Jun 13, 2014 — A new study of athletes suggests exercise may help support a rich, diverse mix of bacteria in the gut. But scientists say the athletes' high-protein diet may also be supporting the community.
Jun 5, 2014 — Scientists used high-powered DNA sequencing to diagnose infections missed by usual lab tests. The pricey method is still experimental, but might offer a way to identify tough-to-diagnose infections.
Apr 23, 2014 — A look at the critters that live on money finds about 3,000 types of bacteria. Most are harmless. But researchers found traces of DNA from anthrax and drug-resistant pathogens, too.
Apr 21, 2014 — Last year a scientist said he'd found a new form of botulinum toxin, and was keeping details secret to keep the recipe from terrorists. But other science and public health labs were shut out, too.
Mar 15, 2014 — Looks like the old adage about when it's safe to eat dropped foods may actually be effective for wet, sticky stuff like candies. For carpet-dusted snacks, you can take your sweet time, a study finds.
Mar 12, 2014 — Research involving more than 1,500 patients suggests people with Crohn's may have too many of the types of gut bacteria that tend to rile the immune system and too few that reduce inflammation.
Nov 18, 2013 — Anxious mice calm down when they get an infusion of gut microbes from mellow mice. That has scientists wondering if gut microbes play a role in the human brain, too. Research on that is only just beginning. But it's intriguing to think there could be a real truth to the phrase "gut feelings."
Nov 6, 2013 — Parents of new babies know they get sick a lot. That may be because infants deliberately suppress their immune systems so that essential microbes have a chance to settle in. An immune suppression system in the blood of newborn babies could be key to building a healthy microbiome.
Nov 4, 2013 — Scientists are asking people to contribute samples of their gut microbes to help figure out how those microbes affect human health. But ethicists say sharing that information, as well as the personal health data that make it useful to researchers, poses risks. That's especially true for children.
Sep 9, 2013 — Trillions of microbes live on and in the human body, tucked into very different ecosystems. Some like the dark, warm confines of the mouth. Others prefer the desert-dry skin of the forearm. The biggest and most active collection of microbes hangs out in the gut.
