Researchers at Rush-Presbyterian-St. Luke’s Medical Center, Chicago, and Lausanne, Switzerland, have successfully used gene therapy to reverse the anatomical, cellular changes that occur in the brains of primates with Parkinson’s disease. The researchers also report success in preventing the disease from progressing and reversing functional deficits or symptoms associated with the disease in monkeys displaying […]
A research team from Massachusetts General Hospital (MGH) has shown that the majority of HIV-infected individuals who begin antiviral therapy during the earliest stages of their infection eventually can stop taking drugs and keep the virus under control with their immune systems alone. In the study reported in the Sept 28 issue of Nature, a […]
Listen up expectant dads: All those hours spent talking to your unborn child via your partner’s burgeoning belly don’t go unnoticed. New research from Queen’s Faculty of Health Science proves that at 30 weeks the fetus is indeed able to hear and just might be listening to your muffled words of love. Dr. Barbara Kisilevsky […]
Vaccines designed to trigger an immune response to a small HIV protein called Tat could be a promising way to fend off the virus, intriguing new data suggest. According to a report in this week’s journal Nature, “killer” T cells targeted to the Tat protein can effectively contain simian immunodeficiency virus (SIV), the monkey version […]
Ice cores drilled through a glacier more than four miles up in the Himalayan Mountains have yielded a highly detailed record of the last 1,000 years of earth’s climate in the high Tibetan Plateau. Based on an analysis of the ice, both the last decade and the last 50 years were the warmest in 1,000 […]
How well your lungs function may predict how long you live. This finding is the result of a nearly 30-year follow-up of the association between impaired pulmonary function and all causes of mortality, conducted by researchers at the University at Buffalo. Results of the study appear in the September issue of Chest. The UB researchers […]
A 150-year record of freeze and ice breakup dates for lakes and rivers in such far-flung locales as Wisconsin and Japan chronicles a recent climate warming trend in the Northern Hemisphere, say researchers in the 8 September issue of the international journal Science. The study, conducted by an international research team and led by John […]
A chemical analysis of a rare, uncontaminated 4.5 billion-year-old meteorite that fell to Earth earlier this year shows that its composition sets it apart from other meteorites found on Earth, giving scientists a glimpse of the solar system that has not been seen before. The findings, when added to other studies of the meteorite, may […]
“There is nothing like sport to improve your breathing!” people often say. Yet this is one piece of advice many top athletes must wish they never listened to, as there is no longer any doubt that an alarming proportion of them experience quite the opposite effect: too much training is actually bad for their breathing. […]
In a collaborative effort, scientists have for the first time successfully increased normal life span in the nematode worm C. elegans through the use of drugs that augment the organism’s natural antioxidant systems. As reported in the September 1, 2000 issue of Science, it appears that oxidative stress is a major determinant of life span […]
