Unprecedented plasma lensing for high-intensity lasers

High-power laser pulses focused to small spots to reach incredible intensities enable a variety of applications, ranging from scientific research to industry and medicine. At the Berkeley Lab Laser Accelerator (BELLA) Center, ...

Porous materials unfavorable for coronavirus survival

As COVID-19 spreads via respiratory droplets, researchers have become increasingly interested in the drying of droplets on impermeable and porous surfaces. Surfaces that accelerate evaporation can decelerate the spread of ...

Science of building sandcastles finally understood

Water vapor from ambient air will spontaneously condense inside porous materials or between touching surfaces. But with the liquid layer being only a few molecules thick, this phenomenon has lacked understanding, until now.

Solving the mysteries of water and air underground

Stand outside and look underneath your feet. There, perhaps under some grass, is the soil. On a dry day, all the spaces in the soil are filled with air. And some distance further down, those spaces are entirely water. So ...

New test strip preserves clues that blood tests often miss

A new synthetic paper for finger prick blood tests could provide accurate point-of-care diagnostics for cancer, COVID-19 and other serious diseases. Researchers at KTH Royal Institute of Technology say the innovation allows ...
