Embryo survival gene may fight range of diseases: study  Monday, Nov 26, 2012 02:05 AM PST HONG KONG (Reuters) - A gene that keeps embryos alive appears to control the immune system and determine how it fights chronic diseases like hepatitis and HIV, and autoimmune diseases like rheumatoid arthritis, scientists said on Monday. Although the experts have only conducted studies on the gene Arih2 using mice, they hope it can be used as a target for drugs eventually to fight a spectrum of incurable diseases. Lead author Marc Pellegrini at the Walter and Eliza Hall Institute of Medical Research in Australia said the gene appears to act like a switch, flipping the immune system on and off. ...

Sea snails show impact of more acidic ocean  Sunday, Nov 25, 2012 08:31 PM PST LONDON (Reuters) - The shells of some marine snails in the seas around Antarctica are dissolving as the water becomes more acidic, threatening the food chain, a study published in the journal Nature Geoscience said on Sunday. Oceans soak up about a quarter of the carbon dioxide released into the atmosphere each year and as CO2 levels in the atmosphere increase from burning fossil fuels, so do ocean levels, making seas more acidic. Ocean acidification is one of the effects of climate change and threatens coral reefs, marine ecosystems and wildlife. ... Full Story	Top
