Coastal Retreat In Face Of Rising Sea Levels Found To Be Influenced By
The retreat of coastlines due to rising sea levels may be accelerated by wildfires, a Duke University researcher has discovered. In the absence of such fires, forests can slow the encroachment, he found. Faster Help For Avalanche Victims
Victims buried by an avalanche only have a chance of survival if they can be quickly and precisely located under the snow. A novel position-ing system, which will use the signals of Europe's future satellite system 'Galileo', is to help improve the search. It's the start of the skiing season: Attracted by bright sunshine and fresh snow, winter sports enthusiasts flock to the snow-covered slopes. But for some, the white splendor will prove fatal, especially for those who wander off the regular slope. Researchers Discover Method In Mice To Restore Tamoxifen Sensitivity I
The widely used breast cancer drug tamoxifen (Nolvadex®), which can become less effective over time, might retain its full strength indefinitely if used along with a second drug, according to new research in mice conducted by investigators from the National Cancer Institute (NCI), part of the National Institutes of Health, and their partners. The results appear in the December 11, 2006, issue of Cancer Cell. Salt Intake Is Strongly Associated With Obesity
The study reports that increasing intakes of sodium (salt) obligatorily produce a progressive increase in thirst. The progressive increase in the average intake of salt explains the observed concomitant increase in the intake of beverages which, in turn, has caused a marked net increase in the intake of calories during the same period in the United States. [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." Global Climate Change: The Impact Of El Niño On Galápagos Marine Iguan
A before-and-after study led by Yale biologists, of the effects of 1997 El Niño on the genetic diversity of marine iguanas on the Galápagos Islands, emphasizes the importance of studying populations over time and the need to determine which environmental and biological factors make specific populations more vulnerable than others. Nanotube Adhesive Sticks Better Than A Gecko's Foot
Mimicking the agile gecko, with its uncanny ability to run up walls and across ceilings, has long been a goal of materials scientists. Researchers have now taken one sticky step in the right direction, creating synthetic "gecko tape"with four times the sticking power of the real thing. Hairs, Fibers, Crime, and Evidence: Part 1: Hair Evidence
Explains how human and animal hairs are examined as crime scene evidence by a forensics laboratory. Discusses hair microscopy, hair anatomy and growth, determination of the body area from which a hair originated and the racial group associated with the hair, and related topics. Includes images. From the Federal Bureau of Investigation (FBI), Trace Evidence Unit. Langerhans Cells Regulate Immune Reactions In The Skin
Researchers at Yale School of Medicine have demonstrated that Langerhans cells in the skin, which had been thought to alert the immune system to pathogens, instead dampen the skin's reaction to infection and inflammation. No Single Gene For Eye Color, Researchers Prove
A study by researchers from The University of Queensland's Institute for Molecular Bioscience (IMB) and the Queensland Institute of Medical Research is the first to prove conclusively that there is no single gene for eye colour. Instead, it found that several genes determine the colour of an individual's eyes, although some have more influence than others.
