Scientists revealed the most extensive findings to date on the genetics of autism on Sunday, pinpointing two new genetic links that may predispose children to develop the complex brain disorder. The five-year study, led by an international consortium of researchers from 19 nations, indicated autism had numerous genetic origins rather than a single or a few primary causes. The researchers scoured DNA samples from 1,168 families with two or more children with autism, and used "gene chip" technology to detect genetic similarities. They also looked for tiny insertions and deletions of genetic material that could play a role in autism. ادامه مطلب

Researchers are trying to find ways to regrow fingers and someday, even limbs with tricks that sound like magic spells from a Harry Potter novel. There is the guy who sliced off a fingertip but grew it back, after he treated the wound with an extract of pig bladder. And the scientists who grow extra arms on salamanders. And the laboratory mice with the eerie ability to heal themselves. This summer, scientists are planning to see whether the powdered pig extract can help injured soldiers regrow parts of their fingers. And a large federally funded project is trying to unlock the secrets of how some ani-mals regrow body parts so well, with hopes of applying the lessons to humans. ادامه مطلب

Those opposed to pharming fear that through either mishandling or gene flow, potentially dangerous pharmacauticals may inadvertently enter the food supply. Precedents involving non-pharmaceutical genetically modified crops include the Starlink controversy, and trade war over genetically modified food between the European union and the USA. A similar reaction to pharmed rice is feared from Japan. ادامه مطلب
