CU-Boulder-led Team Gets First Look at Diverse Life Below Rare Tallgrass Prairies

Published: October 31, 2013.
Released by University of Colorado at Boulder  


America's once-abundant tallgrass prairies—which have all but disappeared—were 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.

Empathy for Others' Pain Rooted in Cognition Rather Than Sensation, CU-Boulder Study Finds
The ability to understand and empathize with others' pain is grounded in cognitive neural processes rather than sensory ones, according to the results of a new study led by University of Colorado Boulder researchers. The findings show that the act of perceiving others' pain (i.e., empathy for others' pain) does not appear to involve the same neural circuitry as experiencing pain in one's own body, suggesting that they are different interactions within the brain.

Mounting Tension in the Himalaya
The Gorkha earthquake struck Nepal on April 25, 2015. It's a part of the world that is prone to earthquakes, as the Indian plate makes its incremental, sticky descent beneath the Eurasian plate. The magnitude 7.8 jolt, which was very shallow (only 15 km underground), caused a tremendous amount of damage in Kathmandu. But it didn't rupture the Earth's surface, signifying that only part of the fault had slipped, below-ground.

Milky Way Now Hidden from One-third of Humanity
The Milky Way, the brilliant river of stars that has dominated the night sky and human imaginations since time immemorial, is but a faded memory to one third of humanity and 80 percent of Americans, according to a new global atlas of light pollution produced by Italian and American scientists.

'Wasteful' Galaxies Launch Heavy Elements into Surrounding Halos And Deep Space
Galaxies "waste" large amounts of heavy elements generated by star formation by ejecting them up to a million light years away into their surrounding halos and deep space, according to a new study led by the University of Colorado Boulder.

Purdue, CU-Boulder Study Shows How Comets Break Up, Make Up
For some comets, breaking up is not that hard to do. A new study led by Purdue University and the University of Colorado Boulder indicates the bodies of some periodic comets - objects that orbit the sun in less than 200 years - may regularly split in two, then reunite down the road. In fact, this may be a repeating process fundamental to comet evolution, according to the study, which is being published in Nature on June 1.

Narcotic Painkillers Prolong Pain in Rats, Says CU-Boulder Study
The dark side of painkillers - their dramatic increase in use and ability to trigger abuse, addiction and thousands of fatal overdoses annually in the United States is in the news virtually every day. Brace for another shot across the bow: Opioids like morphine have now been shown to paradoxically cause an increase in chronic pain in lab rats, findings that could have far-reaching implications for humans, says a new study led by the University of Colorado Boulder.

Global Data Shows Inverse Relationship, Shift in Human Use of Fire
Humans use fire for heating, cooking, managing lands and, more recently, fueling industrial processes. Now, research from the University of Colorado has found that these various means of using fire are inversely related to one another, providing new insight into how people are changing the face of fire.
