Looking to nature for their muse, researchers have used a common protein to guide the design of a material that can make energy-storing hydrogen gas. The synthetic material works 10 times faster than the original protein found in water-dwelling microbes, the researchers report in the August 12 issue of the journal Science, clocking in at 100,000 molecules of hydrogen gas every second. This step is just one part of a series of reactions to split water and make hydrogen gas, but the researchers say the result shows they can learn from nature how to control those reactions to make durable synthetic catalysts for energy storage, such as in fuel cells. In addition, the natural protein, an ...

Contact lost with hypersonic glider after launch By JOHN ANTCZAK Associated Press LOS ANGELES (AP) -- An unmanned hypersonic glider developed for U.S. defense research into super-fast global strike capability was launched atop a rocket early Thursday but contact was lost after the experimental craft began flying on its own, the Defense Advanced Research Projects Agency said. There was no immediate information on how much of the mission's goals were achieved. It was the second of two planned flights of a Falcon Hypersonic Technology Vehicle-2. Contact was also lost during the first mission. The small craft is part of a U.S. military initiative to develop technology to respond to ...
"Super" mouse evolves resistance to most poisons

Scientists say that some European house mice have developed resistance to the strongest poisons. German and Spanish mice have rapidly evolved the trait by breeding with an Algerian species from which they have been separate for over a million years. The researchers say this type of gene transfer between different species is highly unusual and normally found in plants and bacteria. They are concerned that this rare form of rapid evolution could herald the spread of new generations of rodents resistant to almost any form of chemical pest control. Warfarin is a drug widely used in medicine as an anticoagulant to prevent the build up of harmful blood clots. It works through inhibiting a ...

Like most forms of renewable energy, solar power still loses points for cost effectiveness. Two Swiss energy pioneers hope to change that with a blow-up solution. Felix Tiefenbacher and Samuel Kutter of Vienna-based Heliovis have seen the future and the future is sausage shaped and inflatable. The prototype is impressive: a 35-metre long tube, two metres in diameter. The final 200-metre long device is due on the market in 2016. The solar innovators have permission to assemble and test their device on the grounds of the Dürnrohr steam power plant near Zwentendorf in Austria. Swissinfo.ch went along for a physics lesson. Tiefenbacher is pleased and annoyed in equal parts. On the plus ...

Using gold as a potential treatment for cancer could become a reality thanks to a combination of imaging techniques. In work published recently in The Royal Society of Chemistry journal Metallomics, researchers at The University of Western Australia and Griffith University's Institute for Glycomics describe how using two imaging techniques allows scientists to see where gold complexes used in potential chemotherapeutic treatments end up in cells. They are also able to monitor the gold's effects on the cells in a non-destructive way. Previous methods for this type of analysis were destructive to the cell. Lead author, Dr Louise Wedlock, who carried out the work while at UWA's ...

US Space weather scientists have predicted that large sun explosion over the last few days could affect communications and global positioning system (GPS) satellites. Weather scientists in the US have warned the users of satellite, telecommunications and electric equipment, due to three explosions from the sun, to be ready for possible disruptions during the next few days. "The magnetic storm that is soon to develop probably will be in the moderate to strong level," said Joseph Kunches, a space weather scientist at the Space Weather Prediction Center, a division of the U.S. National Oceanic and Atmospheric Administration (NOAA). Although solar activities rarely induce massive ...
Dieting forces brain to eat itself, scientists claim

Dieters struggle to lose weight because a lack of nutrition forces their brain cells to eat themselves, making the feeling of hunger even stronger, scientists claim. Like other parts of the body, brain cells begin to eat themselves as a last-ditch source of energy to ward off starvation, a study found. The body responds by producing fatty acids, which turn up the hunger signal in the brain and increase our impulse to eat. Researchers from the Albert Einstein College of Medicine at Yeshiva University in New York said the findings could lead to new scientifically proven weight loss treatments. Tests on mice found that stopping the brain cells from eating themselves – a process known ...

(Reuters) - Scientists have identified an emerging "superbug" strain of salmonella that is highly resistant to the antibiotic Ciprofloxacin, or Cipro, often used for severe salmonella infections, and say they fear it may spread around the world. The strain, known as S. Kentucky, has spread internationally with almost 500 cases found in France, Denmark, England and Wales in the period between 2002 and 2008, according a study in the Journal of Infectious Diseases. French researchers who led the study also looked at data from North America and said reports of infection in Canada and contamination of imported foods in the United States suggest the strain has also reached there. ...
Collision of two moons may have created lunar bulges on one side, report says

LOS ANGELES — Once upon a time, the sky above Earth may have held two moons — until they smashed into each other to create the lunar body we know today. Such a collision early in the solar system's history could explain why the moon is lopsided, and why its far side looks so different from the face we can see, according to a report in Thursday's edition of the journal Nature. Round as it may seem from our vantage point, the moon in fact bulges on one side — the far side, which is packed with high, jagged mountains. That's a more severe surface than the smooth side we see, filled with basins of volcanic rock. The moon was formed about 4.5 billion years ago, after ...

SAN DIEGO — Here in a laboratory perched on the edge of the continent, researchers are trying to construct Life As We Don’t Know It in a thimbleful of liquid. Generations of scientists, children and science fiction fans have grown up presuming that humanity’s first encounter with alien life will happen in a red sand dune on Mars, or in an enigmatic radio signal from some obscure star. But it could soon happen right here on Earth, according to a handful of chemists and biologists who are using the tools of modern genetics to try to generate the Frankensteinian spark that will jump the gap separating the inanimate and the animate. The day is coming, they say, when chemicals ...

Tapping into drivers' brain signals can cut braking distances and avoid car crashes, according to scientists. Researchers at the Berlin Institute for Technology attached electrodes to the scalps of volunteers inside a driving simulator. The system detected the intention to brake, and cut more than 3m (10ft) off stopping distances, the team report in the Journal of Neural Engineering. The team's next aim is to check the system in a series of road tests. The 18 volunteers were asked to keep 20m (66ft) behind the simulated car in front, which braked sharply at random intervals. Scientists used a technique called electroencephalograhy (EEG) to analyse the drivers' brain ...

AN ASTEROID 300 metres in diameter is stalking the Earth. Hiding in the pre-dawn twilight, it has marched in lockstep with our planet for years, all but invisible to our telescopes. The rock is Earth's first confirmed Trojan, which can orbit the sun in either of two gravitational wells along the same orbital path as our planet. From the sun's point of view, these wells lie 60 degrees ahead of and behind the Earth, at Lagrange points where gravitational forces between the sun and the Earth balance out. Trojans are common - Jupiter alone boasts about 5000, and Neptune and Mars each have their own smaller collections. But finding Earth's has proven difficult, because the Lagrange ...
