Perfect Crystals Grown by Cancelling Out Gravity on Earth

willatnewscientist writes "Researchers in the Netherlands and Japan have found a way to grow perfect crystals in 'zero gravity' here on Earth. By exploiting the way a powerful magnet influences diamagnetic materials they have been able to grow protein crystals without the defects normally introduced as a result of gravity (The same trick has been used to levitate a frog before). Normally, such crystals are grown in space, such as aboard the International Space Station."
