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.
Israeli war planes bombed the center of Gaza City again on Monday, as the Palestinian death toll neared the 100 mark.
