Study of 90 animals' thigh bones reveals how they can efficiently carry loads (March 14, 2011) -- The structures inside animals' thigh bones that enable them to support huge loads whilst being relatively lightweight are revealed in a new study. The researchers say their work could lead to the development of new materials based on thigh bone geometry. ... > full story

Breakthrough in nanocomposite for high-capacity hydrogen storage (March 14, 2011) -- Researchers have designed a new composite material for hydrogen storage consisting of nanoparticles of magnesium metal sprinkled through a polymer related to Plexiglas that rapidly absorbs and releases hydrogen at modest temperatures without oxidizing the metal after cycling. This achievement is a major breakthrough in materials design for hydrogen storage, batteries and fuel cells. ... > full story

Lunar Reconnaissance Orbiter: The far side of the moon -- and all the way around (March 14, 2011) -- Because the moon is tidally locked (meaning the same side always faces Earth), it was not until 1959 that the farside was first imaged by the Soviet Luna 3 spacecraft. And what a surprise --­ unlike the widespread maria on the nearside, basaltic volcanism was restricted to a relatively few, smaller regions on the farside, and the battered highlands crust dominated. The cause of the farside/nearside asymmetry is an interesting scientific question. Past studies have shown that the crust on the farside is thicker, likely making it more difficult for magmas to erupt on the surface, limiting the amount of farside mare basalts. Why is the farside crust thicker? ... > full story

Physicists measure current-induced torque in nonvolatile magnetic memory devices (March 14, 2011) -- Tomorrow's nonvolatile memory devices -- computer memory that can retain stored information even when not powered -- will profoundly change electronics, and researchers have discovered a new way of measuring and optimizing their performance. ... > full story

Researchers use lasers, custom microscope to show gene splicing process in real time (March 14, 2011) -- Researchers have developed a way to use lasers to study the splicing of pre-messenger RNA molecules, an essential process in creating proteins to sustain advanced organisms, including human life. Now this process of splicing, carried out by a cellular micro-machine called the spliceosome, can be viewed in real time. The research paper culminates a five-year-long collaboration of three research laboratories. ... > full story

Ultra high speed film (March 14, 2011) -- How fast an intense laser pulse can change the electrical properties of solids is revealed by new research. Scientists are following the course of electronic switching processes which occur within fractions of a second (femtoseconds). The results of their research may trigger future developments of custom-made and ultra fast opto-electronic components in order to increase data transmission rates or to accelerate optical switches, to name just one example of potential areas of application. ... > full story

Nanotech-enabled consumer products continue to rise (March 13, 2011) -- Over 1,300 manufacturer-identified, nanotechnology-enabled products have entered the commercial marketplace around the world. The most recent update to the group's five-year-old inventory reflects the continuing use of the tiny particles in everything from conventional products like non-stick cookware to more unique items such as self-cleaning window treatments. ... > full story

Color view from orbit shows Mars rover beside crater (March 13, 2011) -- NASA's Mars Exploration Rover Opportunity has nearly completed its three-month examination of a crater informally named "Santa Maria," but before the rover resumes its overland trek, an orbiting camera has provided a color image of Opportunity beside Santa Maria. ... > full story

Dawn mission gets Vesta asteroid target practice (March 13, 2011) -- In the lead-up to orbiting the second most massive body in the asteroid belt this coming July, planners of NASA's Dawn mission to the giant asteroid Vesta and scientists have been practicing mapping Vesta's surface, producing still images and a rotating animation that includes the scientists' best guess to date of what the surface might look like. ... > full story
