| Strategy For Mismatched Stem Cell Transplants Triggers Protection Against Graft-vs.-host Disease
October 8, 2009 at 11:00 pm
|
| A technique being tested in stem cell transplants from imperfectly matched donors has revealed an unforeseen response that can suppress graft-versus-host disease. The previously unrecognized specificity of regulatory T cells helps explain why the patients treated with the new strategy -- known as "co-stimulatory blockade" -- have shown a low level of GVHD. The findings suggest that the technique might prove valuable in solid organ transplants, as well as in treating autoimmune disease. |

| African American Lung Cancer Patients May Have Different Response To New Cancer-fighting Drugs
October 8, 2009 at 11:00 pm
|
| Clinical research has found that African Americans with a common form of lung cancer have a lower frequency of drug-sensitizing genetic mutations, which may impact response to new cancer-fighting drugs. A new study has found that ethnicity plays a significant role in non-small cell lung cancer (NSCLC) genetics and more personalized treatments may be beneficial to cancer patients. |
| Nitrogen Deposition Limits Climate Change Impacts On Carbon Sequestration
October 8, 2009 at 11:00 pm
|
| The role of the forests is assumed to increase in the future, as an important buffer of climate change and increasing carbon dioxide concentrations. So-called Earth system models, computer systems making predictions for the globe, estimate that this effect can be very large. However, new research results, based on measurements at hundreds of European forests, indicate that predicted effects by these models are overestimated because they ignore the limitation of nitrogen. It makes the current predictions by Earth system models more than twice as high as they most likely will be. |
| Study Examines Ethical Dilemmas Of Medical Tourism
October 8, 2009 at 11:00 pm
|
| Medical tourism in Latin America needs to be regulated to protect consumers, according to researchers.

| Unnatural Selection: Birth Control Pills May Alter Choice Of Partners
October 8, 2009 at 11:00 am
|
| Is it possible that the use of oral contraceptives is interfering with a woman's ability to choose, compete for and retain her preferred mate? A new paper reviews emerging evidence suggesting that contraceptive methods which alter a woman's natural hormonal cycles may have an underappreciated impact on choice of partners for both women and men and, possibly, reproductive success. |
| NASA Refines Asteroid Apophis' Path Toward Earth
October 8, 2009 at 8:00 am
|
| Using updated information, NASA scientists have recalculated the path of a large asteroid. The refined path indicates a significantly reduced likelihood of a hazardous encounter with Earth in 2036. Initially, Apophis was thought to have a 2.7 percent chance of impacting Earth in 2029. Additional observations of the asteriod ruled out any possibility of an impact in 2029. However, the asteroid is expected to make a record-setting -- but harmless -- close approach to Earth on Friday, April 13, 2029, when it comes no closer than 29,450 kilometers (18,300 miles) above Earth's surface. |
| New Link Found Between Osteoporosis And Celiac Disease

| Large-Scale Cousin Of Elusive 'Magnetic Monopoles' Found At NIST
October 8, 2009 at 5:00 am
|
| Any child can tell you that a magnet has a "north" and a "south" pole, and that if you break it into two pieces, you invariably get two smaller magnets with two poles of their own. But scientists have spent the better part of the last eight decades trying to find, in essence, a magnet with only one pole. A team working at the National Institute of Standards and Technology (NIST) has found one. |
| New Approach For Growing Bone To Fight Osteoporosis And Other Diseases

| Injury And Hazards In Home Health Care Nursing Are A Growing Concern
October 8, 2009 at 5:00 am
|
| Patients continue to enter home health care "sicker and quicker," often with complex health problems that may require extensive nursing care. This increases the risk of needlestick injuries in home health care nurses. In a recent study, the rate of needlestick-type injuries was 7.6 per 100 nurses. At this rate, the scientists estimate that there are nearly 10,000 such injuries each year in home care nurses. |
