Novel 3D Printing method embeds sensing capabilities within Robotic Actuators

Soft robots that can sense touch, pressure, movement and temperature. Inspired by our bodies’ sensory capabilities, researchers have developed a platform for creating soft robots with embedded sensors that can sense movement, pressure, touch, and even temperature. Researchers at Harvard University have built soft robots inspired by nature that can crawl, swim, grasp delicate objects and even assist a beating heart, but none of these devices has been able to sense and respond to the world around them.

Inspired by our bodies’ sensory capabilities, researchers at the Harvard John A...

Science continues to peel away layers of the skin microbiome to reveal its protective properties. University of California San Diego School of Medicine researchers report a potential new role for some bacteria on the skin: protecting against cancer. “We have identified a strain of Staphylococcus epidermidis, common on healthy human skin, that exerts a selective ability to inhibit the growth of some cancers,” said Richard Gallo, MD, PhD, Distinguished Professor and chair of the Department of Dermatology at UC San Diego School of Medicine...

Advance paves the way for the design of transmembrane proteins with useful, new functions. It is now possible to create complex, custom-designed transmembrane proteins from scratch, scientists report this week. The advance, led by molecular engineers at the University of Washington Institute for Protein Design, will enable researchers to create transmembrane proteins not found in nature to perform specific tasks.

In the living world, transmembrane proteins are found embedded in the membrane ...

This knotted skyrmion may provide insight into a stable ball of plasma that could enhance future fusion reactors. Scientists at Amherst College and Aalto University have created, for the first time a 3D skyrmion in a quantum gas. The skyrmion was predicted theoretically over 40 years ago, but only now has it been observed experimentally.

In an extremely sparse and cold quantum gas, the physicists have created knots made of the magnetic moments, or spins, of the constituent atoms. The knots exhibit many of the characteristics of ball lightning, which some scientists believe to consist of tangled streams of electric currents...
