Scientists use Silly Putty ingredient to improve batteries

If you see a group of scientists playing with a blob of Silly Putty, they might not be goofing off, they may be working on a technological breakthrough. That turned out to be the case with researchers at the University of California, Riverside Bourns College of Engineering , who have developed a way to use an ingredient in Silly Putty to improve lithium-ion battery life between charges by three times the industry standard.

Color-changing film could revolutionize product development

Whether you're manufacturing cars, phones, sports equipment or pretty much anything else, a key part of the design process involves measuring the amount of mechanical stress experienced by different parts of the product. Thanks to research being conducted at the University of California, Riverside, doing so may soon be much easier. Scientists there have created a film that changes color when subjected to pressure, making it easy to see where objects coated with the film may need reinforcement. Read More

Energy-producing Honda Smart Home gives more than it takes

With homes and light-vehicles accounting for roughly 44 percent of total greenhouse gases emitted in the US, neutralizing these emissions would certainly go a long way towards a clean energy future. What if these sources of pollution could not only be nullified, but play an active role in reducing our environmental footprint? Such is the thinking behind the Honda Smart Home US unveiled last week, which generates enough solar energy to power both car and home, with a little left over to feed back into the grid. Read More

Computer better than a human at telling if you're faking it

A computer-vision system able to detect false expressions of pain 30 percent more accurately than humans has been developed. Authors of the study, titled Automatic Decoding of Deceptive Pain Expressions, believe the technology has the potential for detecting other misleading behaviors and could be applied in areas including homeland security, recruitment, medicine and law.

Biogasoline could be joining biodiesel at the pumps

By now, most people have at least a passing knowledge of biodiesel – it's diesel fuel made from plant or animal oils, as opposed to the more traditional and less eco-friendly petroleum. While it's a good choice for people with diesel-powered vehicles, those of us with gas-burning cars haven't been able to get in on the action ... although that may be about to change. Read More

Distant quasar lights up cosmic web like a neon sign

That the Universe is largely composed of a cosmic web consisting of narrow filaments upon which galaxies and intergalactic gas and dust are concentrated has been known for more than a decade. While a great deal of evidence for this has accumulated, visual evidence has been difficult to find. Astronomers have now photographed what appears to be a segment of a cosmic filament stimulated into fluorescence by irradiation from a nearby quasar. Read More

Implant measures medication levels in bloodstream, in real time

Figuring out how much medication a patient should be taking can be a tricky business. Although things like age and weight are used as guidelines, factors such as the individual person's metabolism can have a marked effect on how effective the drugs are. With that in mind, scientists at the University of California, Santa Barbara have developed an implantable device that provides continuous real-time readings on how much medication is currently in a person's bloodstream.

Toxin-detection system inspired by turkeys

Turkeys may not be everyone's idea of beautiful birds, but they certainly have colorful skin on their heads. What's more, that skin changes color with the animal's mood. Scientists at the University of California, Berkeley, have now copied the process by which those color changes occur, and used it to create a biosensor that could be used to detect airborne toxins.
