New window into nanoscale chemistry could help improve pollution control, fuel cell technologies

The first-ever glimpse of nanoscale catalysts in action could lead to improved pollution control and fuel cell technologies. Scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory observed catalysts restructuring themselves in response to various gases swirling around them, like a chameleon changing its color to match its surroundings.

Physics may be the furthest thing from the minds of the presidential candidates right now, but a solid grasp of the science behind some of the latest headlines will be critical for the winner.

Physics has a history of intersecting with politics in ways both large and small, from the creation of the atomic bomb to nuclear meltdowns to terrorist methods. And now, with more specialized, high-tech issues to tackle than ever before, it is increasingly important that world leaders have an understanding of the underlying scientific concepts.

When a 1991 cholera outbreak that killed thousands in Peru was traced to plankton blooms fueled by warmer-than-usual coastal waters, linking disease outbreaks to epidemics was a new idea. Now, scientists say, it is a near-certainty that global warming will drive significant increases in waterborne diseases around the world. [ read more ]

A novel photovoltaic technology moves into large-scale production.

In a significant milestone in the deployment of flexible, printed photovoltaics, Konarka, a solar-cell startup based in Lowell, MA, has opened a commercial-scale factory, with the capacity to produce enough organic solar cells every year to generate one gigawatt of electricity, the equivalent of a large nuclear reactor.

A clever flute-playing robot can teach beginners and play in a band.

One of the more whimsical robots presented at BioRob 2008 in Arizona last week, was the latest version of the Waseda Flutist Robot, a robot musician first created in the 1990s. Jorge Solis, a researcher at Waseda University, in Japan, has been working on the robot since 2003, and he and other researchers recently made some important improvements, including adding more than 40 degrees of freedom to its body to make its flute playing more lifelike, and giving it the ability to recognize and interact with other human players. It’s given several performances already. [ read more ]

University of Calgary climate change scientist David Keith and his team are working to efficiently capture the greenhouse gas carbon dioxide directly from the air, using near-commercial technology.

In research conducted at the U of C, Keith and a team of researchers showed it is possible to reduce carbon dioxide (CO2) – the main greenhouse gas that contributes to global warming – using a relatively simple machine that can capture the trace amount of CO2 present in the air at any place on the planet.

“At first thought, capturing CO2 from the air where it’s at a concentration of 0.04 per cent seems absurd, when we are just starting to do cost-effective capture at power plants where CO2 produced is at a concentration of more than 10 per cent,” says Keith, Canada Research Chair in Energy and Environment.

Scientists say they have a working prototype of a fully artificial heart ready for implanting in humans. The device beats almost exactly like the real thing using electronic sensors to regulate heart rate and blood flow. Developers Carmat now need approval from the French authorities before pushing ahead with clinical trials. But heart experts warned it was still early days as previous attempts to create a fully artificial heart had failed during human testing. [ read more ]

Scientists have developed a better way to identify fingerprints on bullets and fragments of explosives.

Fingerprints are crucial evidence in many criminal investigations because they can tie a suspect to the scene of a crime with almost indisputable accuracy. Now crime-scene investigators have a new technique for finding fingerprints left on metals, like the cartridge from a spent bullet or fragments of an improvised explosive device, even if the perpetrator tries to wash the evidence clean.

MIT researchers gauge the progress of malaria using a novel imaging technique.

Bridging physics, engineering, and microbiology, researchers at MIT have measured the frequency at which red blood cells vibrate and have shown that those frequencies reflect the health of the cells. The research could lead to better medical diagnostics. [ read more ]

Research shows how insects use trapped oxygen to breathe underwater

Hundreds of insect species spend much of their time underwater, where food may be more plentiful. MIT mathematicians have now figured out exactly how those insects breathe underwater.

By virtue of their rough, water-repellent coat, when submerged these insects trap a thin layer of air on their bodies. These bubbles not only serve as a finite oxygen store, but also allow the insects to absorb oxygen from the surrounding water.
