treating genetic diseases. From the perspective of its commercial promoters, scientific breakthroughs, industrial commitment, and official support were finally coming together, and biotechnology became a normal part of business. No longer were the proponents for the economic and technological significance of biotechnology the iconoclasts.[1] Their message had finally become accepted and incorporated into the policies of governments and industry.

According to Burrill and Company, an industry investment bank, over $350 billion has been invested in biotech since the emergence of the industry, and global revenues rose from $23 billion in 2000 to more than $50 billion in 2005. The greatest growth has been in Latin America but all regions of the world have shown strong growth trends. By 2007 and into 2008, though, a downturn in the fortunes of biotech emerged, at least in the United Kingdom, as the result of declining investment in the face of failure of biotech pipelines to deliver and a consequent downturn in return on investment.[17]

iShares NASDAQ Biotechnology Index (ETF)(NASDAQ:IBB … – ETF Daily News (blog)

March 3, 2017 6:13am NASDAQ:IBB

From Taki Tsaklanos: Biotechnology stocks are breaking out. They have been consolidating for nearly 20 months. Investors lost interestand that is exactly what smart investors, in general, want to see in order to buy a market.

That is also how bull markets start: when nobody talks about it and only a minority of investors is buying it.

Now here it becomes interesting. InvestingHavens research team has closely followed biotechnology, and has written extensively about it last year. The red line throughout all articles was that smart investors are not in a hurry to buy biotech, but prefer to see which direction biotech would go. This is what was published on InvestingHaven until fall of last year:

Biotechnology Close To A Major Breakdown Level

Health Sector Testing All-Time Highs In 2016, Biotech A Buy After Breaking Out

Alert: Biotechnology and Health Sector Testing Long Time Support

Biotechnology Stocks Have News For Investors: It is Now or Never

In other words, on several occasions last year biotechnology stocks were ready to break down, but eventually they did not. The market refused to go lower, and that was a very important observation, which was shared with our readers: Biotechnology Stocks Refusing To Break Down

Then, something very interesting happened in January: Biotech And Health Care Stock Market Sector Showing Signs Of Life. That was the first sign that biotechnology stocks could go higher.

Today, they are attempting to break out.

The most interesting part was what InvestingHavens team wrote last year in April: Biotechnology Sentiment At Multi-Year Extremes. What Should Investors Do? Right at a time when a major breakout attempt in biotechnology stocks was at play, at a time when sentiment was extremely bullish, we wrote this:

What does all this mean to investors? Combining chart patterns with sentiment data is very useful for investors. We believe that a short term top has developed. Biotechnology needs to cool off a bit, which means a retracement is the most likely outcome for the coming weeks. The key is to watch how far the retracement will go: if prices remain within the existing pattern, above support, there is an opportunity for investors to buy the dips. As long as prices remain within the current chart pattern, it is not a good idea to short this market, unless you are a very short term oriented trader.

As a reminder, it was when IBB was trading at 280 points, in April last year, right before it fell 15 percent. Astute readers were very happy, and they keep on thanking us for our wise words.

Right now, biotechnology stocks are going through a serious attempt to break out from their 20-month consolidation period. If the 300 level in IBB holds for at least 5 consecutive days, biotech will go higher in the coming weeks and months.

The iShares NASDAQ Biotechnology Index ETF (NASDAQ:IBB) was unchanged in premarket trading Friday. Year-to-date, IBB has gained 12.97%, versus a 6.59% rise in the benchmark S&P 500 index during the same period.

IBB currently has an ETF Daily News SMART Grade of A (Strong Buy), and is ranked #2 of 36 ETFs in the Health & Biotech ETFs category.

Biochemical ‘fossil’ shows how life may have emerged without … – Science Daily

One major mystery about life's origin is how phosphate became an essential building block of genetic and metabolic machinery in cells, given its poor accessibility on early Earth. In a study published on March 9 in the journal Cell, researchers used systems biology approaches to tackle this long-standing conundrum, providing compelling, data-driven evidence that primitive life forms may not have relied on phosphate at all. Instead, a few simple, abundant molecules could have supported the emergence of a sulfur-based, phosphate-free metabolism, which expanded to form a rich network of biochemical reactions capable of supporting the synthesis of a broad category of key biomolecules.

"The significance of this work is that future efforts to understand life's origin should take into account the concrete possibility that phosphate-based processes, which are essential today, may not have been around when the first life-like processes started emerging," says senior study author Daniel Segr (@dsegre) of Boston University. "An early phosphate-independent metabolism capable of producing several key building blocks of living systems is in principle viable."

Phosphate is essential for all living systems and is present in a large proportion of known biomolecules. A sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. Moreover, phosphate is a critical component of adenosine triphosphate (ATP), which transports chemical energy within cells, and a compound called NADH, which has several essential roles in metabolism. But it is unclear how phosphate could have assumed these central roles on primordial Earth, given its scarcity and poor accessibility.

In light of this puzzle, some have proposed that early metabolic pathways did not rely on phosphate. In many of these scenarios, sulfur and iron found on mineral surfaces are thought to have fulfilled major catalytic and energetic functions prior to the appearance of phosphate. One notable origin-of-life scenario suggests that the role of ATP was originally assumed by sulfur-containing compounds called thioesters, which are widely involved in protein, carbohydrate, and lipid metabolism. Despite the availability of iron and sulfur on early Earth, concrete evidence supporting these scenarios has been lacking.

To test the feasibility of the "iron-sulfur world hypothesis" and the "thioester world scenario," Segr and his team used computational systems biology approaches originally developed for large-scale analyses of complex metabolic networks. The researchers used a large database to assemble the complete set of all known biochemical reactions. After exploring this so-called "biosphere-level metabolism," the researchers identified a set of eight phosphate-free compounds thought to have been available in prebiotic environments. They then used an algorithm that simulated the emergence of primitive metabolic networks by compiling all possible reactions that could have taken place in the presence of these eight compounds, which included formate, acetate, hydrogen sulfide, ammonium, carbon dioxide, water, bicarbonate, and nitrogen gas.

This analysis revealed that a few simple prebiotic compounds could support the emergence of a rich, phosphate-independent metabolic network. This core network, consisting of 315 reactions and 260 metabolites, was capable of supporting the biosynthesis of a broad category of key biomolecules such as amino acids and carboxylic acids. Notably, the network was enriched for enzymes containing iron-sulfur clusters, bolstering the idea that modern biochemistry emerged from mineral geochemistry. Moreover, thioesters rather than phosphate could have enabled this core metabolism to overcome energetic bottlenecks and expand under physiologically realistic conditions.

"Before our study, other researchers had proposed a sulfur-based early biochemistry, with hints that phosphate may not have been necessary until later," Segr says. "What was missing until now was data-driven evidence that these early processes, rather than scattered reactions, could have constituted a highly connected and relatively rich primitive metabolic network."

Although this non-experimental evidence does not definitively prove that life started without phosphate, it provides compelling support for the iron-sulfur world hypothesis and the thioester world scenario. At the same time, the study calls into question the "RNA world hypothesis," which proposes that self-replicating RNA molecules were the precursors to all current life on Earth. Instead, the results support the "metabolism-first hypothesis," which posits that a self-sustaining phosphate-free metabolic network predated the emergence of nucleic acids. In other words, nucleic acids could have been an outcome of early evolutionary processes rather than a prerequisite for them.

"Evidence that an early metabolism could have functioned without phosphate indicates that phosphate may have not been an essential ingredient for the onset of cellular life," says first author Joshua Goldford of Boston University. "This proto-metabolic system would have required an energy source and may have emerged either on the Earth's surface, with solar energy as the main driving force, or in the depth of the oceans near hydrothermal vents, where geochemical gradients could have driven the first life-like processes."

In future studies, the researchers will continue to apply systems biology approaches to study the origin of life. "My hope is that these findings will motivate further studies of the landscape of possible historical paths of metabolism, as well as specific experiments for testing the feasibility of a phosphate-free sulfur-based core biochemistry," Segr says. "The idea of analyzing metabolism as an ecosystem-level or even planetary phenomenon, rather than an organism-specific one, may also have implications for our understanding of microbial communities. Furthermore, it will be interesting to revisit the question of how inheritance and evolution could have worked prior to the appearance of biopolymers."

Kevin Owens: The Anatomy Of A WWE Promo – Cultured Vultures

Kevin Owens is awesome. Whether you first met him as Kevin Steen, or whether he pop-up power bombed his way into your consciousness as Kevin Owens, its no secret that the man is one of WWEs hottest players right now. And when he turned on his best friend Chris Jericho in Las Vegas, his hot streak only intensified. His show-opening promo the following week did not disappoint, in part because of the story being told but also because of the techniques he was using in order to make his promo that much more impactful.

First, the ring staging. KO sat on a steel chair in the very centre of the ring, a microphone in his right hand and his left hand curled around the rim of his championship belt. A single spotlight lit him in the ring. None of these were particularly subtle techniques, but the point was hammered home even before the man opened his mouth pay attention everyone, because at this moment in time, Kevin Owens is comfortable. Kevin Owens is the champion and Kevin Owns is the centre of the universe. This gave him the platform upon which to build a solid promo, a task he would have found much harder had the lights been up or the chair been missing.

His delivery was excellent, for a number of reasons. First, the majority of his promo was either delivered with his head bowed down and his eyes to the floor, or looking straight down the camera. Both of these positions disregarded the live audience, which sent the signal that what KO had to say transcended this crowd. There were no cheap, location-specific lines here for easy heat this promo felt important because it felt non-specific to one arena, and therefore more relevant to the entire WWE Universe.

Owens varied up both his pace, his volume and his intonation. Its speech-giving 101, but a point overlooked by a surprising number of WWE performers. Because of this, his promo followed the patterns of normal speech, and hence felt both natural and sincere and the audience loves nothing more than a man who believes his own hype. Imagine the impact the promo would have had (or lack thereof) had it all been delivered in a dull, steady monotone.

Note how KO acknowledged the crowd throughout. Not with his whole body, but just his head. This feeds in to a wider point about his promo, and thats how still he was throughout. By cutting down on the amount of physical movement in the segment, all the audience had to focus on were his words. And when he did choose to make a physical motion, such as standing up, it felt like a calculated movement which served a purpose instead of a random choice, all of which heightened the impression that here was a man in full control, a man with power and a man we should take interest in.

And he showed us exactly how to avoid the What chants so symptomatic of a typical WWE live crowd these days. By starting the first word of his next sentence in the same breath as his last, he often avoided the natural rhythm of sentence-WHAT-sentence-WHAT-sentence-WHAT that the WWE crowd so loves. His delivery of In fact, I never believed the hype. Even Even when I was. exemplified this small yet effective tool. Most fans will agree that a What chant during a promo has the potential to ruin its impact, and so by countering this with his delivery Owens made sure that his promo mattered.

He also peppered his promo with small, barely noticeable shakes of his head. It was the sort of confident gesture which implied that the audience just didnt get it, that he had a perspective the audience lacked, that he was in some way one step ahead of everyone else. By doing so he added another layer to his performance, which helped him more easily exude an air of confidence, power and control that ultimately held the audiences attention for the whole promo.

Will Kevin Owens drop the Universal title to Goldberg at Fastlane? Probably. Will he find a way to remain over with the crowd even without the gold? With in-ring work like his, sure. With promo skills like his, absolutely.

Twentysomething who's well aware he knows nothing about anything.

Artificial embryo shows early potential for medical therapies, not babies – Gant Daily

Trying to mimic the early stages of reproduction, Cambridge University researchers cultivated two types of mouse stem cells in a Petri dish and watched an embryo emerge one that closely resembled a natural mouse embryo in its architecture, its development process and its ability to assemble itself.

The artificial structure shows promise as a tool for medical research, though it cannot develop into an actual baby.

I not only want to understand the basic biology of development but also why it goes awry in the early stages of up to 70% of human pregnancies, said Magdalena Zernicka-Goetz, senior author of the research, which was published Thursday in the journal Science.

Natures way

After an egg is fertilized by a sperm, it begins to divide multiple times. This process generates a small, free-floating ball of stem cells: a blastocyst.

Within a mammalian blastocyst, the cells that will become the body of the embryo (embryonic stem cells) begin to cluster at one end. Two other types of cells, the extra-embryonic trophoblast stem cells and the endoderm stem cells, begin to form patterns that will eventually become a placenta and a yolk sac, respectively.

To develop further, the blastocyst has to implant in the womb, where it transforms into a more complex architecture. However, implantation hides the embryo from view and from experimentation.

In the study, Zernicka-Goetz wanted to replicate developing embryonic events using stem cells.

Other scientists who have attempted the same thing have used only embryonic stem cells, but these experiments, though they have yielded embryoid bodies, have not been entirely successful. The artificial bodies never follow the same chain of events found in nature, and they lack the structure of a natural embryo.

Zernicka-Goetz, a professor in Cambridges Department of Physiology, Development and Neuroscience, hypothesized that the trophoblast stem cells communicate with the embryonic stem cells and guide their development.

She and her colleagues placed embryonic and trophoblast stem cells within an extra-cellular matrix: the non-cell component found in all tissues and organs that provides biochemical support to cells. This formed a scaffold on which the two stem cell types could co-develop.

The embryonic stem cells sent chemical messages to the trophoblast stem cells and vice versa, said Zernicka-Goetz. Essentially, the different stem cells began to talk to each other, and this helped the embryonic stem cells, she explained.

They respond by turning on particular developmental gene circuits or by physically changing shape to accomplish some architectural remodeling, she wrote in an email. This happens in normal embryogenesis and it is what we are trying to recreate in the culture dish.

Ultimately, the cells organized themselves into a structure that not only looked like an embryo, it behaved like one, with anatomically correct regions developing at the right time and in the right place.

The results were spectacular they formed structures that developed in a way strongly resembling embryos in their architecture and expressing specific genes in the right place and at the right time, Zernicka-Goetz wrote.

Despite its resemblance to a real embryo, this artificial embryo will not develop into a healthy fetus, the researchers said. That would require the endoderm stem cells, which does other things that are most likely necessary for further development, said Zernicka-Goetz.

Whether adding these to the system would be enough to achieve further development, I dont know, she said.

Correct placental development is essential for proper implantation into either the womb or a substitute for the womb, she said. To achieve this will be some time off.

Therapeutic applications

Robin Lovell-Badge, an embryologist and head of the Division of Stem Cell Biology and Developmental Genetics at the Francis Crick Institute, found the new research to be interesting on a number of counts.

He wrote in a commentary published with the study on the website of the journal Science that past research suggests that the cells fated to become support structures (placenta and yolk sac) for the embryo in fact organize the cell types within the embryo. Meanwhile, the new research suggests that it is the combination of the two cell types (embryonic and trophectoderm) that is important while the third cell type, endoderm, may not be essential.

According to Dr. Christos Coutifaris, president-elect of the American Society for Reproductive Medicine and a professor at the University of Pennsylvania, the new study is significant because it shows how the cells that are extra-embryonic the ones that are going to give rise to the placenta actually play a role in the development of cells that eventually become the fetus.

Its not two completely separate entities, Coutifaris said, referring to the embryo and its support structure. Understanding how the two types of cells interact and the chemical signals they exchange is really, really critical.

Zernicka-Goetzs model has practical applications in research, where it can be used to better understand the conversation between embryonic stem cells and trophoblast stem cells, he said. You can manipulate these cells molecularly to try to understand these interactions and how early development occurs pre-implantation.

According to Kyle E. Orwig, an associate professor of obstetrics, gynecology and reproductive sciences, and molecular genetics and biochemistry at the University of Pittsburgh, Zernicka-Goetzs model will enable investigators to investigate the effects of genetic manipulations, environmental toxins, therapeutics and factors on embryo development. Artificial embryos represent a powerful tool for research that might reduce (but not eliminate) the need for human embryos, Orwig said.

Dr. David Adamson, a reproductive endocrinologist, an adjunct clinical professor at Stanford University and chairman of the International Committee Monitoring Assisted Reproductive Technologies, believes that its very important to continue to do basic science research in reproductive medicine.

How our species reproduces is very important to know, Adamson said. When you learn about reproduction and learn how cells reproduce and how cells differentiate and what makes things happen normally and what makes thing happen abnormally, then there clearly are a lot of potential therapeutic applications.

Past advances in reproductive medicine have helped scientists prevent genetic-based diseases, he said. Specifically, in vitro fertilization techniques have allowed doctors to biopsy and conduct genetic tests on embryos to prevent inherited illnesses, including Huntingtons.

In vitro fertilization is fundamentally transformative, said Adamson, who sees the new research as adding to the wealth of knowledge about this procedure.

In fact, Zernicka-Goetz works in the same nondescript brick building on the Cambridge campus where Robert Edwards, a reproductive medicine pioneer, once toiled. Edwards developed the Nobel Prize-winning technique of in vitro fertilization, which eventually resulted in the birth of the first test tube baby, Louise Brown.

Helping families have babies is the most obvious contribution of in vitro fertilization. Today, Adamson said, there have been approximately 6.5 million babies born using in vitro fertilization since the procedure was first developed. An exact number is not known because many countries, including China, do not have registries to count them, explained Adamson.

Meanwhile, Zernicka-Goetz said she will continue her work on embryonic development as she and the members of her lab are totally driven by a curiosity to understand these fundamental aspects of life.

She plans to use human stem cells to create a similar embryonic model. Then she plans to use that model to learn more about normal embryonic development and understand when it goes wrong without needing to experiment on an actual human embryo.

The work also continually teaches us about the properties of stem cells, Zernicka-Goetz said. She added that this knowledge is useful for developing therapies to replace faulty tissues in so-called regenerative medicine.

The Legend of Zelda: Breath of the Wild makes chemistry just as important as physics – VentureBeat

Youve probably heard of physics engines in games. But what about chemistry engines?

The Legend of Zelda: Breath of the Wilds technical director, Takuhiro Dohta, talked about some of the open-world games design philosophies at the Game Developers Conference in San Francisco. The anticipated title launches soon (it might even be out by the time youre reading this). Itll be available as a launch title for the Switch on March 3, and its coming out for the Wii U that same day. We gave it a score of 100/100 in our review

Dohta said thatNintendo decided that its new Zelda needed a chemistry engine. If physics engines dictate how objects influence the way things move, a chemistry engine could be in charge of how objects change each others states.

Basically, Breath of the Wilds physics engine has three rules:

So, fire (an element) can set a tree (a material) on fire. But a tree cant change the state of another tree. However, water (another element) can put out a fire.

Above: Its all connected.

Image Credit: GamesBeat

But Zelda lets playersget more creative than that. This interaction of elements and objects is one of the keys that makes Breath of the Wild such an interesting game. It lets players experiment and find unique solutions to problems. For example, you could fan a giant leaf at a sail on a boat to move it, or you could throw a sword toward a group of enemies during a storm to attract a lightning bolt in their area.

Dohta admitted that this kind of chemistry isnt real chemistry. Little of it would scientifically work in the real world. However, a sense of in-game logic dictates theway everything interacts. In real life, a leaf, no matter how big, couldnt make enough wind to move a sailboat. But in the game, it makes sense once you become familiar with theitems mechanics.

Nintendo wants people to feel like geniuses when they play Breath of the Wild, and this chemistry engine makes those ah ha moments possible.

When Celebrity And Science Collide: Hollywood And The Anti … – Genetic Literacy Project

Julie Kelly, cooking instructor, food writer, blogger and a Mom who lives in the Chicago area. In 2015, she got passionate about GMOs. Kelly is a contributing writer to the Wall Street Journal, National Review, Huffington Post, The Hill and other media outlets.| March 2, 2017

HIGHLIGHTS:

Hollywood is in our homes daily,often spreading misconceptions about science, and GE crops in particular Gary Hirshberg, founder of Stonyfield Organic and Just Label It, is the key celebrity organizer Gwyneth Paltrow has emerged as the face of celebrity moms who question the safety of GE foods Mark Ruffalo questions GE foods but also rejects biotechnological solutions beyond food, such as the gene-edited mosquito that could curtail the Zika virus Celebrity misinformation campaigns have filled a void created by the agricultural and food industries, which have been reticent to defend the science of biotechnology While the Internet and social media are valuable tools for disseminating information about complicated subjects like science and agriculture, it has also given rise to a modern-day monster: the expert celebrity From movie stars to television chefs, a cadre of self-promoting yet often ill-informed celebrities are influencing the public discussion about topics way beyond their expertise, particularly consequential issueslike vaccines and biotechnology

The explosive growth of cable television and more recently of the Internet has led to a celebrication of everyday lifeHollywood has invaded our homes in an oddly intimate way. Celebrities have long weighed in on public issues, which is okay if the issue is what clothes to wear next season, but science is different: it actually can impact peoples lives.

If Big Bang star Mayim Bialik talks about Zikas impact on the brain, we might be interested because she has a PhD in neurosurgeryshe has genuine credentials. But science-educated stars are few and far between. For example, campaigns led by Robert Kennedy, Jr., reality TV star Jenny McCarthy and her former husband Jim Carrey and flip comments by Bill Maher have convinced a lot of credulous fans to forgo getting their kids vaccinated the lowest vaccination rates in the country are in the swanky Hollywood suburban playgrounds. And thats just one of many misguided celebrity-driven campaigns.

Celebrities may have any number of motives for injecting themselves into the middle of debates over controversial, scientific issues. Ego, for example. Its a way to get publicity for themselves (McCarthy is more known now for her anti-vaccine activism than for her acting.) And as we know, stars are eager to follow the cause du jour. It is science-as-fashion.

While some people wisely ignore celebrity advice, their ill-informed and selectively ignorant comments can sway public opinion in destructive ways. Thats whats happening in the ongoing debate over our food and farming systems. In the last few years, movies such as Consumed and GMO OMG have fueled misperceptions about genetic engineering. And celebrity chefs such as Tom Colicchio have joined the fray, partnering with other anti-GMO chefs in a Facebook page, Chefs Against GMOs, and making appeals in Washington and on TV shows. But Hollywood is where anti-GMO groups draw their most visible campaigners.

A slew of Hollywood celebrities, have lent their names to one anti-GMO or pro-labeling campaign or another, among them a fading generation of actors and musicians: Morgan Freeman, Paul McCartney, Dave Mathews, Danny DeVito, Woody Harrelson and Neil Young, to name just a few. But there are some younger faces who have lobbied hard against modern agriculture, mostly B-list actresses, with Gwyneth Paltrow the most prominent. They rail against GMOs in an effort to persuade consumers our food system is hopelessly broken, and that crop biotechnology is scary, unnatural and part of a corporate conspiracy to control the worlds food supply. Its easily dismissible nonsense to those who know the consensus science, but their distortions have consequences outside of clickbait headlines.

Paltrow has emerged as the face of the anti-GMO movement over the last few years. Its unclear exactly how or why she decided to take up this cause except that she has worked closely with one of the most powerful figures in the organic movement, Gary Hirshberg, founder of Stonyfield Organic, who also started Just Label It, which has campaigned for mandatory labels. Just Label it and the organic industry in general have spent hundreds of millions of dollars in recent years to demonize conventional agriculture and mislead consumers into thinking organic food is healthier, safer and more nutritious than conventional food.

Although state-of-the-art meta studies conclude there are no meaningful differences, and some research shows organic farming is more stressful on the environment than farming using advanced technology including genetically engineered crops, organic companies peddle that narrative in hopes of driving consumers toward their pricier products. As the self-appointed priestess of all that is healthy and good in the world, Paltrow promotes organic food, which is by definition non-GMO.

Hirshberg has fueled and funded anti-GMO advocacy under the guise of promoting mandatory GMO labels. He has organized several anti-GMO groups, and has used celebrities like Paltrow to push his agenda. At his invitation, Paltrow was featured at a press conference on Capitol Hill in August 2015 to voice her support for mandatory GMO labeling. A bill the organic industry opposed had just passed in the House, and Paltrow wanted to use her powers of persuasion to stop the bill from advancing in the Senate:

Im not here as an expert, Im here as a mom who honestly believes I have the right to know whats in the food I feed my family. And we dont even know, the science is still inconclusive about GMOs, there are arguments they could possibly be harmful and there are arguments that they could be incredibly beneficial. But at this point, we just dont know.

The presser echoed widely on social media, but most disturbingly, her comments were reported uncritically by major media sites, giving her credibility on an issue she did not deserve.

Here is where Paltrow is wrong. We do know that GMOs are safe. They hold tremendous potential and promise to alleviate global hunger now and into the future as food demands are expected to nearly double by 2050.Nearly every major independent scientific organization and governmental agency in the world, including most recently the National Academies of Sciences, Engineering and Medicine (NAS), have affirmed that genetically engineered crops and food are just as healthy and environmentally safe as other conventionally grown foods, including organic. American farmers have been using genetically modified seeds for 20 years and most of the corn, soy, cotton and sugarbeets grown are from those seeds. This has cut down on the use of pesticides (since some of those crops have been developed to include natural pesticides already used by organic farmers), which has reduced crop losses and increased yield, a huge boon to both farmers and consumers.

In its analysis of the GMO controversy, the NAS also noted several problems with mandatory labeling, such as higher costs to consumers and the probability that companies might eliminate genetically engineered ingredients in order to avoid labels. The report also outlined several crops that can only be achieved through genetic engineering that boost nutrients, withstand climate challenges and resist crop diseases. Promising new crops in the pipeline include nutritionally enhanced rice and bananas and disease-resistant cassava, a plant that hundreds of millions depend on every day. So, its galling for an ultra-rich celebrity to spread falsehoods about a technology that can feed and fortify the diets of hundreds of millions of poor people around the world.

That wasnt the last we heard from Paltrow. In April 2016, she made a brief cameo in a video sponsored by Just Label It (with Hirshberg taking a star turn) entitled GMO Transparency in the Real World. A harried mother attempts to use her smart phone to scan a QR code on a can of soup to see if the soup contains GMOs (QR codes are anathema to the pro-GMO labeling crowd). As she stumbles to use her smart phone, and her kids smash a watermelon in the aisle, a fresh-faced Paltrow appears from the dairy aisle, asking the distraught mom if she has a scanner on her smart phone that she could use.

Paltrow isnt the only actress to play the Im not an activist, Im a mom card. Around Mothers Day 2015, several B-list mom-actresses appeared in a Moms Against GMOs video produced by another Hirshberg group to talk about GMOs, including Sarah Michelle Gellar, The Talks Sarah Gilbert, UnREALs Constance Zimmer, Once Upon a Times Ginnifer Goodwin, Furious 7s Jordana Brewster, The Biggest Losers Jillian Michaels, Mariel Hemingway and Sharon Osbourne. They pledged to protect their little ones from the dangers of GMOs: This Mothers Day, give moms the right to know whats in the food we feed our kids. Tell the FDA to require GMO labeling.

These actresses are now part of a coordinated, calculated attack on American agriculture and an attempt to stop millions of farmers from using technological tools necessary for their livelihood and Americas food security. They are part of a destructive campaign to hurt American farmers and our overall agricultural and food system.

Since a bill requiring mandatory GMO labels passed Congress and was signed into law by President Obama in August 2016, the GMO labeling groups have been more forthcoming about their true motives. Anti-GMO activist and Institute for Responsible Technology founder Jeffrey Smith, who makes regular appearances on Dr. Oz and other celebrity-type shows, acknowledged their real agenda:

Labeling GMOs was never the end goal for us. It was a tactic. Labels make it easier for shoppers to make healthier non-GMO choices. When enough people avoid GMOs, food companies rush to eliminate them. Labeling can speed up that tipping pointbut only if consumers are motivated to use labels to avoid GMOs.

Some celebrities brazenly profit by spreading misinformation about biotechnology. Jessica Alba parlayed her fame into selling organic, non-GMO products as part owner of The Honest Company. She boasts about the naturality of her products, from organic baby formulameticulously blended using non-GMO, naturally derived, organicto organic tampons to non-GMO lip balm. Many items brandish a non-GMO label. Alba explains her healthy eating habits as trying to have the least amount of GMOs and pesticides you have energy, arent starving and dont have to count calories.

Actor and progressive environmental activist Mark Ruffalo, who does not have a college education, has embraced any number of controversial causes, from fracking to GMOs, where the science is contested. He became a rock star in the anti-GMO community, even confronting Monsanto CEO Hugh Grant in a CBS green room rant before a joint TV appearance and later bragging about it.

You are wrong, he lectured Grant. You are engaged in monopolizing food. You are poisoning people. You are killing small farms. You are killing bees. What you are doing is dead wrong. Its the horrible stuff you guys do that makes you and your company horrible. People like you and your company are horrible because you are horrible.

He has more than 2 million followers on Twitterthats scary. His obsession to demonize genetic engineering took a bizarre turn earlier this year when he started tweeting that the Zika virus was caused by a chemical manufactured by an obscure Japanese company that has a research pact with Monsanto, the bete noire of anti-GMO activists. By doing so, he deflects attention from what experts now say is the only feasible solution to containing Zikathe release of genetically engineered sterile mosquitoes to drive out the poison-carrying ones.

Chef Attack

Many celebrity chefs have taken up the anti-GMO crusade, apparently believing their ability to run a restaurant or cook on television gives them special insight into how food is grown on a farm. Tom Colicchio, the star of Bravos Top Chef program, gathered signatures of more than 4,000 chefs on a petition he delivered to Capitol Hill in March 2016 demanding mandatory GMO labels and rejecting a Senate bill that would have made the labels voluntary.

He claims he only supports the right to know. But his twitter feed is filled with anti-GMO propaganda and like most activists in the GMO labeling movement, he is also broadly against the technology. In a December 2015 op-ed in the New York Times entitled, Are you eating Frankenfish? Colicchio warned readers that the newly approved GE fast-growing salmon could escape enclosed tanks and endanger native speciesclaims multiple US and Canadian regulators have reviewed and rejected as untrue. Colicchio has also come out in opposition to insect-resistant eggplant, grown with government developed seeds distributed free to farmers in Bangladesh, which has reduced the spraying of dangerous chemicals by 85 percent.

Why are celebrities getting so much traction in their campaign against GMOs? They are filling an information void left by the scientific and agricultural communities. Scientists are reluctant to engage the public, either out of trepidation or arrogance, convinced that science will win the day. Infighting has plagued the science communications effort as leaders dispute the best way to fight misinformation from people like Paltrow and Ruffalo.

Some want to take a submissive approach and others want to fight fire with fire. The agricultural community and companies that benefit from genetic engineering arent standing up to defend the technology, either.

While science and farming communicators struggle with how to best educate consumers and the media, organic executives and celebrities are defining the narrative on GMOs. This is not without serious ramifications if we turn away from genetically modified crops. Food prices will rise and farmers will be forced to use more insecticide and more toxic herbicides. Its wonderful to celebrate the performances of TV, movie and music celebrities, but their opinions on science issues are no more relevantnow than they were when they were waiting tables in Hollywood and Nashville looking for a break. Hit the mute button when they start opining on serious policy issues that have considerable consequences for vulnerable people around the world.

Biochemical ‘fossil’ shows how life may have emerged without … – Phys.Org

One major mystery about life's origin is how phosphate became an essential building block of genetic and metabolic machinery in cells, given its poor accessibility on early Earth. In a study published on March 9 in the journal Cell, researchers used systems biology approaches to tackle this long-standing conundrum, providing compelling, data-driven evidence that primitive life forms may not have relied on phosphate at all. Instead, a few simple, abundant molecules could have supported the emergence of a sulfur-based, phosphate-free metabolism, which expanded to form a rich network of biochemical reactions capable of supporting the synthesis of a broad category of key biomolecules.

"The significance of this work is that future efforts to understand life's origin should take into account the concrete possibility that phosphate-based processes, which are essential today, may not have been around when the first life-like processes started emerging," says senior study author Daniel Segr of Boston University. "An early phosphate-independent metabolism capable of producing several key building blocks of living systems is in principle viable."

Phosphate is essential for all living systems and is present in a large proportion of known biomolecules. A sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. Moreover, phosphate is a critical component of adenosine triphosphate (ATP), which transports chemical energy within cells, and a compound called NADH, which has several essential roles in metabolism. But it is unclear how phosphate could have assumed these central roles on primordial Earth, given its scarcity and poor accessibility.

In light of this puzzle, some have proposed that early metabolic pathways did not rely on phosphate. In many of these scenarios, sulfur and iron found on mineral surfaces are thought to have fulfilled major catalytic and energetic functions prior to the appearance of phosphate. One notable origin-of-life scenario suggests that the role of ATP was originally assumed by sulfur-containing compounds called thioesters, which are widely involved in protein, carbohydrate, and lipid metabolism. Despite the availability of iron and sulfur on early Earth, concrete evidence supporting these scenarios has been lacking.

To test the feasibility of the "iron-sulfur world hypothesis" and the "thioester world scenario," Segr and his team used computational systems biology approaches originally developed for large-scale analyses of complex metabolic networks. The researchers used a large database to assemble the complete set of all known biochemical reactions. After exploring this so-called "biosphere-level metabolism," the researchers identified a set of eight phosphate-free compounds thought to have been available in prebiotic environments. They then used an algorithm that simulated the emergence of primitive metabolic networks by compiling all possible reactions that could have taken place in the presence of these eight compounds, which included formate, acetate, hydrogen sulfide, ammonium, carbon dioxide, water, bicarbonate, and nitrogen gas.

This analysis revealed that a few simple prebiotic compounds could support the emergence of a rich, phosphate-independent metabolic network. This core network, consisting of 315 reactions and 260 metabolites, was capable of supporting the biosynthesis of a broad category of key biomolecules such as amino acids and carboxylic acids. Notably, the network was enriched for enzymes containing iron-sulfur clusters, bolstering the idea that modern biochemistry emerged from mineral geochemistry. Moreover, thioesters rather than phosphate could have enabled this core metabolism to overcome energetic bottlenecks and expand under physiologically realistic conditions.

"Before our study, other researchers had proposed a sulfur-based early biochemistry, with hints that phosphate may not have been necessary until later," Segr says. "What was missing until now was data-driven evidence that these early processes, rather than scattered reactions, could have constituted a highly connected and relatively rich primitive metabolic network."

Although this non-experimental evidence does not definitively prove that life started without phosphate, it provides compelling support for the iron-sulfur world hypothesis and the thioester world scenario. At the same time, the study calls into question the "RNA world hypothesis," which proposes that self-replicating RNA molecules were the precursors to all current life on Earth. Instead, the results support the "metabolism-first hypothesis," which posits that a self-sustaining phosphate-free metabolic network predated the emergence of nucleic acids. In other words, nucleic acids could have been an outcome of early evolutionary processes rather than a prerequisite for them.

"Evidence that an early metabolism could have functioned without phosphate indicates that phosphate may have not been an essential ingredient for the onset of cellular life," says first author Joshua Goldford of Boston University. "This proto-metabolic system would have required an energy source and may have emerged either on the Earth's surface, with solar energy as the main driving force, or in the depth of the oceans near hydrothermal vents, where geochemical gradients could have driven the first life-like processes."

In future studies, the researchers will continue to apply systems biology approaches to study the origin of life. "My hope is that these findings will motivate further studies of the landscape of possible historical paths of metabolism, as well as specific experiments for testing the feasibility of a phosphate-free sulfur-based core biochemistry," Segr says. "The idea of analyzing metabolism as an ecosystem-level or even planetary phenomenon, rather than an organism-specific one, may also have implications for our understanding of microbial communities. Furthermore, it will be interesting to revisit the question of how inheritance and evolution could have worked prior to the appearance of biopolymers."

Women’s Health Research Leads to CSU Award, Graduate School – CSUF News

Cal State Fullerton undergraduate Miguel Tellez is an aspiring biomedical researcher who wants to contribute to a better understanding of the human body and use that knowledge to develop novel therapies for human diseases.

To accomplish this goal, he is conducting research in the lab of Maria C. Linder, professor of chemistry and biochemistry, focusing on an aspect of copper metabolism in the body that holds promise for new discoveries.

For his research efforts, Tellez has received a $3,500Howell-CSUPERB Research Scholar Awardfrom the California State University Program for Education and Research in Biotechnology (CSUPERB) for his project on the "Purification and Characterization of a Small Copper Carrier From Blood Plasma A Structural and Physiological Study." CSUPERB partners with the Doris A. Howell Foundation for Women's Health Research to fund undergraduate student research projects on topics related to women's health.

Tellez's research centers on purifying and characterizing a copper-containing component that is present in the blood plasma of most mammals and is elevated in conditions where copper accumulates in the liver. This occurs in certain genetic diseases; it is also common in dogs, who frequently die of copper overload, said Linder.

"My project will allow me to contribute to the field of copper research by bringing to light the identity of small copper-carrying components," said Tellez, a biochemistry major who is on track to graduate in May and is the first in his family to attend college. He plans to begin his doctoral studies this summer in the biochemistry, cellular and molecular biology graduate program at Johns Hopkins University School of Medicine.

Tellez is a research scholar in the Howard Hughes Medical Institute (HHMI) program, led by Linder, and a past scholar in the CSU Louis Stokes Alliance for Minority Participation program.

"He is a young man of enormous potential," Linder said. "His project is exciting and is likely to lead to a breakthrough in the field of copper metabolism."

During pregnancy, copper transport and metabolism during embryogenesis involves aspects of copper metabolism, which are still poorly understood. Yet, every cell in a developing fetus needs copper. Additionally, we have evidence that when women take estrogen-based birth control, it changes the distribution of copper in plasma and elicits large amounts of small copper carrying components. As such, understanding these small copper carriers in the blood plasma is paramount to understanding healthy copper metabolism in women during menstruation and pregnancy.

Because of this research project, I have learned many analytical and biochemical techniques. I've also had the opportunity to present my work at conferences, and by being a part of the HHMI undergraduate program, I learned how to read scientific literature and now better understand other areas of science.

After working with Dr. Linder, I discovered what it meant to be a researcher. She has given me encouragement and has helped me down the academic pathway to earn a doctorate.

In the first grade, I became interested in science after I fed a caterpillar. After some time, it turned into a butterfly, and I was in awe. I wanted to understand what I was seeing. My love for science pushed me to do well in school so I could pursue a career as a scientist.

Anatomy of fear – Inquirer.net

Much has been said and written about the moral aspects of the proposed revival of the death penalty (or lack thereof).

These moral dimensions are important, and need to be discussed even more now that a death penalty bill has been approved on second reading in the House of Representatives. The indecent haste will continue until it is rammed into law, and this could happen very soon.

What I want to tackle is the deterrence argument being used to support capital punishment. Put simply, the argument is that once you execute people for the heinous crimes that are named in the bill, you will strike fear in the hearts of the criminals and would-be criminals, and they will think twice, thrice, many times, before breaking the law. Crime rates would then drop.

But this argument is based on a lack of understanding of what is involved with fear and deterrence, which have been the subject of research by social scientists, natural scientists, and even medical professionals for decades now, and which has been used to back the abolition of the death penalty in many countries. (In the Philippines, then President Gloria Macapagal Arroyo abolished the death penalty based more on her personal religious views.)

Powerful but fleeting

Fear is powerful indeed, a very primitive emotion found throughout the animal kingdom, and that includes humans. Fear evolved early in animals as an instinctive protective mechanism, pushing animals to avoid danger and minimize risks.

But among humans, the processing of fear involves other brain functions. Instinctive responses remain, as when we jump when we see a snake, or when we avoid walking through a dark alley. Note that even at this primitive level, there will be variations among individuals. As parents know all too well, we see differences even among our children. Walang takotno fearwe sigh about a particular child, sometimes said with anxiety because we worry about the kind of extreme risks the child may take, but sometimes also said with pride because we see this fearlessness as an asset.

We know, too, that fear is taught. Overprotective parents can end up raising children who become too fearful of the world because they are taught that it is fraught with danger. A healthier approach is to teach children to take calculated risks, to temper but not suppress their fears.

Finally, fear is learned. We are conditioned into avoiding certain situations, places, creatures like snakes and spiders and cockroaches and people, because of unpleasant experiences. Think of the people we avoid because we have been emotionally battered by them.

The anatomy of fear is complicated in humans because we are rational beings, and I use the term here in a more general way to mean that we reason, sometimes excessively. We respond to our fears no longer based on instinct alone but also with this reasoning, as we argue with each other, and with ourselves, about risks and dangers.

Were usually able to do this well, but sometimes the fears become excessive, creating chronic anxiety and preventing us from functioning well. Psychologists and psychiatrists then come into the picture, helping to process what are now called anxiety disorders and phobias.

But generally, fear runs through our lives as quick, fleeting reactions, which is why the idea of controlling crime by instilling fear just doesnt work. Fear tactics can work only in the short term.

Lets be specific and look now at the death penalty, fear and deterrence.

War on drugs

The restoration of the death penalty is part of the ongoing war on drugs (note how plunder, originally in the list of capital crimes, was removed). But the complicated anatomy of fear becomes even more convoluted when it comes to the use of drugs.

Fear is not processed as fear alone. People think of costs and benefits. Will I be caught, and if I am caught, what will I lose? On the other hand, drugs offer pleasure in many forms, from escaping problems to euphoria.

For the death penalty to work, people have to see evidence that crime does not pay, and this comes about in terms of seeing criminals being apprehended, brought to court, convicted, and the punishment being meted out. We know all too well that at each stage in this continuum, we run into problems: not enough law enforcers, corruption among so-called enforcers, and the courts.

Besides this, the evidence from other countries is that people will avoid crimes if they see justice meted out, and this justice does not have to be the death penalty.

There is also the issue of a fear threshold: What does it take to instill fear? In the Philippines, it takes a lot because our culture is largely fear-based. We are a hala and lagot society, threatening our children constantly with punishment, invoking Tatay, the police, or God (even, lately, President Duterte) as potential punishers. Yet Filipinos learn early enough, even as children, that you can get away with crimeparents drive through traffic lights when there are no traffic enforcers, or even when there are traffic enforcers, because they carry the calling cards of generals and governors.

People know of the many arrests going on, but note that it is mainly the poor being apprehended. There are occasional reports of the high and mighty getting arrested, and their disappearance from the news is interpreted by people as their getting off the hook. Ive seen even the poor carrying a sense of impunity because they know someone who knows someone powerful.

If theres anything that shows why the fear of the death penalty will not work in the war on drugs, its, well, the war on drugs itself. More than 7,000 alleged drug pushers and users have been killed so far, mostly extrajudicially, brutally, in their homes, in front of family and friends. Yet we continue to see people using and selling drugs. Ive lost track, too, of the news reports of relatives, usually wives or mothers of drug dependents, trying to smuggle drugs into prisons to their loved ones.

The extrajudicial killings are far more gruesome than capital punishment, and take place every day. They cast fear, no doubt, with so many correlated stimulithe dark night, the knocking (more often banging) on the doors, but all these do not deter drug-related crimes. Part of conditioning theory is that when you keep trying to reinforce a certain stimuluspositive or negativeyou reach the point of extinction. It no longer works. That is happening today, especially in our poor communities where people have been so brutalized for so long, way before the war on drugs.

Fear is pervasive, but it has not and will not deter crime.

Capital punishment will only provide a new public spectacle, one that might even be, horror of horrors, entertaining.

Gut Microbiota Therapy: the next big thing in Medical Treatments – Inquirer.net

CHECK AND BALANCE. European double-board certified in Nutritional Medicine and Anti-Aging Medicine Dr. Ted Achacoso of BioBalance with microbiota expert Dr. Peter Konturek at the recent 4th World Congress on Targeting Microbiota in Paris, France.

Recent years have seen fecal transplant, or formally Fecal Microbiota Transplantation (FMT), becoming an emerging procedure in the medical field, which basically involves transferring a healthy individuals gut bacteria into a sick persons colon. This may sound surprising to some, but more and more studies reveal the role of gut microbesincluding those in human wastein treating various health conditions, from gastrointestinal problems (ulcers, irritable bowel syndrome, etc.) to non-gastrointestinal diseases such as diabetes, liver disease, allergies, obesity, and autoimmune diseases, among many others. Simply put, a healthy gut is revealed to play a role in both the cure and prevention of such diseases, making the demand for the FMT and other advanced gut health diagnostics and treatment surge across the world in the past two years.

The emerging science of gut health

Addressing gut health for disease prevention and optimization makes sense with the understanding that the gut makes up 70 percent of our immune system. Its thousands of diverse bacterial species are responsible for deciding which substances we consume or gets into our body will be absorbed or secretedprotecting us from infection and regulating our metabolism. A leaky gut would have fewer strains of good bacteria to do such a job, thus the current popularity of FMTs. Today, we can already look into a persons overall gut health and clearly see if there are bad bacteria in your gut or if you lack good bacteria in it that causes you to get sick, become obese, and more, says Dr. Ted Achacoso, a prodigy doctor who isEuropean double-board certified in Nutritional Medicine and Anti-Aging Medicineand heads BioBalance Wellness Institute in the Philippines.The state of your gut says so many things about your entire body.

How the gut influences mood, immunity, aging

Approximately, up to 100 trillion microorganisms per human body colonize the intestinal tract making an additional acquired organ that provides many vital functions to the host. A healthy gut microbiome can be defined by the presence of the various classes of microbes that enhance metabolism, resistance to infection and inflammation, prevention against cancer and autoimmunity, and that positively influence so called brain-gut axis, states a study in the Journal of Physiology and Pharmacology 2015 co-authored by Dr. Peter Konturek, considered the worlds most prominent microbiota expert. The study further discusses the correlation of gut health to peoples behaviors, moods, and aging, among others, only putting more emphasis on the importance of a healthy gut.

Bringing to Manila the worlds expert on gut health

Dr. Peter Konturek, the worlds expert on gut health and FMT, has been thriving as a Professor of Internal Medicine and Gastroenterology at the University Erlangen-Nuremberg in Germany and the Head of the Department of Internal Medicine at the Thuringia Clinic Saalfeld. BioBalance Wellness Institute, a major proponent of health optimization and gut health in the Philippines, is bringing Dr. Konturek to Manila this month for a medical lecture. The lecture intends to impart knowledge on scientific advances on the gut microbiotas influence on health and disease in the hope of expanding the knowledge and influence enthusiasm among medical practitioners and patients. BioBalance has been offering its clients intensive and advance gastro-intestinal and nutritional diagnostics since its inception, making the institute the perfect partner for Dr. Konturek in the Philippines.

Part of Dr. Kontureks lectures in Manila on March 14 will include scientific advances and perspectives on the gut microbiotas influence on peoples brain, mood, immunity, aging, and diseases; a special session on FMT, and practical gut health protocols. Having published over 250 original peer-reviewed publications and more than 15 book chapters, Dr. Kontureks researches are focused on the impact of H.pylori infection in the pathogenesis of peptic ulcer disease and gastric cancer, pathogenesis of inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS), and the role of microbiota in the gastrointestinal tract and interaction with the brain-gut-axis, among others.

Dr. Peter Kontureks medical lecture titled The Investigational New Drug in Your Gut: Advances in Gut Microbiota Science and Fecal Microbiota Transplant Therapy will be held on March 14, 2017 (Tuesday), from 6 to 9 p.m., at JY Halls A & B, Bayanihan Center, Unilab. For more information and seat reservation, please contact BioBalance Institute at (02) 650-4858 or (0917) 521-4860, or e-mailinfo@biobalanceinstitute.com. Limited seats are available.

Netflix Movie ‘Okja’ Teases Uncontrolled Genetic Modification | Inverse – Inverse

The potential and power of genetic engineering looms over the first trailer released for the upcoming Netflix film Okja. Directed by Snowpiercers Bong Joon-ho, the films star is a genetically modified animal who is friends with a young girl and is being hunted by a multinational company. This companys business is genetic modification, and its headed by an icy-blond Tilda Swinton. While Okja is being pegged as science fiction, the fictional part of this film is actually pretty slim: The science that it would take to make such a creature is already in the works.

I took nature and science, Swintons character says in the trailer, clasping her hands. And I synthesized. Shes talking about the massive animal at the heart of the story.

We dont know too much about it: Den of Geek reports that the animal was an experiment that is now growing rapidly, while the films description in Korean describes Okja as somewhere between human and animal. The new trailer only gives us a small look at the creature, whose shape appears to be a pig-hippo crossover with tender brown eyes.

That genetic modification would create a massive creature is not preposterous: Scientists have already used CRISPR technology to increase the size and mass of common animals. In 2015, biotech company AquaBounty Technologies revealed that it genetically modified Atlantic salmon by adding a growth hormone gene and a promoter of an antifreeze gene to the fish. This created much larger salmon that grow at a speed two times faster than average. Double-muscled beagles broke into the CRISPR scene in early 2016, when Chinese researchers from the Guangzhou Institute of Biomedicine and Health announced they used CRISPR/Cas9 gene editing technology to delete the myostatin gene from the normally small-muscled dogs. These beagles not only look like theyre on steroids theyre stronger and can run faster than their unmodified peers.

Real-life animals that seem more suited for a fantasy novel arent out of the question either: In a 2016 essay in The American Journal of Bioethics, professors Hank Greely and R. Alta Charo argue that creating a dragon yes, a dragon wasnt impossible with CRISPR technology. Sure, physics would prevent it from actually spitting out fire, but a very large reptile that looks at least somewhat like the European or Asian dragon (perhaps with flappable if not flyable wings) could be someones target of opportunity, they write.

And if Okja is indeed somewhere between human and animal and this is a literal explanation, rather than an anthropomorphic sentiment the science is almost there as well. At the end of January, scientists declared they had created pig-human chimeras. These embryos were less than 0.001 percent human and were created with the hope that they could one day allow us to grow human organs inside animals not actual pig-humans. Still, its proof that what seemed like science fiction only decade prior can actually become a reality. Okja the film may seem like science fiction when its released this June, but it could very well be pegged as a documentary in the years to come.

FDA, EPA approve 3 types of genetically engineered potatoes – CBS News

BOISE, Idaho -- Three types of potatoes genetically engineered to resist the pathogen that caused the Irish potato famine are safe for the environment and safe to eat, federal officials have announced.

The approval by the U.S. Environmental Protection Agency and the U.S. Food and Drug Administration late last week gives Idaho-based J.R. Simplot Company permission to plant the potatoes this spring and sell them in the fall.

New research shows that women who eat a lot of potatoes may be more likely to develop gestational diabetes. CBS News' Danielle Nottingham reports...

The company said the potatoes contain only potato genes, and that the resistance to late blight, the disease that caused the Irish potato famine, comes from an Argentine variety of potato that naturally produced a defense.

The three varieties are the Russet Burbank, Ranger Russet and Atlantic. Theyve previously been approved by the U.S. Department of Agriculture.

All three varieties have the same taste and texture and nutritional qualities as conventional potatoes, said Simplot spokesman Doug Cole.

Late blight thrives in the type of wetter conditions that led to the Irish potato famine in the 1840s. Potatoes were a main staple, but entire crops rotted in the field. Historical records say about a million people died of starvation and disease, and the number of Irish who emigrated might have reached several million.

Potatoes in modern times are considered the fourth food staple crop in the world behind corn, rice and wheat. Late blight continues to be a major problem for potato growers, especially in wetter regions. Fungicides have been used for decades to prevent the blight.

Simplot says the genetically engineered potatoes reduce the use of fungicide by half.

The company said the potatoes will also have reduced bruising and black spots, enhanced storage capacity, and a reduced amount of a chemical created when potatoes are cooked at high temperatures thats a potential carcinogen.

Foodies will welcome any word that things once thought to be bad for your health might actually be good. That applies to potatoes. Serena Altschu...

Conventional potatoes can turn a dark color when cooked after they were kept cold for too long, a problem Simplot said the three new varieties reduce. The company also said the enhanced cold storage will likely have significant ramifications for the potato chip industry by reducing trucking costs.

There is no evidence that genetically modified organisms, known as GMOs, are unsafe to eat, but for some people, altering the genetic code of foods presents an ethical issue. McDonalds continues to decline to use Simplots genetically engineered potatoes for its French fries.

Simplot often notes the potatoes contain only potato genes, and not DNA from an unrelated organism. Organisms that contain DNA from an unrelated organism are defined as transgenic.

The Washington state-based Non-GMO Project that opposes GMOs and verifies non-GMO food and products said Simplots new potatoes dont qualify as non-GMO.

Play Video

By some estimates, 80 percent of all processed foods - cereals, baby formula, canned soups and more - contain at least one genetically-modified o...

There is a growing attempt on the part of biotechnology companies to distance themselves from the consumer rejection of GMOs by claiming that new types of genetic engineering ... are not actually genetic engineering, the group said in a statement.

The most recent federal approvals apply to Simplots second generation of Innate potatoes. The first generation that went through the federal approval process didnt include protection from late blight or enhanced cold storage.

The first generation of Innate potatoes has been sold in stores under the White Russet label. Cole said the company hasnt decided how it will market the second generation.

The company is currently at work on a third generation that Cole said will have protections against additional strains of late blight, all coming from genes within the potato species.

Genetically Engineered Super Pigs Could Make Your Bacon Better – Gizmodo

These piglets could be protected from an infection that costs the swine industry billions each year. Image: Laura Dow, The Roslin Institute

For pig farmers, Porcine Reproductive and Respiratory Syndrome is a disaster. Once dubbed the mystery swine disease, it emerged in the late 1980's on farms in Europe and the US and spread rapidly, causing piglets to die and adult pigs to be afflicted with fever, lethargy, and respiratory distress. It is a major problem facing pig farmers, costing the industry billions each year.

Now the same research organization that brought us Dolly the sheep thinks it may have a solution: Scientists at University of Edinburghs Roslin Institute have genetically engineered pigs to be resistant to the virus that causes the disease.

In a new paper published in PLOS Pathogens, the scientists reported that they used the genetic engineering technique CRISPR-Cas9 to delete a small slice of one particular gene that previous studies have shown plays a key role in enabling the PRRS virus to establish an infection. The edits were made early in the embryonic stage, removing the bit of gene in a laboratory while the piglets were still merely zygotes then implanting the embryos into mother pigs. Litters of healthy piglets with that genetic tweak have since been born, and some have even gone on to have their own litters with the inherited edit.

Early tests found that cells from the pigs were entirely resistant to infection from both major strains of the virus. The next step will be to test whether the pigs themselves are resistant to infection when actually exposed to the virus.

The study builds on earlier research that has showed pigs that entirely lack a protein called CD163 do not become ill when exposed to the PRRS virus. CD163 exists on the surface of immune cells called macrophages, and its presence seems to help PRRS take hold in a pigs body and spread. So the Roslin Institute researchers simply deleted a portion of the CD163 gene. So far, it has not shown any signs of adversely affecting the pigs.

In both the US and Europe, regulations and attitudes toward GMOs could make it hard to make such pigs commercially available. But if it works, the super pigs are sure to be in demand among both pig farmers and lovers of bacon.
