<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 ������ý����.</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 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 ������ý���� 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 ������ý���� 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>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 ������ý����’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>Pieter Johnson, assistant professor of ecology and evolutionary biology at CU-������ý����, is having a pretty good year. He and a co-researcher have won an award recognizing outstanding contributions to ecology, and he has been named an Early Career Fellow by the Ecological Society of America.</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>

<p><span>With just over four months until NASA’s next mission to Mars takes flight, the ������ý����, which is leading the effort, continues to work with its partners to knock off critical science and engineering milestones leading up to launch.</span></p>

<p>Solving the “faint young sun paradox” -- explaining how early Earth was warm and habitable for life beginning more than 3 billion years ago even though the sun was 20 percent dimmer than today -- may not be as difficult as believed, says a new ������ý���� study.</p>

<p>A new low-cost method of in-vitro fertilization developed at the ������ý���� that performed successfully in recent human clinical trials in Belgium may help thousands of infertile couples in developing countries.<br /><br /></p>
