To improve fuel cell module durability and predict longevity, researchers are studying the degradation mechanisms of the fuel cells that occur under real-world transit bus conditions. While quantifying the effects of electrode degradation stressors in the operating cycle of the bus on the membrane lifetime, the team has discovered links between electrode degradation and membrane durability.

Using clouds of ultracold atoms and a pair of lasers operating at optical wavelengths, researchers have reached a quantum network milestone: entangling light with an optical atomic coherence composed of interacting atoms in two different states. The development could help pave the way for functional, multimode quantum networks.
South Korea's sole nuclear power plant operator said Thursday that investigators raided its offices, a sign that a probe into faulty nuclear plant cables is widening. Korea Hydro & Nuclear Power Co. spokesman Lee Yoon-doing said prosecutors seized documents and computer hard drives from at least four of the company's offices, including its headquarters in southeastern Gyeongju.
Stratasys, a leading maker of 3-D printers, is buying another 3-D printer manufacturer, MakerBot, for $403 million in stock. Stratasys Ltd. says the acquisition will enable it to offer affordable desktop 3-D printers. MakerBot's owners will receive 4.76 million newly issued Stratasys shares and are eligible for another 2.38 million through the end of 2014 if certain performance targets are met.
Improved methods for breaking down cellulose nanofibers are central to cost-effective biofuel production and the subject of new research from Los Alamos National Laboratory and the Great Lakes Bioenergy Research Center. Scientists are investigating the unique properties of crystalline cellulose nanofibers to develop novel chemical pretreatments and designer enzymes for biofuel production from cellulosic—or non-food—plant derived biomass.
A new Lawrence Berkeley National Laboratory study challenges the orthodoxy of microbiology, which holds that in response to environmental changes, bacterial genes will boost production of needed proteins and decrease production of those that aren’t. The study found that for bacteria in the laboratory there was little evidence of adaptive genetic response.
Antenna technology originally developed to quickly send and receive information through a software-defined military radio may soon be used to transmit ocean data from a wave-powered autonomous surface vehicle. The technology, the lowest-power method for maintaining a satellite uplink, automatically compensates for the movement of the antenna as the boat bobs around on the ocean surface.
In the journal Nature, researchers at Massachusetts Institute of Technology’s Media Lab report a new approach to generating holograms that could lead to color holographic-video displays that are much cheaper to manufacture than today’s experimental, monochromatic displays. The same technique could also increase the resolution of conventional 2-D displays.
Researchers at Chalmers Univ. of Technology have found an effective solution for collecting sunlight for artificial photosynthesis. By combining self-assembling DNA molecules with simple dye molecules, the researchers have created a system that resembles nature's own antenna system.
The first commercial application of computational photography is the so-called light-field camera, which can measure not only the intensity of incoming light but also its angle. However these cameras trade a good deal of resolution for that extra angle information. That is, until now.
Japan's nuclear watchdog formally approved a set of new safety requirements for atomic power plants Wednesday, paving the way for the reopening of facilities shut down since the Fukushima disaster. The new requirements approved by the Nuclear Regulation Authority will take effect on July 8, when operators will be able to apply for inspections.
When it's in flight, there's no roar of engines. It's strangely quiet. And as it crisscrosses the U.S., the spindly plane doesn't use a drop of fuel. Ernest Moniz, who heads the U.S. Department of Energy, praised the efficiency of the Solar Impulse plane at a news conference Monday in Washington, where the plane landed early Sunday morning. He said the solar-powered aircraft highlighted a cleaner energy future for the nation.
Nearly 120 scientists and engineers from around the world are meeting in South Dakota this week to discuss operational and technical issues with collecting images from the Landsat 8 satellite. In February, NASA launched the satellite, which takes images of every inch of the Earth’s surface to see what happens over time, and recently handed over operational control of it to the EROS Center.
This week, Sandia National Laboratories is hosting the seventh annual Western National Robot Rodeo and Capability Exercise, a challenging five-day event that draws civilian and military bomb squad teams from across the country to see who can most effectively defuse dangerous situations with the help of robots. The competition provides an opportunity to practice using robots and new technology in a low-risk, but competitive environment.
More than 2,500 attendees turned out for the 2013 RAPID Conference and Exposition, almost doubling last year’s attendance and reflecting widespread excitement about 3D printing and additive manufacturing, according to event organizer SME. It included attendees from nearly 30 countries and the U.S.
State lawmakers on Tuesday approved legislation that would invest millions of dollars in public and private money in Wisconsin startups despite criticism that the investment targets only limited industries. The bipartisan legislation would create a program that invests $25 million from the state and at least $50 million in private money in young Wisconsin companies
