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 ...

One of the goals of the European Research Council, ERC, is to bring the world's leading researchers to work in Europe. American Juleen Zierath is one of those who have received funds from the ERC. She found the best environment for her research at Karolinska Institutet in Sweden. It's more usual that scientists leave Europe to work in the US. But Juleen Zierath, Professor of Clinical Integrative Physiology at Karolinska Institutet, has travelled in the opposite direction. An American who was educated in the US, she travelled to Sweden to carry out research. She is one ...

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. Spanier, who chairs the National Security Higher Education Advisory Board (NSHEAB), addressed attendees today (Feb. 18) at the annual meeting of the American Association for the Advancement of Science in Washington, D.C., stressing that higher education is part of the national security solution.

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.

According to the study, parents forgive more than children, while women are better at forgiving than men. "This study has great application for teaching values, because it shows us what reasons people have for forgiving men and women, and the popular conception of forgiveness", Maite Garaigordobil, co-author of the study and a senior professor at the Psychology Faculty of the UPV, tells ...

Patients who undergo elective orthopedic surgeries at high-volume, regional hospitals have better surgical outcomes and experience fewer complications than those who undergo those surgeries at local hospitals, according to research being presented by Hospital for Special Surgery investigators at the 2011 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS). These "regionalizers"—patients who travel to a regional, high-volume hospital—also tend to be younger, white, male and have private insurance, according to the research from Hospital for Special Surgery ...

Knee replacement surgery takes far more time to conduct in overweight and obese patients than in normal weight patients, according to recent research at Hospital for Special Surgery in New York. The study will be presented at the American Academy of Orthopaedic Surgeons annual meeting, held Feb. 15-19 in San Diego, Calif. The study has implications for hospital staff scheduling surgeries, operating room utilization and personnel staffing, and also raises the question of whether knee replacements should be reimbursed based on time.

A new study has identified factors that predict the ability of a professional dancer to return to professional performance after hip arthroscopy surgery. The study by Hospital for Special Surgery investigators will be presented at the American Academy of Orthopaedic Surgeons annual meeting, held Feb. 15-19 in San Diego, Calif. The results of this study indicated that ballet dancers were significantly less likely to be able to return to work compared with modern dancers or dance theater performers. Older age and having a variety of hip abnormalities also influenced outcome. ...

(Jena, Germany) Professor Dr. Michael Ristow's team along with Japanese colleagues from universities in Oita and Hiroshima have demonstrated by two independent approaches that even a low concentration of lithium leads to an increased life expectancy in humans as well as in a model organism, the roundworm Caenorhabditis elegans. The research team presents its results in the online edition of the scientific publication European Journal of Nutrition which is now online (see hyperlink below). Lithium is one of many nutritional trace elements and is ingested mainly through ...

From The Royal Botanic Gardens, Kew, The University of Western Australia, and the, Kings Park and Botanic Garden, the scientists argue that deliberately increasing the frequency of fires may lead to ecosystem degradation and loss of biodiversity. In a paper published this month in Trends in Plant Science they acknowledge that as climate change increases the combustibility of vegetation, human lives and property are more at risk. However, they suggest that prescribed burning – a key practice by most environmental managers – may cause more problems because, they say, ...

Planets form in disks of dust and gas that surround young stars. A look at the birth places means a journey into the past of the earth and its siblings. Now, astronomers have been able to obtain detailed images of the protoplanetary disks of two stars using the Subaru telescope in Hawaii. This is the first time that disk structures comparable in size to our own solar system have been resolved this clearly, revealing features such as rings and gaps that are associated with the formation of giant planets. The observations are part of a systematic survey to search for planets ...
