It's interesting that hormone levels may affect success in the financial markets. The hormones testosterone and cortisol may reflect different stress triggers. The study finds a correlation between high and low testosterone levels and a higher or lower rate of success in stock trades, perhaps because of an increase or decrease in risk-taking. Female traders seem to be immune to this particular set of mood swings.

Bcl-2 is the target of a UV-inducible apoptosis switch and a node for UV signaling

addict submitted, created time 1 year 6 months (www.pnas.org)

Sunlight's UVB radiation triggers cell signaling at multiple sites to induce apoptosis. The integration of these signal entry sites is not understood. Here we show that P53 and E2f1 constitute a UV-inducible apoptosis switch. At low-UV doses, wild-type cells resemble the OFF state of an siP53-treated cell, whereas at high-UV doses, the apoptosis frequency transitions to the fully ON behavior of an siE2f1-treated cell
