<p>A new high-tech analysis led by a ¶¶Òõ´«Ã½ÔÚÏß researcher shows the oldest known petroglyphs in North America, which are cut into several boulders in western Nevada, date to at least 10,500 years ago and perhaps even as far back as 14,800 years ago.</p>

<p><span>The Mars Atmosphere and Volatile EvolutioN, or MAVEN, mission to Mars will carry just over 1,100 haiku, along with thousands of names, on its journey to the red planet. The haiku were part of a contest, sponsored by the ¶¶Òõ´«Ã½ÔÚÏß, asking the public to submit haiku poetry relating to NASA’s upcoming MAVEN mission to Mars.</span></p>

<p>Researchers at JILA have for the first time used an atomic clock as a quantum simulator, mimicking the behavior of a different, more complex quantum system.</p>

<p>¶¶Òõ´«Ã½ÔÚÏß astrophysicist Doug Duncan says this year's annual Perseid meteor shower and its natural nighttime light show will be particularly good as the display becomes visible over Colorado Aug. 10-13.</p>
<p>"The moon will be nearly new, so it's an especially good time to see the meteor shower," said Duncan, director of CU-¶¶Òõ´«Ã½ÔÚÏß's Fiske Planetarium.</p>

<p>CIRES news release</p>
<p><span>On a perfect winter day in Utah’s Uintah County in 2012, scientists from the Cooperative Institute for Research in Environmental Sciences (CIRES) and colleagues at the National Oceanic and Atmospheric Administration (NOAA) tested out a new way to measure methane emissions from a natural gas production field.</span></p>

<p><span>The spacecraft for NASA’s Atmosphere and Volatile EvolutioN, or MAVEN, mission to Mars being led by the ¶¶Òõ´«Ã½ÔÚÏß has arrived in Florida in anticipation of a November launch.</span></p>
<p>The spacecraft was shipped on Friday, Aug. 2, aboard a U.S. Air Force cargo plane from Buckley Air Force Base in Aurora, Colo., to the Shuttle Landing Facility at NASA’s Kennedy Space Center on Merritt Island, Fla. Lockheed Martin had previously assembled and tested MAVEN in its Littleton, Colo., facility.</p>

<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 ¶¶Òõ´«Ã½ÔÚÏß geographer has concluded.</p>

<p><span>A ¶¶Òõ´«Ã½ÔÚÏß 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 ¶¶Òõ´«Ã½ÔÚÏß 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>
