Nov 25, 2013 — Making your own cheese and yogurt is all the rage these days. Now a scientist has taken the DIY craze to an entirely new level. She and an artist have made cheeses using the microcritters on their own skin, as well as those from famous folks. The curds are on display at a museum.
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 8, 2013 — It may be possible to cultivate a healthier community of bacteria on and inside us by modifying our diet. For starters, eating more vegetables probably won't hurt.
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 18, 2013 — Science may seem advanced, may even be advanced, but that doesn't mean there aren't still plenty of questions left to ask and answer. A new book catalogs 20 of the biggest questions outstanding. Physicist Marcelo Gleiser looks the list over and ponders some of the subjects keeping scientists awake at night.
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.
Sep 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.
Aug 28, 2013 — Lean people tend to have many more kinds of intestinal bacteria than obese people. Having too few species, regardless of your weight, appears to increase the risk for Type 2 diabetes, heart disease and cancer.
Aug 8, 2013 — The bacteria that cause many cases of ear infection in kids and pneumonia in the elderly are usually harmless until activated by distress signals from their human host. When the flu or another virus gives you a fever, for example, mild-mannered pneumococcus can turn nasty.
