Materials with magnetic nanostructures have a wide range of potential applications. One area is so-called spintronics, with devices that encode information in magnetic domains. These magnetic bits can be written, read and erased in a more energy-efficient way than bits in current

Scientists at Nanyang Technological University in Singapore have discovered a surprisingly simple way to create exotic light structures called optical skyrmions using a 200-year-old optical effect known as the Poisson spot. Instead of relying on expensive, highly engineered mater

Within every muscle of every living species with a backbone, a protein called myosin tugs on a partner protein to generate a muscle contraction. This function, discovered in mammals a century ago, has been presumed by scientists to operate the same way among birds, reptiles, amph

Man-made substances surround us everywhere in our daily lives. According to the current understanding of the "Planetary Boundaries" framework, the carrying capacity for so-called novel entities—which include chemicals, microplastics, and nanomaterials—is considered to have been e
