A stroke in a baby -- even a big one -- does not have the same lasting impact as a stroke in an adult. A study found that a decade or two after a 'perinatal' stroke damaged the left 'language' side of the brain, affected teenagers and young adults used the right sides of their […]
A new ultrathin, elastic display that fits snugly on the skin can show the moving waveform of an electrocardiogram recorded by a breathable, on-skin electrode sensor. Combined with a wireless communication module, this integrated biomedical sensor system -- called 'skin electronics' -- can transmit biometric data to the cloud.
People and other animals sicken and die if they are deprived of sleep, but why is sleep so essential? Psychiatrists proposed the 'synaptic homeostasis hypothesis' (SHY) in 2003. This hypothesis holds that sleep is the price we pay for brains that are plastic and able to keep learning new things. A few years ago, they […]
In popular culture, asteroids play the role of apocalyptic threat, get blamed for wiping out the dinosaurs -- and offer an extraterrestrial source for mineral mining. But for one researcher, asteroids play an entirely different role: that of time capsules showing what molecules originally existed in our solar system. Having that information gives scientists the […]
Scientists have completed the first major material survey and study of the Musee national Picasso-Paris' Pablo Picasso bronzes using portable instruments. They used the instruments and a database of alloy 'fingerprints' to non-invasively analyze a group of 39 bronzes and 11 painted sheet metal sculptures, revealing new details about the modern master's art.
Scientists have used multiple modes of light to uncover details hidden beneath the visible surface of Pablo Picasso's painting 'La Miséreuse accroupie', a major work from the artist's Blue Period. The researchers found images connected to other works by Picasso as well as a landscape -- likely by another Barcelona painter -- underneath Picasso's painting.
A new study illuminates the biology that guides behavior across different stages of life in worms, and suggests how variations in specific neuromodulators in the developing nervous system may lead to occasional variations.
