For over 30 years, materials scientists have been able to coat metals with layers of organic compounds only a single molecule thick; these ultra-thin coatings are used in microelectronics, medicine and biosensing. However, so far all of these rely on a bond between the metal and sulfur, which can be easily broken by heat or […]

According to a new study, humans are not very good at determining whether someone’s face is expressing real pain (e.g. from having one’s arm immersed in cold water) versus faked pain. Even after training, humans got it right only 55 per cent of the time, just slightly better than random chance. By contrast, image recognition […]
