Researchers create design for nanometer-scale material that can speed up, squeeze light

(Phys.org) —In a process one researcher compares to squeezing an elephant through a pinhole, researchers at Missouri University of Science and Technology have designed a way to engineer atoms capable of funneling light through ultra-small channels.

Scientists advance important microscopic technique for biomedical research

Scientists at TU Delft have made an important advancement in a new microscopic technique that is widely used in medical research. They demonstrate what the resolution of this localisation microscopy is and how the best resolution can be achieved as quickly as possible. This week their findings are being published online in the scientific journal Nature Methods.
