News: AAAS 2011 Annual Meeting News

http://news.aaas.org//2011/index.shtml


Washington, D.C., is not just a political capital—it’s an international science capital, too. The National Science Foundation, the National Institutes of Health, the National Academies, the Smithsonian, and even the Jefferson Memorial testify to the central place of science and scientists in the nation’s past and its future. Thousands of scientists, engineers, policymakers, educators, and journalists from some 50 nations are here at the 177th AAAS Annual Meeting to explore a broad range of recent discoveries and looming global challenges. The AAAS Office of Public Programs is providing news coverage, plus a sampling of Annual Meeting news from around the world.
For three years as science adviser at the U.S. State Department and USAID, Nina Fedoroff urged the world research community to collaborate on “truly global problems that do not respect political boundaries or political positions.”
“It’s never been more important for scientists to work together on the big issues confronting the world: food, energy, and water,” Fedoroff said in a recent interview. As the incoming AAAS president, she will encourage the association to further expand its international programs, especially in developing nations.
Commercial fishing operations in the past 40 years have precipitated a dramatic change in ocean fish stocks, with tuna and other big predators declining and small fish like anchovies and sardines surging. That’s the conclusion of the most ambitious study ever completed of fish populations in the Earth’s oceans, led by Villy Christensen of the University of British Columbia's Fisheries Centre.
In the past 100 years, 80% of the biomass of fish in the world’s oceans has been lost, Christensen says in a AAAS video that coincided with a symposium at the Annual Meeting. “Just in the last 40 years, we have lost 60% of the biomass,” he explained. “So we’ve seen some very serious declines, and there’s no doubt about what the cause is: We’re talking about overfishing—overfishing at the global scale.”
Only a few studies have tried to assess the future of fish populations in the ocean, and they range widely, from complete collapse of marine fish populations by 2048 to improvement in populations. But effective management strategies will be required to achieve the latter outcome, he said.
The story received extensive news coverage internationally.
Food prices are climbing again, sparking public protests in some developing nations. Already there are about 1 billion people in the world who are chronically hungry. And policy makers, looking to the future, are assessing how much more difficult the challenge could get by 2050, when another 2 billion people will push the world population to 9 billion.
Compounding their concerns: Rising income levels in developing countries drives demand for more and better food. Declining reserves of fresh water. And changes in temperature, wind, and flooding that could prove detrimental to crop production.
“By 2030 we are going to need 50% more food, 40% more available fresh water, and something on the order of 50% more low-carbon energy,” Sir John Beddington, the chief science adviser to the U.K. government, told a symposium at the AAAS Annual Meeting. “We need a radical redesign of global food systems.”
AAAS President Nina V. Fedoroff, a plant biologist from Penn State, warned the audience that agricultural romanticism and nostalgia could check human efforts to produce food efficiently with the least environmental impact.
Is antisocial behavior rooted in genetics or is it to some extent acquired through environmental influences? And what is the link between brain structure and criminal or psychopathic behavior?
The questions are crucial for society--they shape how we might try to prevent crime and how we might punish or rehabilitate criminals.
For generations, we have viewed crime at least partly as a moral issue, and the criminal as someone morally corrupted. But research discussed at the Annual Meeting suggested that anti-social behavior may be more likely when the front lobe of the brain is smaller than average or the when amygdala is unusually small or active.
“The seeds of sin are sown quite early on in life,” said criminologist Adrian Raine. 

Biological sciences have been transformed in recent years as new fields such as genomics, proteomics, synthetic biology, and systems biology have come online. Yet through it all, undergraduate biology education has remained largely unchanged.

Now, after years of collaboration among biology students, professors, and researchers, the U.S. National Science Foundation, AAAS, and their partners have released Vision and Change in Undergraduate Biology Education: A Call to Action. The new publication charts a course for bringing more contemporary, multi-disciplinary instruction into undergraduate biology classrooms and dramatically modernizing the ways that biological sciences are taught in universities across the United States.

“The publication of Vision and Change is a start,” said Bruce Alberts, the editor-in-chief of the journal Science. “It's now time for action.”

The publication was released Saturday 19 February at the Annual Meeting.

After agreeing to participate in a small study on exposure to environmental toxins, a woman learned she had traces of 109 potentially harmful chemicals in her body, including PCBs and dioxins. Her first reaction: "absolute outrage."
But her case represents an increasingly important issue for researchers. They are asking people for blood, tissues samples, and breast milk so that they can study toxins in the enivronment, and people want to know their individual results.
As a result, experts said at the Annual Meeting, researchers are searching for ways to report these results that are personally useful but also honest about the uncertainties of chemical exposure.
The Sun has a cycle of activity that usually lasts about a dozen years--and right now, the latest quiet period appears to be coming to a close. That could portend tough times ahead for your radio, your GPS, and for those who are directing the flight and path of smart bombs against military targets. 

A forum at the AAAS Annual Meeting focused on these issues and Science’s Robert Coontz caught up with panelist Thomas Bogdan, director of National Oceanic and Atmospheric Administration (NOAA) Space Weather Prediction Center, in this Science Podcast.

In Bogdan’s view, the spectacular Valentine’s Day solar flare that generated worldwide news coverage wasn’t so unusual. “These were not the largest of storms,” Bogdan said. “I think they garnered a lot of attention because they were the largest storms we’ve seen in about four years.”

Earth is protected from much of the Sun’s radiation by its magnetic field, but sensitive electronics can be vulnerable. That is particularly true of satellites whose electronic circuits can be fried if they are not protected from the energy surges. Scientists are warning that a really large solar storm could wreak havoc on electronics comparable to Hurricane Katrina, but on a global scale.
Scientist as comedian--are you trying to be funny? But seriously: Brian Malow has a knack for infusing scientific topics with humor and wordplay. And during standing-room-only presentation Sunday at the Annual Meeting, Malow said that humor is too often overlooked an effective way for scientists to connect with a non-scientific audience.
Malow had his audience laughing throughout his presentation. But he also offered good, practical advice for how to be funny, and the advice can serve scientists and anyone else who's getting ready for a public presentation.
Among his key recommendations: Know your audience. Use stories and anecdotes to make a human connection. Steal other people's lines and make them your own, if you need to (with attribution, of course).
And in a pinch, it's a good bet to just to look amused. “It’s good to look like you’re about to say something funny…you are funny,” Malow says. “Trust me, people are laughing at you.”
MIT undergraduates must take an introductory biology class, and Graham Walker teaches hundreds of these students in a semester. Somewhere in those classes are the next superstars of science, he said, and he's determined to find them.

Science education can sometimes turn into a "bulk experiment," where the goal is to get an average number of students to learn an average amount, he said in a plenary talk at the close of the 2011 AAAS Annual Meeting. But his experiences have impressed him with the diversity of learning styles and motivations of individual students, and he challenges himself to teach "at the single molecule" level, reaching out to each student in a way that will ignite his or her personal interest in science.
The AAAS Annual Meeting in Washington, D.C., ended Monday after an exciting five-day run. But in the days ahead, we'll be adding more meeting coverage to this site, including stories on: 

  • biosecurity; 
  • feeding the world's growing population; 
  • the politics of climate change;
  • the science of comedy; and
  • new AAAS President Nina Fedoroff.
Check back over the next few days for more news from the cutting edge of science.
 
DNA sequencing is getting easier and cheaper. Thousand of researchers nationwide have access to bacteria and viruses considered potentially dangerous to human health. And scientists and law enforcement agencies sometimes have very different ideas about how to approach regulation and security.
In an environment that holds great promise for advancing medical care and improving environmental clean-up, it's clear that the United States is still wrestling with how to limit the risks. At the AAAS Annual Meeting, a panel discussion featuring some eminent experts in research and science policy urged that a careful balance be struck so that, as much as possible, security is ensured without compromising research.
Ten years after the anthrax attacks that killed five Americans, researchers say a “culture of responsibility” among scientists may be the most effective way to prevent a future biological attack. 
Stuttering--and ways to ease the condition--have taken on a new visibility since release last fall of "The King's Speech," the acclaimed film which follows the inspiring effort of Britain's King George VI to control his stammer.
But research and treatment has come a long way since King George's era. Gone are the days when it was considered a product of poor parenting or a sign of nervousness. Genes gone awry and brains working in overdrive are now considered the more likely culprits.
From studies on hand-clapping in children to stuttering mice, scientists at the AAAS Annual Meeting reported that recent research is approaching the puzzle from different directions. They're hoping to converge soon on a detailed biological model that will explain why stuttering starts when it does, why some people are more susceptible, and what sorts of therapies are the best at treating the speech disorder.
UPDATE 2/22: Science Update, the smart, quirky 60-second daily radio show from AAAS, has a new segment on the latest stuttering research.
Science Update, the award-winning radio show from AAAS, visited the Annual Meeting this week, and in a new podcast Bob Hirshon and Susanne Bard explore some of the meeting's most intriguing stories: the new science of aeroecology, fresh insight into human taste preferences, novel ways to store energy, and 3-D printers that could one day produce replacement organs.
Science Update is a 60-second radio show broadcast five days a week on radio stations all over the United States. Once a week there's a new podcast that includes a number of stories. It's top-notch science reporting--quick, a little quirky, and highly informative. It was first broadcast in 1988, and celebrated its 5000th episode last July.

AAAS President Alice S. Huang's own practice of science diplomacy--in the lab and on the international stage--has convinced her of its power to address global problems such as poverty and women's economic advancement.
"The United States has tremendous credibility to engage other countries in science diplomacy," she said in her presidential address at the 2011 AAAS Annual Meeting, "because of our own capabilities in science and technology."
For the U.S. to succeed, she said, "we need to avoid arrogance and Western-centric views, and behave as true partners in advancing international science as well as the welfare of all citizens."
In a crowded room at the AAAS Annual Meeting, researchers were talking about the benefits of being able to “print” biological materials. Nearby, a machine rested on a stool, draped in a white cloth; the machine hummed as a carriage shifted back and forth, its gel-filled jet tracing a precise pattern over the flat work surface.

The talk passed into a Q&A session, and the machine hummed on. By the time questions were answered, the Fab@Home 3D printer had completed its project: a silicon model of human ear cartilage.
The idea is derived from a common inkjet printer, but researchers are hoping to develop its capacity to build new skin and treat grave wounds, printing one thin layer at a time. 
A single letter in an individual’s DNA determines whether or not that person is likely to become infected with Plasmodium vivax, the world’s most common malaria parasite. New evidence suggests that the parasite may be evolving a way around this genetic hurdle to gain the ability to infect even more people.

Malaria already is one of the leading causes of death around the world, with 2.85 billion of the Earth’s 7 billion people at risk for the infection. And it is a re-emerging problem in the United States, as warming temperatures are helping malaria become reestablished in the American South.

If this new variant of the parasite gains a foothold on the continent of Africa, then millions of people once thought to be resistant to the bug “suddenly become susceptible to a new form of malaria,” Peter Zimmerman said during a news briefing at the AAAS Annual Meeting. Zimmerman is a professor of global health at Case Western Reserve University School of Medicine.
White House Executive Pastry Chef William Yosses came to the AAAS Annual Meeting to embroider on a general theme: Flavor—sweet, salty, tart, bitter—“is a concept created in the brain.” Ah, but what a concept!
At a symposium on the science of food and flavor, Yosses and others fluent in that delightful science explored our attraction to really good foods--even when they're potentially really bad for us. Salt, for example, was singled out for a lot of attention.
“If our genetic disposition is to savor fat, and salt, and things that are bad for us,” Yosses asked rhetorically, “what is a chef to do?” He had some appealing ideas about that, too.
Even as the federal government nears a possible shutdown next month over a delayed budget and many in the U.S. Congress call for severe spending cuts, the nation's chief science adviser said President Barack Obama remains committed to science and technology investments as essential drivers of the country's economic future.
John P. Holdren, director of the Office of Science and Technology Policy, said that from clean energy to electronic health records, Obama "realizes that science and technology are not just germane to success, but central."  And Holdren reassured his audience that the president's concerns reach beyond research spending to supporting the broader science enterprise, from education to commercial applications.
In a plenary address to the 2011 AAAS Annual Meeting, enthusiastically received by a standing room-only crowd of more than1500, Holdren shared his insights on a president deeply engaged in the details of science policy, convinced of its importance to the country's future, and personally delighted by the discoveries of scientists and students.
Bioengineer Frances Arnold wants to make microbes into the chemical factories of the 21st century. But she learned long ago that her designing skills pale alongside the handiwork of evolution. So like any good entrepreneur, she decided to hire the competition.
Those who direct the power of evolution successfully, she told her audience at the 2011 AAAS Annual Meeting, can create new medicines, new fuels, and new materials in a sustainable and efficient fashion.
“This is a very rich and intricate composition, the code of life, and we don’t know how to write music like this,” she said. “We’re just learning how to hold a pencil when it comes to comparison with the code of life.”

A performance combining music, dance, and sculpture with science captivated a large audience Saturday at Family Science Days during the AAAS Annual Meeting. Lelavision Performance Company along with David Lynn, professor of chemistry at Emory University, performed “The Evolution of Life.”

Family Science Days is an opportunity--open to the public without charge--to enjoy hands-on exhibitions and engage with a variety of scientists and science organizations. Everything from dry ice experiments to colorful paints and crafts were popular features at the exhibitions.

Family Science Days continues on Sunday at the Walter E. Washington Convention Center in Washington, D.C.
When the news media cover issues like evolution and embryonic stem cell research, scientists and evangelical Christians often are portrayed as implacable opponents. But speakers at the AAAS Annual Meeting said there is another, quieter trend toward partnership between the two communities, one that offers hope for working together on important areas of science policy.
In their symposium, the scientists and ethicists suggested practical reasons for working with the politically active evangelical community. On issues like stem cell research, constructive engagement might temper conflict and allow research to move forward. On environmental stewardship and climate change, shared values can be a basis for effective partnerships.
The ideal working relationship between the two groups, said University of Virginia professor James Childress, would produce "policies that can address a range of ethical concerns but also be faithful to the science involved."
Ethanol is increasingly seen as inefficient. At least one major oil company is looking to derive fuel from algae. And now a Swedish researcher in synthetic biology is exploring whether a common form of yeast, long associated with baking and brewing, could itself be turned into fuel, chemicals, and proteins.
Jens Nielsen, a systems and synthetic biologist at Chalmers University of Technology in Gothenburg, Sweden, said much is already known about how to manipulate the organism. His group has modified yeast through genetic engineering to change the metabolism of the cells and produce desired chemical feedstocks in greater quantities.
But at a AAAS Annual Meeting symposium, Nielsen said that many challenges lie ahead. Among them: the need for computational tools that are tailored for industrialized application of synthetic biology products.
NASA's Kepler mission has helped detect about 1200 "candidate" planets so far, but for William Chaplin, what's striking is this: The resonating sounds within a star make it quake and pulse in tiny but predictable ways, like music. And that could help astronomers in their search for Sun-sized starts that shelter Earth-sized planets.
Chaplin's research in the new field of asteroseismology is one of the lesser-known highlights of the Kepler mission, a space-based telescope launched in 2009 to explore a portion of the Milky Way galaxy for Earth-like planets. On Saturday at the Annual Meeting, Kepler researchers discussed the data gleaned by the telescope in its first years, surveying its designated patch of sky in the constellations Cygnus and Lyra.
Already, said MIT planet scientist Sara Seager, Kepler has notched some strange and incredible finds.
Learning a second language can improve your work skills or your travel experience, but new research is showing that it also appears to confer other, unexpected advantages: It actually makes the brain more healthy and more efficient.

In presentations at the AAAS Annual Meeting, researchers detailed findings that show learning a second language can sharpen focus and other cognitive abilities and even hold off the effects of dementia.

An episode of Science Podcast, hosted by Robert Frederick, tapped into two Friday symposia. Frederick’s take-home: Being multilingual can actually influence learning and the brain structure, with impacts extending throughout one’s life.
“We don’t believe bilingualism prevents Alzheimer’s disease," said psychologist Ellen Bialystok in an interview with Science Update, the daily 60-second radio show from AAAS. "What we’re saying is, people who have been bilingual have more reserve, they have more resources to continue functioning at a high level in spite of the disease progressing in their brains.”
The story got extensive global coverage--including the Guardian, Agence-France-Presse, and National Geographic online. Mais oui!
The news team at Science is hosting a series of live chats with top scientists at this year's AAAS Annual Meeting. Today at noon, the guest will be Tom Kunz, whose research focuses on the ecology, behavior, evolution, and conservation biology of bats.

Humans have evolved a symbiotic, co-dependent relationship with specialized communities of microorganisms that colonize every part of our body, from the space between our toes to the roof of our mouths and the recesses of our gut.
But what happens if the natural microbial ecology--in our intestines, for example--is thrown out of balance? Researchers at an Annual Meeting symposium Friday said they're now exploring whether autism, Type II diabetes, and other conditions may be linked to such disruptions.

Modern medicine was founded on the discovery that microorganisms are a cause of disease. It has taken several hundred years to begin to realize that they also can be beneficial to our health, Dr. David Relman, a Stanford University professor, told the symposium.
Despite continuing budget challenges, President Barack Obama is committed to supporting areas of research and development investment that are critical for the nation's long-term economic strength," White House science adviser John P. Holdren said Friday at AAAS.
In a news briefing with U.S. and foreign reporters, Holdren said the 2012 budget proposed by the president reduced funding for an array of valuable science-related programs. But the president signaled his economic vision and policy priorities by providing increases of approximately 6% for some civilian R&D and about 5% for all basic and applied research combined.
For the Department of Energy, NASA, and the National Oceanic and Atmospheric Administration, the White House has proposed "double-digit," increases for research, Holdren told reporters. "This is not the time to stop investing in the drivers of the economic growth we need for recovery," he said.
Flying animals, changing weather conditions, and human architecture mingle in complicated ways within the lowest levels of the atmosphere. Two years ago, Boston University biologist Thomas Kunz coined the term "aeroecology" to describe the science of this unique borderland skimming the surface of the planet.
The new discipline combines atmospheric science, geography, ecology, and computational science in ways that even its pioneers could not have predicted, researchers said Friday at the AAAS Annual Meeting.
In one image, molecules appear to ripple like water on a surface of gold. Another shows the human immunodeficiency virus in striking 3D detail. And a video shows how 3000 pieces of trash, tagged with sensors in Seattle, flow to destinations throughout the United States.
These were among the winners of the 2010 International Science and Engineering Visualization Challenge announced Thursday by the U.S. National Science Foundation and AAAS. Though they use different media and focus on subjects as diverse as molecules, fungi, and tomato seeds, all of the winners have a common accomplishment:
They use pictures to engage people worldwide and to convey science in creative, almost irresistible, ways.
Probing environmental reports on the size of the Gulf oil spill, the possible risks of chemicals commonly found in drinking water, and the fate of an endangered fish in the Colorado River are among the winners of the 2010 AAAS Kavli Science Journalism Awards.
The awards, administered by AAAS since their inception in 1945, go to professional journalists for distinguished reporting for a general audience. The Kavli Foundation, based in Oxnard, California, provided a generous endowment in 2009 that ensures the future of the awards program.
Independent panels of science journalists pick the winners, who will be honored in a ceremony Friday evening at the Annual Meeting in Washington, D.C.

Former U.S. Army Sergeant Glen Lehman lost an arm during battle in Iraq, and you watch with a mix of admiration and awe as he demonstrates some cutting-edge robotic technology: He has an artificial arm wired to his body now, and when he thinks about moving the arm, it moves.
The demonstration was one of several yesterday at the AAAS Annual Meeting that offered a glimpse of the emerging power and potential that may someday be tapped when human minds are connected to machines.
Adaptive optics, a technique used to peer into the center of the Milky Way, is now turning its gaze on tiny blood vessels in the eye and neurons in the mouse brain, experts said at a symposium at the 2011 AAAS Annual Meeting.
The sight of a star--or cell--is never a perfect one, as light waves bounce and bend in unpredictable ways as they make their way from the object to the eye. Adaptive optics measures and compensates for these deflections to create a sharper image.
Most children learn early that bears hibernate through the winter, but, perhaps surprisingly, researchers have had limited insight into what goes on during that big sleep. Now researchers from the University of Alaska at Fairbanks have developed some interesting new insight.
Their findings show that although black bears reduce their body temperatures only slightly during hibernation, their metabolic activity drops dramatically, slowing to about 25% of their normal, active rates. Their heart rates slowed from around 55 beats per minute to about 14 beats per minute.
The findings have implications for a range of human endeavors—from medical care to deep space travel.
Øivind Tøien and a group from the Institute of Arctic Biology at the University of Alaska at Fairbanks, along with colleagues from Stanford University, reported their findings in the 18 February issue of Science and discussed them during a news briefing on the findings on the opening day of the 2011 AAAS Annual Meeting in Washington, D.C.
[UPDATE 2/18: This story received widespread news coverage, including stories by Joe Palca, NPR; Alan Boyle, msnbc.com; Brian Vastag, Washington Post; and Jeffrey Kluger, Time.com.] 
The news team at Science is hosting a series of live chats with top scientists at this year's AAAS Annual Meeting. The first chat takes place today at noon.

AAAS President Alice S. Huang said that overt discrimination against women in science "is pretty well gone," but women are still less likely to hold management-level positions in government, industry, and academia.

"It seems as if the bar is set higher for women," said Huang, who spoke before international media at the start of the 2011 AAAS Annual Meeting. She called the advancement of women and minorities in science one of her lifelong passions.
The 177th AAAS Annual Meeting formally opens today in Washington, D.C. The pace accelerates today before a full day of events on Friday.

If you love science, and if you're anywhere near Washington, D.C., in the next several days, then the AAAS Annual Meeting has some amazing programs for youfor freewhether you're a teacher, a dad with some adventurous kids, or an early career scientist. Or maybe you'd love to learn how a pioneering researcher and her team are generating novel enzymes and organisms for use in medicine and in alternative forms of energy.

Family Science Days, to be held the weekend of 19-20 February, is an institution at the Annual Meeting that gets better every year. This year, there will be presentations on biologically inspired robots and experiments for daring young scientists, plus, for middle- and high school students, a series of short, interactive presentations by leading scientists. 

The meeting also includes cutting-edge lectures on topics such as climate change and biosecurity, along with career-building presentations for scientists of every age.
Registration for these free events is required on-site at the Walter E. Washington Convention Center in downtown D.C.

Brain-controlled tele-presence robots, “smart” artificial limbs, bioprinting strategies for regenerative medicine, the next generation of batteries, and the search for other Earthsthese are just a few of the topics to be explored as America’s largest general scientific conference convenes starting tomorrow in Washington, D.C.

The AAAS Annual Meeting has been described in The Times Higher Education as “the Olympics of science conferences,” and it's not difficult to see why. The meeting features hundreds of top scientists, policy experts, and leading educators from some 50 nations, many speaking about remarkable new discoveries or critical issues facing humanity.

Included in the lineup for the 177th Annual Meeting are free public lectures by John P. Holdren, President Barack Obama’s assistant for science and technology; Frances H. Arnold, a pioneer in the use of enzymes and organisms for medicine and energy; and Graham C. Walker, Massachusetts Institute of Technology education expert and cancer researcher. 

Registrants will be able to sample symposia and seminars across the range of scienceastronomy, neuroscience, and climate change, the role of innovation in economic growth, the state of U.S. research and development funding, and the importance of science diplomacy.

The AAAS President’s Address will be delivered by Alice S. Huang, the distinguished virologist and proponent for women in science. “The theme for this year’s conference, "Science Without Borders," stresses science’s increasingly global nature and highlights the importance of utilizing multidisciplinary approaches to the practice of science,” Huang said. “It challenges us to break down barriers and embrace diversity so we can leverage science to solve the urgent global problems we face and advance society.”
