Metalens with artificial muscle simulates (and goes way beyond) human-eye and camera optical functions

Thin, flat structure promises to revolutionize eyeglasses, cameras, microscopes, and augmented and virtual-reality optics

A metalens (made of silicon) mounted on a transparent, stretchy polymer film, without any electrodes. The colorful iridescence is produced by the large number of nanostructures within the metalens. (credit:Harvard SEAS)

Measuring deep-brain neurons’ electrical signals at high speed with light instead of electrodes

“We will be able to watch a neural computation happen ... a step toward understanding what a thought or a feeling actually is.” --- Prof. Edward Boyden

Superconducting ‘synapse’ could enable powerful future neuromorphic supercomputers

Fires 200 million times faster than human brain, uses one ten-thousandth as much energy

NIST's artificial synapse ,designed for neuromorphic computing, mimics the operation of a switch between two neurons. One artificial synapse is located at the center of each X. The thick black vertical lines are electrical probes for testing. This chip is 1 square centimeter in size. (credit: NIST)

Cancer ‘vaccine’ eliminates all traces of cancer in mice

Bodywide immune stimulation without adverse side effects

Effects of in situ vaccination with CpG and anti-OX40. Left: Mice genetically engineered to spontaneously develop breast cancers in all 10 of their mammary pads were injected into the first arising tumor (black arrow) with either a vehicle (inactive fluid) (Left) or with CpG and anti-OX40 (right). Pictures were taken on day 80. (credit: Idit Sagiv-Barfi et al./ Sci. Transl. Med.)
