Firefly Genes In Mice Allow Testing Of New Therapy Against Lymphoma
Researchers here have figured out a way to use a firefly gene to let them see just how effective a new drug combination actually is against some forms of cancer and its serious complication. The new study looked at ATLL, adult T cell lymphoma and leukemia, a form of cancer where it is particularly hard to gauge the disease's progress, and where the patients'prognosis is generally poor. There is now no widely effective therapy available to treat this disease successfully. Past Droughts Geographically Widespread In The West, According To Tree
When it's dry, it's dry all over, according to a new analysis of more than 400 years of annual streamflow in the Upper Colorado and Salt/Verde river basins. By using data from tree rings, University of Arizona researchers conclude that severe droughts and low-flow conditions in one basin are unlikely to be offset by abundant streamflow in the other basin. The study covers waterways from the states of Arizona, Colorado, New Mexico, Utah and Wyoming. UK Experts Develop Super-realistic Animation System
Computing experts at Cardiff University, UK, are developing a super-realistic animation system that simulates the movements of a face, based on speech. New Research Ties Harmless Viruses To Cancer
Research led by CSHL may link viruses that have been considered harmless to chromosomal instability and cancer. Science-based Teaching Tools On Underage Alcohol Use Under Development
Efforts to halt underage drinking often focus on peer pressure and the prevention of risky behaviors, but the American Association for the Advancement of Science is undertaking a new federally funded project to give middle-school children a science-based understanding of what can happen to them if they use alcohol. Frequent Yeast Infections May Be Linked To Certain Vaginal Bacteria Ec
The microbial ecosystem of the human vagina varies greatly among women. Those differences can lead to conditions that, if not diagnosed and treated correctly, may leave some women susceptible to a range of infections, including sexually transmitted diseases such as HIV. The research team compared the type of vaginal bacteria in a representative group of Caucasian and black women in North America. Three major findings emerged from the study: there are at least eight kinds of normal vaginal bacterial communities, each community is different, and, among the eight kinds of communities, some bacterial communities are unique to one or the other racial group. Halving Daily Cigarette Quota Has No Health Benefit
Halving the number of cigarettes smoked every day in the belief that it will stave off an early death makes no difference, suggests research in Tobacco Control. Although reducing consumption may have a place as a temporary measure in smoking cessation, this study proves quite clearly that the only safe way out of the risk caused by smoking is to quit, say the authors. Effective Treatment Found For Hepatitis C Patients With Low Blood-plat
For patients with hepatitis C, having a low blood platelet count is a frequent complication associated with advanced disease. This problem is compounded by the fact that standard antiviral treatment for the disease can further reduce platelet numbers to dangerously low levels, effectively denying these patients the treatment they urgently need. A new drug, eltrombopag, appears to significantly boost platelet counts, opening the door to effective treatment. Study Offers Innovative Profile Of Enzyme That Aids Tumor Growth
Using an innovative profiling strategy, scientists at the Scripps Research Institute have characterized an enzyme that is "highly elevated"in aggressive human tumor cells. When the enzyme, KIAA1363, was inactivated, it impaired tumor growth and migration in both ovarian and breast cancer cells, suggesting that inhibitors of this enzyme may prove valuable in the treatment of multiple types of cancer. Teens Delaying Sexual Activity; Using Contraception More Effectively
Sexual activity declined significantly for younger teenage girls and for teenage boys between 1995 and 2002, and teen contraceptive use improved in significant ways, according to a new study released today by the Department of Health and Human Services (HHS). The study compares new findings from the 2002 National Survey of Family Growth with the previous survey conducted in 1995.
