The story of information
Physicists explore new prediction techniques
The laws of optics underpin the visual effects we see in the cinema
Subtle physics is needed to explain many of nature’s mysterious atmospheric optical phenomena, including rainbows, ice-crystal haloes and the much rarer fog-bows, dew-bows and glories.
Optical tricks that have given butterflies, beetles and other creatures an evolutionary advantage are beginning to teach physicists a thing or two about advanced photonics
US physicists have made atoms behave like the electrons in a superconductor
Scientists have made a device that detects viruses when used with an atomic force microscope
