Solar energy conversion offers a solution to help mitigate global warming
...t often produces environmental pollutants that are harmful
to human health and greenhouse gases that threaten the global climate. In contrast, solar resources are widely available and have a benign effect on the environment and climate, making it an appealing alternative energy source. "Sunlight is not onl...

effects of a high-fat diet, report researchers at the Salk Institute for Biological Studies. Their findings, detailed in the Proceedings of the National Academy of Sciences, suggest that urocortin 3, a new peptide recently discovered in the insulin s...
Rickettsia felis, a cat-fleaborne pathogen, sheds light on Rickettsial evolution
... Some species of Rickettsia are known to cause harmful
diseases in humans, such as epidemic typhus (R. prowazekii) and Rocky Mountain spotted fever (R. rickettsii), while others have been identified as emerging pathogens and critical agents for the development of bioweapons. The Rickettsia felis bacteriu...
2-step process filters evolution of genes of human and chimpanzee
