First real indicator of longevity in mammals discovered

ScienceDaily (Sep. 27, 2012) A team of researchers from the Spanish National Cancer Research Centre (CNIO), headed by CNIO Director Mara Blasco, has demonstrated in a pioneering study on mammals that longevity is defined at a molecular level by the length of telomeres. The work -- which is published September 27 in the online edition of the journal Cell Reports -- opens the door to further study of these cellular components in order to calculate the rate at which cells age and thus be able to determine life expectancy for a particular organism.

Chromosomes -- the cellular containers holding the genetic information in living creatures -- have repetitive sequences of DNA at their extremities called telomeres. These sequences act as hoods that protect the genetic material in the face of any external agent which might damage it and compromise the function of the cells.

Several transversal population studies -- measuring telomere length once over time in a large group of individuals -- show a relationship between the length of the telomeres and the risk of suffering illnesses -- cardiovascular disease or cancer, for example.

Until now, however, the use of telomeric measurements to predict real life expectancy in mammals had not been evaluated.

"In the transversal studies, it appears that individuals with short telomeres have a significantly increased probability of developing illnesses, including cancer. But this information is not applicable to a specific individual," says Blasco.

To determine a real aeing prediction method, the authors of the present study have carried out longitudinal studies of telomere length in mice, in which a single individual is followed over a period of time.

After taking periodic blood samples from the same individual, from which cells were extracted for study, they found that those mice which managed to live longer were not the ones that had longer telomeres at any given age but those in which showed less telomeric shortening over time.

"The important thing is not so much the long telomeres at any given time as the tendency or the evolution of the length of the telomeres over time," says Elsa Vera, lead author of the study.

With this study, Blasco's team suggests using mice as an animal model in longitudinal studies that allow for health prognoses in humans. Blasco says that: "while telomere length in normal mice is much greater than in humans, we have found, surprisingly, that the telomere shortening rate in mice is 100 times faster than in humans, so the old dogma of normal mice not getting old due to the shortening of their telomeres is wrong."

This study further opens the possibility of studying, via the longitudinal examination of these genetic guardians, the real effect of lifestyle choices such as diet, smoking or exercise on individual aging rates.

Many female brains contain male DNA

In the first study of its kind, researchers have discovered that male DNA is commonly found in the brains of women a finding that could hold important implications for diseases like Alzheimers disease and cancer.

Male DNA is likely transferred to female brains during pregnancy, according to researchers from the Fred Hutchinson Cancer Research Center in Seattle. During this time, mothers and fetuses exchange and harbor genetic material and cells in a phenomenon called microchimerism.

This means, if a mother is pregnant with a boy, she will end up with male DNA in her system potentially for the rest of her life. If the fetus is female, the mother will end up with genetic material from her daughter, though it is difficult for researchers to distinguish between two sets of female DNA in microchimerism studies.

What this means for treating diseases

Prior studies have observed fetal DNA in many other of the mothers tissues and organs, but this is the first to confirm fetal cells can cross the blood-brain barrier and reside in the mothers brain beyond pregnancy.

We were interested in looking at the human brain because its never been looked at before, and it was really unknown if the cells of fetal origin could reach the brain, study senior author Dr. Lee Nelson, a member of the Fred Hutchinson Cancer Research Center and professor of medicine at the University of Washington, told FoxNews.com. Nelson and her colleagues performed autopsies on 59 brains of deceased females and detected male microchimerism in 63 percent of them.

Male microchimerism was distributed across multiple regions of the female brain, including those affected by dementia, and could persist for decades potentially even an entire human lifespan. According to the study, the oldest female with microchimerism detected in her brain was 94.

The question naturally arises what role might the cells have in benefiting health and what role they play in diseases, Nelson added.

The researchers hope further studies on microchimerism might shed new light on various diseases that affect the brain, such as Alzheimers, Parkinsons or even brain tumors.

These cells have access to the brain could help us understand different treatment options for diseases that arent well treated, Nelson said. Its a very exciting new area that opens up different possibilities, such as, what if these cells have anti-tumor potential? For example, glioblastomas are deadly tumors, (which) have poor treatment options. Were very much in need of new potential options.

Bearing Sons Leaves Male DNA Traces in Mom's Brain

By Melissa Lee Phillips, ScienceNOW

Giving a whole new meaning to pregnancy brain, a new study shows that male DNA likely left over from pregnancy with a male fetus can persist in a womans brain throughout her life. Although the biological impact of this foreign DNA is unclear, the study also found that women with more male DNA in their brains were less likely to have suffered from Alzheimers disease hinting that the male DNA could help protect the mothers from the disease, the researchers say.

During mammalian pregnancy, the mother and fetus exchange DNA and cells. Previous work has shown that fetal cells can linger in the mothers blood and bone for decades, a condition researchers call fetal microchimerism. The lingering of the fetal DNA, research suggests, may be a mixed blessing for a mom: The cells may benefit the mothers health by promoting tissue repair and improving the immune system but may also cause adverse effects, such as autoimmune reactions.

One question is how leftover fetal cells affect the brain. Researchers have shown that fetal microchimerism occurs in mouse brains, but they had not shown this in humans. So a team led by autoimmunity researcher and rheumatologist J. Lee Nelson of the Fred Hutchinson Cancer Research Center in Seattle, Washington, took samples from autopsied brains of 59 women who died between the ages of 32 and 101. By testing for a gene specific to the Y chromosome, they found evidence of male DNA in the brains of 63 percent of the women. (The researchers did not have the history of the womens pregnancies.) The male DNA was scattered across multiple brain regions, the team reports online today in PLoS ONE.

Because some studies have suggested that the risk of Alzheimers disease (A.D.) increases with an increasing number of pregnancies, the team also examined the brains for signs of the disease, allowing them to determine whether A.D. correlated with the observed microchimerism. Of the 59 women, 33 had A.D. but contrary to the teams expectation, the women with A.D. had significantly less male DNA in their brains than did the 26 women who did not have A.D..

Whether that correlation means that fetal male DNA helps protect women against A.D. is unclear, however. To me, this suggests that the presence of fetal cells in the female brain prevents disease, says cardiologist Hina Chaudhry of Mount Sinai School of Medicine in New York City.

In a study published online in Circulation Research late last year, Chaudhry and colleagues found that fetal cells in mice migrated to the mothers heart, differentiated into functioning cardiac cells, and accelerated repair to damaged heart tissue. So, Chaudhry says, a similar thing could be happening when fetal cells migrate to the brain. I would bet these cells are getting into the maternal brain and are able to differentiate into neurons.

A 2010 study in Stem Cells and Development showed that fetal cells can migrate to the brain of a mother mouse and mature into neurons, Nelson says. But, she adds, it remains unclear if something similar is happening in humans and its also difficult to reach any firm conclusions about a potential link between microchimerism and A.D. Part of the problem is that her team had little information about the pregnancy histories of the women in their study. We have to say we really dont know, she says. I hope that kind of work can be done in the future, but its very difficult to do with human samples.

New drive to take criminals' DNA

27 September 2012 Last updated at 13:20 ET

Police forces in England and Wales have begun a large-scale operation to collect DNA samples from about 12,000 serious offenders who are not on the national DNA database.

Operation Nutmeg will see officers collect swabs from sex offenders and murderers living in the community.

Criminals are often not on the database if they were convicted before 1994, when sample-taking became routine.

The scheme has been launched after a successful pilot exercise in Hampshire.

Police hope the collection of thousands of new samples could help to solve so-called cold-cases, where a new sample is linked to a past crime.

Speaking at a briefing on Thursday, Amanda Cooper, director of information, science and technology at Thames Valley Police, said officers would approach individuals between now and next summer to collect the samples.

Police forces have been given lists of offenders living in their areas and will work though them to collect the samples.

The lists have been drawn up based on information from the Police National Computer, which was first used in the 1970s.

Alex Marshall, the chief constable of Hampshire police, said 167 samples were taken from a list of 471 convicted criminals during the pilot operation.

Biology megaprojects offer ‘diminishing returns,’ warns ex-National Academy of Sciences chief

OTTAWA The editor of the worlds best-known science journal has issued a call to avoid getting carried away with massive human biology projects that show clear signs of diminishing returns.

Bruce Alberts is editor-in-chief of Science magazine, and a biochemist by training.

What triggered his warning, published Wednesday in an editorial, is the latest biology megaproject: 10 years of work by 442 scientists to create an encyclopedia of DNA elements.

Biology has megaprojects of all sorts. There was the 15-year Human Genome Project, deciphering three billion pieces of our DNA code.

Equally massive studies keep spinning off: proteomics (identifying all the proteins in cells), transcriptomics, epigenomics and metabolomics see the creation of encyclopedia-sized works by hundreds of researchers at many universities and governments, and their staffs.

Whats wrong with that? Alberts warns that the governments funding these projects are producing mountains of data, but not enough understanding.

As a coauthor of a textbook in cell biology that is updated at 5-year intervals, I am painfully aware of the huge gap that remains in our understanding of even the simplest cells, he writes.

For instance, he argues, after 50 years of using the E. coli bacterium as a model, nearly a quarter of its more than 4,000 proteins have unknown functions. He calls this very sobering.

There are clear signs of diminishing returns from the megaprojects, he said. But the culture supporting them remains difficult to stop, and he says its grabbing all the available money.

Alberts is one of the worlds most influential figures in science policy, a past president of the U.S. National Academy of Sciences with a global audience. Hes also a divergent thinker who has railed against the gobbledygook of science jargon and pleaded with researchers to speak (and write) plainer English.

Ember Therapeutics Announces Cell Publication of Key Data Showing TRPV4 Inhibition Activates Brown/Beige Fat and …

BOSTON--(BUSINESS WIRE)--

Ember Therapeutics, Inc., a company harnessing breakthroughs in brown fat biology and insulin sensitization to revolutionize the treatment of metabolic disease, today announced the publication of key preclinical data demonstrating that inhibition of the Transient Receptor Potential Vanilloid (TRPV) family of ion channels - specifically TRPV4 - resulted in activation of brown/beige fat and protection from diet-induced obesity, inflammation and insulin resistance. Ember holds an exclusive option to license these TRPV4 findings and technology.

This breakthrough TRPV4 research was led by Ember co-founder Bruce Spiegelman, Ph.D., professor of cell biology at Dana-Farber Cancer Institute and Harvard Medical School, in collaboration with fellow company co-founder Patrick Griffin, Ph.D., professor and chair of the department of molecular therapeutics and director of the Translational Research Institute at The Scripps Research Institute. Additional co-authors on the paper included researchers from Boston Childrens Hospital, Duke University Medical Center and Massachusetts General Hospital. The research was supported by grants from the National Institutes of Health (NIH).

This research is exciting in that it looks at the role of TRPV4 and, from high throughput screening to in vivo pharmacological inhibition, demonstrates the important impact it could have on obesity and metabolic disease, said Louis Tartaglia, Ph.D., president and interim chief executive officer of Ember. Not only do these findings identify TRPV4 as a compelling therapeutic target, but they continue to build out our understanding of the role of brown fat in humans and in developing novel brown fat treatments for metabolic disease.

The publication details how researchers first developed a high throughput screen to identify molecules that increase PGC1 gene expression in white fat cells. PGC1 is a key regulator of energy metabolism and drives the browning of white fat and increased thermogenesis. The researchers then demonstrated that small molecule inhibition of TRPV4 not only increased PGC1 levels, but also expression of UCP1 - a gene that is specifically expressed in brown/beige fat. In cultured fat cells, blocking TRPV4 resulted in reduced expression of multiple proinflammatory genes that are involved in the development of insulin resistance. Finally, preclinical mouse models using either mice with a null mutation for TRPV4 or wild-type mice treated with a TRPV4 antagonist demonstrated increased thermogenesis in brown/beige fat tissues and protection from diet-induced obesity, inflammation and insulin resistance. Collectively, these findings demonstrate the compelling therapeutic potential of small molecule TRPV4 inhibition in obesity, type 2 diabetes and other metabolic diseases.

The paper, TRPV4 is a Regulator of Adipose Oxidative Metabolism, Inflammation and Energy Homeostasis, is now available online and will publish in the print edition of Cell on September 28.

'Online freedom sees setbacks'

Share

ARE THE DAYS OF online freedom numbered? Screen grab from YouTube (TechfluffTV)

WASHINGTON, USA - Online freedom has suffered setbacks in many countries but also some gains amid the Arab Spring uprisings and political upheaval in parts of the world, a new study showed.

The report by the research group Freedom House found that 20 countries "experienced a negative trajectory since January 2011" as authorities used newer, more sophisticated controls to quell dissent on the Internet.

"The findings clearly show that threats to Internet freedom are becoming more diverse," said Sanja Kelly, project director at Freedom House and co-author of the report released Monday covering the period from January 2011 to May 2012.

"As authoritarian rulers see that blocked websites and high-profile arrests draw local and international condemnation, they are turning to murkier but no less dangerous methods for controlling online conversations."

The study found that Estonia had the highest level of online freedom among the 47 countries examined, while the United States ranked second.

Iran, Cuba and China received the lowest scores and 10 other countries received a ranking of "not free" Belarus, Saudi Arabia, Uzbekistan, Pakistan, Thailand, Vietnam, Myanmar, Ethiopia, Bahrain and Syria.

The worst declines, according to the report, were in Bahrain, Egypt and Jordan, reflecting "intensified censorship, arrests and violence against bloggers."

It said online freedom was also hurt in Mexico "in the context of increasing threats of violence from organized crime," and in Ethiopia, "possibly reflecting a government effort to establish more sophisticated controls before allowing access to expand."

A cockroach could save your life

Researchers from North Carolina State University have turned the cockroach - perhaps the world's most despised insect - into an emergency rescue worker.

The idea is to develop a cyborg cockroach, one that could be remotely controlled.

With a camera on its back, thecockroach could enter and maneuver through tiny crevices, searching for survivors from an earthquake or another disaster.

Search and rescue workers often have difficulty investigating these areas, and this new and improved (though still disgusting) little guy could be one way to locate survivors.

Reuters reports on how it works:

Sharks that stray too close to beaches to be killed

Colin Barnett, Western Australia premier, unveiled a Aus$6.85 million (4.4 million) package in shark mitigation strategies, including a track, catch and destroy programme, in the wake of five fatal attacks over the past year.

A further Aus$2 million would be set aside for shark research, while the remaining funding would be devoted to extra jet-skis for life guards, a study and trial of enclosures and a smartphone application for shark alerts.

"These new measures will not only help us to understand the behaviour of sharks but also offer beachgoers greater protection and confidence as we head into summer," said Barnett.

Western Australia's government has come under growing pressure to increase protection measures after the five deaths over the past year an unprecedented number for such a short period.

The most recent fatality was in July, when a surfer was bitten in half in a savage attack near Wedge Island, north of Perth, with another mauled but escaping alive last month at far-flung Red Bluff.

Most fatal attacks in the region involve great whites, among the largest shark species in the world and made famous by the horror movie "Jaws". They can grow up to 20 feet and weigh up to two tonnes.

Sharks are common in Australian waters but deadly attacks have previously been rare, with only one of the average 15 incidents a year typically proving fatal.

Experts say the average number of attacks in the country has increased in line with population growth and the popularity of water sports.

Blue flag fears after poor summer

Please turn on JavaScript. Media requires JavaScript to play.

Up to a quarter of Welsh beaches are "at risk" of losing their Blue Flag award next year

Almost a third of Wales' blue flag beaches could be stripped of their status due to the poor summer weather.

Environment Agency Wales (EAW) said the wettest UK summer in 100 years has resulted in a rise in bacteria levels in the water due to sewage pollution.

Businesses have expressed fear of a drop in trade if the blue flag status of their local beach is lost.

From next year, new rules will see water quality for blue flags assessed over four years rather than one.

The blue flag award is issued by the Foundation for Environmental Education (FEE), which rates beaches on categories including facilities, environmental management, water quality and all-round cleanliness.

The heavy rain this summer has not only caused significant flooding and problems for farmers and tourism, it has also affected bathing waters at some of our beaches

Forty three beaches and five marinas in Wales earned the status in 2012, two more than in 2011.

The danger lurking off Brazil's beaches

27 September 2012 Last updated at 07:24 ET

Brazil's northeast coast boasts warm waters and beautiful beaches. But the coastal waters are home to many aggressive sharks, and in the last 20 years a spate of attacks has made this one of the most dangerous places in the world to swim. Rob Sawers reports.

In the last week of August, the body of Tiago Jose de Oliveira da Silva, 18, was found in the sea just south of Recife, in north-eastern Brazil. An autopsy ruled he had been killed by sharks.

His death was the 56th shark attack in Recife in 20 years. What is so shocking about Recife's attacks is that so many of them are fatal - 21 of the 56, a death rate of about 37%. This is much higher than the worldwide shark attack fatality rate, which is currently about 16%, according to Florida State Museum of Natural History .

According to Dr Rosangela Lessa of the Federal Rural University of Pernambuco (UFRPE), and president of the state's team trying to reduce shark attacks, the blame lies with recent environmental disturbances in the region. It is also because there are lots of beachgoers - and lots of aggressive sharks - sharing the water.

Scientists believe most of these attacks are committed by two species - bull sharks and tiger sharks - but forensic evidence has only been able to confirm the species responsible in eight of these attacks.

Bull sharks are considered the be one of the most dangerous shark species, with many proven attacks against man.

There are almost two million people in Recife and surrounding areas, and there are many beaches conveniently located in and around the city. But, some 700 metres off the coast lies a deep trench running parallel to the beaches near the city.

Sharks use this trench as a migratory route and emerge from it to hunt in the shallows.

It is Recife's Port Suape, though, that many see as the biggest cause of the recent attacks. Located 20km (12 miles) south of Boa Viagem Beach, where most of the attacks have occurred, the port has been the cause of much disturbance for marine life along the coast and the nearby estuaries.

Aerospace Materials protect surfaces against chafing, abrasion.

GORE SKYFLEX Aerospace Materials for anti-chafe applications helps minimize vibration force and reduce the abrasive effects of foreign debris between surfaces. In applications such as access panels, fuel bladders, tail booms, and transmission panels, mechanical wear from vibration can cause small particles to become trapped between the interfaces, resulting in chafing, pitting, and scoring. Gores soft durable materials are chemically inert and resistant to aircraft fluids, thereby minimizing potential corrosive effects.

GORE SKYFLEX Aerospace Materials for edge protection are abrasion-resistant and engineered specifically to prevent abrasion and cut-through damage from composite floorboard edges and reduce the likelihood of corrosion. More durable than fiberglass tapes, these materials protect edges by isolating carbon and other components that are galvanically dissimilar. These lightweight, highly conformable materials are easy to install because of their single-component construction, and they simplify maintenance because they are easy to remove for inspection.

According to Ross Livington, Gores global product specialist for GORE SKYFLEX Aerospace Materials for surface protection, the mechanical properties of these materials have been engineered to withstand wear and increase the durability of their protective performance. With decades of experience in the aerospace industry, we understand the importance of reliability and aircraft availability. Our highly conformable materials reduce downtime of the aircraft through their long-term performance, and with easy installation the aircraft availability can be improved.

Robots to help stroke patients

Starting in October, Phoenix-based neurology specialist Dr. Bart Demaerschalk will be able to roam the halls of Casa Grande Regional Medical Center, look into the eyes of stroke patients, diagnose conditions and consult with colleagues.

And he'll do it all from Phoenix using a joysticklike tool while looking at his computer monitor. His patients will be looking right back at him.

"I use a joystick device," he said. "It's much like a video game. It allows me to drive the robot in another environment."

Demaerschalk is medical director of the Mayo Clinic's telestroke system, which consists of a mobile robot doctors can control, adjust and speak through. ER doctors in Casa Grande will be able to contact the Mayo Clinic staff on a telestroke hotline.

The hospital, at 1800 E. Florence Blvd., in Casa Grande, is 43 miles from Marana.

Using telestroke, doctors can travel with other members of the health-care team throughout the hospital, moving from room to room and through elevators.

The Mayo Clinic developed the technology to care for stroke patients in rural settings. Demaerschalk said stroke neurologists and doctors working at the remote sites have used telestroke together to diagnose strokes with 96 percent accuracy in 1,000 cases.

The Casa Grande hospital is one of 11 in the network. The Mayo Clinic started the program in 2005.

The technology is already in hospitals in Bisbee, Cottonwood, Flagstaff, Globe, Kingman, Parker, Phoenix, Show Low, Yuma and Phoenix, as well as St. Joseph, Mo.

In addition to seeing patients himself, Demaerschalk and six other doctors in a rotation will have access to patients' brain scans to look for damage from blocked arteries or hemorrhages.
