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.

Cockroaches quickly lose sweet tooth to survive
May 23, 2013 11:04 pm | by Malcolm Ritter, AP Science Writer | CommentsFor decades, people have been getting rid of cockroaches by setting out bait mixed with poison. But in the late 1980s, in an apartment test kitchen in Florida, something went very wrong. A killer product stopped working. Cockroach populations there kept rising. Mystified researchers tested and discarded theory after theory until they finally hit on the explanation.
NASA head views progress on asteroid lasso mission
May 23, 2013 10:59 pm | by Alicia Chang, AP Science Writer | CommentsSurrounded by engineers at the Jet Propulsion Laboratory in Southern California, NASA chief Charles Bolden on Thursday inspected a prototype spacecraft engine that could power an audacious mission to lasso an asteroid and tow it closer to Earth for astronauts to explore. Once relegated to science fiction, ion propulsion is preferred for deep space cruising because it's more fuel-efficient.
New filtration material could make petroleum refining cheaper, more efficient
May 23, 2013 10:55 pm | CommentsA newly synthesized material might provide a dramatically improved method for separating the highest-octane components of gasoline. These components are expensive to isolate. Created in the laboratory of Jeffrey Long, professor of chemistry at the University of California, Berkeley, the material is a metal-organic framework, or MOF, which can be imagined as a sponge with microscopic holes.
Cradle turns smartphone into handheld biosensor
May 23, 2013 10:49 pm | by Liz Ahlberg, University of Illinois | CommentsUniversity of Illinois at Urbana-Champaign researchers have developed a cradle and app for the iPhone that uses the phone’s built-in camera and processing power as a biosensor to detect toxins, proteins, bacteria, viruses and other molecules. Having such sensitive biosensing capabilities in the field could enable on-the-spot tracking of groundwater contamination, or provide immediate and inexpensive medical diagnostic tests.
Scientists announce top 10 new species
May 23, 2013 2:18 pm | CommentsAn amazing glow-in-the-dark cockroach, a harp-shaped carnivorous sponge and the smallest vertebrate on Earth are just three of the newly discovered species selected by the International Institute for Species Exploration at Arizona State University to be recognized as the top 10 of 2012. The announcement comes with a call to discover, in the next 50 years, what are thought to be 10 million undiscovered species on Earth.
Engineer helps pioneer flat spray-on optical lens
May 23, 2013 2:10 pm | CommentsA University of British Columbia engineer and a team of U.S. researchers have made a breakthrough utilizing spray-on technology that could revolutionize the way optical lenses are made and used. Nearly all lenses—whether in an eye, a camera, or a microscope—are presently curved, which limits the aperture, or amount of light that enters. The new spray-on lens is flat, and can be affixed to a glass slide.
Bacterium from Arctic offers clues about life on Mars
May 23, 2013 2:04 pm | CommentsThe temperature in the permafrost on Ellesmere Island in the Canadian high Arctic is nearly as cold as that of the surface of Mars. So the recent discovery by a McGill University led team of scientists of a bacterium that is able to thrive at -15 C, the coldest temperature ever reported for bacterial growth, is exciting. The bacterium offers clues about some of the necessary preconditions for microbial life on Mars.
Scientists develop powerful method for finding therapeutic antibodies
May 23, 2013 1:59 pm | CommentsScientists at The Scripps Research Institute have devised a powerful new technique for finding antibodies that have a desired biological effect. Antibodies, which can bind to billions of distinct targets, are already used in many of the world’s best-selling medicines, diagnostics, and laboratory reagents. The newly reported technique should greatly speed the process of discovering such products.
Study reveals active site of enzyme linked to stuttering
May 23, 2013 12:48 pm | CommentsScientists from the SLAC National Accelerator Laboratory have determined the 3D structure of the chemically active part of an enzyme involved in stuttering. While the discovery is not likely to lead to a cure for stuttering any time soon, it is welcome news to scientists who have been studying this enzyme, known as "uncovering enzyme" or UCE, for decades.
Cell phone technology helps horses recover from surgery
May 23, 2013 12:30 pm | CommentsTechnology that’s used in smartphones and other electronic devices also is being used by veterinarians at the University of Illinois to help horses recover safely from anesthesia. The technology, known as accelerometers, are portable data recorders that capture information on motion, vibration, and impact
Crystals melt when they're cooled
May 23, 2013 8:57 am | CommentsGrowing thin films out of nanoparticles in ordered, crystalline sheets would be a boon for materials researchers, but the physics is tricky because particles of that size don’t form crystals the way individual atoms do. Using bigger particles as models, physicists have predicted some unusual properties of nanoparticle crystal growth.
Researchers explain magnetic field misbehavior in solar flares
May 23, 2013 8:39 am | CommentsWhen a solar flare filled with charged particles erupts from the sun, its magnetic fields sometimes break a widely accepted rule of physics. The flux-freezing theorem dictates that the magnetic lines of force should flow away in lock-step with the particles, whole and unbroken. Instead, the lines sometimes break apart and quickly reconnect in a way that has mystified astrophysicists.
Doctors rescue Ohio boy by "printing" an airway tube
May 23, 2013 8:26 am | by Marilynn Marchione, AP Chief Medical Writer | CommentsIn a medical first, doctors used plastic particles and a 3D laser printer to create an airway splint to save the life of a baby boy who used to stop breathing nearly every day. Because of a birth defect, the Kaiba Gionfriddo’s airway kept collapsing, causing his breathing to stop and often his heart, too. Doctors in Michigan had been researching artificial airway splints but had not implanted one in a patient yet.
U.S. health care: Does more spending yield better health?
May 23, 2013 8:20 am | CommentsHealth care spending is much higher for older Americans than for younger adults and children, on average, and analysts have said that increasing spending leads to longer life expectancy. But new research from the University of Michigan indicates that aging populations could view things differently.
Innovation could bring flexible solar cells, transistors
May 23, 2013 8:07 am | CommentsResearchers have created a new type of transparent electrode that might find uses in solar cells, flexible displays for computers and consumer electronics, and future "optoelectronic" circuits for sensors and information processing. The electrode is made of silver nanowires covered with a material called graphene, an extremely thin layer of carbon.
