Human Side of Mars Missions the Focus of Florida Tech Workshop – Florida Tech Now

Posted: May 18, 2017 at 1:56 pm

MELBOURNE, FLA. With the focus so often on the rockets and technology required to reach Mars, less attention has been paid to another component critical to the success of future missions: the crewmember.

That changes later this month when researchers from across North America gather at Kennedy Space Center Visitor Complex on Floridas Atlantic coast for the Mars Mission Social Sciences Workshop.

Co-hosted by Florida Institute of Technologys Buzz Aldrin Space Institute and its Institute for Cross Cultural Management, the two-day event May 30-31 will bring together leading scholars from a variety of social science disciplines to develop common characterizations of the psychological, sociological and human performance challenges associated with permanent Mars colonization, and to consider the approaches and research needed to cope with these challenges.

The workshop opens with a welcome from Andrew Aldrin, director of the Buzz Aldrin Space Institute, and then shifts into sessions based on overarching topics: psychiatric health and disorders; group and team dynamics; international and cultural issues; human factors and human-centered design; and historical, sociological, and anthropological perspectives on colonization.

Within each session will be short presentations and panel discussions. Those are scheduled to include:

The trailblazing men and women who will one day travel to Mars face a long, arduous journey, Wildman said. We are hopeful that our research and shared scholarship will allow us to develop ways to improve the probability of making those journeys successful and safe.

The second day will be centered around forming small, multidisciplinary working groups focused on developing clear research agendas within the various sub-topics identified as critical during the first day. The second day will begin with a thorough pre-brief providing instructions and clear criteria for the outcomes of the working groups, and will conclude with formal brief-backs from each of the working groups, which should facilitate a productive wrap-up discussion and next steps.

The Mars mission will undoubtedly be an international one. Like many large scale challenges, the Mars mission is too complex for any one organization, or any one nation, to accomplish alone, said ICCM Executive Director Richard Griffith. Cultural competence of the crew and support team will be a key variable in mission success.

Wildman added, The intended final product of the workshop is a research agenda report that is truly integrative and interdisciplinary.

How to die on Mars, according to one scientist – Blastr

Posted: at 1:56 pm

Wed, May 17, 2017 10:02am

If youve ever read1,001 RidiculousWays to Die, then you already know every sorry and often bizarre ending you could possibly encounteron Earth. Planetary scientist Pascal Lee of NASAs Ames Research Center and the SETI Institute believes that Mars is crawling with much worse fates than having a piano fall on your head.

Mars colonization, or at least putting boots on the Red Planet, has lately been a topic as burning as the planets extreme radiation, but it seems one thing no one wants to discuss (at least on the internet) is how potential Martian citizens could perish. And this is in addition to the looming specter of health risks for even seasoned astronauts. Glaze-eyed space cowboys may want to believe in a Jetsons future, but Lee is skeptical. If your equipment glitches without a viable solution 33.9 million miles away home, you could end up buried in six feet of red dust with a scrap of space junk as a grave marker.

"If you are unprotected on Mars your blood would boil, even at ambient temperature," said Lee, referring to the low pressure of the planets dangerously thin atmosphere. Try a hundred times thinner in comparison to Earth. Meaning any Martian gases that got into your bloodstream would dissolve into bubbles not unlike soda fizz. Except, like some twisted science fair experiment, you would turn into something of a human soda can and actually fizz to death.

Radiation is the the most obvious lethal force on Mars, so much so that there was actually a study done to determine whether The Martians fictional NASA astronaut would actually survive given he touched down on a mission in the year 2035. Most of the Martian atmosphere has been brutally stripped away by solar winds. Unlike Earth, Mars is missing a strong magnetic field, which leaves it vulnerable to solar storms. No magnetic field and almost no atmosphere mean the surface is being showered with solar particles and cosmic rays. The intense radiation that gets through will kill you in months. Cause of death: radiation poisoning or cancer.

Mars is also freezing. At its equator, a summer day that registers at 70 degrees Fahrenheit is actually considered a temperature high. Even in the middle of July, what seems like a warm, breezy weather (those breezes are probably deadly solar winds) will plunge to negative 80 degrees Fahrenheit. Youll end up as a human popsicle if your space suit doesnt have the right insulation. Cause of death: hypothermia.

The perils of the Red Planet dont stop there. What is left of the atmosphere is almost completely carbon dioxide. Compare the 78 percent nitrogen and 21 percent oxygen we breathe in on Earth to a lethal 95 percent carbon dioxide. If your oxygen supply ran out, it would be like inhaling exhaust fumes. Cause of death: hypoxia.

Speaking of things you shouldnt ever be breathing, youd better keep your helmet screwed on at all times because dust is floating around positively everywhere. Breathe it in and your lungs will eventually fail from all the abrasive and fine-grained particles that will scrape relentlessly at the insides of your lungs. Not to mention this dust is highly toxic. Cause of death: poisoning and pulmonary hemorrhage.

NASA aims to make sure the Red Planet wont turn into the Red Death. While it has its sights set on blasting off to Mars approximately by the time The Martians Mark Watney landed, and while the whole world (and the whole internet) is impatient to see a Mars mission happen, the space agencys priority is developing over three dozen new technologies to send astronauts back to Earth as healthy as they were before takeoff.

NASA Is Sending A Lander To Search For Life On Jupiter’s Icy Moon – The Daily Caller

Posted: at 1:55 pm

NASA will hold a competition to develop scientific instruments for a potential mission to land on Jupiters icy moon, Europa.

The space agency requested any scientific instruments developed during the contest be geared towards searching for alien life or towards assessing the prospects for colonization.

The possibility of placing a lander on the surface of this intriguing icy moon, touching and exploring a world that might harbor life is at the heart of the Europa lander mission, Thomas Zurbuchen, associate administrator of NASAs Science Mission Directorate, said in a press statement Thursday.

We want the community to be prepared for this announcement of opportunity, because NASA recognizes the immense amount of work involved in preparing proposals for this potential future exploration, Zurbuchen said.

NASA began designing and testing its Europa Clipper space probe, which is expected to launch sometime in the early 2020s. The Europa Clipper will also investigate the icy moons habitability for human and alien life, but will not land. NASA proposed Europa lander will follow the probe.

Europa may have watery oceans below its ice similar to those of Earths, which may be kept warm by complex gravitational interactions and the moons core. The oceans may be warm enough to support some type of alien life.

Republican lawmakers asked NASA to add more instruments to the Europa Clipper so it can investigate plumes of water ice ejected from Europas surface and deploy several small satellites, which would orbit the moon.

Lawmakers asked NASA to consider a future Europa lander mission in 2016, but the Obama administration wanted to reject the mission and strip down the Europa Clipper to increase funding for Earth sciences, including global warming.

President Barack Obama requested NASAs mission to Europa receive only $49.6 million in 2017, far less than the $175 million the mission got from Congress in 2016.

Beyond Earth Offers Titan as a More Sensible Option for Human Colonization – Apex Tribune

Posted: at 1:55 pm

Beyond Earth presents Titan as a better alternative for human colonization in space

The entire scientific world is currently debating on the best strategies for NASAs future manned mission on Mars. However, a new book called Beyond Earth argues that setting up a human colony so close to Earth is much too challenging. Therefore, it suggests a different destination for a possible long-term human settlement: Titan, the biggest of the Saturns moons.

This might sound like an insane proposal, since Saturn is quite far away and an unmanned spacecraft took seven years just to reach the planet. However, the book is not just a piece of science-fiction literature. One of the authors is Amanda Hendrix, a scientist from the Jet Propulsion Laboratory and the Planetary Science Institute.

For the book, Hendrix collaborated with Charles Wohlforth, an environmentalist with valuable knowledge on how to make hostile conditions suitable for life. Together, they interviewed many scientists at NASA on the impacts extensive space travel has on humans or how technology might evolve.

What they obtained was a bundle of information on our present and future resources for space travel, combined with a little fiction. Also, the book is a bit easier to understand than any other series documenting the NASA attempts to develop a human exploration mission.

The two authors argue against the current destinations established by NASA for the manned missions. Both the Moon and Mars do not have atmospheres and are abundant in harmful variation. Therefore, any colonies might have limited access to the surface and would have to build everything underground.

On the other hand, Titan has an atmosphere which protects the surface from radiation. Also, it would defend any structures from collapsing. With enough protective clothing and an oxygen mask, humans might be able to venture on the surface of Saturns moon. Besides, they might even benefit from water supplies from the ocean hidden underground.

The authors admit that the distance might be a problem, but they say that those sent to explore Mars would face the same problems posed by long-distance space travel. However, the evolution of technology should allow for the exploration of more distant worlds. Image Source: JPL NASA

Facts, fears and the future of food: Asheville talks about genetic engineering – Mountain Xpress

Posted: at 1:55 pm

Asheville-based director and producerJeremy Seiferts 2013 documentary film GMO, OMG highlighteda major concern about the manipulation of the food supply the belief that genetically modified organisms are dangerous.

In 2015, Mountain Xpress reported how local restaurants were seeing an increased demand for non-GMO foods. Until aGMO labeling bill was signed into law in July 2016, locals likeThe Market Placechef and ownerWilliam Dissenwere vocal, not so much about the dangers of GMOs, but about the importance of transparency when it comes to genetic engineering in our foods.

On Saturday, May 20, GMO Free NC will host the sixth annual March Against Monsanto, an Asheville public protest that organizers say aims to raise awareness of the dangers of genetically modified organisms to our food, to our health, our childrens health and that of all living things on the planet.

Even theNational Academy of Sciences,the agency responsible for releasingthe comprehensive May 2016 reportthat found no evidence that foods derived from genetically engineered (GE) crops were unsafe to eat, noted that it is clear that the proportion of Americans who believe that foods derived from GE crops pose a serious health hazard to consumers has steadily increased, from 27 percent in 1999 to 48 percent in 2013.

This trend pits those who are skeptical of genetic engineering against those who, alongside agencies like the Food and Drug Administration, Environmental Protection Agency, U.S. Department of Agriculture and National Academy of Sciences, believe that genetic engineering is not only safe but has the potential to be a powerful tool for food production in the future.

Simply speaking, genetic engineering is a process whereby genes can be moved within a species or from one species to another, saysJack Britt, an Asheville-based scientist, consultant and agricultural professor of nearly 40 years at institutions like N.C. State University and the University of Tennessee. All of us have genes or pieces of genes that came from other species. Some have been introduced by viruses and bacteria, and some have been spread by biting insects and the organisms they inject into us when they bite.In the 1960s, scientists discovered how to excise and insert DNA (genes). The methods used by scientists are the same as those used by bacteria and viruses to move genes around among species, except that scientists do this more precisely than bacteria and viruses.

Essentially, the idea is that genetic engineering is simply a more efficient means of doing something that nature has always been doing since the dawn of time improving species through natural selection. We now know that nature has created many GMO crops over millions of years. The same organism that is used by scientists to move genes into corn, soybeans, papaya, canola, alfalfa and other GMO crops has been moving genes across species naturally for a long time. When the sweet potato genome was sequenced a few years ago, it was discovered that it was a true GMO crop and that the same organism has left its footprint in the sweet potato thousands of years ago.

WHAT GMO Free NC hosts the sixth annual March Against Monsanto. The march is kid- and pet-friendly. Participants are encouraged to wear earthy colors and/or creative costumes.

WHERE Downtown, starting and ending atthe Vance Monument

WHENSaturday, May 20 Rally begins at 11 a.m., march begins at noon. Rain or shine.

DETAILS Visit the events Facebook page at avl.mx/3pv for updates, including informationabout a sign-making circle planned for 4 p.m. Thursday, May 18, at The Block Off Biltmore.

Rather than improving species through whats essentially rolling the dice, genetically speaking, genetic engineering is much more targeted. With GMOs, there may be one gene altered. Yourenot changing a host of genes. Its very deliberate and very direct. Its not like taking a Schnauzer and breeding it with a St. Bernard and seeing what were going to get, saysLeah McGrath, corporate supermarket dietitian for Ingles Markets.

The use of GMOs and genetic engineering is also more prevalent than many people realize. Insulin is a GMO, so everyone who is a Type 1 diabetic relies on a product of genetic engineering, says McGrath.

Genetic engineering is used widely in processing and manufacturing of thousands of products that we all use every day, says Britt. Many cosmetic, health and other products are produced in fermentation vats using genetically modified E. coli.The technology that is used to produce GMO crops is used to make hundreds of products such as cold-water detergents, bread preservatives, many over-the-counter products and many pharmaceuticals.

Despite the widespread use of GMO-based products, many of the foods grown today fall outside the realm of what is considered genetically modified. Remember that there are no tomatoes, cucumbers, lettuces, kale, collards andmany other vegetables that are genetically engineered, saysFred Gould, N.C. State professor and chair of the National Academy of Sciences committee on GE crops. So unless your farm is focused on commodity row crops, you probably dont even have access to engineered crops.

The current list of GE foods on the market includes corn, soybeans, cotton, Innate Potatoes, papaya,squash, canola, alfalfa, arctic apples, sugar beets and AquaBounty salmon, according to a report frombestfoodfacts.org.

The number of GMO crops out on the market is limited by the regulatory process theyre subjected to.It can actually take almost 20 years to bring a GMO product to market. There are trials upon trials beforethat can happen, says McGrath. Britt agrees, noting that GMO crops are under much more control by FDA, EPA and USDA than any other farm products.

McGrath says its important for consumers to understand which GMO foods are in circulation so theres no risk of being exploited by unfounded, fear-based marketing. When you have small grocery stores, even here in Asheville, that put out adsshowing a tomato or strawberry with a syringe in it, implying that those products are GM, its important to understand that there arent actually any GMO strawberries or tomatoeson the market, says McGrath.

Despite the fact that every national scientific and medical agency in the world has declared that GMO foods are safe, according to Britt, many people are still concerned and skeptical.

According to a recentvideo released byKurzgesagtvia YouTube, there are several common objections to genetic engineering, including gene flow (the concept that GM crops can mix with traditional crops and introduce unwanted new traits into them), the use of terminator seeds (which are essentially seeds that produce sterile plants, requiring farmers to buy new seeds every year) and the use of chemical pesticides and herbicides, like the weed-killing herbicide glyphosate.

The use of pesticides and herbicides especially causes alarm among vocal critics in Asheville.

Philosophically and ethically, I believe that you are what you eat, and I do my best to source and cook ingredients that are local, sustainable and healthy. For me, the conversation about GE and healthy eating is the use of herbicides and pesticides in our food, says Dissen.

Agricultural communities suffer the greatest and most obvious effects of the ever-increasing amount of poison being sprayed, saysChris Smith, community coordinator at Asheville-basedSow True Seed. Glyphosate is showing up in groundwater. Studies show effects on beneficial insects and pollinators, not least because of the killing off of plants like milkweed, the preferred food of monarch butterflies. More emerging studies are linking health issues to people who get drift from aerial spraying. And that isnt to mention the real threat to the biodiversity of food and other crops in nearby fields, says Smith.

AnneandAaron Grierrun the 70-acreGaining Ground Farm in Leicester and have been selling vegetables in Asheville since 1999. We currently grow 14acres of vegetables on land that we lease from immediate family. We do actively avoid GMO seed in our vegetable production. We actively avoid buying non-GMO seed from companies that also produce and sell GMO seeds. We worry about GMOs unintended impacts on insects and increased usage of herbicide in Roundup Ready-type applications, say the Griers.

Britt seemsless concerned than Dissen, Smith and the Griers about the use of chemicals like glyphosate. The primary advantage of GMO corn and other GMO crops is that they simplify control of weeds and control of insect damage to crops, says Britt. In general, weeds are now typically controlled by a single herbicide (glyphosate) rather than multiple herbicides, and the GMO plants often include a BT toxin that kills insects that feed on plants.

When Britt refers to weeds controlled by glyphosate, he is referring togenetically modified herbicide-resistant crops (think Roundup Ready), which have been engineered to survive exposure to glyphosate, the chemical (found in Roundup spray)known to kill weeds. The BT that Britt references is a gene borrowed from the bacterium Bacillus thuringiensis, which allows engineered plants to produce a protein that destroys the digestive systems of specified insect pests. So basically, the plant makes its own pesticide, and insects that eat it will die.

Butare BT toxins bredinto crops something to worry about? Unlike many pesticides, the BT toxin is not active in humans. The bacteria that produces the BT toxin is used by organic farmers to control pests in their organic crops. It is a natural product, says Britt.

Britt counters concerns about the overall use of pesticidesby noting that now we spray much less than previously, and pesticide use in the U.S. has declined significantly over the last two decades. According to worldwide statistics, the U.S. now ranks around 43rd in the world in amount of pesticide used per acre of arable farmland. Fertilizer use has also declined, and we rank about 62nd in the world in fertilizer use per acre.

For Gould, some objections to the current use of GE technology may be valid, but not those regarding the health or safety for humans and the environment. The overall data doesnt show that GMOs themselves cause human and environmental safety problems, says Gould. If you are against GMOs for ethical and societal reasons, I think its best to express your opposition in those terms instead of health and environmental terms.

Laura Lengnick, professor of sustainable agriculture at Warren Wilson College and author of the bookResilient Agriculture, says: GE technology may be a useful tool in climate change adaptation, but not as it is used today. In general, GE technology is a great example of the overemphasis on technological solutions to food production challenges that characterizes industrial agricultural.

Britt disagrees.The first GMO on the market was Roundup-resistant corn, and that was really designed so that Monsanto could sell more Roundup. Now, while it definitely makes planting and growing corn simpler for the farmer, the company was primarilyfocused on selling more Roundup. So, ultimately, that was a product that made a lot of money for [Monsanto], farmers liked it, but itwasnt necessarily a great step forward in terms of producing food more efficiently or meeting needs any better, except for maybe reducing the overall use of pesticides, says Britt.

For Anne and Aaron Grier of Gaining Ground Farm, everyday shoppers carry a responsibility when it comes to farmers buying seed from companies like Monsanto.We think that most of the responsibility rests with the consumer making decisions with their dollar. If consumers quit buying products that contained GMO crops, farmers would quit using GMO seeds, say the Griers.

Companies like Monsanto are for-profit corporations with shareholders and board members to satisfy. Thus, consumer and agricultural concerns may be secondary to generating profits. This isnt to imply that these companies are malicious or nefarious, however,but rather a reminder that profits are a top priority for many companies. Which company does not have an intention tomake profit? Britt asks.

Britt says the GMO technologies were using today arent particularly enhancing the state of agriculture, as they have the potential to, but believes there is reason to be optimistic about the future of GE. I think the long-term advantages of genetic engineering or gene editing is for things like drought resistance and salt tolerance, he says. Could you grow plants in salty water? If we could do that, we wouldnt have to worry about irrigation water.

Britt also believes GMOs may soon be a thing of the past. My guess is that GMO will soon be replaced by gene-editing, he says. Its quicker, easier to do and has a precision that is exceptionally high. With gene-editing, a specific gene is excised or cut from the DNA, and its replacement is inserted in the space that was cut out. Often the replaced gene is a slightly different version of the one that was cut out and often leads to improved health or some other benefit to the plant or animal.

With growing concerns around global population growth and impending climate change, there is certainly reason to move forward with research and development of potentially effective GE technologies. I dont think you can draw a line in the sand and just say no to GE, says McGrath. I think we have to realize that we need tohave these tools in our toolbox and dont have the luxury of taking anything off the plate.

Those critical of GE maintain that we need to proceed with caution, however. Could publicly funded altruistic application of certain types of biotech help us in the future? Smith asks. Quite possibly. Will biotech be a golden wand that solves all our problems? Extremely unlikely. We need big system changes, which means human behavior needs to change and that relies on the most complex tool we have at our disposal: our brains.

Turns Out Nazis Have Some Pretty Wrong Views About Genetics – New York Magazine

Posted: at 1:55 pm

Photo: Stefano Bianchetti/Getty Images

Most people tend to have a certain idea about their heritage: that they simply are, well, whatever they are. Scottish or German or Nigerian or whatever else. Maybe theres some other stuff mixed in there, sure, but most people have a sense that theyre from one particular place, and thats where their culture and maybe some of their values originates.

Naturally, DNA tells a more complicated story, and a new article in Science by Ann Gibbons very usefully punctures a bunch of myths, some of them pretty harmful, about human ancestry. The vast majority of us are mutts, it turns out, and oftentimes the genetic heritage we think we have bears little resemblance to whats actually hiding in our chromosomes.

Gibbons starts the article by quoting a German neo-Nazi, doing what neo-Nazis tend to do, expressing alarm about the arrival of Syrian refugees and the prospect of them sullying his precious German genetic heritage.

From there she swiftly moves to the main point of the article:

Using revolutionary new methods to analyze DNA and the isotopes found in bones and teeth, scientists are exposing the tangled roots of peoples around the world, as varied as Germans, ancient Philistines, and Kashmiris. Few of us are actually the direct descendants of the ancient skeletons found in our backyards or historic homelands. Only a handful of groups today, such as Australian Aborigines, have deep bloodlines untainted by mixing with immigrants.

That aforementioned notion of German purity, to take one example, comes from a Nazi mangling of an already somewhat thinly sourced story about a Germanic fighter named Arminius who supposedly led a rebellion against the Romans 2,000 years ago the Nazis portrayed him as a blond-haired member of a supposed master race.

Now, it shouldnt be surprising that Nazis dont have a particularly sophisticated grip on genetics. But this article is still an interesting, comprehensive look at where researchers are in their quest to understand humanitys genetic legacy. And the short, also-unsurprising answer is: Weve moved around a lot and mixed it up a lot.

Gibbonss piece also usefully complicates the notion of genetic superiority, highlighting just how historically contingent this idea is. For example, she writes of two different groups that collided at one point and produced offspring: The unions between the Yamnaya and the descendants of Anatolian farmers catalyzed the creation of the famous Corded Ware culture, known for its distinctive pottery impressed with cordlike patterns According to DNA analysis, those people may have inherited Yamnaya genes that made them taller; they may also have had a then-rare mutation that enabled them to digest lactose in milk, which quickly spread It was a winning combination. The Corded Ware people had many offspring who spread rapidly across Europe. Today, of course, very few people are aware of the Corded Ware culture a group that was very much, for random genetic reasons, in the right place at the right time.

For most of human history, humans havent been great at recording history accurately, so along the way many cultures have developed myths about their lineage, about who was where, when. A lot of the time, the straightforward stories people tell to be proud of themselves and their ancestors are oversimplifications, at best. In the worst cases, these myths lead to ideologies like nationalism.

Its important to understand the appeal and functional role of bloodline myths, of course: This group could sully our bloodlines packs a bit more of a visceral punch than I am nervous this new group will cause the neighborhood to change. Because people dont tend to really understand genetics, and because the subject efficiently taps into many peoples most intimate feelings about disgust and purity, such talk can be a useful way to rile people up, almost always for the worse. Which is why its important to understand just how superficial it really is.

A new study found that when you pair two disagreeable people together, they both get what they want and have more fun in the process.

A new study looks at the sales of an at-home HIV-testing kit and finds some very encouraging results.

The psychology of how we choose who to leave out.

Research suggests that sexism in hiring cant explain the entire gender gap in leadership positions theres other stuff going on, too.

Just about everyone, everywhere, is a complicated mutt, and stories about pure bloodlines are almost always false.

Labels like organic and natural are impossibly vague and often misleading.

Most adults can do a decent job of understanding other peoples internal mental states. Not the leader of the free world.

Or its about to be, at least. Thats just the life cycle of any fad.

It might seem counterintuitive to advertise a place for injection-drug users to shoot up, but theres smart public-health reasoning behind the idea.

Not exactly, but theres some merit to the myth.

Time to find another hangover remedy.

A realization about monogamy that should make anyone getting married feel a little more hopeful.

Its a mixed bag.

The science behind a common-sense piece of advice.

Giving your mind time to wander is a key part of creativity.

Theres a bit of dissent within the American Psychological Association about the role of video games in contributing to violence.

A new TEDx video sums up the research of Bella DePaulo, a social psychologist who has been chipping away at the many myths surrounding marriage.

No matter how long they live in a loud urban environment.

The WHO and the CDC offer different recommendations for proper handwashing technique. Which is right?

DNA Breakthrough: Using DNA snapshots to reveal cold case killers – CBS 8 San Diego

Posted: at 1:53 pm

SAN DIEGO (NEWS 8) - In 2007, 39-year-old Jodine Serrin was living alone in her Carlsbad condo when she was raped and strangled. Ten years later a snapshot of what her killer could look like has been released.

Investigator Tony Johnson works cold cases withthe San Diego County District Attorney's office.

"It is very important to resolve these cases because somewhere out there is a family. We have DNA, but the DNA has no hit in the database," he said.

Johnson and Carlsbad police have not given up on solving Serrin's murder, but the case has hit a dead-end.

On the ten year anniversary of Serrin's murder, CBS News 8 reported investigators announced they would use a new tool called DNA Phenotypingto help catch the killer.

Johnson called it "a game changer."

Parabon Nanolabs, based in Virginia, is one of the first of its kind. Researchers have produced several snapshots of suspects based on one nanogram of DNA.

In Costa Mesa, a killer was identified. In North Carolina, a murderer pleaded guilty.

Dr. Ellen Greytak, director of Bioinformatics at Parabon, explained the sophisticated software has only been available for two-and-a-half years.

The software sifts through tens of thousands of genetic variants to simulate a face based on hair, skin, eye color, freckles, ancestry and quantifying faces with levels of confidence.

"The goal is exclusion. Phenotyping treats DNA like it's a blueprint and it contains all of the information of that person and actually uses that DNA to generate leads and narrow a suspect list," said Dr. Greytak.

The snapshot creates what the suspect would look like at age 25 and average weight.

Critics, however, argue this could encourage profiling.

"This is not for identification. The goal is not to produce a composite that look like only one person in the world," said Dr. Greytak.

Investigators said that since the snapshot was released in February, they have received confidential leads in Serrin's case - giving her family hope.

"I can walk now to her grave and say, 'Jodine, I'm still trying'" said Jodine's father.

In Jodine Serrin's case, investigators said the DNA Phenotyping cost them $7,000.

While the technology may not be admissible in court, District Attorney investigators said just like a tip they receive, it can be a lead or a guide for them in a case.

There is a $52,000 reward in the Jodine Serrincold casemurder. If you know anything or anyone who may resemble this man, call Carlsbad Police.
