Researchers at the University of Tokyo have found a way to enhance the sensitivity of existing quantitative phase imaging so that all structures inside living cells can be seen simultaneously, from tiny particles to large structures. This artistic representation of the technique shows pulses of sculpted light (green, top) traveling […]

A team of international researchers, led by Huanyu “Larry” Cheng, Dorothy Quiggle Career Development Professor in Penn State’s Department of Engineering Science and Mechanics, has developed a self-powered, stretchable system that will be used in wearable health-monitoring and diagnostic devices.

A DLP-printed LCE concept device of a spinal cage with a porous lattice architecture. Biological tissues have evolved over millennia to be perfectly optimized for their specific functions. Take cartilage as an example. It’s a compliant, elastic tissue that’s soft enough to cushion joints, but strong enough to resist compression […]

Researchers from the RIKEN Center for Advanced Photonics and collaborators have discovered that terahertz radiation, contradicting conventional belief, can disrupt proteins in living cells without killing the cells. This finding implies that terahertz radiation, which was long considered impractical to use, may have applications in manipulating cell functions for the […]

New technique may enable speedy, on-demand design of softer, safer neural devices. Credit: Courtesy of the researchers Technique may enable speedy, on-demand design of softer, safer neural devices. The brain is one of our most vulnerable organs, as soft as the softest tofu. Brain implants, on the other hand, are […]

The golden color illustrates the deposition of biocompatible polymers on two genetically targeted neurons at right, sparing neighboring cells. The selective deposition of these polymers, which can be electrically insulating or conductive, makes it possible to modulate target cell properties in living tissues and animals. Blue diamond particles represent the […]

A bandage changed color from green to yellow, and from green to red, in the presence of increasing concentrations of drug-sensitive (DS) and drug-resistant (DR) E.coli, respectively.
