Foam-squirting quadcopter becomes a flying 3D printer

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 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

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.

Imperial College develops cancer-sniffing Intelligent Knife

Dr. Zoltan Takats of the Imperial College London has developed one very sharp knife – and we're not referring to its keen edge. The Intelligent Knife (iKnife) is equipped with a nose and a brain that can sniff out cancer as it cuts. Using a mass spectrometer to detect chemical profiles associated with tumors, it enables instant identification of cancerous tissue and helps surgeons to make sure that all of a tumor has been removed.
