| Bird-from-dinosaur theory of evolution challenged: Was it the other way around? A new study provides yet more evidence that birds did not descend from ground-dwelling theropod dinosaurs, experts say, and continues to challenge decades of accepted theories about the evolution of flight. |
| Anorexics found to have excess fat -- in their bone marrow Researchers have found that girls with anorexia, despite being emaciated, have strikingly high levels of fat in their bone marrow. This can be visualized in MRIs of the knee. The researchers believe that malnutrition causes hormonal alterations that push mesenchymal stem cells in the bone marrow to form fat cells rather than bone-forming cells. This may explain why patients with anorexia have bone loss. |
| Biological risks of eating reptiles Reptiles are bred in captivity primarily for their skins, but some restaurants and population groups also want them for their meat. A study shows that eating these animals can have side effects that call into question the wisdom of eating this 'delicacy.' |
| Butter leads to lower blood fats than olive oil, study finds High blood fat levels normally raise the cholesterol values in the blood, which in turn elevates the risk of atherosclerosis and heart attack. Now a new study shows that butter leads to considerably less elevation of blood fats after a meal compared with olive oil and a new type of canola and flaxseed oil. The difference was stronger in men than in women. |
| Battery-less radios developed Scientists report a 2.4GHz/915MHz wake-up receiver which consumes only 51µW power. This record low power achievement opens the door to battery-less or energy-harvesting based radios for a wide range of applications including long-range RFID and wireless sensor nodes for logistics, smart buildings, healthcare etc. |
| Sporting Prowess Through Brain Power Expert sportsmen are quicker to observe and react to their opponents? moves than novice players, exhibiting enhanced activation of the cortical regions of the brain. More experienced sports players are better able to detect early anticipatory clues from opposing players? body movements, giving them a split second advantage in preparing an appropriate response. |
