A new look at the diets of ancient African hominids shows a “game changer” occurred about 3.5 million years ago when some members added grasses or sedges to their menus, according to a new study led by the University of Colorado Boulder.
A person searching through the massive expanse of data collected by the U.S. Census Bureau in search of details about a specific neighborhood may increasingly find statistics with colossal margins of error, such as an average income of $50,000 plus or minus $50,000.
At first, Kisori Thomas had a difficult time acclimating to the campus climate at CU-Boulder. Initially, other than her coursework, she wasn’t active outside the classroom.
Realizing she wanted a more well-rounded education, experience and personal growth, she took a big step outside her comfort zone and began looking for student leadership and multicultural organizations to join. This also included studying abroad in Chicoutimi, Canada, for a five-week French intensive program.
Self-manufactured crises -- like the looming "fiscal cliff" -- may help Congress get work done, according to a new book co-authored by Professor Scott Adler.

“I pretty much had no construction experience,” Smith said. “I didn’t own any tools, so there was a pretty big learning curve.”
A team of researchers led by the University of Colorado Boulder recently discovered the first prehistoric bronze artifact made from a cast ever found in Alaska, a small, buckle-like object found in an ancient Eskimo dwelling and which likely originated in East Asia.

For the past six decades, archaeologists have documented dense populations of ancient Maya in Mexico and Central America—hundreds of people per square kilometer.
