November 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."
November 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.
November 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.
November 4, 2013 Bacteria aren't all bad for you. In fact, they may well be the reason you're healthy. Scientists are just starting to figure out the role that the microorganisms that live on the human body play in human health. We dive in to take a microbe's eye view of the hidden world of the human microbiome.
October 24, 2013 The painkiller OxyContin is already classified as a Schedule II drug because of the "severe" risk of addiction. Now the Food and Drug Administration wants to move Vicodin and other painkillers containing hydrocodone to Schedule II as well, citing soaring rates of addiction and overdose deaths.
September 12, 2013 Eight outbreaks of measles have infected at least 159 people so far this year, the CDC reports. All of the outbreaks were caused by people traveling internationally and bringing the virus back to the U.S. Communities that don't vaccinate children for religious reasons were hardest hit.
September 10, 2013 In the latest attempt to stem an epidemic of opioid painkiller overdoses, the FDA tightened prescribing guidelines. The drugs should only be used for patients with severe pain when other treatments have failed, the agency says, not for moderate pain.
September 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.
September 5, 2013 Mice that got microbe transplants from obese humans gained more weight and accumulated more fat than mice that received microbes from lean humans. The findings, though preliminary, suggest a future path for obesity treatment.
