There is good news for the 27,000 plus people around the world who donate a kidney each year. A study which followed living kidney donors for 10 years found that they were at no greater risk for heart disease than the healthy general population.
Treatment with vitamin D reduced the size of uterine fibroids in laboratory rats predisposed to developing the benign tumors, reported researchers funded by the National Institutes of Health. Uterine fibroids are the most common noncancerous tumors in women of childbearing age. Fibroids grow with...
Indiana University biologists have found that specific types of RNA polymerase enzymes, the molecular machines that convert DNA into RNA, can differ in function based on variation in the parts -- in this case protein subunits -- used to assemble those machines.
More than 70 years after the first sulfa drugs helped to revolutionize medical care and save millions of lives, St. Jude Children's Research Hospital scientists have determined at an atomic level the mechanism these medications use to kill bacteria. The discovery provides the basis for a new generat...
Cut marks found on Ice Age bones indicate that humans in Ohio hunted or scavenged animal meat earlier than previously known. Dr. Brian Redmond, curator of archaeology at The Cleveland Museum of Natural History, was lead author on research published in the Feb. 22, 2012 online issue of the journal Wo...
At some point this year, after NASA's rover Curiosity has landed on Mars, a laser will fire a beam of infrared light at a rock or soil sample. This will "ablate" or vaporize a microgram-sized piece of the target, generating a plume of ionized gas or plasma, which will be analyzed by spectrometers to...
A team of 18 researchers at Moffitt Cancer Center in Tampa, Fla., have found that treating high-risk, soft tissue sarcoma patients with a combination of implanted dendritic cells (immune system cells) and fractionated external beam radiation (EBRT) provided more than 50 percent of their trial patien...
Researchers at the University of Illinois at Chicago College of Medicine have found that a molecule found at elevated levels in cancer cells seems to protect them from the "cell-suicide" that is usually triggered by chemotherapy or radiation.
The majestic leatherback turtle is the largest sea turtle in the world, growing to more than 6 feet in length. It is also one of the most threatened. A major new study of migration patterns has identified high-use areas—potential danger zones—in the Pacific Ocean for this critically en...
Whenever we are doing something, one of our brain hemispheres is more active than the other one. However, some tasks are only solvable with both sides working together. PD Dr. Martina Manns and Juliane Römling of the Ruhr-Universität Bochum are investigating, how such specializations and co-op...
Particles from comet 81P/Wild 2 brought to Earth in 2006 by NASA's Stardust spacecraft indicate that Jupiter formed more than three million years after the formation of the first solids in our Solar System. The new finding helps test Solar System formation theories, which do not agree on the timing ...
Working in the emerging field of systems biology, UT Southwestern Medical Center researchers mathematically predicted how bacteria that cause food poisoning hijack a cell's sense of direction and then confirmed those predictions in living cells.
