Automated System Installs Pavement Markers On rainy nights in Georgia and across the nation, drivers greatly benefit from small, reflective markers that make roadway lanes more visible. A new automated system for installing the markers is expected to improve safety for workers and drivers. Milk thistle herb protects cancer patients from chemotherapy-associate A new study finds that the herb milk thistle may help treat liver inflammation in cancer patients who receive chemotherapy. The study indicates that the herb could allow patients to take potent doses of chemotherapy without damaging their liver. Helper T Cell's Effect Raises Possibility Of Cellular Therapy, Vaccine A specific type of T helper cell awakens the immune system to the stealthy threat of cancer and triggers an attack of killer T cells custom-made to destroy the tumors, scientists report. Katrina and the Waves The floodwaters that inundated New Orleans after Hurricane Katrina were not as toxic to humans as previously thought. The findings published by researchers at Louisiana State University are good news for those who were exposed directly to the floodwaters, although say nothing of the physical devastation caused by the flood. Methane Bubbling From Arctic Lakes, Now And At End Of Last Ice Age Scientists have now identified a new likely source of a spike in atmospheric methane coming out of the North during the end of the last ice age. Methane bubbling from arctic lakes could have been responsible for up to 87 percent of that methane spike, said researchers. The findings could help scientists understand how current warming might affect atmospheric levels of methane, a gas that is thought to contribute to climate change. Researchers Demonstrate NEXRAD Radar Helps National Weather Service Fo Tornado warnings have improved significantly and the number of tornado casualties has decreased by nearly half since a network of Doppler weather radars were installed nationwide by the National Oceanic and Atmospheric Administration's National Weather Service a decade ago, according to a study published in the June issue of Weather and Forecasting, a journal of the American Meteorological Society. Teaching Adolescents About Condoms Teaching adolescents to use condoms when abstinence fails is a reasonable strategy for preventing HIV, according to a new article. This finding might appear common sense, but the best way to teach HIV prevention to young people has in fact has been controversial. The "abstinence-only"approach, favored in recent years by US government-sponsored programs, reflects the notion that teaching adolescents anything about safer sex (including condom use) might encourage risky activity. However, recent studies have found that abstinence-only programs have failed to reduce HIV risk. Marijuana Use Causes Early Pregnancy Failure Vanderbilt University researchers have shown that exposure to tetrahydrocannabinol, the major psychoactive component of marijuana, at the time of conception and early in pregnancy prevents embryos' safe passage from the ovary to the uterus, resulting in early pregnancy failure in mice. The study appears in the August issue of the Journal of Clinical Investigation. As such, the use of THC-containing drugs such as marijuana may lead to ectopic pregnancy and/or impaired fertility in women. High School Gear for the Gossip Girl Set Accept your inner Gossip Girl with gear even Blair Waldorf would love.
