A team of University of California, Riverside’s Bourns College of Engineering students has developed a titanium dioxide roof tile coating that removes up to 97 percent of smog-causing nitrogen oxides.The students' calculations show that 21 tons of nitrogen oxides would be eliminated daily if tiles on one million roofs...

Researchers at Stanford University say that they used electrical stimulation of retinal cells to produce the same patterns of activity that occur when the retina sees a moving object. They say that this is a step toward restoring natural, high-fidelity vision to blind people.

Using precarious particles called polaritons that straddle the worlds of light and matter, University of Michigan, Ann Arbor, researchers have demonstrated a new, practical and potentially more efficient way to make a coherent laser-like beam. They say that their first-time polariton laser is fueled by...

A team of biomedical engineering students at Johns Hopkins University, Baltimore, MD, designed a lightweight, easy-to-conceal shirt-like garment to deliver life-saving shocks to patients experiencing serious heart problems. The students say their design improves upon a wearable defibrillator system that is...

The natural mechanical properties of natural joints are considered unrivalled. Cartilage is coated with a special layer of lubrication that allows joints to move virtually friction-free, even under high pressure. Using simulations on supercomputers, scientists from Forschungszentrum Jülich in Germany...

A team of engineers at Brown University, Providence, RI, say that they have developed a new biochip sensor that that can selectively measure glucose concentrations in a complex fluid like saliva. This an important step toward a device that could enable diabetics to test their glucose levels...

Inspired by earthworms, which use peristaltic locomotion to wriggle, an engineering student at the University of Cincinnati's College of Engineering and Applied Science used a worm’s contracting and expanding motion to provide a way for gels to freely swim in liquids.

The EU project SARISTU (Smart Intelligent Aircraft Structures) aims to reduce kerosene consumption by six percent, and integrating flexible landing devices into aircraft wings is one step towards that target.

A team of NASA and University of Wyoming scientists has ventured into the Australian bush to send a series of balloons aloft. The balloons will make measurements of a volcanic plume originating from neighboring Indonesia.The campaign, in Australia’s Northern Territory, is part of an effort to...

Technology companies, including Google and Apple, are investing in "smart home" technologies that connect household devices — lighting, security systems, garage-door openers, climate controllers or kitchen appliances — with mobile devices. Research indicates that the global "smart home" industry will...
