Researchers have created the first three-dimensional topological insulator for light. A judiciously placed screw dislocation allows optical signals to wind around the surface of a synthetic lattice while keeping it protected from scattering.
A newly-developed 3D printing technique could be used to cost-effectively produce customized electronic 'machines' the size of insects, which enable advanced applications in robotics, medical devices and others.
Using their novel liquid biopsy platform, the researchers could detect brain cancer from just five microliters of blood serum, and they could distinguish it from breast, lung and colorectal cancer with 100% specificity and sensitivity.
Scientists have identified a new treatment that improves recovery after a stroke in an animal model and offers new opportunities for treating neurological disorders.
Researchers show that the carrier concentration and conductivity in p-type monovalent copper semiconductors can be significantly enhanced by adding alkali metal impurities.
Researchers showed how to use laser beam interference to construct chiral structures. By using computer simulations, they were able to predict the final light pattern and optical radiation force distribution of any collection of light sources.
