When the Dark Energy Camera opened its giant eye last week and began taking pictures of the ancient light from far-off galaxies, more than 120 members of the Dark Energy Survey eagerly awaited the first snapshots. Those images have now arrived.
If recent research in Norway is successful, a coating filled with tiny lubricant capsules could come to the rescue when metal surfaces dry out and friction builds up. As part of a project at the Gemini Tribology Centre researchers are now testing whether it is possible—where two metal surfaces are in contact with each other—to apply a coating to surfaces formed of hard particles and capsules filled with liquid lubricant.
This morning the Large Hadron Collider (LHC) collided protons with lead ions for the first time. This week's short run will give the experiments a first taste of proton-nucleus collisions before the main run in January to February 2013, the last LHC physics before the accelerator is shut down for maintenance.
According to data from a 2008 Business R&D and Innovation Survey by the National Science Foundation, businesses perform the lion's share of their R&D activity in just a small number of geographic areas, particularly the San Jose-San Francisco-Oakland area and the New York-Newark-Bridgeport area.
A frustrating flaw in a set of custom crystals for an instrument at SLAC National Accelerator Laboratory inspired a solution for an important scientific challenge: how to accurately measure the colors of each individual pulse from a powerful X-ray laser.
Scientific deep sea drilling vessel “Chikyu” has set a world new record by drilling down and obtaining rock samples from deeper than 2,111 m (6,926 feet) below the seafloor off Shimokita Peninsula of Japan in the northwest Pacific Ocean. “Chikyu” is designed to reach the deeper part of the Earth such as the mantle, the plate boundary seisomogenic zones and the deep biosphere.
A new underwater explorer hit the seas this summer, armed with cameras, strobes and sonar and charged with being a protector of sorts to a half-billion dollar resource—the Atlantic scallop catch. Developed by a former scalloper and researchers at the Woods Hole Oceanographic Institution, the stainless steel Seahorse gives marine scientists a look at the seafloor they’ve never had before and offers uses beyond policing scallop grounds.
Many lasers have linear polarization, in which the electric field of the beam is, for example, vertical everywhere. Radial and azimuthal polarizations, however, have a directional change of electric field. By combining a spatial light modulater, a 100 femtosec pulse laser source, and a wave plate, researchers in the U.K. have produced lasers that use these modes to machine materials with portentially greater process efficiency.
By modifying the rate at which chemical reactions take place, nanoparticle catalysts fulfill myriad roles in industry, the biomedical arena, and everyday life. Finding new and more effective nanoparticle catalysts to perform applications in these areas has become vital. Now, a researcher at Arizona State University has found a clever way to measure catalytical reactions of single nanoparticles and multiple particles printed in arrays, which will help to characterize and improve existing nanoparticle catalysts.
Members of the Mars Science Laboratory Curiosity rover ChemCam team have received the first photos from the instrument's remote microimager. The successful capture of ChemCam's first 10 photos sets the stage for the first test bursts of the instrument's rock-zapping laser in the near future.
More than three centuries ago, a French explorer's ship sank in the Gulf of Mexico, taking with it France's hopes of colonizing a vast piece of the New World—modern-day Texas. Like La Salle in 1685, researchers at Texas A&M University are in uncharted waters as they try to reconstruct his vessel with a gigantic freeze-dryer, the first undertaking of its size.
The new SMART position sensor provides a high level of accuracy needed for transportation and industrial applications, measuring values down to 0.01 degree.
