A small NASA aircraft completed its first successful science flight Thursday in partnership with the University of Colorado at Boulder as part of an expedition to study the receding Arctic sea ice and improve understanding of its life cycle and the long-term stability of the Arctic ice cover. The mission continues through July 24.

The imaging system on board NASA's Lunar Reconnaissance Orbiter (LRO) recently had its first of many opportunities to photograph the Apollo landing sites. The Lunar Reconnaissance Orbiter Camera (LROC) imaged five of the six Apollo sites with the narrow angle cameras (NACs) between July 11 and 15, within days of the 40th anniversary of the Apollo 11 mission.

Scientists in Louisiana are reporting development of a process for producing large batches of a new and potentially safer form of acetaminophen, the widely used pain-reliever now the source of growing concern over its potentially toxic effects on the liver. Their study, which could speed development of a next-generation pain-reliever, is scheduled for the July 17 issue of ACS' Organic Process Research & Development, a bi-monthly journal.

A group of 34 U.S. Nobel Laureates is calling on President Obama to urge Congress to include the president's proposed $150 billion Clean Energy Technology Fund in the climate legislation it is considering. The climate bill approved by the House in June falls far short of this goal, they told the president in a letter sent to the White House today.

Comprehensive regulation of gun sellers appears to reduce the trafficking of guns to criminals, according to a study led by researchers at the Johns Hopkins Bloomberg School of Public Health. Preventing the diversion of guns to criminals is important because 85 percent of guns recovered by police were recovered from criminal suspects who were not the original purchasers of the guns according to prior research from the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). The Hopkins study is the first to gather and incorporate measures of the enforcement of gun sale laws into a study of the effectiveness of those laws. It is available online in the Journal of Urban Health and in the just-released July 2009 print edition.

Most lacertid lizards are content scurrying in and out of nooks and crannies in walls and between rocks. However, some have opted for an arboreal life style. Neon blue tailed tree lizards (Holaspis guentheri) leap from branch to branch as they scamper through trees in the African forest. There are even anecdotes that the tiny African tree lizards can glide. But without any obvious adaptations to help them to upgrade a leap to a glide, it wasn't clear whether the reptiles really do take to the air and, if they do, how they remain aloft. Intrigued by all aspects of lacertid locomotion, Bieke Vanhooydonck from the University of Antwerp and her colleagues, Anthony Herrel and Peter Aerts, decided to find out whether neon blue tailed tree lizards really glide. Recruiting undergraduate Greet Meulepas to the team, they began filming dainty neon blue tailed tree lizards, gliding geckos (Ptychozoon kuhli) and the common wall lizard (Podarcis muralis) as the animals leapt from a 2m high platform to see if the neon blue tailed tree lizards really could glide. Vanhooydonck and her colleagues publish their discovery that H. guentheri glide like feathers on 17 July 2009 in the Journal of Experimental Biology at http://jeb.biologists.org.

The world's most powerful laser that took $5 billion and a decade recently debuted with a special dedicated at the Livermore National Laboratory in California. The laser is housed inside a football field sized building called the National Ignition Facility. The AP says the laser was designed to help ensure the reliability of the nation's aging nuclear weapons but it could also be used one day to create a more efficient energy source. In 2010, NIF will focus the intense energy of 192 giant laser beams on a BB-sized target filled with hydrogen fuel - fusing, or igniting, the hydrogen atoms' nuclei in the world's first controlled thermonuclear reaction. You can read how the NIF works here.
