<p>Conventional wisdom holds that East Africa’s Maasai pastoralists hunt lions for two distinct reasons: to retaliate against lions that kill livestock or to engage in a cultural rite of passage. But that view reflects mistranslations of Maasai terms and a simplification of their cultural traditions and their relationship with wildlife, a team of researchers led by a University of Colorado Boulder geographer has concluded.</p>

<p><span>A University of Colorado Boulder team has developed a radically new technique that uses the power of sunlight to efficiently split water into its components of hydrogen and oxygen, paving the way for the broad use of hydrogen as a clean, green fuel.</span></p>

<p>Spending just one week exposed only to natural light while camping in the Rocky Mountains was enough to synch the circadian clocks of eight people participating in a University of Colorado Boulder study with the timing of sunrise and sunset.</p>
<p>The study, published online today in the journal <em>Current Biology</em>, found that the synchronization happened in that short period of time for all participants, regardless of whether they were early birds or night owls during their normal lives. </p>

<p>Year-round ice-free conditions across the surface of the Arctic Ocean could explain why the Earth was substantially warmer during the Pliocene Epoch than it is today, despite similar concentrations of carbon dioxide in the atmosphere, according to new research carried out at the University of Colorado Boulder.</p>
<p>In early May, instruments at the Mauna Loa Observatory in Hawaii marked a new record: The concentration of carbon dioxide climbed to 400 parts per million for the first time in modern history. </p>

<p>The spring semester grade numbers are in for the University of Colorado athletic program, and the most recent news parallels that of the last four years as the 300 student-athletes enrolled in the 2013 spring semester had a collective term grade point average of 2.892.</p></div>

<p class="p1">Using data from a NASA satellite, a team of scientists led by the Los Alamos National Laboratory in New Mexico and involving the University of Colorado Boulder have discovered a massive particle accelerator in the heart of one of the harshest regions of near-Earth space, a region of super-energetic, charged particles surrounding the globe known as the Van Allen radiation belts.</p>

<p><span>The 50th annual meeting of the international Animal Behavior Society to be held at the University of Colorado Boulder July 28-Aug. 2 will feature several public events, including lectures, scientific demonstrations and a film festival.</span></p>
<p>The public lectures, to be held at the Glenn Miller Ballroom in the University Memorial Center, are part of the Applied Animal Behavior Public Day on Sunday, July 28, titled “Creating Quality Lives for Dogs and Cats Through the Science of Animal Behavior.”  </p>

<p>The University of Colorado Boulder today announced that Ryan Chreist has been named assistant vice chancellor for alumni relations. Chreist, who most recently served as the director of recruitment, operations and system integration for the CU-Boulder Office of Admissions, starts this week.</p>

<p>Lucy Sanders, CEO for the National Center for Women & Information Technology (<a href="http://www.ncwit.org/">NCWIT</a>) was recently recognized as a national U.S. News STEM Leadership Hall of Fame awardee. NCWIT is a non-profit organization housed within the University of Colorado Boulder’s <a href="http://www.colorado.edu/engineering/">College of Engineering and Applied Science</a>, and helps its members more effectively recruit, retain and advance girls and women in K-12 through college education, and from academic to corporate and startup careers.</p>

<p>As a class, people who don’t drink at all have a higher mortality risk than light drinkers. But nondrinkers are a diverse bunch, and the reasons people have for abstaining affects their individual mortality risk, in some cases lowering it on par with the risk for light drinkers, according to a University of Colorado study.</p>
