    Germs help each other fend off antibiotics

    Drug-resistant bacteria can cause persistent infections. A new study finds these germs fight drugs in different ways. And they can swap various compounds, increasing their neighbors’ chances of overcoming the drugs meant to kill them.

  3. Food can make an appetizing science fair project

    Many students think they need a laboratory or special equipment for a winning research project. But finalists at the Broadcom MASTERS competition showed food-based research may require little more than your home kitchen
