Delivering healthy bacteria in a pill could help patients harboring out-of-balance microbial communities. Yogurt eaters already know that not all bacteria are bad for you. They may not realize that some bacteria are so important that one day people may fight off disease with pills filled with ba... Read More
Scientists are reporting an advance in smartphone-based imaging that could help physicians in far-flung and resource-limited locations monitor how well treatments for infections are working by detecting, for the first time, individual viruses. Their study on the light-weight device, which conver... Read More

Rewind Earth's story 3 or 4 billion years, to when life was emerging. The surface of our planet was starting to cool but still piping hot – possibly about 200 °C. Early, unstable continents may have been forming. Now imagine life doesn't emerge, and press play.
This is what a new computer mod... Read More
Scanning electron micrograph of a murine macrophage infected with Francisella tularensis strain LVS. Macrophages were dry-fractured by touching the cell surface with cellophane tape after critical point drying to reveal intracellular bacteria. Bacteria (colorized in blue) are located either in t...
