Nearly two years following Robert Dziekanski's death at Vancouver International Airport after being shot by Royal Canadian Police with a TASER, a commission investigating Canadian law enforcement's use of such "conducted energy weapons" supports their continued use, as long as this accompanies an overhaul of how and when these weapons are used. (Dziekanski's 2007 encounter with police can be viewed on YouTube.) [More]

Scientists have created a transparent form of aluminum by bombarding the metal with the world's most powerful soft X-ray laser. 'Transparent aluminum' previously only existed in science fiction, featuring in the movie Star Trek IV, but the real material is an exotic new state of matter with implications for planetary science and nuclear fusion. The aluminum is nearly invisible to extreme ultraviolet radiation.

Dye-sensitized solar cells are expected to power Air Force unmanned aerial vehicles in the future because they are an optimum energy harvesting source that may lead to longer flight times without refueling.

A drug similar to one used in clinical trials for treatment of rheumatoid arthritis and psoriasis has been found to rescue memory in mice exhibiting Alzheimer's symptoms.
