<p>A research team led by the ���Ĵ�ý has discovered a mechanism in the brain that is key to making cocaine seem pleasurable, a finding that could lead to a drug treatment for fighting addiction.</p>
<p>The findings build on past research also involving CU-���Ĵ�ý that found the same mechanism in the brain also interacts with heroin, oxycodone, morphine and other opioid drugs to amplify their addictiveness. The latest study suggests that the mechanism plays a key role in the addictiveness of many abused drugs, possibly including methamphetamine and alcohol.</p>

<p>Up for a romantic Valentine’s Day evening? Then head to the ���Ĵ�ý’s Fiske Planetarium to <em>Relativity for Lovers – A Valentine’s Day Among the Stars</em>, for music, film and a talk on the genius of Albert Einstein.</p>

<p>NASA’s fallen astronauts, including ���Ĵ�ý alumni Ellison Onizuka and Kalpana Chawla, who died in space shuttle accidents 17 years apart, will be remembered both on campus and in a special NASA online tribute this week.</p>

<p class="p1">Arctic sea ice extent plunged precipitously from 2001 to 2007, then barely budged between 2007 and 2013. Even in a warming world, researchers should expect such unusual periods of no change—and rapid change—at the world’s northern reaches, according to a new paper.</p>

<p>When evacuees become separated from their pets while fleeing hurricanes, wildfires or other natural disasters, they’re often difficult to reunite.</p>
<p>Computer scientists at the ���Ĵ�ý hope to change that with a new online tool designed to leverage the work of crowds to reconnect pets with their human families.</p>

<p>���Ĵ�ý researchers will update NASA officials next week on a revolutionary space telescope concept selected by the agency for study last June that could provide images up to 1,000 times sharper than the Hubble Space Telescope.</p>

<p>���Ĵ�ý Distinguished Professor W. Carl Lineberger was honored today by the National Academy of Sciences (NAS) for his extraordinary scientific achievements.</p>

<p>To accurately forecast wintertime bad air days in Utah’s Uintah Basin, researchers must use real atmospheric measurements to estimate chemical emissions from nearby oil and natural gas fields, a new study in <em>Atmospheric Chemistry and Physics </em>has found.</p>

<p>Using simulation to walk in the shoes of a person who is blind -- such as wearing a blindfold while performing everyday tasks -- has negative effects on people’s perceptions of the visually impaired, according to a ���Ĵ�ý study.</p>

<p>A new study led by the ���Ĵ�ý finds that when we use our thoughts to dull or enhance our experience of pain, the physical pain signal in the brain—sent by nerves in the area of a wound, for example, and encoded in multiple regions in the cerebrum—does not actually change. Instead the act of using thoughts to modulate pain, a technique called “cognitive self-regulation” that is commonly used to manage chronic pain, works via a separate pathway in the brain.</p>
