Astrobiology Magazine
This online magazine focuses on the search for life elsewhere in the universe. Features news stories, interviews, a "Great Debates"series, "Hot Topics"(such as Titan, Europa, and new planets), image galleries, and more. Includes archives back to 2000. Also available in Spanish.

Some 119 million years ago, large portions of the world ocean were close to suffocation. The reason: acute lack of oxygen. This is documented by geological findings around the world. The exact timing and the causes of this so-called oceanic anoxic event however, are not known yet: How fast did it happen, and why? How much time did the ocean system need to recover? Geologists are seeking to find out with the help of high quality sediment cores from southern France. The obtained data could also be relevant for future climate scenarios. New Gas Sensors Patterned With Conducting Polymer
An improved method for depositing nanoporous, conducting polymer films on miniaturized device features has been demonstrated by researchers at the National Institute of Standards and Technology (NIST). Described in the April 6 issue of the Journal of the American Chemical Society,* the method may be useful as a general technique for reproducibly fabricating microdevices such as sensors for detecting toxic chemicals. Perceived Discrimination Linked To Coronary Artery Calcification
The more discrimination African-American women report, the more likely they are to have coronary artery calcification, a buildup of calcium in the vessels that is associated with atherosclerosis. [Obvious] Chicago Tribune Pulls 'Vulgar' Section
A preprinted section was pulled from Wednesday's Chicago Tribune because it contained an article discussing the use of a vulgar slang term in referring to women, according to the newspaper. Lower Metabolism, Eating Behavior Possibly Explain The Cause Of Overwe
A lower metabolism, as well as slight changes in eating behavior, could explain the positive energy balance leading to being overweight in narcolepsy. Narcolepsy is a sleep disorder that causes people to fall asleep uncontrollably during the day. It also includes features of dreaming that occur while awake. Other common symptoms include sleep paralysis, hallucinations and cataplexy. National Domestic Violence Hotline (NDVH)
"NDVH is a nonprofit organization that provides crisis intervention, information and referral to victims of domestic violence, perpetrators, friends and families. The Hotline answers a variety of calls and is a resource for domestic violence advocates, government officials, law enforcement agencies and the general public."Website includes fact sheets, statistics about domestic violence in the U.S., and links to related sites. In English and Spanish. NDVH is a project of Texas Council on Family Violence. Carnegie Mellon Scientist Develops Way To Deliver Promising Genetic To
By exploiting an HIV protein that readily traverses cell membranes, Carnegie Mellon University scientists have developed a new way to introduce a gene-like molecule called a peptide nucleic acid (PNA) directly into live mammalian cells, including human embryonic stem (ES) cells. The work, published online December 2 in Chemical Communications, holds considerable promise in genetic engineering, diagnostics and therapeutics. Study Points Way To Communicating Nanotech
With consumer applications in everything from clothing, personal-care products and sporting goods to air purification systems, computers and home appliances, nanotechnology rapidly is becoming an integral part of everyday life. Yet survey results show that public audiences largely lack awareness and understanding of nanotechnology concepts, says Olivia Castellini, a former postdoctoral researcher with the University of Wisconsin-Madison Materials Research Science and Engineering Center (MRSEC) Interdisciplinary Education Group. Cold Sore Virus Might Play Role In Alzheimer's
A gene known to be a major risk factor for Alzheimer's disease puts out the welcome mat for the virus that causes cold sores, allowing the virus to be more active in the brain compared to other forms of the gene. The findings add some scientific heft to the idea, long suspected by some scientists, that herpes somehow plays a role in bringing about Alzheimer's disease.
