US petroleum dependency factor of history When the Drake Oil Well in Titusville, Pennsylvania began seeping crude oil 150 years ago, humanity allowed itself to become engulfed in the ecology of oil, according to a Penn State environmental historian. Now in the midst of an energy transition, the US and the world need to keep moving forward toward alternative methods of power generation. Contact: A'ndrea Elyse Messer Public Release: 14-Feb-2009
Cosmologist Paul Davies explores notion of 'alien' life on Earth Astrobiologists have often pondered "life as we do not know it" in the context of extraterrestrial life, says Paul Davies, an internationally acclaimed theoretical physicist and cosmologist at Arizona State University. But has there been a blind spot to the possibility of "alien" life on Earth? Davies will challenge the orthodox view that there is only one form of life in a lecture titled "Shadow Life: Life As We Don't Yet Know It" at the annual AAAS meeting.

Nanoparticle toxicity doesn't get wacky at the smallest sizes The smallest nano-sized silica particles used in biomedicine and engineering likely won't cause unexpected biological responses due to their size, according to work presented today. The result should allay fears that cells and tissues will react unpredictably when exposed to the finest silica nanomaterials in industrial or commercial applications. The researchers concluded this by using total surface area as a measure of dose, rather than particle mass or number of particles. Contact: Mary Beckman Public Release: 14-Feb-2009
Climate change may alter malaria patterns Temperature is an important factor in the spread of malaria and other mosquito-borne diseases, but researchers who look at average monthly or annual temperatures are not seeing the whole picture. Global climate change will affect daily temperature variations, which can have a more pronounced effect on parasite development, according to a Penn State entomologist.

Breaking the barrier: Discovery of anti-resistance factors and novel ocean drugs Investigations into coral disease, red tides and other marine environmental issues have led to discoveries of new chemicals as a source for pharmaceuticals. These chemicals function as antibiotics for microorganism providing survival advantages and may be usable in human health care. We believe that one could apply many of these chemical mechanisms or novel pharmaceuticals to human disease resulting in a number of alternatives to deal with growing antibiotic resistance.

New resource for teachers, public on how to recognize science when you see it How does science work? While scientists are often hard put to explain the process, a new resource called "Understanding Science" helps students, teachers and the public decide what is and is not science and understand the messy but fun adventure of science. Funded by NSF and built by UC Berkeley researchers, the Web site corrects the linear, cookbook-like approach commonly taught, instead showing the often circuitous route leading from idea to discovery.

UK leading the way in corneal research Extremely intense X-rays from Diamond - the UK's national synchrotron - are helping to advance research into the understanding and treatment of eye diseases. Due to the detailed nature of the experiments, researchers from Cardiff University are making discoveries about the eye that should help to advance laser surgeries such as LASIK and contribute to the eventual development of an artificial cornea.

Biofuels, like politics, are local Field work and computer simulations in Michigan and Wisconsin are helping biofuels researchers understand the basics of getting home-grown energy from the field to consumers. Preliminary results presented today from the US Department of Energy's Great Lakes Bioenergy Research Center suggest that incorporating native, perennial plants during biofuels production reduces emissions of greenhouse gases, improves water quality and enhances biodiversity. The results are part of an experimental effort to make biofuels economically and environmentally sustainable. Contact: Mary Beckman Public Release: 13-Feb-2009
Dealing with taxonomic uncertainty for threatened and endangered species As part of a symposium on "Defining species for threatened and endangered protection" Barbara Taylor, Ph.D., NOAA Fisheries Service, will discuss the need to explicitly consider uncertainty in taxonomy in conservation decisions. Species concepts continue to be a contentious, but largely philosophical debate among academic biologists. How differences between groups of organisms are identified, however, can have real, on-the-ground policy implications for which species receive legal protection under the federal Endangered Species Act.

Swimmers at public beaches show increased risk of exposure to contagious staph bacteria University of Miami's Oceans and Human Health Center along with Florida DOH, CDC and EPA jointly sponsor a first-ever epidemiological study of sub-tropical ocean beaches and present preliminary findings at the AAAS meeting in Chicago. Swimmers at public beaches show increased risk of exposure to contagious staph bacteria. Contact: Barbra Gonzalez Public Release: 13-Feb-2009
Engineers create intelligent molecules that seek-and-destroy diseased cells Current treatments for diseases like cancer typically destroy nasty malignant cells, while also hammering the healthy ones. Using new advances in synthetic biology, researchers are designing molecules intelligent enough to recognize diseased cells, leaving the healthy cells alone. "We basically design molecules that actually go into the cell and do an analysis of the cellular state before delivering the therapeutic punch," said Christina Smolke, assistant professor of bioengineering who joined Stanford University in January.

What biology and evolution can teach us about our safety: A tribute to Darwin What do biology and evolution teach us about our own security? In a symposium Feb. 13 at the annual meeting of the American Association for the Advancement of Science in Chicago, paying tribute to Charles Darwin, UCLA behavioral ecologist Daniel T. Blumstein, shares lessons and insights from Darwin that can be applied to our own safety. Contact: Stuart Wolpert Public Release: 13-Feb-2009
The science suggests access to nature is essential to human health Considerable research supports the idea that nature is essential to the physical, psychological and social well-being of the human animal. Contact: Diana Yates Public Release: 13-Feb-2009
When it comes to elephant love calls, the answer lies in a bone-shaking triangle Caitlin O'Connell-Rodwell, an ecologist and consulting assistant professor in otolaryngology at Stanford University School of Medicine, has been studying elephant communication for more than 15 years. During that time she's puzzled over which or their two seismic sensing systems -- either bone conduction or somatosensory reception -- elephants use most often in locating the source of a call. In her most recent field season last summer, she finally got an answer. Contact: Louis Bergeron Public Release: 13-Feb-2009
Mass media often failing in its coverage of global warming, says climate researcher "Business managers of media organizations, you are screwing up your responsibility by firing science and environment reporters who are frankly the only ones competent to do this," said climate researcher and policy analyst Stephen Schneider, in assessing the current state of media coverage of global warming and related issues. Schneider is a coordinating lead author of chapter 19 in the report of the Intergovernmental Panel on Climate Change published in 2007. Contact: Louis Bergeron Public Release: 13-Feb-2009
Tracking the digital traces of social networks Northwestern University researchers have studied the massive online virtual world Second Life to test whether or not certain social theories are true. Having access to huge amounts of data gave them a way to answer how networks are created. Searching through anonymized data from Teen Grid, where only teenage players can socialize, the researchers found that teens' online friendships were disproportionately with people in their immediate geographic area -- likely with people they already knew.

Seeing the forest and the trees helps cut atmospheric carbon dioxide Putting a price tag on carbon dioxide emitted by different land use practices could dramatically change the way that land is used, according to research presented today at the American Association for the Advancement of Science annual meeting. When all carbon emissions -- fossil fuel, industrial and land-use change emissions -- are included in a global management plan, deforestation slows and could reverse, managers place limits on the expansion of biofuels production, and emission control becomes cheaper.
