Test identifies Red Angus carriers of bone disease Posted: 29 Sep 2011 09:28 AM PDT A new test that detects a rare and deadly bone disorder in Red Angus is now available to cattle producers, thanks to US Department of Agriculture scientists.

New technique gives precise picture of how regulatory RNA controls gene activity Posted: 29 Sep 2011 09:27 AM PDT A new technique allows researchers to identify the exact DNA sequences and locations bound by regulatory RNAs. This information is necessary to understand how the recently identified RNA molecules control the expression of neighboring and distant genes.

Autistic mouse shows striking parallels to human disease Posted: 29 Sep 2011 09:27 AM PDT Mice with a defective version of a single gene show behaviors and symptoms that are remarkably similar to characteristics observed in humans with autism spectrum disorders. The animals also respond similarly to an FDA-approved drug used to treat repetitive behaviors in people with autism.

Lift weights, eat mustard, build muscles? Posted: 29 Sep 2011 07:32 AM PDT If you want to lean out, add muscle and get ripped, new research suggests to look to your garden for help. Scientists have found that when a specific plant steroid was ingested by rats, it triggered a response similar to anabolic steroids with minimal side effects. The stimulatory effect of homobrassinolide on protein synthesis in muscle cells led to increases in lean body mass, muscle mass, and physical performance.
