A group of Denver high school students who recently descended on the CU-ºù«ÍÞÊÓƵ campus rolled up their sleeves for a week of real-world engineering experience and the opportunity to earn $2,500 scholarships.

Some of the beasts living in Patagonia 13,000 years ago were an intimidating bunch: Fierce saber-toothed cats, elephant-sized sloths, ancient jaguars as big as today’s tigers and short-faced bears that stood 12 feet tall and weighed nearly a ton. But by 12,000 years ago, they had disappeared. What happened?

Global emissions of ethane, an air pollutant and greenhouse gas, are on the uptick again. A team led by CU-ºù«ÍÞÊÓƵ found that a steady decline of global ethane emissions following a peak in about 1970 ended between 2005 and 2010 in most of the Northern Hemisphere and has since reversed. Between 2009 and 2014, ethane emissions in the Northern Hemisphere increased by about 400,000 tons annually, the bulk of it from North American oil and gas activity.

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.

For some comets, breaking up is not that hard to do. A new study led by Purdue University and CU-ºù«ÍÞÊÓƵ 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.

A CU-ºù«ÍÞÊÓƵ research team thinks the same type of liquid crystals you see in the display panel of your smart phone may be the key component in a new window coating that could lower energy costs in buildings across the nation.

Social scientists and health researchers from across Colorado and neighboring states will soon have abundant U.S. Census and other federal statistical data available to them in a secure setting at the ºù«ÍÞÊÓƵ. The National Science Foundation this month awarded $300,000 over three years to CU-ºù«ÍÞÊÓƵ to create the Rocky Mountain Research Data Center (RMRDC), which will be housed in the Institute of Behavioral Science (IBS).

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.

Injections of the soil bacterium "Mycobacterium vaccae" ("M. vaccae" NCTC 11659) promote stress resilience and improve coping behaviors in mice, according to a new study led by the ºù«ÍÞÊÓƵ.

The bread loaf-sized Miniature X-Ray Solar Spectrometer, or MinXSS, CubeSat will be deployed from an airlock on the International Space Station (ISS) at 4 a.m. MDT on Monday, May 16, beginning its journey into space where it will study emissions from the sun that can affect ground-based communications systems.
