Tests may lead to doubling of fuel cell life
May 23, 2013 | Comments
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.

Expressly unfit for the laboratory
June 19, 2013 4:39 pm | CommentsA 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.
GTRI agile aperture antenna technology tested on autonomous ocean vehicle
June 19, 2013 4:28 pm | CommentsAntenna 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.
Cheap, color, holographic video
June 19, 2013 4:13 pm | by Larry Hardesty, MIT News Office | CommentsIn 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.
DNA constructs antenna for solar energy
June 19, 2013 8:11 am | CommentsResearchers 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.
Multiview 3-D photography made simple
June 19, 2013 7:57 am | by Larry Hardesty, MIT News Office | CommentsThe 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 formally OKs new nuke safety requirements
June 19, 2013 7:48 am | by MARI YAMAGUCHI - Associated Press - Associated Press | CommentsJapan'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.
Solar plane to help ground energy use
June 19, 2013 1:01 am | by Seth Borenstein, AP Science Writer | CommentsWhen 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.
Scientists discuss new photo-taking satellite
June 19, 2013 12:52 am | by Dirk Lammers, Associated Press | CommentsNearly 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.
Sandia Labs hosts annual Robot Rodeo
June 19, 2013 12:46 am | CommentsThis 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.
Rapid prototyping conference breaks past attendance records
June 19, 2013 12:11 am | CommentsMore 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.
Wisconsin lawmakers approve venture capital bill
June 18, 2013 7:52 pm | by KEVIN WANG - Associated Press - Associated Press | CommentsState 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
Insaco supports “green”
June 18, 2013 2:24 pm | CommentsSince 1947, Insaco, Quakertown, Pa., has provided precision machining and polishing of fabricated parts from most technical ceramics, sapphire, glass and quartz. The company machines these materials to very precise tolerances—many times measured in millionths of an inch—for dimension, flatness, wedge and roundness or cylindricity.
Stop hyperventilating, say energy-efficiency researchers
June 18, 2013 2:10 pm | CommentsA single advanced building control now in development could slash 18%—tens of thousands of dollars—off the overall annual energy bill of the average large office building, with no loss of comfort, according to a report by researchers at the Pacific Northwest National Laboratory.
Printing tiny batteries
June 18, 2013 1:52 pm | Comments3-D printing can now be used to print lithium-ion microbatteries the size of a grain of sand. The printed microbatteries could supply electricity to tiny devices in fields from medicine to communications, including many that have lingered on laboratory benches for lack of a battery small enough to fit the device, yet provide enough stored energy to power them.
World’s most powerful microscope ready for research
June 18, 2013 1:26 pm | CommentsThe world’s most powerful microscope, which resides in a specially constructed room at the Univ. of Victoria, has now been fully assembled and tested, and has a lineup of scientists and businesses eager to use it. The seven-ton, 4.5-m-tall scanning transmission electron holography microscope, the first such microscope of its type, came to the university in parts last year.
