Predicting menopause: Is reproductive lifespan genetic?

Women may soon know their personal reproductive timeframe, as researchers have identified nearly 300 genes associated with the beginning of menopause.

How the clownfish earned its stripes

How quickly clownfish get their white stripes depends on which anemones they live with, according to a new study published in PNAS.

Bad hormones

Prolonged use of hormones may have long-term consequences for women. A team of researchers led by Alain Weill from French National Health Insurance, found that the long-term use of the hormone drug cyproterone acetate (CPA) is linked to a 7-fold increase in risk of developing brain tumours in women.  CPA is a synthetic progesterone that … Continue reading Bad hormones

The problem is, female brains can have starkly different neuroimmune responses from males. And our lack of basic understanding is having a very real … Continue reading Scientists don’t really get the female brain
