Gliese 581: 1 planet might indeed be habitable
December 13, 2007 12:42 PM - A&A
More than 10 years after the discovery of the first extrasolar planet, astronomers have now discovered more than 250 of these planets. Until a few years ago, most of the newly discovered exoplanets were Jupiter-mass, probably gaseous, planets. Recently, astronomers have announced the discovery of several planets that are potentially much smaller, with a minimum mass lower than 10 Earth masses: the now so-called super-Earths
Subliminal Smells Bias Perception About a Person's Likeability
December 13, 2007 12:29 PM - Northwestern University Newswire
EVANSTON, Ill. --- Anyone who has bonded with a puppy madly sniffing with affection gets an idea of how scents, most not apparent to humans, are critical to a dog's appreciation of her two-legged friends. Now new research from Northwestern University suggests that humans also pick up infinitesimal scents that affect whether or not we like somebody.
Biocapture surfaces produced for study of brain chemistry
December 13, 2007 12:24 PM - Penn State
A research team at Penn State has developed a novel method for attaching small molecules, such as neurotransmitters, to surfaces, which then are used to capture large biomolecules. By varying the identity and spacing of the tethered molecules, researchers can make the technique applicable to a wide range of bait molecules including drugs, chemical warfare agents, and environmental pollutants. Ultimately, the researchers also hope to identify synthetic biomolecules that recognize neurotransmitters so that they can fabricate extremely small biosensors to study neurotransmission in the living brain.
Researchers Double Cell Phone Memory

PASADENA, Calif. --Studies of the snap judgments we often make about people are shedding new light not only on social behavior, but also on drug abuse, gambling addiction, and other disorders in which our ability to make decisions is impaired, say scientists at the California Institute of Technology.
Managing manure in California
December 12, 2007 05:32 PM - Alec Rosenberg, UC Merced Newswire
Merced, California - A partnership between agricultural leaders and UC Merced aims to help California farmers maintain the environment and the economy.
California is the nation's leading dairy state, generating $5.2 billion in milk and cream sales a year. While that keeps the state's 1.7 million dairy cows busy making milk, they also produce plenty of manure. The manure is filled with nutrients that farmers can use as fertilizer, but it also can pollute the environment.
First face transplant worth the fuss, patient says

BOSTON (Reuters) - It took 18 months for her smile to come back completely, but doctors say the French woman who received the world's first partial face transplant is doing well and is very satisfied with the results.
Chemicals used as fire retardants could be harmful
December 12, 2007 05:02 PM - UC Riverside, Newswire
Riverside, California - Polybrominated diphenyl ethers (PBDEs), chemicals used as fire retardants, can be found in numerous items in the home, such as the television, computer, toaster and the sofa. Now, as reported in a news story days ago, they are being found in alarming concentrations, in human blood and breast milk – a potentially major concern for human health.
