'Personality-gene' makes songbirds curious

... ..... Whether you are an anxious type, or a fearless person - such individual differences in personality could be partly due to the genes you carry. In humans, it is hard to prove the existence of such "personality genes" - there are simply too many factors that influence human behaviour and these factors are hard to control experimentally. Birds are an easier target for research and indeed,...

Could estriol be the elixir for MS?

... Some years back, Dr. Rhonda Voskuhl, director of UCLA's Multiple Sclerosis Program, and her colleagues discovered the cause. They found that a female sex hormone called estriol, which is produced during pregnancy, was responsible for the suppression. Four years ago, Voskuhl followed that discovery with a pilot study in which 10 non-pregnant women with MS were given estriol, yielding what sh...
