Team Identifies a Potential Cause of Parkinson’s Disease that May Lead to New Treatment Options

Posted: 20 Nov 2012 05:21 AM PST

Deciphering what causes the brain cell degeneration of Parkinson’s disease has remained a perplexing challenge for scientists. But a team led by scientists from The Scripps Research Institute (TSRI) has pinpointed a key factor controlling damage to brain cells in a mouse model of Parkinson’s disease. The discovery could lead to new targets for Parkinson’s that may be useful in preventing the actual condition.

Eating estrogenic plants alters hormones in monkeys, may increase aggression and sex

Posted: 19 Nov 2012 02:38 PM PST

Eating certain veggies not only supplies key nutrients, it may also influence hormone levels and behaviors such as aggression and sexual activity, says a new study led by researchers at the University of California, Berkeley, that could shed light on the role of diet in human evolution.

The research is the first to observe the connection between plant-based estrogenic compounds, or phytoestrogens, and behavior in wild primates — in this case, a group of red colobus monkeys in Uganda.

Making ‘nanospinning’ practical

Posted: 19 Nov 2012 02:24 PM PST

Nanofibers — strands of material only a couple hundred nanometers in diameter — have a huge range of possible applications: scaffolds for bioengineered organs, ultrafine air and water filters, and lightweight Kevlar body armor, to name just a few. But so far, the expense of producing them has consigned them to a few high-end, niche applications.
