About one-half percent of patients undergoing facelift surgery at one outpatient surgical center between 2001 and 2007 developed methicillin-resistant Staphylococcus aureus infections, according to a new report.
Using the Canadian Light Source synchrotron, researchers have determined the detailed structure of the enzyme the Norwalk virus uses to make copies of its genetic code in order to replicate itself. The information is crucial to developing drugs that could be used to treat outbreaks of Norwalk and other related viruses.
Lyme disease is the blight of countryside users but it may be prevented with a single injection, according to research in the Journal of Medical Microbiology. Researchers found that a new formulation that is programmed to release the anti-Lyme disease drug over a 20 day period was 100% effective.
Chemical engineers have discovered a new way to control the motion of fluid particles through tiny channels, potentially aiding the development of micro- and nano-scale technologies such as drug delivery devices, chemical and biological sensors, and components for miniaturized biological "lab-on-a-chip" applications.
Young girls who are hyperactive are more likely to get hooked on smoking, under-perform in school or jobs and gravitate towards mentally abusive relationships as adults, according to a new study.
Some 15 chimpanzees facing extinction in an isolated Rwandan forest have a greater chance for survival thanks to one of Africa's most ambitious forest restoration efforts ever. A 30-mile (50km) tree corridor will be planted to connect the Gishwati Forest Reserve, the chimpanzees' home range, to Nyungwe National Park.
Researchers have created a robot, designed to help users with limited mobility with everyday tasks, that moves autonomously to an item selected with a green laser pointer, picks up the item and then delivers it to the user, another person or a selected location such as a table. The new robotic communication method may help robots find their way into the home sooner.
A compound present naturally in grape skin,resveratrol, can protect against the cellular damage to blood vessels caused by high production of glucose in diabetes, according to an article in the science journal "Diabetes, Obesity and Metabolism." Resveratrol stops the damage by helping cells make protective enzymes to prevent the leakage of electrons and the production of toxic 'free radicals'.
Rheumatoid arthritis patients who eat a gluten-free vegan diet could be better protected against heart attacks and stroke. RA is a major risk factor for these cardiovascular diseases, but a gluten-free vegan diet was shown to lower cholesterol, low-density lipoprotein and oxidizedLDL, as well as raising the levels of natural antibodies against the damaging compounds in the body that cause symptoms of the chronic inflammatory disease rheumatoid arthritis, such as phosphorylcholine.
Approximately 25 percent of breast cancer survivors experience mild to moderate memory, concentration and cognitive problems known as "chemobrain". A new study has documented the extent of changes to the brain's white matter in women who received chemotherapy for breast cancer.
HOUSTON (Reuters) - Astronauts aboard the International Space Station prepared for a spacewalk on Thursday to test a heat shield repair technique and replace a failed circuit breaker.
WASHINGTON (Reuters) - The shooting apart of a crippled U.S. spy satellite last month created no significant new space debris, with all but small bits burning on re-entry to the atmosphere, the mission commander said Wednesday.
WASHINGTON (Reuters) - An organic molecule has been spotted for the first time in the atmosphere of a planet outside our solar system, a key step toward possibly finding signs of life on a distant world, scientists said.
