A breakthrough with amazing potential.
Ultra-lightweight materials are an incredibly cool area of materials science, bringing us crazy substances like aerogel. And now, for the first time, scientists have produced a metal that’s so light it can balance on the fluff of a dandelion. Here’s why this material is revolutionary — and how it’s made…

A123’s batteries will make lithium-ion technology practical for the auto industry. Instead of cobalt oxide, they use an electrode material made from nanoparticles of lithium iron phosphate modified with trace metals. The resulting batteries are unlikely to catch fire, even if crushed in an accident. They are also much hardier than conventional lithium-ion batteries: A123 predicts that they will last longer than the typical lifetime of a car.

Balancing risk and reward
A new paper in Medical Hypotheses suggests that very big cash prizes could specifically be targeted to stimulate ‘revolutionary’ science. Usually, prizes tend to stimulate ‘applied’ science — as in the most famous example of Harrison’s improved clock solving the ‘longitude’ problem. But for prizes successfully to stimulate revolutionary science the prizes need to be three key elements. Details after the jump.
