Robotic lab on wheels offers safe, fast and accurate COVID-19 testing

A state-of-the-art diagnostic van can test up to 2,000 people a day, return results within 45 minutes with a very high sensitivity( limit of detection of 150 copies/mL), and reduces contact risks.

Lessons in low-light photosynthesis

?Understanding antennae-like phycobilisomes, and the complex mechanisms of photosynthesis in organisms such as red algae may be key to low-light artificial photosynthesis.

Airborne sensors inspired by seeds

Imagine floating fleets of small-scale, low energy fliers that can monitor pathogens or particulate matter in the air. Seeds have planted new inspiration for scientists who are trying to emulate their ability to travel long distances in freefall.The geometries of seeds combine high drag forces an...

An ultrasensitive, liquid metal-based e-skin motion sensor

An electronic skin with cutting-edge sensitivity tracking a broad range of body motion has been created using liquid metal and a rigid nacre-inspired chromium-copper and silver underlayer.
