Hubble finds first organic molecule on extrasolar planet
The tell-tale signature of the molecule methane in the atmosphere of the Jupiter-sized extrasolar planet HD 189733b has been found with the Hubble Space Telescope. Under the right circumstances methane can play a key role in prebiotic chemistry - the chemical reactions considered necessary to form life as we know it.

Good luck indeed: 53 million-year-old rabbit's foot bones found
One day last spring, fossil hunter and anatomy professor Kenneth Rose, Ph.D. was displaying the bones of a jackrabbit's foot as part of a seminar at the Johns Hopkins University School of Medicine when something about the shape of the bones looked oddly familiar.

Scientists find color vision system independent of motion detection
The vision system used to process color is separate from that used to detect motion, according to a new study by researchers at New York University's Center for Developmental Genetics and in the Department of Genetics and Neurobiology at Germany's University of Würzburg.

New survey shows allergies dramatically impact sufferers' moods and how they feel about themselves
A new Harris Interactive phone survey conducted among 1,000 allergy sufferers, 1,000 consumers (both allergy sufferers and non-sufferers) and 300 physicians shows that beyond the sneezing, sniffling and watery eyes, allergies also have deep and emotional impacts on a sufferer's mood and self-perceptions.

Clean-vehicle research initiative making progress
A public-private effort to develop technologies for more fuel-efficient automobiles and to investigate the feasibility of hydrogen-based vehicles has made significant progress in most research areas, says a new report from the National Research Council.

Levels of folate in men's diets is linked to chromosomal abnormalities in their sperm
Researchers have found an association between a vitamin found in leafy green vegetables, fruit and pulses and levels of chromosomal abnormalities in men's sperm. Men who consumed high levels of folate (a water-soluble B vitamin that occurs naturally in food) and folic acid (the synthetic form of the vitamin) tended to have lower levels of abnormal sperm where a chromosome had been lost or gained (known as aneuploidy).

A stronger heart with flavonoids
A polyphenols-rich diet keeps the heart younger. This finding comes out from a study by the University of Grenoble in collaboration with the other Centres participating to the FLORA Project, a European Commission funded research studying the effects of flavonoids, a variety of polyphenols, on human health.

Neuronal regulators offer potential targets for cancer
Being too brainy can be a bad thing in a junior high cafeteria, where the social hierarchy favors other traits. "Braininess" also causes problems for cells.

Prostate size and other neglected factors influence prostate cancer treatment satisfaction
Men with prostate cancer and their partners face difficult decisions regarding treatment, and accurate information regarding expected outcomes can be hard to find, according to results of a multi-center study published Wednesday in the New England Journal of Medicine.

Reducing carbon emissions could help -- not harm -- US economy
A national policy to cut carbon emissions by as much as 40 percent over the next 20 years could still result in increased economic growth, according to an interactive website that reviews 25 of the leading economic models used to predict the economic impacts of reducing emissions.

Community-acquired staph pneumonia appears more common, including MRSA
Preliminary research from the Centers for Disease Control and Prevention (CDC) suggests that community acquired pneumonia (CAP) caused by the Staphylococcus aureus bacterium may be more common than originally suspected, including that caused by antibiotic resistant strains.

How Iron Gets into the North Pacific
Most oceanographers have assumed that, in the areas of the world's oceans known as High Nutrient, Low Chlorophyll (HNLC) regions, the iron needed to fertilize infrequent plankton blooms comes almost entirely from wind-blown dust.

Smokers treated for brain aneurysm with coils at higher risk of recurrence
Cigarette smokers who were treated for cerebral aneurysms with coil embolization (blocking of a blood vessel) are at greater risk of developing another aneurysm, say neurological surgeons at Jefferson Hospital for Neuroscience in Philadelphia in the first-known study of its kind.

Stanford researchers developing 3-D camera with 12,616 lenses
The camera you own has one main lens and produces a flat, two-dimensional photograph, whether you hold it in your hand or view it on your computer screen. On the other hand, a camera with two lenses (or two cameras placed apart from each other) can take more interesting 3-D photos.

Less can be more, for plant breeders too
Imagine you are a rice breeder and one day within a large field you discover a plant that has just the characteristics you have been looking for. You happily take your special plant to the laboratory where you find out that the spontaneous, beneficial event was due to inactivation of a single gene.

New regulations tighten controls on restricted chemicals
The Government of Canada is taking action to better control the sale of chemicals that can be used to make explosives. The Honourable Gary Lunn, Minister of Natural Resources, and the Honourable Stockwell Day, Minister of Public Safety, today announced that new regulations for these chemicals, known as explosives precursors, will be implemented under the Explosives Act.

Study verifies that cholesterol-associated gene variants can predict cardiovascular events
A study appearing in this week's New England Journal of Medicine confirms that a combination of gene variants previously associated with cholesterol levels does reflect patients' cholesterol levels and can signify increased risk of heart attack, stroke or sudden cardiac death.

Community-intervention study links successful town makeover focused on boosting calcium and exercise
The battle against obesity in this country could be tackled one community at a time, according to a newly published study in the Journal of Physical Activity and Health. Researchers at the University of Colorado at Denver demonstrated the effectiveness of changing behaviors at a community level, suggesting that community-based interventions could be a viable option to address the nation's obesity epidemic.

Research on consequences: Hyperactive girls face problems as adults
Young girls who are hyperactive are more likely to get hooked on smoking, under-perform in school or jobs and gravitate towards mentally abusive relationships as adults, according to a joint study by researchers from the Université de Montréal and the University College London (UCL).

Floating a big idea: MIT demos ancient use of rafts to transport goods
Oceangoing sailing rafts plied the waters of the equatorial Pacific long before Europeans arrived in the Americas, and carried tradegoods for thousands of miles all the way from modern-day Chile to western Mexico, according to new findings by MIT researchers in the Department of Materials Science and Engineering.
