A shift in the global research landscape will reposition the United States as a major partner, but not the dominant leader, in science and technology research in the coming decade, according to a Penn State researcher. However, the U.S. could benefit from this research shift if it adopts a policy of knowledge sharing with the growing global community of researchers. "What is emerging is a global science system in which the U.S. will be one player among many," said Caroline Wagner, associate professor of international affairs, who presented her findings today (Feb. 18) ...

Fierce debate over teaching evolution in public schools has raged across the United States since the epic courtroom battle between William Jennings Bryan and Clarence Darrow during the 1925 Scopes Monkey Trial (State of Tennessee v. John Scopes). Science education researchers are now turning their attention to the Islamic world to determine whether teaching of evolution in schools spawns similar social controversy and what that means for the future of scientific thought across the globe. Jason Wiles, assistant professor of biology in Syracuse University's College of ...

A central challenge facing the planet is how to preserve forests while providing enough food to feed the world's population. It's really a "bad news/good news" story, says Eric Lambin, professor of environmental Earth system science and senior fellow at the Woods Institute for the Environment at Stanford; and professor of geography at the University of Louvain. The bad news: The world might run out of productive agricultural land by 2050, thanks to rising global demand for food, biofuels, and forest products, along with land degradation and urbanization. The good news: ...

Researchers need to use all available resources in an integrated approach to put agriculture on a path to solve the world's food problems while reducing pollution, according to a Penn State biologist. Changes in national and international regulations will be necessary to achieve this goal. "Using resources more efficiently is what it will take to put agriculture on a path to feed the expected future population of nine billion people," said Nina Fedoroff, Evan Pugh Professor of Biology and Willaman Professor of Life Sciences, Penn State. "We especially need to do a better ...

PROVIDENCE, R.I. [Brown University] — When obsessive-compulsive disorder is of crippling severity and drugs and behavior therapy can't help, there has been for just over a year a thread — or rather a wire — of hope. By inserting a thin electrode deep into the brain, doctors can precisely deliver an electrical current to a cord of the brain's wiring and soften the severity of the symptoms. "Deep brain stimulation" therapy for OCD won Food and Drug Administration approval in 2009 for extreme cases under its humanitarian device exemption. On Feb. 18 at the annual meeting ...

The United States' preoccupation with national security, including counterterrorism, counterintelligence, and cyber security, is also a concern of higher education, according to Graham Spanier, president of Penn State University.

WASHINGTON, D.C. – Asthma diagnosis and management vary dramatically around the world, said David Van Sickle, an honorary associate fellow at the University of Wisconsin School of Medicine and Public Health, during a presentation today at the annual meeting of the American Association for the Advancement of Science (AAAS). Asthma affects an estimated 8 percent of Americans, and about 300 million people around the world, but varying practices in diagnosis and treatment have global implications in understanding a widespread, chronic condition, says Van Sickle, who applies ...

Infants raised in households where Spanish and Catalan are spoken can discriminate between English and French just by watching people speak, even though they have never been exposed to these new languages before, according to University of British Columbia psychologist Janet Werker. Presented today at the American Association for the Advancement of Science (AAAS) Annual Meeting in Washington, DC, Werker's latest findings provide further evidence that exposure to two native languages contributes to the development of perceptual sensitivity that extends beyond their mother ...

Predatory fish such as cod, tuna, and groupers have declined by two-thirds over the past 100 years, while small forage fish such as sardine, anchovy and capelin have more than doubled over the same period, according to University of British Columbia researchers. Led by Prof. Villy Christensen of UBC's Fisheries Centre, a team of scientists used more than 200 marine ecosystem models from around the world and extracted more than 68,000 estimates of fish biomass from 1880 to 2007. They presented the findings today at the American Association for the Advancement of Science ...

When people on airplanes ask Alan Newell what he works on, he tells them "flower arrangements." He could also say "fingerprints" or "sand ripples" or "how plants grow." "Most patterns you see, including the ones on sand dunes or fish or tigers or leopards or in the laboratory – even the defects in the patterns – have many universal features," said Newell, a Regents' Professor of Mathematics at the University of Arizona. "All these different systems exhibit strikingly similar features when it comes to the patterns they form," he said. "Patterns arise in systems when ...

WASHINGTON, D.C. — Introductory college science classes need to improve their coverage of issues related to sustainability, a noted chemistry educator told the American Association for the Advancement of Science today.
