Streptococcus bacteria, like this strain, can be found in our guts.

July 4, 2013 An experimental "gut check" test can tell us more about the bacteria that live inside us. By studying the way the microbial populations change over time, researchers think they may have a new tool for monitoring health.

Fungi (cyan) surround a human hair within the skin. A study in the journal Nature shows the population of fungi on human skin is more diverse that previously thought.

May 22, 2013 While studying microorganisms on humans is not new, tracking fungi is. In a census of sorts, scientists checked the skin of healthy volunteers. They found an expansive ecosystem of silent inhabitants.

Mango Doucleff is always ready with a germ-laden slurp for her owner's face and ears.
April 18, 2013 Dog owners have similar germs growing on their skin: a signature blend of bacteria from canines' tongues and paws. Scientists couldn't find an analogous signature for cat owners. Perhaps cats are just being selfish.
Oh, Portland: the Hopworks Urban Brewery's "pub bike."

April 5, 2013 Saccharomyces cerevisiae is poised to become the nation's first official state microbe. Oregon is grateful, very grateful, for all the yeast has done for the state's booming craft beer industry.
Yeast affects several aspects of beer including the foam, or head, that forms on the of the glass. If fermentation is too vigorous, too many of the foam-stabilizing proteins may be lost.

February 8, 2013 Yeast are demanding little critters. To make good-tasting beer, brewers have to pamper them like pedigreed pets. A new report says it's all about the microbiology. Brewers say they use science to keep their charges happy.
Twins in Malawi helped scientists discover a role the gut microbiome appears to play in severe malnutrition.

January 30, 2013 The bacteria that live in humans' guts influence weight gain and health. By studying twins in Malawi, scientists have found that changes in this microbial community may also turn malnutrition into a fatal condition.

May 9, 2012 While U.S. adults have relatively uniform microbe colonies in their guts, adults in Malawi and Amazonia have much more diverse populations. Scientists are still struggling with why that is and what it means.
