The best style and fabrics for COVID-19 face masks

In a new study, researchers found that in the race to stop the spread of COVID-19, a three-layer cloth mask that fits well can...

Scientists design next-generation photodetector

The advanced photodetector could be used in night vision, optical communication, and thermal and medical imaging. Northwestern University researchers have developed a new approach to...

New design makes stretchable electronics perform better under strain

Our bodies send out hosts of signals - chemicals, electrical pulses, mechanical shifts - that can provide a wealth of information about our health. But...

Scientists use a novel ink to 3D print ‘bone’ with living cells

Scientists have worked out how to print bone-like structures using a 3D-printer and a gelatinous 'bath' containing living cells. Scientists from UNSW Sydney have developed...

Pain-free microneedle patch may replace needles for blood draws

No more needles. Blood draws are no fun. They hurt. Veins can burst, or even roll — like they’re trying to avoid the needle, too. Oftentimes, doctors...

Lasers and virtual reality to revolutionize watch-crystal engraving

EPFL engineers teamed up with luxury watchmaker Vacheron Constantin to develop an innovative system that uses lasers to create 3-D sculptures within sapphire watch...

Scientists develop new method to create bioelectronics out of microscopic structures

Bringing together soft, malleable living cells with hard, inflexible electronics can be a difficult task. UChicago researchers have developed a new method to face this...

Scientists develop new graphene nanochannel water filters

When sheets of two-dimensional nanomaterials like graphene are stacked on top of each other, tiny gaps form between the sheets that have a wide...

New smart aerogel could turn air into drinking water

One kilogram of the new material generates enough drinking water to meet a household's daily need, and does not require any external power source. Some...

This laser-steering microrobot could refine minimally invasive surgeries

Robotic engineers from Harvard’s Wyss Institute and John A. Paulson School for Engineering and Applied Science (SEAS) have developed a laser-steering microrobot that can...
