Inspired by the coats of fur on some animals, researchers at MIT have developed a flexible skin-like material covered in thousands of tiny magnetic hairs that can move in varying directions in the presence of a magnetic field. That might not seem particularly useful, until MIT points out that the new material can be used to control how liquids move across its surface, even causing water to flow against the pull of gravity.
