A violation of one of the oldest empirical laws of physics has been observed by scientists at the University of Bristol. Their experiments on purple bronze, a metal with unique one-dimensional electronic properties, indicate that it breaks the Wiedemann-Franz Law.

Smart glass can change color or even go from opaque to transparent with just the flick of a switch. Indium tin oxide is used as an electrical contact in many of these 'electrochromic' devices because it is both transparent to visible light and a good conductor of electricity. But indium and tin are both becoming increasingly expensive as the global supply diminishes. Researchers have now shown that carbon could be the perfect replacement.

Bacteria use various appendages to move across surfaces prior to forming multicellular bacterial biofilms. Some species display a particularly jerky form of movement known as "twitching" motility, which is made possible by hairlike structures on their surface called type IV pili, or TFP.
