Blood Transfusions May Be Harmful To Some Patients
Heart attack patients in the U.S. are far more likely to receive a blood transfusion than patients in other countries with the very same condition, but the outcome of their treatment is no better. Increasing evidence suggests transfusions may not only be unnecessary but may actually be harmful to some patients. Incorporating biofunctionality into nanomaterials for medical, environ
Researchers have discovered how to use atomic layer deposition to incorporate "biological functionality" into complex nanomaterials, which could lead to a new generation of medical and environmental health applications. For example, the researchers show how the technology can be used to develop effective, low-cost water purification devices that could be used in developing countries. NASA Prepares For Performing New Science On The Moon
NASA has selected proposals, including two from the Jet Propulsion Laboratory in Pasadena, Calif., for future lunar science activities. In addition, the agency has established two new programs that will enhance research made possible by the Vision for Space Exploration. The proposals and programs are part of an effort by NASA to develop new opportunities to conduct important science investigations during the planned renewal of human exploration of the moon. Dead Men Do Tell Tales: Strange Burial Positions Show Pacific Island L
Archaeologists analysed skeletons'teeth from seventeen excavated skeletons who were found in some unusual burial positions at the earliest ancient cemetery in the Pacific. The scientists identified a small group of immigrants, mostly buried with the head to the south, and one with three heads on his chest. Vanishing Beetle Horns Have Surprise Function
The function of horned beetles' wild protrusions has been a matter of some consternation for biologists. Digging seemed plausible; combat and mate selection, more likely. Even Charles Darwin once weighed in on the matter, suggesting -- one imagines with some frustration -- the horns were merely ornamental. In this month's American Naturalist (Dec. 2006) and the Nov. 2006 issue of Evolution, Indiana University Bloomington scientists present an entirely new function for the horns: during their development, Onthophagus horned beetles use their young horns as a sort of can opener, helping them bust out of thick larval shells. Some Brain Cells 'Change Channels' To Fine-tune The Message
Johns Hopkins researchers have identified the proteins that allow specific brain cells to "change channels,"a rare ability that tweaks what can come into the cell. The findings, described in the March 24 issue of Neuron, may let researchers harness the process, perhaps one day using it to protect cells that die in Lou Gehrig's disease. PGA On A Tour Under The Skin
In their study appearing online on February 3 in advance of publication in the March 1 print edition of the Journal of Clinical Investigation, Michael Otto and colleagues from Rocky Mountain Laboratories demonstrate that S. epidermidis secretes an extracellular polymer called poly-gamma-glutamate (PGA) to facilitate growth and ensure survival of the bacteria inside the human host. Never Lose Luggage Again
RFID tags promise to all but eliminate the annoyance of misrouted luggage at a time when more bags go missing than ever. But at up to 20 cents a bag, airlines aren't racing to the solution. By Dave Demerjian. Creeping Crinoids! Sea Lilies Crawl To Escape Predators, New Video Sho
With their long stalks and feathery arms, marine animals known as sea lilies look a lot like their garden-variety namesakes. Perhaps because of that resemblance, scientists had always assumed that sea lilies stayed rooted instead of moving around like their stalkless relatives, the feather stars. Vitamin D May Reduce Falls In Elderly Nursing Home Residents
New research suggests that reducing the number of falls suffered by seniors in nursing homes may be helped by taking a vitamin, along with other measures known to decrease falls. According to a study in Journal of the American Geriatrics Society, seniors taking a high daily dose of vitamin D experienced 72 percent fewer falls compared to those taking a placebo.
