Some birds, at least, keep together on their migratory journeys, flying in tandem even when they are 200 meters or more apart.http://www.eurekalert.org/pub_releases/2008-07/uoia-bmt070708.php Whales and dolphins influence new wind turbine design- July 7, 2008 By studying the flippers, fins and tails of whales and dolphins, scientists have discovered some features of their structure that contradict long-held engineering theories. Dr. Frank Fish will talk about the exciting impact that these discoveries may have on traditional industrial designs including wind turbines and helicopters.http://www.eurekalert.org/pub_releases/2008-07/sfeb-wad070308.php Story tips from the Department of Energy's Oak Ridge National Laboratory, July 2008- July 7, 2008 Researchers have made the first mixed-oxide pellets from recycled spent nuclear fuel in a process that doesn't produce a separate plutonium stream. Tiny changes at the nanometer scale can have a colossal effect on the properties of a material, and for the first time researchers may have a method to see and even predict those changes. A new generation of electron microscope is helping scientists examine materials for fuel-efficient cars, superconductors, solar cells and other applications.http://www.eurekalert.org/pub_releases/2008-07/drnl-stf070708.php How can we overcome the barriers to treating drug-resistant TB- July 7, 2008 Almost 1 in 20 cases of tuberculosis worldwide is resistant to multiple drugs (known as multidrug-resistant TB or MDR-TB) and the World Health Organization has called for a massive scale up in public health efforts to tackle these cases. In this week's PLoS Medicine, a group of MDR-TB experts outlines its recommendations on conducting research that would help in the scale up.http://www.eurekalert.org/pub_releases/2008-07/plos-hcw070308.php Study shows rise in Cornwall's dolphin, whale and porpoise deaths- July 6, 2008 A study by the University of Exeter and Cornwall Wildlife Trust, published in the journal Biodiversity and Conservation, has revealed a disturbing rise in the number of whales, dolphins and porpoises found dead on Cornish beaches. The frequency of these mammals, collectively known as cetaceans, found stranded on beaches in Cornwall has increased with a sharp rise in the last eight years. After analyzing nearly 100 years of data, the researchers believe this could, in part, be due to more...http://www.eurekalert.org/pub_releases/2008-07/uoe-ssr070308.php UT Southwestern researchers identify new targets for RNAs that regulate genes- July 6, 2008 Tiny strands of genetic material called RNA -- a chemical cousin of DNA -- are emerging as major players in gene regulation, the process inside cells that drives all biology and that scientists seek to control in order to fight disease.http://www.eurekalert.org/pub_releases/2008-07/usmc-usr070208.php New treatment approach promising for lymphoma patients in the developing world- July 6, 2008 Preliminary results suggest that patients with aggressive non-Hodgkin's lymphoma in the developing world might benefit from a modified chemotherapy regimen, researchers say.http://www.eurekalert.org/pub_releases/2008-07/esfm-nta070208.php Counting tumor cells in blood predicts treatment benefit in prostate cancer- July 6, 2008 Counting the number of tumor cells circulating in the bloodstream of patients with castration-resistant prostate cancer can accurately predict how well they are responding to treatment, new results show.At the ESMO Conference Lugano organized by the European Society for Medical Oncology, researchers showed that changes in the number of circulating tumor cells predicted the outcome after chemotherapy in this hard to treat cancer.http://www.eurekalert.org/pub_releases/2008-07/esfm-ctc070208.php Herbal remedy reduces obesity and heart disease- July 6, 2008 Scientists from Germany have recently discovered that extracts of a traditional herbal remedy derived from Tabebuia impetiginosa can act to delay the absorption of dietary fat in animal models. They believe that the extract could be incorporated into a food supplement which may not only reduce obesity, but also lessen the risk of development of type 2 diabetes and coronary heart disease.http://www.eurekalert.org/pub_releases/2008-07/sfeb-hrr070408.php Treatment delays result in poor outcomes for men with breast cancer- July 6, 2008 Men who develop breast cancer are often not treated until the disease has spread to the point that treatment becomes difficult, new results show. Although most breast cancer patients are women, men make up roughly 1 percent of cases, Dr. Marina Garassino from the Orion Collaborative Group reports at the ESMO Conference Lugano, organized by the European Society for Medical Oncology.http://www.eurekalert.org/pub_releases/2008-07/esfm-tdr070208.php |
