PET And Bioluminescent Imaging Aid Evaluation Of Stem Cells'Potential
Using positron emission tomography imaging with bioluminescence -- the light produced by a chemical reaction within an organism -- researchers are starting to understand the behavior of transplanted or implanted stem cells that may one day be used to develop new treatments for disease. What Is The Effect Of Using Nicotine Patches During Pregnancy?
In the most extensive trial of its kind, 1050 pregnant women are being recruited to establish the effect of using nicotine patches during pregnancy. The £1.3m clinical trial -- Smoking, Nicotine and Pregnancy (SNAP) trial -- will investigate whether nicotine replacement therapy (NRT) is safe, effective and cost-effective for mums-to-be who want to give up smoking. It will also study the effect on the behaviour and development of the child. Federal Cyber Service: Scholarship for Service (SFS)

This program provides scholarships that fully fund"typical students costs while attending an approved institution of higher education. Features an FAQ for students and a list of participating institutions. From the U.S. Office of Personnel Management.
New Method For Imaging Dec. 26 Indian Ocean Earthquake Yields Unpreced
Scientists at Scripps Institution of Oceanography at UCSD and their colleagues at UCLA have developed a new method for imaging how the earth ruptured during the massive Dec. 26 Indian Ocean earthquake. In this method, the scientists use the first-arriving seismic waves generated by an earthquake to produce detailed images within 30 minutes of an event, a development that could have implications for public-warning and tsunami-alert systems. Vaccine Against Malaria Will Reduce Disease, Study Suggests
Researchers have just published data potentially impacting the three billion people exposed to malaria every year. Novel findings show that new antibodies inhibit infection by the Plasmodium vivax (P. vivax) malaria parasite. Low Heart Rate Variability In Depressed Patients Contributes To High M
Scientists have known for years that depression increases the risk of dying in the months after a heart attack, but they haven't understood how depression raises that risk. Now, behavioral medicine specialists at Washington University School of Medicine in St. Louis, report in the Archives of Internal Medicine that abnormal heart rate variability is partially responsible for depression's effects in heart patients. Safety and Health Topics: Benzene
Workplace safety information related to benzene, an "aromatic hydrocarbon that is produced by the burning of natural products. It is a component of products derived from coal and petroleum and is found in gasoline and other fuels."Discusses OSHA standards and health effects from exposure to benzene, which has been shown "to be a carcinogen (cancer-causing)."From the Occupational Safety &Health Administration (OSHA). White Collar Proteins Help Fungi Do It In The Dark
Two genes controlling light responses - BWC1 and BWC2 - were identified and shown to regulate development and virulence of the fungal pathogen Cryptococcus neoformans. U.S. Food and Drug Administration: Recalls, Market Withdrawals, and Sa
The U.S. Food and Drug Administration (FDA) provides information about "the most significant product actions of the last 60 days, based on the extent of distribution and the degree of health risk. The recalls on the list are mainly Class I [reasonable probability that the use of or exposure to product will cause serious adverse health consequences]."Products include food, drugs, and medical devices.
