| Patient selection for bilateral total knee replacement needs improvement Posted: 29 Sep 2012 11:04 AM PDT Because there are more risks with having a total knee replacement in both legs at the same time than having a knee replacement in one leg, doctors in recent years have been selecting younger and healthier patients for the bilateral procedure. Now a new study has revealed that although patients are younger and healthier than those undergoing only one-sided surgery, they are becoming sicker and some complication rates have risen.  |
| Potentially dangerous new malaria mosquito identified Posted: 29 Sep 2012 11:03 AM PDT Entomologists recently discovered a potentially dangerous new malaria-transmitting mosquito. The as yet unnamed, and previously unreported, mosquito breeds in the western areas of Kenya and has an unknown DNA match to any of the existing malaria-transmitting species.  |
| Sun unleashes a wide, but benign, coronal mass ejection Posted: 29 Sep 2012 11:03 AM PDT The sun erupted with a wide, Earth-directed coronal mass ejection on Sept. 27, 2012 at 10:25 p.m. EDT.  |
| New 'Green List' shows species on path to conservation success Posted: 29 Sep 2012 11:03 AM PDT The IUCN World Conservation Congress has adopted a motion to create a Green List to assess conservation success. The Green List for Species would include species identified as 'fully conserved,' which are those that exist in ecologically significant numbers, interacting fully with other species in their ecosystems.  |
| Time bomb: Military ordnance in Gulf of Mexico poses threat to shipping, says expert Posted: 29 Sep 2012 11:03 AM PDT Millions of pounds of unexploded bombs and other military ordnance that were dumped decades ago in the Gulf of Mexico, as well as off the coasts of both the Atlantic and Pacific oceans, could now pose serious threats to shipping lanes and the 4,000 oil and gas rigs in the Gulf, warns oceanographers.  |
| Posted: 29 Sep 2012 11:03 AM PDT Scientists have made the first observation of a predator avoidance behavior by a species of phytoplankton, a microscopic marine plant. The scientists made the unexpected observation while studying the interactions between phytoplankton and zooplankton.  |
| Clonal evolution in maxillary sinus carcinoma Posted: 29 Sep 2012 11:03 AM PDT Knowing how tumors evolve can lead to new treatments that could help prevent cancer from recurring, according to researchers. They have tracked several years of tumor evolution in a 47-year-old male patient with maxillary sinus carcinoma, a rare cancer of the sinus cavities beneath the cheeks that often requires surgical removal that is disfiguring.  |
| Therapy over the phone as effective as face-to-face, study suggests Posted: 29 Sep 2012 11:02 AM PDT A new study reveals that cognitive therapy over the phone is just as effective as meeting face-to-face.  |
| White shark diets vary with age and among individuals Posted: 29 Sep 2012 11:02 AM PDT White sharks, the largest predatory sharks in the ocean, are thought of as apex predators that feed primarily on seals and sea lions. But a new study shows surprising variability in the dietary preferences of individual sharks.  |
| New European statistics released on heart disease and stroke Posted: 29 Sep 2012 11:02 AM PDT New figures released to mark World Heart Day show a significant improvement in Europe's heart health. These figures represent the first comprehensive overview of the impact of cardiovascular disease since 2008.  |
| Lack of sleep leads to insulin resistance in teens Posted: 29 Sep 2012 11:02 AM PDT A new study suggests that increasing the amount of sleep that teenagers get could improve their insulin resistance and prevent the future onset of diabetes.  |
| Combination of targeted treatment drugs delays resistance in melanoma patients Posted: 29 Sep 2012 11:02 AM PDT Combined treatment with two drugs targeting different points in the same growth-factor pathway delayed the development of treatment resistance in patients with BRAF-positive metastatic malignant melanoma.  |
| Prostate cancer testing and treatment guidelines developed Posted: 29 Sep 2012 11:02 AM PDT New prostate cancer articles review and clarify recent updates made to the National Comprehensive Cancer Network's guidelines for the screening and treatment of prostate cancer.  |
