Quantum quirk: JILA scientists pack atoms together to prevent collisions in atomic clock

February 03, 2011

In a paradox typical of the quantum world, JILA scientists have eliminated collisions between atoms in an atomic clock by packing the atoms closer together. The surprising discovery, described in the Feb. 3 issue of Science Express, can boost the performance of experimental atomic clocks made of thousands or tens of thousands of neutral atoms trapped by intersecting laser beams

Warming North Atlantic water tied to heating Arctic, according to new study

January 27, 2011

The temperatures of North Atlantic Ocean water flowing north into the Arctic Ocean adjacent to Greenland -- the warmest water in at least 2,000 years -- are likely related to the amplification of global warming in the Arctic, says a new international study involving the University of Colorado Boulder.

Improved measurements of sun to advance understanding of climate change

January 14, 2011

WASHINGTON —Scientists have taken a major step toward accurately determining the amount of energy that the sun provides to Earth, and how variations in that energy may contribute to climate change.

Older adults taking popular sleep medicine at risk for falls and cognitive impairment, study finds

January 13, 2011

Adults who take one of the world's most commonly prescribed sleep medications are significantly more at risk for nighttime falls and potential injury, according to a new study by the University of Colorado at Boulder.

Extent of corruption in countries around the world tied to earthquake fatalities

January 12, 2011

A new assessment of global earthquake fatalities over the past three decades indicates that 83 percent of all deaths caused by the collapse of buildings during earthquakes occurred in countries considered to be unusually corrupt.

Men With Macho Faces Attractive to Fertile Women, Researchers Find

January 07, 2011

When their romantic partners are not quintessentially masculine, women in their fertile phase are more likely to fantasize about masculine-looking men than are women paired with George Clooney types.

Desert Dust Reduces Colorado River Flow, Says New Study

September 20, 2010

Dark-colored dust that settles on snow in the Upper Colorado River Basin makes the snow melt early and robs the Colorado River of about 5 percent of its water each year, says a new study co-authored by researchers from the University of Colorado at Boulder-based Cooperative Institute for Research in Environmental Sciences, or CIRES.

CU-NREL Energy Institute Launches Study of Plug-In Hybrid Vehicles in Boulder

September 14, 2010

The University of Colorado at Boulder's Renewable and Sustainable Energy Institute, or RASEI -- a joint venture with the U.S. Department of Energy's National Renewable Energy Laboratory -- will partner with Toyota Motor Sales U.S.A. Inc. in a field study of household experiences and the technical impacts of plug-in hybrid electric vehicles, or PHVs, in a "smart grid" environment.

New International Study Shows Some Asteroids Live in Own 'Little Worlds'

August 25, 2010

While the common perception of asteroids is that they are giant rocks lumbering about in orbit, a new study shows they actually are constantly changing "little worlds" that can give birth to smaller asteroids that split off to start their own lives as they circle around the sun.

New Study Shows How Tortoises, Alligators Thrived in High Arctic Some 50 Million Years Ago

August 24, 2010

A new study of the High Arctic climate roughly 50 million years ago led by the University of Colorado at Boulder helps to explain how ancient alligators and giant tortoises were able to thrive on Ellesmere Island well above the Arctic Circle, even as they endured six months of darkness each year.
