New forms of highly efficient, flexible nanogenerator technology (November 12, 2010) -- Can a heart-implanted micro-robot operate permanently? Can cell phones and tiny robots implanted in the heart operate without having their batteries charged? Such advances may be possible in the near future, thanks to new forms of highly efficient, flexible nanogenerator technology. ... > full story
Formation of bulge on far side of moon explained (November 12, 2010) -- A new study shows that the lunar far side highlands may be the result of tidal forces acting early in the moon's history when its solid outer crust floated on an ocean of liquid rock. ... > full story
All-optical transistor: Controling the flow of light with a novel optical transistor (November 12, 2010) -- Researchers have discovered a method for coupling photons and mechanical vibrations that could have numerous applications in telecommunications and quantum information technologies. ... > full story
Scientists ping key material in sonar, closes gap on structural mystery (November 12, 2010) -- Using a neutron beam as a probe, researchers have begun to reveal the crystal structure of a compound essential to technologies ranging from sonar to computer memory. Their recent work provides long-sought insight into just how a widely used material of modern technology actually works. ... > full story
'Toxic toy crisis' requires fresh solutions, experts say (November 12, 2010) -- Manufacturer recalls of toys, promotional drinking glasses, and other children's products constitute an ongoing "toxic toys crisis" that requires banning potentially harmful ingredients in these products and other changes in policy and practices, a new analysis concludes. ... > full story
Brass devices in plumbing systems can create serious lead-in-water problems (November 12, 2010) -- A new research study highlights problems with some brass products in plumbing systems that can leach high levels of lead into drinking water, even in brand new buildings -- and suggests that such problems may often go undetected. ... > full story
New ultra-clean nanowires have great potential in solar cell technology and electronics (November 12, 2010) -- New ultra-clean nanowires will have a central role in the development of new high-efficiency solar cells and electronics on a nanometer scale. ... > full story
New highly stable fuel-cell catalyst gets strength from its nano core (November 12, 2010) -- Scientists have developed a new electrocatalyst that uses a single layer of platinum and minimizes its wear and tear while maintaining high levels of reactivity during tests that mimic stop-and-go driving. The research may greatly enhance the practicality of fuel-cell vehicles and may also be applicable for improving the performance of other metallic catalysts. ... > full story
Detailed dark matter map yields clues to galaxy cluster growth (November 12, 2010) -- Astronomers using NASA's Hubble Space Telescope took advantage of a giant cosmic magnifying glass to create one of the sharpest and most detailed maps of dark matter in the universe. Dark matter is an invisible and unknown substance that makes up the bulk of the universe's mass. ... > full story
Mind is a frequent, but not happy, wanderer: People spend nearly half their waking hours thinking about what isn’t going on around them (November 12, 2010) -- People spend 46.9 percent of their waking hours thinking about something other than what they're doing, and this mind-wandering typically makes them unhappy. So says a study that used an iPhone web app to gather 250,000 data points on subjects' thoughts, feelings, and actions as they went about their lives. ... > full story
Softening crystals without heat: Using terahertz pulses to manipulate molecular networks (November 12, 2010) -- As if borrowing from a scene in a science fiction movie, researchers in Japan have successfully developed a kind of tractor beam that can be used to manipulate the network of the molecules. In a new paper, the team has demonstrated a technique using terahertz pulses that could have broad applications in the chemical and pharmaceutical industries. ... > full story
Graphene's strength lies in its defects (November 11, 2010) -- Materials engineers have found that the juncture at which graphene sheets meet does not compromise the material's strength. These so-called grain boundaries are so strong, in fact, that the sheets are nearly as strong as pure graphene. The trick lies in the angles at which the individual sheets are stitched together. ... > full story
