Probing exoplanets from the ground: A little telescope goes a long way
NASA astronomers have successfully demonstrated that a David of a telescope can tackle Goliath-size questions in the quest to study Earth-like planets around other stars. Their work provides a new tool for ground-based observatories, promising to accelerate by years the search for prebiotic, or life-related, molecules on planets orbiting stars beyond our solar system.

Marijuana ineffective as an Alzheimer's treatment
The benefits of marijuana in tempering or reversing the effects of Alzheimer's disease have been challenged in a new study.

Mediterranean diet may lower risk of brain damage that causes thinking problems
A Mediterranean diet may help people avoid the small areas of brain damage that can lead to problems with thinking and memory, according to a new study.

Will earlier springs throw nature out of step?
(Centre for Ecology & Hydrology) The recent trend towards earlier UK springs and summers has been accelerating, according to a study published today in the scientific journal Global Change Biology. The collaborative study, involving scientists from 12 UK research institutions, universities and conservation organisations, is the most comprehensive and rigorous assessment so far of long-term changes in the seasonal timing of biological events across marine, freshwater and terrestrial environments in the UK.

Study reveals new details on the dangers of third-hand smoke
(DOE/Lawrence Berkeley National Laboratory) Nicotine in third-hand smoke, the residue from tobacco smoke that clings to virtually all surfaces long after a cigarette has been extinguished, reacts with the common indoor air pollutant nitrous acid to produce dangerous carcinogens. This new potential health hazard was revealed in a multi-institutional study led by researchers with the Lawrence Berkeley National Laboratory.

Brown biologist solves mystery of tropical grasses' origin
(Brown University) Brown University biologist Erika Edwards and a colleague have found that rainfall, not temperature, was the primary trigger for the evolutionary beginnings of C4 tropical grasses. Their results are published in the Proceedings of the National Academy of Sciences.

Caltech neuroscientists discover brain area responsible for fear of losing money

Neuroscientists at the California Institute of Technology (Caltech) and their colleagues have tied the human aversion to losing money to a specific structure in the brain–the amygdala.

Method of the future uses single-cell imaging to identify gene interactions

Cellular imaging offers a wealth of data about how cells respond to stimuli, but harnessing this technique to study biological systems is a daunting challenge. In a study published online in Genome Research (www.genome.org), researchers have developed a novel method of interpreting data from single-cell images to identify genetic interactions within biological networks, offering a glimpse into the future of high-throughput cell imaging analysis.

Molecular 'firing squad' in mice triggered by overeating destroys metabolism

Overeating in mice triggers a molecule once considered to be only involved in detecting and fighting viruses to also destroy normal metabolism, leading to insulin resistance and setting the stage for diabetes. The new study, led by researchers at the Harvard School of Public Health (HSPH), specifically links together the immune system and metabolism, a pairing increasingly suspected in diseases that include — in addition to diabetes — heart disease, fatty liver, cancer, and stroke. Understanding how to regulate the molecule through targeted drugs or nutrients could eventually change the way these diseases are prevented and treated in humans. The study will publish in the February 5, 2010, issue of Cell.

Energy released from a virus during infection measured
Researchers has directly measured the energy associated with the expulsion of viral DNA, a pivotal discovery toward fully understanding the physical mechanisms that control viral infection and designing drugs to interfere with the process.
