Devices are now more efficient at converting heat and light into electricity and are stable in air for the first time
A new form of neuromorphic synapse operates just like its biological counterpart while being faster and more energy efficient
Ultrafine aerosol particles smaller than 50 nm in size produced by human activities were previously thought to be too small to affect cloud formation but they do in fact fuel powerful storms and influence weather
New device is much lighter and less cumbersome than existing fibre-optical-waveguide systems
Simple folding strategy could easily work for other battery electrode materials too
New flexible, wireless device can alert the wearer if glucose levels become too high
New structures could be integrated into smart buildings, cars, large-screen displays and potentially many other technologies
Metagenomic analyses of large groups of microorganisms shed more light on how bacteria and other microbes behave when exposed to nanomaterials
New DNA-based device can be driven by electrical fields alone and can move 100,000 times faster in solution than other such machines
It can also detect an object’s position in space
