Xenon could provide protection for the brain after a blow to the head

By - September 9, 2014
Injuries from a blow to the head are a two-stage affair, with the primary injury caused by the initial impact being followed by a secondary injury that develops in the subsequent hours and days. We have seen the development of devices like the Jolt Sensor that are designed to detect the severity of the initial impact, but there is currently no drug treatment for the secondary injury, which is largely responsible for a patient sustaining mental and physical disabilities. Now scientists at Imperial College London have found that xenon gas shows promise as such a treatment. Read More

"Bruise trousers" are designed to let disabled athletes know when they're hurt

By - June 19, 2014
Along with the obvious mobility issues faced by athletes who are unable to walk, they also face another challenge – if they're unable to feel their legs, that means they can't always tell when they've been hurt. Severe bruises or broken bones can simply go unnoticed, until they develop into even more of a problem. That's why a group of students at Imperial College London have invented a set of "bruise trousers" that show such athletes when and where they've received a serious impact below the waist. Read More

Foam-squirting quadcopter becomes a flying 3D printer

By - May 8, 2014 9 Pictures
The swiftlet may not look much different than other little birds, but it has one unique ability – it builds its nest out of its own saliva. Inspired by the swiftlet, scientists at Imperial College London's Aerial Robotics Lab have created a robotic quadcopter that can extrude polyurethane foam while in flight. By targeting where that foam goes, it can build up simple structures, essentially becoming a flying 3D printer. The technology could have some very important applications. Read More

New catalytic converter could make cars cleaner, more fuel efficient and less expensive

By - January 28, 2014
By helping to minimize the hydrocarbons and other pollutants that are emitted in a car's exhaust, catalytic converters serve an important purpose. Because they contain precious metals such as platinum, however, they can also be expensive. Now, a British scientist has developed a new type of converter that should be cheaper, longer-lasting and more effective, plus it should boost the vehicle's fuel efficiency. Read More

Good vibrations lead to efficient excitations in hybrid solar cells

By - November 8, 2013 2 Pictures
Increasing the efficiency of a hybrid solar cell simply by placing it near a source of ambient noise or vibration would be a boon for photovoltaics in urban areas, in the military, or on machinery or transportation. Hybrid organic/inorganic solar cells are already a tempting option over silicon because of their lower cost, but they suffer from their own drawbacks of efficiency. However, new research demonstrates that the piezoelectric qualities of the cells' inorganic layer can be used to boost the overall efficiency of hybrid systems, which is promising for wherever sound and sun are together.
