Farmers across the tropics might raze forests to plant biofuel crops, according to new research by Holly Gibbs, a postdoctoral researcher at Stanford's Woods Institute for the Environment.

Vitamin E may decrease and increase mortality of male smokers with high dietary vitamin C intake
Six-year vitamin E supplementation decreased mortality by 41 percent in elderly male smokers who had high dietary vitamin C intake, but increased mortality by 19 percent in middle-aged smokers who had high vitamin C intake, according to a recent Finnish study published in the American Journal of Epidemiology.

Mixed population provides insights into human genetic makeup
Genetic diseases and genetically mixed populations can help researchers understand human diversity and human origins according to a Penn State physical anthropologist.

Climate change likely to be more devastating than experts predicted, warns top IPCC scientist
Without decisive action, global warming is likely to accelerate at a much faster pace and cause more environmental damage than predicted, says Stanford scientist Chris Field, a leading member of the Nobel Prize-winning Intergovernmental Panel on Climate Change.

Exploring planets in distant space and deep interiors
In recent years researchers have found hundreds of new planets beyond our solar system, raising questions about the origins and properties of these exotic worlds -- not to mention the possible presence of life.

New data suggest 'jumping genes' play a significant role in gene regulatory networks
Research performed at the UC Santa Cruz Center for Biomolecular Science & Engineering suggests that mobile repetitive elements -- also known as transposons or

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.

What are the mechanisms of PPAR-gamma-inhibiting pancreatic carcinoma growth?
A research group in China investigated the PPAR-gamma activation on the growth of pancreatic carcinoma, especially its regulation on the tumor angiogenesis.

Internet emerges as social research tool
For the past two decades, the Internet has been used by many as an easy-to-use tool that enables the spread of information globally.

Radioimmunotherapy: Promising treatment for HIV infection and viral cancers
Scientists at Albert Einstein College of Medicine of Yeshiva University have piggybacked antibodies onto radioactive payloads to deliver doses of radiation that selectively target and destroy microbial and HIV-infected cells.

AAAS Annual Meeting experts to explore the origin and evolution of planets
Within the past two decades, scientists have found more than 300 planets around stars beyond the sun -- most of them giant gas or ice planets, some of them possibly rocky giants, or

Artificial cells, simple model for complex structure
A simple, chemical materials model may lead to a better understanding of the structure and organization of the cell according to a Penn State researcher.

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.

Decisive action needed as warming predictions worsen, says expert
Greenhouse gases in the atmosphere are rising more rapidly than expected, increasing the danger that without aggressive action to reduce emissions the climate system could cross a critical threshold by the end of the century, warns a leading member of the Nobel Prize-winning Intergovernmental Panel on Climate Change.

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.

Cosmologist Paul Davies explores notion of 'alien' life on Earth
Astrobiologists have often pondered

Michigan State University prof calls for more metro, regional science councils
If science education is to flourish and if science is to be better understood by the general public, then scientists need to think more locally, Michigan State University professor Jon Miller said.

Molecules self-assemble to provide new therapeutic treatments
By tailoring peptide amphiphiles, small synthetic molecules developed at Northwestern University, and combining them with other molecules, Northwestern researchers can make a wide variety of structures that may provide new treatments for medical issues including spinal cord injuries, diabetes and Parkinson's disease.

'Petascale computing' may improve storm predictions, AAAS Annual Meeting speakers report
Scientific computing is rapidly moving to the petascale, a quadrillion arithmetic operations per second, according to speakers at the Annual Meeting of the American Association for the Advancement of Science, scheduled for Feb.
