Penn Study Points To How COX-2 Inhibitors Can Eventually Lead To Heart
University of Pennsylvania School of Medicine researchers have found additional evidence that may help explain how selective inhibitors of COX-2 might predispose individuals to heart disease and stroke. In Circulation Research, they report that a COX-2-derived fatty substance -- a prostaglandin called prostacyclin -- controls the blood-vessel response to stresses such as high-blood pressure, thereby further linking COX-2 inhibitors to an increased risk of heart attack or stroke. [Ironic] LONDON: A jailed cocaine dealer is working as Santa Claus on
John Tams, who dons beard, boots and red suit to work in a cafe's Christmas grotto, said he wanted to give something back to the community... Faster, More Cost-effective DNA Test For Crime Scenes, Disease Diagnos
Scientists in Japan are reporting development of a faster, less expensive version of the fabled polymerase chain reaction, a DNA test widely used in criminal investigations, disease diagnosis, biological research and other applications. The new method could lead to expanded use of PCR in medicine, the criminal justice system and elsewhere, the researchers say. DNA-scanning Technology Finds Possible Sites Of Cancer Genes In Chromo
With equipment designed to probe the smallest segments of the genetic code, researchers at Dana-Farber Cancer Institute and collaborating institutions have found something much larger: sections of the chromosomes of lung cancer cells where cancer-related genes may lurk. Decline In Blood Platelet Count Associated With Increased Risk Of HIV-
HIV patients with declining platelet counts appear to be at increased risk for HIV--associated dementia, according to a new article. Identifying biological markers for the development of HIV--associated dementia is critical both for diagnosing the disorder and for understanding its underlying mechanisms. Gender divide in children's use of cell phone features, study finds
A recent sociological study finds that the way the kids will use their new phones depends on their gender. United Nations Framework Convention on Climate Change (UNFCCC)
The United Nations maintains this website "to support arrangements for meetings organized under the [Climate Change] Convention, [and] to transmit official documents and reports. ... It also serves the Kyoto Protocol."Features background about climate change science and what can be done, discussion of methodologies and tools to evaluate global warming impacts, reports and data (such as greenhouse gas emissions data), and related material. Fossil Whale Puts Limit On Origin Of Oily, Buoyant Bones In Whales
When a whale dies and falls to the bottom in the deep ocean, it attracts a weird community of mollusks, crabs and worms that feed on its oil-rich bones. A 15 million-year-old fossilized whale discovered on Aņo Nuevo Island is the first fossil whale fall discovered in California, and one of the youngest and most complete fossil whale falls ever found. It shows that whale-fall organisms look for oily bones rather than large whale carcasses. Scientists Release Audio Sent By Huygens During Titan Descent
Scientists have produced an audio soundbite that captures what the Cassini orbiter heard from Huygens as the probe descended on Titan on Jan. 14. The sounds may not be music to everyone's ears, but they're beautiful, interesting and important to investigators who are reconstructing the probe's exact position and orientation throughout its parachute dive to Titan's surface. Antagonistic genes control rice growth
Scientists have found that a plant steroid prompts two genes to battle each other -- one suppresses the other to ensure that leaves grow normally in rice and the experimental plant Arabidopsis thaliana, a relative of mustard. The results have important implications for understanding how to manipulate crop growth and yield.
