Unusual Material That Contracts When Heated Is Giving Up Its Secrets T
Most solids expand when heated, a familiar phenomenon with many practical implications. Among the rare exceptions to this rule, the compound zirconium tungstate stands out by virtue of the enormous temperature range over which it exhibits so-called "negative thermal expansion,"contracting as it heats up and expanding as it cools, and because it does so uniformly in all directions. Designer Molecule Detects Tiny Amounts Of Cyanide, Then Glows
A small molecule designed to detect cyanide in water samples works quickly, is easy to use, and glows under ultraviolet or "black" light. Although the fluorescent molecule is not yet ready for market, its creators report that the tool is already able to sense cyanide below the toxicity threshold established by the World Health Organization.

Green tea appears to protect against cancer by affecting a "promiscuous"protein that pharmaceutical experts are already targeting in an effort to develop a new drug to stop the disease, scientists have found. Supersolids -- Can Atoms Unify And Flow Without Resistance?
Imagine you have an orchestra together, but everyone is playing their own tune, until they begin to follow a conductor. In a normal solid, every atom has its own behavior until very close to absolute zero. Then quantum mechanics takes over and dictates everyone to play the same tune. Gene Therapy For Parkinson's Hitches Ride On Virus
A new clinical trial is examining whether therapeutic genes that hitch a ride with a harmless virus attracted to nerve cells can reduce Parkinson's disease symptoms. The year-long trial involves pairing an inactive virus known as AAV2 with a gene that causes nerve cells to produce neurturin, a protein that may improve the function of dopamine-producing cells and protect them against damage. 'Missing Link' In Process Leading To Alzheimer's Disease Identified
Scientists at the University of Virginia have identified what appears to be a major missing link in the process that destroys nerve cells in Alzheimer's disease, an incurable disease that slowly destroys memory and cognitive abilities. The findings are reported in the Nov. 20, 2006, issue of the Journal of Cell Biology and could eventually lead to new drugs that target and disrupt specific proteins that conspire in the brain to cause Alzheimer's. Kids Of Depressed Moms More Prone To Behavioral Problems And Injury
Young children whose mothers are depressed are more prone to behavioral problems and injury, suggests new research. For every 1 point increase on the depression score, the risk of injury rose by 4% and the risk of behavioral problems increased by 6%. [Odd] A Romanian couple has named their son Yahoo as a sign of gratitu
Daily Libertatea said on Thursday Cornelia and Nonu Dragoman, both from Transylvania, met and decided they were meant for each other following a three-month relationship over the net.They married and had a baby this Christmas, whom they decided to name after one of the worldwide web's most popular portals."We named him Lucian Yahoo after my father and the net, the main beacon of my life,"Cornelia Dragoman was quoted as saying. Double heart trouble
US researchers have demonstrated that MRI is twice as sensitive as other techniques at detecting early heart damage in patients with the immune system disorder sarcoidosis. The early detection of heart problems in patients with sarcoidosis is imperative if the risk of dying from heart failure is to be reduced for such patients. Sarcoidosis is [...]
