Freezing magnetic monopoles

Magnetic monopoles, entities with isolated north or south magnetic poles, weren't supposed to exist. If you try to saw a bar magnet in half, all you succeed in getting are two magnets, each with a south and north pole. In recent years, however, the existence of monopoles, at least in the form of 'quasiparticles' consisting of collective excitations among many atoms, has been predicted and demonstrated in the lab. Now Stephen Powell, a scientist at the Joint Quantum Institute, has sharpened the theoretical framework under which monopoles can operate.

Gecko feet hold clues to creating bandages that stick when wet (w/video)

Scientists already know that the tiny hairs on geckos' toe pads enable them to cling, like Velcro, to vertical surfaces. Now, University of Akron researchers are unfolding clues to the reptiles' gripping power in wet conditions in order to create a synthetic adhesive that sticks when moist or on wet surfaces.

How geckos cope with wet feet

Geckos are remarkable little creatures, clinging to almost any dry surface, and Alyssa Stark, from the University of Akron, USA, explains that they appear to be equally happy scampering through tropical rainforest canopies as they are in urban settings.
