Dr Bikul Das is an Indian scientist at Stanford University School of Medicine. He has found that altruism is far more common in Homo sapiens, and goes right down to our cells. In a study he has revealed that human embryonic stem cells  under duress produce molecules that not only benefit themselves but also help nearby cells survive. The path-breaking find, say doctors, might mean that in the near future such cells can be injected into cancerous tissue to generate killer cells, which will then wipe out malignant tumours.
