Our Social Nature and Health: Resistance to Viruses
During flu season it’s good to remember that we’re social animals. Our social standing directly impacts our well-being; inequality and health are linked. The relationship between status and health showed up clearly in the Whitehall studies in the U.K. The first study tracked the health of men in the British civil service over a...

Childhood Stress Effects Later Generations: New Epigenetic Evidence
New research published in a Scientific American article shows that descendants of Holocaust survivors have altered stress hormones. This parallels research mentioned in a previous blog post about how the effects of famine ripple through subsequent generations....

I’m not a scientist by training or profession, but I am fascinated by what science can tell us about our social nature. In the past few years, new discoveries and techniques in genetics and data mining have revealed new levels of our interdependence, levels that can impact our genetic inheritance in a single generation...
