I’m a climate scientist. And I’m not letting trickle-down ignorance win. – Washington Post

Posted: July 5, 2017 at 8:41 am

By Ben Santer By Ben Santer July 5 at 6:00 AM

Ben Santer is a climate scientist and a member of the National Academy of Sciences.

Ive been a mountaineer for most of my life. Mountains are in my blood. In my early 20s, while climbing in France, I fell in a crevasse on the Milieu Glacier, at the start of the normal route on the Aiguille dArgentire. Remarkably, I was unhurt. From the grip of the banded ice, I saw a thin slit of blue sky 120 feet above me. The math was simple: Climb 120 feet. If I reached that slit of blue sky, I would live. If I didnt, Id freeze to death in the cold and dark.

Now, over 40 years later, it feels like Im back in a different kind of darkness the darkness of the Trump administrations scientific ignorance. This is just as real as the darkness of the Milieu Glaciers interior, and just as life-threatening. This time, Im not alone. The consequences of this ignorance affect every person on the planet.

Imagine, if you will, that you spend your entire professional life trying to do one thing to the best of your ability. In my case, that one thing is to study the nature and causes of climate change. You put in a long apprenticeship. You spend years learning about the climate system, computer models of climate and climate observations. You start filling a tool kit with the statistical and mathematical methods youll need for analyzing complex data sets. You are taught how electrical engineers detect signals embedded in noisy data. You apply those engineering insights to the detection of a human-caused warming signal buried in the natural noise of Earths climate. Eventually, you learn that human activities are warming Earths surface, and you publish this finding in peer-reviewed literature.

You participate in rigorous national and international assessments of climate science. You try to put aside all personal filters, to be objective, to accommodate a diversity of scientific opinions held by your peers, by industry stakeholders and by governments. These assessments are like nothing youve ever done before: They are peer review on steroids, eating up years of your life.

The bottom-line finding of the assessments is cautious at first. In 1995, the conclusion is this: The balance of evidence suggests a discernible human influence on global climate. These 12 words are part of a chapter on which you are first author. The 12 words change your life. You spend years defending the discernible human influence conclusion. You encounter valid scientific criticism. You also encounter nonscientific criticism from powerful forces of unreason, who harbor no personal animus toward you, but dont like what youve learned and published its bad for their business.

[I worked on the EPAs climate change website. Removing it is a declaration of war.]

You go back to the drawing board. You address the criticism that if there really is a human-caused signal, we should see it in many attributes of the climate system not just in surface thermometer records. You look at temperature from the top of the atmosphere to the depths of the oceans. You examine water vapor and the height of the lowest layer of the atmosphere. Your colleagues search for human fingerprints in rainfall, clouds, sea level, river runoff, snow and ice extent, atmospheric circulation patterns and the behavior of extreme events. You find human-caused climate fingerprints everywhere you look.

Your peers are your fiercest critics. They are constantly kicking the tires. Show us that your discernible human influence results arent due to changes in the Sun, or volcanic activity, or internal cycles in the climate system. Show us that your results arent due to some combination of these natural factors. Convince us that detection of a human fingerprint isnt sensitive to uncertainties in models, data or the statistical methods in your tool kit. Explain the causes of each and every wiggle in temperature records. Respond to every claim contradicting your findings.

So you jump through hoops. You do due diligence. You go down every blind alley, every rabbit hole. Over time, the evidence for a discernible human influence on global climate becomes overwhelming. The evidence is internally and physically consistent. Its in climate measurements made from the ground, from weather balloons, and from space measurements of dozens of different climate variables made by hundreds of different research groups around the world. You write more papers, examine more uncertainties, and participate in more scientific assessments. You tell others what youve done, what youve learned, and what the climatic shape of things to come might look like if we do nothing to reduce emissions of heat-trapping greenhouse gases. You speak not only to your scientific peers, but also a wide variety of audiences, some of whom are skeptical about you and everything you do. You enter the public arena, and make yourself accountable.

After decades of seeking to advance scientific understanding, reality suddenly shifts, and you are back in the cold darkness of ignorance. The ignorance starts with President Trump. It starts with untruths and alternative facts. The untruth that climate change is a hoax engineered by the Chinese. The alternative fact that nobody really knows the causes of climate change. These untruths and alternative facts are repeated again and again. They serve as talking points for other members of the administration. From the Environment Protection Agency administrator, who has spent his career fighting against climate change science, we learn the alternative fact that satellite data show leveling off of warming over the past two decades. The energy secretary tells us the fairy tale that climate change is due to ocean waters, and this environment in which we live. Ignorance trickles down from the president to members of his administration, eventually filtering into the publics consciousness.

[Why Im trying to preserve federal climate data before Trump takes office]

Getting out of this metaphorical darkness is going to be tough. The administration is powerful. It has access to media megaphones and to bully pulpits. It can abrogate international climate agreements. It can weaken national legislation designed to protect our air and water. It can challenge climate science and can tell us that more than three decades of scientific understanding and rigorous assessments are all worthless. It can question the integrity and motives of climate scientists. It can halt satellite missions and impair our ability to monitor Earths climate from space. It can shut down websites hosting real facts on the science of climate change. It can deny, delay, defund, distort, dismantle. It can fiddle while the planet burns.

I have to believe that even in this darkness, though, there is still a thin slit of blue sky. My optimism comes from a gut-level belief in the decency and intelligence of the people of this country. Most Americans have an investment in the future in our children and grandchildren, and in the planet that is our only home. Most Americans care about these investments in the future; we want to protect them from harm. That is our prime directive. Most of us understand that to fulfill this directive, we cant ignore the reality of a warming planet, rising seas, retreating snow and ice, and changes in the severity and frequency of droughts and floods. We cant ignore the reality that human actions are part of the climate-change problem, and that human actions must be part of the solution to this problem. Ignoring reality is not a viable survival strategy.

Trump has referred to a dark cloud hanging over his administration. The primary cloud I see is the self-created cloud of willful ignorance on the science of climate change. That cloud is a clear and present threat to the lives, livelihoods and health of every person on the planet, now and in the future. This cloud could be easily lifted by the president himself.

But for my own part, I dont intend to spend the rest of my life in darkness or silently accepting trickle-down ignorance. I didnt climb out of a crevasse on the Milieu Glacier for that.

Total Solar Eclipses Are on the Path to Extinction – Futurism

Posted: at 8:41 am

In Brief Due to the Earth's rotation being slowed by tidal movement, the Moon is moving further away, which means that the days of total solar eclipses are numbered. This makes catching the event in August even more important. Elusive Eclipse

Solar eclipses have been vital to humanitys study of the Sun and the workings of our solar system. But over the course of future millennia this phenomenon will change forever.

Due to the Moon moving away from the Earth at a rate of 3.8 cm (1.5 inches) a year, total solar eclipses will decrease in frequency and annular eclipses, during which the Suns ring of fire remains visible, will increase in frequency. Although humans probably wont be on Earth when the last total eclipse occurs in 620 million years because well probably be living on Mars, where annular eclipses occur almost daily the inevitable cut-off date may make it slightly more pressing for you see them while they still happen.

The discovery of the lengthening time between solar eclipses began with Edmond Halley in 1695, who realized that according to the contemporary dates that eclipses were on, eclipses in ancient Greece and Rome were occurring on the wrong days. Due to his faith in Isaac Newtons principle of general gravitation, he concluded that days on Earth must be getting longer because the planets rotation was slowing.

Halleys hypothesis was later definitively proven by using the laser measuring instruments that the Apollo astronauts left on the Moon. Scientists discovered that tides are responsible for the rotation slowing. The cumulative effect of shallow waters around a land mass (continental shelves) colliding with high tides create a force that slows the rotation.

As the rotation slows, the Moon gains angular momentum to preserve equilibrium in the Earth-Moon system. As it gains more momentum, it moves further away. Eventually, this means that it will be too far away to obscure all of the Sun meaning total eclipses can no longer occur.

The next solar eclipse is on August 21st, and is remarkable because it is the first eclipse that will be visible the U.S. since 1979. As solar eclipses will become more and more infrequent, its important to try to witness the cosmic intricacy while you still can.

Our understanding of the relationship between the Earths rotation, the Moons position, and solar eclipses is an example of generations of scientists building on discoveries that proceeding them and working towards truth in a collaboration across time. Due to the nature of space in which things happen slowly it is only through long-term study that we can come to know universal details and occurrences like these.

There are several projects and missions underway currently that will probably also need this multi-generational approach to understand all the ramifications of their discoveries. An example is the multiple Mars missions. While the NASA project Mars Atmosphere and Volatile Evolution (MAVEN) has shown us that Mars atmosphere was robbed by solar winds and the Suns energy, it is only through observation over multiple lifetimes that we will understand the precise nature of these phenomena.

Despite our years of research, our solar system and the star at the heart of it continue to baffle and amaze us. Even as we move closer to our goal of touching the Sun, we can rest assured that our perspective of it will continue to change even millions of years into the future.

The Futurist: Innovation challenges for HR – Human Resources Online

Posted: at 8:40 am

HR has the opportunity and responsibility to hire capable, diverse people with ideas and the capacity to think out of the box, says Lelia Konyn, head of human resources and corporate affairs at Shun Shing Group.

Companies increasingly call for innovation to stimulate growth, update business models, increase performance and appeal to customers.

The logic is simple: companies need to innovate to stay current, compete and create value and many are grappling with the realisation that what got us here will not take us forward. Hence, the need to engage employees and create processes conducive to business innovation overall.

Enter HR. As the custodian of people strategy and processes, HR has a tremendous opportunity to hire capable, diverse people with ideas and the capacity to think out of the box. HR is also the custodian of organisation design, and is often put in charge of corporate culture. People, organisation and culture is all it takes to foster innovation.

So why isnt there more innovation about? Because the very aspects that offer HR tremendous opportunities offer significant challenges:

Integration means embracing the company culture and the way things are done. Fitting in. Divergent ideas challenging the status quo are suppressed or watered down. The comfort of groupthink sets in.

Most companies are systemically not built to facilitate, sustain or nurture innovation. Few are the hierarchies in which bosses ideas, decisions or processes can be questioned and debated openly and consistently as a process.

Matrix organisations increase complexity: numerous functions, business units and locations often operate in silos with poor co-ordination, information flow and slow decision-making.

Corporate culture defines the acceptable way to act and work within an organisation. Complacency, lack of process to speak up and debate, fear of making mistakes in a blame culture, change aversion, endless emails and meetings are not conducive to innovation.

So what can HR do?

Fourth of July in Space: How Will the Astronauts Celebrate? – Space.com

Posted: July 4, 2017 at 7:52 am

NASA astronauts Peggy Whitson and Jack Fischer will celebrate the Fourth of July on the International Space Station.

Today (July 4), people all across the U.S. will celebrate Independence Day with cookouts, flags and fireworks. On the International Space Station, things will be a bit more subdued.

NASA astronauts Peggy Whitson and Jack Fischer will be celebrating the national holiday on the orbiting outpost, although they will not take the day off due to some scheduled science operations, a NASA representative told Space.com via email. In lieu of a July Fourth vacation, the crew members took yesterday (July 3) off, the representative said right after they released a Dragon cargo spacecraft from the station early that morning.

There are also no barbecue grills or fireworks in space (because there can be no open flames), but Whitson and Fischer did bring along some patriotic clothing to wear today, the representative said. [Holidays in Space: An Astronaut Photo Album]

At the moment, there are no plans for a special meal on the station, but that could change at the discretion of the astronauts, the representative said. And unfortunately, fireworks displays taking place on Earth are too dim to be visible from the orbiting laboratory, the representative said. (However, some NASA astronauts have said they were able to spot fireworks from the station).

This is Whitson's second July Fourth in space. On June 5, 2002, during her first space mission as a NASA astronaut, she flew to the station aboard the Space Shuttle Endeavor, as part of STS-111. On the station she joined the crew of Expedition 5. Whitson recently broke the record for most cumulative time spent in space by a NASA astronaut. She and Fischer are both scheduled to return to Earth in September.

Study finds 1317 knocked-out genes in DNA samples from Pakistanis – DAWN.com

Posted: at 7:51 am

Research published in the journal Nature has analysed the DNA of 10,503 Pakistanis who were participating in a Pakistan Risk of Myocardial Infarction Study (PROMIS) and discovered 1,317 disabled or knocked-out genes.

People who are natural knockouts, that is, they were born missing one or more genes without any obvious medical problems are few and far between.

Humans inherit two copies of every gene one from the mother and one from the father.

If one copy is damaged or inactivated, then the presence of the other fully functional copy may help alleviate most problems.

However, if the parents are biologically related, then the chances of inheriting two inactivated copies are much higher.

The person with two inactivated copies may not have the functioning protein at all and will be a natural knockout for that specific gene.

The high number of human knockouts found in the country is due to the cultural tradition of cousin marriages that is prevalent here.

A search for human knockouts has also been conducted in other countries including Iceland and the United Kingdom.

In order to study what a particular gene does, scientists have traditionally made use of genetic engineering to breed mice with a mutation in that gene (as this type of experimentation is not possible with humans).

Once they have discovered what the gene does, it is possible to make new drugs that can either block a gene if it is harmful or enhance its positive functions if it turns out to be useful.

However, while such research is informative, evidence from studies in animal knockouts often does not hold for humans.

This is explained by a substantial number of failures seen in recent clinical trials that tested new drugs for the prevention of coronary heart disease.

Read more: The Tech Healthcare Revolution Pakistan Needs

Studies in human knockouts can provide data regarding whether natural inhibition of a given pathway is useful or not, says Dr. Danish Saleheen, lead author and principal investigator of the study published in Nature.

This evidence could be translated to develop new drugs, and prioritise or deprioritise existing drug programs.

Some knocked-out genes protect against disease.

Absence of the gene ALOX5 protects against stress-induced memory deficits, synaptic dysfunction and tauopathy which can help prevent Alzheimers disease or lower its progression.

The discovery of a human PCSK9 knockout who had astonishingly low levels of LDL cholesterol and up to 90 per cent less chances of getting a heart attack has resulted in the development of a new class of drugs that could prevent heart disease.

The Nature research study discovered that individuals without the gene APOC3 were protected against coronary heart disease.

The protein Apo-CIII is encoded by the APOC3 gene and inhibits hepatic uptake of fats called triglycerides.

The team was able to study a family of Pakistanis missing both copies of the APOC3 gene.

The human knockouts were given an oral fat load in the form of a milkshake.

When compared to other family members who had the gene, individuals with an absence of APOC3 didnt get a significant postprandial rise in their blood fat levels and were perfectly healthy.

This showed the human knockouts had little artery-clogging fat in their body and had a considerably lower risk of getting a heart attack.

So the research team was able to reason that ApoC-IIIblocking drugs that are currently in clinical trials could be beneficial in preventing heart disease.

The team was only able to make this discovery after identifying an entire family of natural knockouts for APOC3 in Pakistan.

They had been searching for the past four years for someone who was missing both copies of the gene but hadnt found a single person in the United States and Europe.

It was only in Pakistan that they were able to discover a family with both parents and nine children all of whom were missing the gene.

Read more: Is a permanent cure for diabetes on the cards?

This Pakistani research study is reportedly the first time where the knockouts found have been tested and their blood biomarkers like cholesterol have been studied to discover more about their health.

As part of this study, knockouts have been found that have not been seen anywhere else in the world.

This includes knockouts for NRG4, A3GALT2 and CYP2F1 among others.

In addition, the study found 734 genes where both copies were affected by predicted loss-of-function mutations (double knock-outs) which had never been described before.

This cohort of individuals provides a great opportunity for further study and more extensive phenotyping, says Dr. James Peters, Clinical Research Fellow at the British Heart Foundation.

A particular strength of this study is that individuals with a specific mutation can be contacted and brought back for further detailed measurements, he adds.

However, some geneticists caution that drugs made from this kind of genetic analysis might not be effective.

In an article, geneticist Stephen Rich from the University of Virginia in Charlottesville says that inhibiting ApoC-III late in life may not mimic being born with an APOC3 mutation, which protects for a lifetime.

The research team is now calling for a human knockout project to make one complete database for all the information coming from new genetics studies.

The project would make it possible to systematically conduct deep phenotyping studies on human knockouts and learn more about the natural deletion of those genes in humans.

In the future, the team plans on testing the genomes of 200,000 participants from Pakistan to find knockouts of approximately 8,000 genes.

Such studies provide unprecedented opportunities to understand the function of genes and provide important insights into the development of drugs, says Dr. Saleheen.

This research study was the result of an international collaboration between scientists from Pakistan, the United Kingdom and the United States.

Dispute Over British Baby’s Fate Draws In Pope and US President – New York Times

Posted: at 7:50 am

Three courts in Britain agreed with the hospital, as did the European Court of Human Rights, which last week rejected a last-ditch appeal by Charlies parents.

But Pope Francis and Mr. Trump have also weighed in, adding another dimension to an extraordinarily thorny bioethical and legal dispute that pits Britains medical and judicial establishment against the wishes of the childs parents.

Judges in the case have acknowledged that the case highlights differences in law and medicine and an American willingness to try anything, however unlikely the possibility of success but have held that prolonging the infants life would be inhumane and unreasonable. The case echoes the one of Terri Schiavo, a Florida woman who was left in a persistent vegetative state after a cardiac arrest and was also the subject of a court battle.

A Vatican spokesman, Greg Burke, told Vatican Radio on Sunday that the pope had been following the parents case with affection and sadness, praying that their desire to accompany and care for their own child to the end is not ignored.

Italys top pediatric hospital, which is run by the Vatican, told the Italian news agency ANSA on Monday that it would be willing to take Charlie.

We understand that the situation is desperate, said Mariella Enoc, director of the Bambino Ges hospital in Rome, noting that she had been in touch with British officials to signal a willingness to take the patient, the agency reported. We are close to the parents in prayer and, if this is their desire, we are open to receiving their child at our structure for the time it will take for him to live.

Mr. Trump, who was not known to have previously expressed a view on the matter, wrote on Twitter on Monday that if the United States could help, we would be delighted to do so.

Both the pope and the president stopped short of criticizing the court rulings or the hospital. Helen Aguirre Ferr, the director of the White House office of media affairs, said Mr. Trump had decided to speak out after he learned about this heartbreaking situation. Mr. Trump has not spoken with the family, she said, and does not want to pressure them in any way.

The president is just trying to be helpful if at all possible, she added.

Charlie was born on Aug. 4 with encephalomyopathic mitochondrial DNA depletion syndrome. He is thought to be one of only 16 children globally with the condition, the result of a genetic mutation.

Brendan Lee, the chairman of the department of molecular and human genetics at Baylor College of Medicine, who is not involved in the case, said in a phone interview that mitochondrial depletion syndrome has no cure. Treatments involve different types of vitamin supplementation, but none have been shown to definitively work through studies, he said.

Charlies parents, Connie Yates and Chris Gard, both in their 30s, have been waging a long and wrenching legal battle to keep him alive. They have raised more than 1.3 million pounds, or about $1.7 million, to help finance experimental treatment in the United States. There is also an international campaign, with an online petition, and there have been street protests in front of Buckingham Palace.

Charlie has been treated since October at Great Ormond Street Hospital, where doctors eventually decided that withdrawing life support was the only justifiable option. Although Charlies parents have parental responsibility, overriding control is by law vested in the court exercising its independent and objective judgment in the childs best interests, the hospital said in a statement laying out its position.

Siding with the hospital were the High Court, on April 11; the Court of Appeal, on May 25; and the Supreme Court of the United Kingdom, on June 8.

The High Court ruled that Charlie would face significant harm if his suffering were to be prolonged without any realistic prospect of improvement. Moreover, it said the experimental treatment, known as nucleoside therapy, would not be effective.

Money is not at issue; an academic medical center in the United States has offered to provide the experimental treatment. But a neurologist at the hospital, who has offered to oversee the treatment, told the court by telephone: I can understand the opinion that he is so severely affected by encephalopathy that any attempt at therapy would be futile. I agree that it is very unlikely that he will improve with that therapy.

Neither the hospital nor the neurologist was identified in court documents, and the White House has declined to identify either.

The Court of Human Rights ruled last week that the British courts had acted appropriately in concluding that it was most likely Charlie was being exposed to continued pain, suffering and distress, and that undergoing experimental treatment with no prospects of success would offer no benefit, and continue to cause him significant harm.

The case has drawn attention to important differences in legal systems.

Claire Fenton-Glynn, a legal scholar at the University of Cambridge who studies childrens rights, said that under British law, the courts were the final arbiter in medical disputes about the treatment of children.

She noted a 2001 case of conjoined twins, Jodie and Mary, who were born sharing an aorta. Separating the twins would lead to the death of the weaker twin; if they were not separated, both would die. A court ruled that the twins should be separated against the wishes of their parents; as expected, one died.

Courts in the United States are less inclined to get involved when there are disputes between parents and doctors, said Professor Moreno of the University of Pennsylvania, stressing that it was usually left to doctors, in consultation with parents, to decide on a childs treatment.

He noted the case of Baby Jane Doe, who was born in 1983 with spina bifida and whose parents declined to approve surgery to prolong her life. That case led to a law, signed by President Ronald Reagan, that defined instances in which withholding medical treatment from infants could be considered child abuse, but also provided that in certain cases doctors and parents might choose to withhold treatment from seriously handicapped babies when such action would merely prolong dying.

G. Kevin Donovan, the director of the Pellegrino Center for Clinical Bioethics at Georgetown University Medical Center and a professor of pediatrics, said that in the United States, if parents insisted on continuing life-prolonging treatment against a doctors advice, the child would simply be transferred to another institution willing to comply with the parents wishes.

It doesnt seem to be a supportable position morally or ethically, he said of the stance taken by the hospital in London, adding that what is legal and what is ethical are not always the same.

In the Schiavo case, her husband, who was her legal guardian, wanted to have her feeding tube removed, but her parents disagreed, setting off a seven-year fight that ended in 2005, after courts ruled in the husbands favor. Life support was removed from Ms. Schiavo, who died at 41.

In that case, too, the pope, then John Paul II, and the president, George W. Bush, weighed in. Mr. Bush signed an act of Congress allowing federal courts to intercede in the case. But their interventions did not ultimately affect the outcome.

There was no immediate response to Mr. Trumps statement from Charlies parents, who last week appeared to accept the finality of the courts rulings. Photographs of the couple sleeping with their sick child have circulated on social media recently.

We are really grateful for all the support from the public at this extremely difficult time, Ms. Yates said on Friday. Were making precious memories that we can treasure forever with very heavy hearts. Please respect our privacy while we prepare to say the final goodbye to our son Charlie.

There was also no immediate reaction from the hospital.

In Charlies case we have been discussing for many months how the withdrawal of treatment may work, the hospital said. There would be no rush for any action to be taken immediately. It added that it would consult the family and that discussions and planning in these situations usually take some days.

Human Evolution: Africa Exodus Made Homo Sapiens Shorter and Gave Them Arthritis – Newsweek

Posted: at 7:50 am

When the first humans left Africa around 100,000 years ago, they got shorter.

The evolutionary shift helped them cope with the colder conditionsa more compact body size helped protect them from frostbite, whileand shorter limbs would be less breakable when they fellbut it also appears to have come with a downside: arthritis.

In a study published in Nature Genetics on Monday, scientists at Stanford University, California, have shown how variants within the GDF5 gene, which are related to reduced growth, was repeatedly favored by our ancestors as they migrated out of Africa and across the continents.

But GDF5 has also been linked with osteoarthritis,a degenerative joint disease that affects an estimated 27 million Americans. Risk increases with ageit is sometimes referred to as wear and tear arthritisbut it also has a strong genetic component.

Previous research has shown how mutations in part of the GDF5 gene cause malformation in bone structure in mice. In humans, it has been associated with a shortness and joint problems, and two changes in particular are linked with a heightened risk of osteoarthritis.

In the latest research, the scientists find GDF5 provided an evolutionary boost for our ancestors, with arthritis apparently a byproduct of it."The gene we are studying shows strong signatures of positive selection in many human populations," senior author David Kingsley said in a statement

"It's possible that climbing around in cold environments was enough of a risk factor to select for a protective variant even if it brought along an increase likelihood of an age-related disease like arthritis, which typically doesn't develop until late in life."

To better understand GDF5, the team studied the DNA sequences that might affect how the gene is expressedspecifically those that are known as promoters and enhancers. From this they found a previously unidentified region they called GROW1.

When they looked for GROW1 in the 1,000 Genomes Project databasea huge database of genetic sequences of human populations around the worldthe team found a single change that is very common in European and Asian populations, but is hardly ever seen in Africans. The team then introduced this change to mice and found it led to reduced activity in the growth of bones.

They then looked at the change to the genetic variant over the course of human evolution, and found it had been repeatedly favored after Homo sapiens left Africa between 50,000 and 100,000 years ago. The team says the benefits of being shorter in colder conditions probably outweighed the risk of developing osteoarthritis in later life.

Because evolutionary fitness requires successful reproduction, alleles that confer benefits at young or reproductive ages may be positively selected in populations, even if they have some deleterious consequences in post-reproductive ages, they wrote.

Researchers believe this change could help explain why osteoarthritis is rarely seen in Africa, but is more common in other populations.Concluding, Kingsley said: "Because it's been positively selected, this gene variant is present in billions of people. So even though it only increases each person's risk by less than twofold, it's likely responsible for millions of cases of arthritis around the globe.

"This study highlights the intersection between evolution and medicine in really interesting ways, and could help researchers learn more about the molecular causes of arthritis."

July 4, 2017 Genoeconomics looks for genetic ties to life outcomes and economic behavior. Credit: Janice Kun

When Daniel Benjamin was just beginning his PhD program in economics in 2001, he attended a conference with his graduate school advisers. They took in a presentation on neuroeconomics, a nascent field dealing with how the human brain goes about making decisions.

Afterward, as they took a stroll outside, they couldn't stop talking about what they had learned, how novel and intriguing it was. What would be next, they wondered. What would come after neuroeconomics?

"The human genome project had just been completed, and we decided that even more fundamental than the brain would be genes, and that someday this was going to matter a lot for social science," said Benjamin, associate professor (research) of economics at the USC Dornsife College of Letters, Arts and Science's Center for Economic and Social Research (CESR). Indeed, his excitement that day was the foundation of a visionary academic path.

Fast forward to today. Genoeconomics is now an emerging area of social science that incorporates genetic data into the work that economists do. It's based on the idea that a person's particular combination of genes is related to economic behavior and life outcomes such as educational attainment, fertility, obesity and subjective well-being.

"There's this rich new source of data that has only become available recently," said Benjamin, also co-director of the Social Science Genetic Association Consortium, which brings about cooperation among medical researchers, geneticists and social scientists.

Collecting genetic data and creating the large data sets used by economists and other social scientists have become increasingly affordable, and new analytical methods are getting more and more powerful as these data sets continue to grow. The big challenge, he said, is figuring out how scientists can leverage this new data to address a host of important policy questions.

"We're ultimately interested in understanding how genes and environments interact to produce the kinds of outcomes people have in their lives, and then what kinds of policies can help people do better. That is really what economics is aboutand we're trying to use genetics to do even better economics."

The mission at hand

Only a handful of economists are working with genetics, but this brand of research is perfectly at home at CESR. The center, founded three years ago, was conceived as a place where visionary social science could thrive and where research could be done differently than in the past.

"Being in a place where that's the shared vision is pretty rare," said econometrician Arie Kapteyn, professor (research) of economics and CESR director. "There's no restriction on which way you want to go or what you want to do. It doesn't mean that there are no restrictions on resources, but it's the opportunity to think about your vision of what's really exciting in social science research. Then being able to actually implement it is absolutely fantastic."

The mission of CESR is discovering how people around the world live, think, interact, age and make important decisions. The center's researchers are dedicated to innovation and combining their analysis to deepen the understanding of human behavior in a variety of economic and social contexts.

"What we try to do is mold a disciplinary science in a very broad sense," Kapteyn said. "Because today's problems in society, they're really all multidisciplinary."

Case in point: Benjamin's work combining genetics and economics.

The flagship research effort for Benjamin's CESR research group deals with genes and education. In a 2016 study, the team identified variants in 74 genes that are associated with educational attainment. In other words, people who carry more of these variants, on average, complete more years of formal schooling.

Benjamin hopes to use this data in a holistic way to create a predictive tool.

"Rather than just identifying specific genes," he said, "we're also creating methods for combining the information in a person's entire genome into a single variable that can be used to partially predict how much education a person's going to get."

The young field of genoeconomics is still somewhat controversial, and Benjamin is careful to point out that individual genes don't determine behavior or outcome.

"The effect of any individual gene on behavior is extremely small," Benjamin explained, "but the effects of all the genes combined on almost any behavior we're interested in is much more substantial. It's the combined information of many genes that has predictive power, and that can be most useful for social scientists."

Learning about behavior

While the cohort of researchers actively using the available genome-wide data in this way is still somewhat limited, Benjamin says it is growing quickly.

"I think across the social sciences, researchers are seeing the potential for the data, and people are starting to use it in their work and getting excited about it, but right now it's still a small band of us trying to lay the foundations.

"We're putting together huge data sets of hundreds of thousands of peopleapproaching a million people in our ongoing work on educational attainmentbecause you need those really big sample sizes to accurately detect the genetic influences."

As CESR works to improve social welfare by informing and influencing decision-making in the public and private sectors, big data such as Benjamin's is a growing part of that process, according to Kapteyn.

"What big data reflects is the fact that nowadays there are so many other ways in which we can learn about behavior," he said. "As a result, I think we'll see many more breakthroughs and gain a much better understanding of what's going on in the world and in social science than in the past.

"I think we're really at the beginning of something pretty spectacular. What we are doing is really only scratching the surfacethere's so much more that can be done."

Google may get access to genomic patient data here’s why we should be concerned – The Conversation UK

Posted: at 7:50 am

Artificial intelligence is already being put to use in the NHS, with Googles AI firm DeepMind providing technology to help monitor patients. Now I have discovered that DeepMind has met with Genomic England a company set up by the Department of Health to deliver the 100,000 Genomes Project to discuss getting involved.

If this does indeed happen, it could help bring down costs and speed up genetic sequencing potentially helping the science to flourish. But what are the risks of letting a private company have access to sensitive genetic data?

Genomic sequencing has huge potential it could hold the key to improving our understanding of a range of diseases, including cancer, and eventually help find treatments for them. The 100,000 Genomes Project was set up by the government to sequence genomes of 100,000 people. And it wont stop there. A new report from the UKs chief medical officer, Sally Davies, is calling for an expansion of the project.

However, a statement by the Department of Health in response to a freedom of information (FoI) request I made in February reveals this decision has already been made. The department said in this response that the project will be integrated into a single national genomic database. The purpose of this will be to support care and research, and the acceleration of industrial usage. Though it will inevitably exceed the original 100,000 genomes, we do not anticipate that there will be a set target for how many genomes it should contain, the statement reads.

The costs of sequencing the genome on a national scale are prohibitive. The first human genome was sequenced at a cost of US$3bn. However, almost two decades later, Illumina, who are responsible for the sequencing side of the 100,000 Genomes Project, produced the first $1,000 genome a staggering reduction in cost. Applying machine learning to genomics that is, general artificial intelligence has the potential to significantly reduce the costs further. By building a neural network, these algorithms can interpret huge amounts of genetic, health, and environmental data to predict a persons health status, such as their level of risk of heart attack.

DeepMind is already working with the NHS. As part of a partnership with several NHS trusts, the company has built various platforms, an app and a machine learning system to monitor patients in various ways, alerting clinical teams when they are at risk.

But its been controversial. The company announced the first of these collaborations in February 2016, saying it was building an app to help hospital staff monitor patients with kidney disease. However, it later emerged that the agreement went far beyond this, giving DeepMind access to vast amounts of patient data including, in one instance, 1.6m patient records. The Information Commissioners Office ruled recently that the way patient data was shared by the Royal Free NHS Foundation Trust violated UK privacy law.

Googles ambitions to digitise healthcare continue. I received a response to an FoI request in May which reveals that Google and Genomics England have met to discuss using Googles DeepMind among other subjects to analyse genomic data.

Davies insists that data could be anonymised. The Department of Health always promise that medical data used in such initiatives will be anonymised, yet one of the reasons that Care.data (an initiative to store all patient data on a single database) was abandoned is that this was shown to be untrue. I have also shown that the department has misinformed the public about the level of access granted to commercial actors in the 100,000 Genome Project. In particular it said the data would be pseudonymised rather than anonymised, meaning there would still be information available such as age or geographical location.

What would genomic information add to Googles already far-reaching database of individual information? A hint lies in its self-confessed aspiration to organise our lives for us. The algorithms will get better, and we will get better at personalisation, according to Eric Schmidt, executive chairman of Googles parent company Alphabet. This will enable Google users to ask the question, what shall I do tomorrow?, or what job shall I take?.

With personalisation as their ultimate goal, Google intend to use the machine learning algorithms which track our digital footprint and target users with personalised advertising based on their preferences. They also want to analyse health and genomic data to make predictions such as when a person might develop bipolar disorder or tell us what we should do with our lives.

Let us not forget that data, genomic or otherwise, is the oil of the digital era. What is stopping genomic information from being captured, bought and sold? We cannot assume that people will make life choices based upon their genetic profile without undue pressure commercial or governmental.

As for how genomic data might be used and what decisions will be taken about us, the mass surveillance by government agencies of their own citizens is a chilling reminder of the way information technology can be used. There is something unpalatable about everything being connected and everything being known.

When it comes to genetics, the implications are particularly frightening. For example, there is evidence of a link between genes and criminality. We know that 40% of sexual offending risk is down to genetic factors. A single national knowledge base as the one the UK government is aiming to create might therefore be used for broad genetic profiling. Although early intervention programmes that buy into genetically deterministic notions of crime genes are reductive, serious debate about policies involving genetic information will no doubt happen soon.

We can already see the beginnings of this in the United States. The bill Preserving Employee Wellness Programs Act which has received strong backing from Republicans and business groups would allow companies to require employees to undergo genetic testing. The results would be seen by employers, and should employees refuse to participate they would face significantly higher insurance costs.

Too much personalisation is likely to be intrusive. The challenge, then, will be to harness the potential of genomics while introducing measures to keep government and big business in check. The UK House of Commons Science and Technology Committees inquiry on genomics and genome editing was cut short (due to the recent snap general election). Its recommendations for further lines of enquiry include creating a quasi-independent body, which could be more attuned to broader, social and ethical concerns. This might introduce more balance at a pivotal time for the future of human genetic technologies.

DNA used to identify immigrant remains in Mexican border – Concord Monitor

Posted: at 7:49 am

Rolando Arriaza has visited hospitals, morgues and even the harsh, mesquite-covered terrain in South Texas that his brother trekked nearly two years ago after illegally crossing into the U.S. all as part of an ongoing effort to find his siblings remains and bring his family closure.

You want to know if he died and you want to find the body, said Arriaza, whose 50-year-old brother Hugo Arriaza, from Guatemala, disappeared in August 2015 after being abandoned by a smuggler when he became ill.

Like many family members of missing immigrants, Arriaza, 45, has submitted DNA so it can be compared to remains found along the Texas-Mexico border. But while Arriaza, who lives in Philadelphia, submitted DNA to U.S. authorities, many others choose a different path that complicates potential identification of their loved ones remains. Many missing immigrant family members living outside the U.S., or who live in the country but fear going to authorities due to concerns about their immigration status, instead give their DNA to non-governmental organizations working on this issue.

But advocacy groups say these families DNA samples are being denied access to an FBI database used to make matches in missing persons cases because law enforcement didnt collect the sample. The groups say this issue has gone unresolved for years, leaving unused a valuable source of genetic data that could bring closure to hundreds of cases.

How big is the problem, and how somber are the findings? More than 2,900 immigrants have died while crossing the Texas-Mexico border alone since 1998, according to the U.S. Border Patrol. But its unclear how many remain unidentified.

Since 2003, 222 of 879 cases of unidentified human remains sent from Texas border counties to the University of North Texas Center for Human Identification have led to identifications. But the center which works with law enforcement on missing persons cases cautions theres no way to definitively say if the identified remains belong to immigrants.

A review of reports on the National Missing and Unidentified Persons Systems database shows more than 320 unidentified remains found along the Texas-Mexico border since 2007 are likely immigrants.

A large number of immigrant remains in Texas have been found in Brooks County, where authorities about four years ago discovered many had been haphazardly buried in a local cemetery. The county is home to a Border Patrol checkpoint 70 miles north of the border that immigrants avoid by walking around it for days. Arriazas brother was attempting to do so when he disappeared.

Kate Spradley, a biological anthropologist at Texas State University in San Marcos helping identify remains found in Brooks County, said shes frustrated by the slow identification pace. Her lab has received 238 sets of remains but only 24 have been identified. Most are from Brooks County, but some are from other counties, including 13 sets exhumed in May in Starr County.

The DNA samples that are collected by (non-governmental organizations) in Latin America are what we need to make identifications, she said. Complicating Spradleys efforts is a lack of funding, including a loss this year of a federal grant.

Spradley said access to more family member DNA would be welcomed as six more cemeteries in several other South Texas counties have been identified where immigrants were buried.

Texas law mandates DNA samples from unidentified remains must go to the University of North Texas, which sends them to the FBIs Combined DNA Index System, or CODIS database. But per FBI rules, samples from potential family members not collected by law enforcement are denied access to CODIS.
