The initial results are now coming in for a project led by CU-Boulder that is expected to eventually sequence the gut bacteria of tens of thousands of people around the world in hopes of better understanding nutrition and health. The crowd-funded effort, known as the American Gut project, or AG, has thus far sequenced microbes from the digestive tracts of 1,589 people and has received $615,000 in donations from more than 6,700 people and four companies. Led by CU-Boulder Professor Rob Knight of the BioFrontiers Institute, the effort is the largest crowd-funded science project ever undertaken.

One of the first steps people take toward rebuilding their communities after a flood, wildfire or other disaster may not be the right step, according to the director of the Natural Hazards Center at the University of Colorado Boulder. 鈥淲hen a disaster happens, people feel pressure to rebuild things just as they were before, when in fact a disaster should be a time when there is a pause, when we ask 鈥楬ow can we build it back better than it was before?鈥� 鈥� said center Director Kathleen Tierney, also a professor of sociology.

In an example of the challenges water-strapped Western cities will face in a warming world, new research shows that every degree Fahrenheit of warming in the Salt Lake City region could mean a 1.8 to 6.5 percent drop in the annual flow of streams that provide water to the city.

America鈥檚 once-abundant tallgrass prairies鈥攚hich have all but disappeared鈥攚ere home to dozens of species of grasses that could grow to the height of a man, hundreds of species of flowers, and herds of roaming bison. For the first time, a research team led by the University of Colorado Boulder has gotten a peek at another vitally important but rarely considered community that also once called the tallgrass prairie home: the diverse assortment of microbes that thrived in the dark, rich soils beneath the grass.
