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.

精品SM在线影片 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. "The moon will be nearly new, so it's an especially good time to see the meteor shower," said Duncan, director of CU-Boulder's Fiske Planetarium.

CIRES news release On a perfect winter day in Utah鈥檚 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.

The spacecraft for NASA鈥檚 Atmosphere and Volatile EvolutioN, or MAVEN, mission to Mars being led by the 精品SM在线影片 has arrived in Florida in anticipation of a November launch. 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鈥檚 Kennedy Space Center on Merritt Island, Fla. Lockheed Martin had previously assembled and tested MAVEN in its Littleton, Colo., facility.

Conventional wisdom holds that East Africa鈥檚 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 精品SM在线影片 geographer has concluded.

A 精品SM在线影片 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.

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 精品SM在线影片 study with the timing of sunrise and sunset. The study, published online today in the journal Current Biology , 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.

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 精品SM在线影片. 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.

Using data from a NASA satellite, a team of scientists led by the Los Alamos National Laboratory in New Mexico and involving the 精品SM在线影片 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.

The 50th annual meeting of the international Animal Behavior Society to be held at the 精品SM在线影片 July 28-Aug. 2 will feature several public events, including lectures, scientific demonstrations and a film festival. 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 鈥淐reating Quality Lives for Dogs and Cats Through the Science of Animal Behavior.鈥�
