'Fool's gold' may be valuable after all

In a breakthrough new study, scientists and engineers at the University of Minnesota have electrically transformed the abundant and low-cost non-magnetic material iron sulfide, also known as "fool's gold" or pyrite, into ...

Scientists find upper limit for the speed of sound

A research collaboration between Queen Mary University of London, the University of Cambridge and the Institute for High Pressure Physics in Troitsk has discovered the fastest possible speed of sound.

Better energy harvesting with 'law-breaking' device

If you take an object and set it out in the sun, it will begin to warm up. This is because it is absorbing energy from the sun's rays and converting that energy to heat. If you leave that object outside, it will continue ...

Stacking and twisting graphene unlocks a rare form of magnetism

Since the discovery of graphene more than 15 years ago, researchers have been in a global race to unlock its unique properties. Not only is graphene—a one-atom-thick sheet of carbon arranged in a hexagonal lattice—the ...

Say hello to the toughest material on Earth

Scientists have measured the highest toughness ever recorded, of any material, while investigating a metallic alloy made of chromium, cobalt, and nickel (CrCoNi). Not only is the metal extremely ductile—which, in materials ...
