A light micrograph image of telomeres, shown in yellow, at the end of human chromosomes. Women tend to have longer telomeres than men and tend to outlive men, according to new research matching genetic information with medical records.
A massive research project in California is beginning to show how genes, health habits and the environment can interact to cause diseases. And it's all possible because 100,000 people agreed to contribute some saliva in the name of science.
The Obama Administration is hoping allies like Egypt and Turkey use their influence to persuade Hamas to stop firing rockets into Israel.

Kircher was something of a jack-of-all-trades. He wrote more than 30 books; he was a philosopher, an inventor, a historian, a scientist. Back in his day, everyone knew about him. But it didn't help his reputation that many of his theories and inventions just couldn't hold water.
