The health of Colorado’s bighorn sheep population remains as precarious as the steep alpine terrain the animals inhabit, but a new study led by researchers at the University of Colorado Boulder has found that inbreeding—a common hypothesis for a recent decline—likely isn’t to blame.

You don’t think you’re hungry, then a friend mentions how hungry he is or you smell some freshly baked pizza and whoaaa, you suddenly feel really hungry. Or, you’ve had surgery and need a bit of morphine for pain. As soon as you hit that button you feel relief even though the medicine hasn’t even hit your bloodstream.

A team of researchers has developed a wireless device the width of a human hair that can be implanted in the brain and activated by remote control to deliver drugs.

The New Horizons spacecraft made a successful flyby of Pluto this morning after a nine-year, 3 billion-mile-journey, sending a thumbs-up signal to Earth tonight and elating the world’s space science community, including CU Boulder participants.

When the New Horizons spacecraft encountered Pluto early this morning, several CU-Boulder alumni realized a decade full of dreams and no one more so than Beth Cervelli.

After a nine-year journey of 3 billion miles, a piano-sized, power-packed NASA spacecraft has an upcoming date with history that some University of Colorado Boulder students, faculty and alumni wouldn’t miss for the world.

Southern Californians and writers love to blame the hot, dry Santa Ana winds for tense, ugly moods, and the winds have long been associated with destructive wildfires. Now, NOAA researchers have fo und that on occasion, the winds have an accomplice with respect to fires, at least: Natural atmospheric events known as stratospheric intrusions, which bring extremely dry air from the upper atmosphere down to the surface, adding to the fire danger effects of the Santa Anas, and exacerbating some air pollution episodes.

This summer, middle and high school students are helping build and test 3-D structures that complement and mimic the cutting-edge ‘photo origami’ research conducted at the University of Colorado Boulder.

It’s been difficult to explain patterns of toxic mercury in some parts of the world, such as why there’s so much of the toxin deposited into ecosystems from the air in the southeastern United States, even upwind of usual sources. A new analysis led by researchers at the University of Colorado Boulder shows that one key to understanding mercury’s strange behavior may be the unexpected reactivity of naturally occurring halogen compounds from the ocean.

A University of Colorado Boulder scientist unexpectedly discovered two lichen species new to science in the same week while conducting research in Boulder Colorado, near the city’s eastern limits.
