Genes That Increase Rheumatoid Arthritis Risk Identified
A genetic region that is associated with increased risk of rheumatoid arthritis has been identified. The disease is a chronic and debilitating inflammatory disease of the joints that affects an estimated 2.1 million Americans. The hope is that by learning more about the genes and their role in the disease, scientists may find clues to influencing treatment of the disease. How A Close Bond Activates The Immune System
The communication between immune cells hasn't been well understood because scientists had no suitable techniques to manipulate it. Now that problem has been solved. In a new study scientists at New York University School of Medicine and the University of California, Berkeley, report that they have observed the exchange of information between immune cells that is required to spark a body wide response to infection. Piddling Fish Face Off Threat Of Competition
Aggressive territorial male Mozambique tilapia fish send chemical messages to rival males via their urine. They increase urination, have smellier urine and store more in their bladders than less aggressive males, according to new research. Vitamin C And Water Not Just Healthy For People -- Healthy For Plastic
Two new laboratory breakthroughs are poised to dramatically improve how plastics are made by assembling molecular chains more quickly and with less waste. Using such environmentally friendly substances as vitamin C or pure water, the two approaches present attractive alternatives to the common plastic manufacturing technique called free radical polymerization (FRP). [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... Muscle Puzzle
Muscles and myosin - Read the hree part feature from David Bradley Science Writer Single Genetic Defect Produces Specific Cognitive Deficit In Mice
Researchers have found that, in mice, producing a single genetic defect in a molecule that "reloads"neurons to trigger one another using the neurotransmitter acetylcholine impairs the mice's ability to recognize objects or other mice. [Scary] Pregnant woman says 'maternal instinct' helped her kill attack
FORT MITCHELL, Ky. - A pregnant woman who killed her attacker said a maternal instinct helped her fight off the woman who investigators believe was after her unborn child."I do believe that I fought harder because it was for my child,"Sarah Brady told ABC's "Good Morning America"in interviews aired Sunday and Monday. "It is a maternal instinct to protect your child to the very end."Katherine Smith, 22, died Thursday after luring Brady to her apartment to pick up a package supposedly delivered to the wrong address. When Smith pulled out a knife and attacked the pregnant woman, Brady fought back, striking Smith on the head with an ash tray and stabbing her three times with her own knife, police said. Brady, 26, said she didn't know Smith before the two met at Smith's apartment and can't be certain why Smith wanted to kill her."I really am not sure what was going through her mind,"Brady told ABC. "The only thing I thought was that she was going to kill me and my child and that is the only thing that ran through my mind." New Hope For Regenerative Medicine: Hematopoietic Reconstitution With
In the February 15th issue of Genes &Development, Dr. K. John McLaughlin and colleagues report on their success in using uniparental embryonic stem cells to replace blood stem cells in mice. Uniparental embryonic stem cells are an appealing alternative source of patient-derived embryonic stem cells, as they have several advantages over embryonic stem cell lines generated by somatic cell nuclear transfer (also known as therapeutic cloning). Study Shows Deer In Chronic Wasting Disease Zone Stick To Home
White-tailed deer, it seems, are homebodies. That is the upshot of an intensive study of the traveling behaviors of 173 radio-collared white-tailed deer in south central Wisconsin. The new results may help researchers and wildlife managers better understand how chronic wasting disease (CWD) spreads.
