Researchers have developed a new way to image the brain with unprecedented resolution and speed. Using this approach, they can locate individual neurons, trace connections between them, and visualize organelles inside neurons, over large volumes of brain tissue. The new...

For the first time, researchers performed computational logic operations with a liquid-crystal-based chemical device using electric fields and ultraviolet light.1 The device and the methods used open up research possibilities that include low-power, high-performance computer chips.

For the last 30 years or so, many with severe bladder issues have been treated with stimulators that send an electric current to the nerve that controls the bladder. Such implants improve incontinence and overactive bladder, but they also can...

A team at the University of Lyon has developed a light-scattering method that maps out the mechanical properties of a tumor’s cellular structure as well as its internal fluids, revealing changes due to chemotherapy treatment. The technique could be used...

A team of researchers at Tel Aviv University in Israel has developed a new multiphoton microscopy tool, known as Pysight, for rapid 2D and 3D imaging of the brain and other tissues. Among other things, the team hopes that the...

Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new integrated photonics platform that can store light and electrically control its frequency (or color) in an integrated circuit. The platform draws inspiration...

The visual system of Xenos peckii, an endoparasite of paper wasps, demonstrates distinct benefits for high sensitivity and high resolution, differing from the compound eyes of most insects. Inspired by their unique features, a KAIST team developed an ultrathin digital...

Researchers at the University of Oxford, Imperial College London and the National Physics Laboratory, U.K., have demonstrated strong coupling between light and high-frequency acoustic vibrations in a silica microresonator. The team believes the work—which achieves a long-standing goal in optomechanics—could...

For the first time, MIT researchers have shown that nerves made to express proteins that can be activated by light can produce limb movements that can be adjusted in real-time, using cues generated by the motion of the limb itself....

Using a plasmonic nanostructure, researchers at the University of Central Florida (UCF) have devised a way to hide information on the surface of a material, so that it is only visible through an IR lens or camera that is tuned...
