In a promising result for the success of vaccines against COVID-19, rhesus macaque monkeys infected with the human coronavirus SARS-CoV-2 developed protective immune responses that might be reproduced with a vaccine.

Laser beams are used to change material properties precisely. However, the underlying processes generally happen unimaginably fast and at such a small scale that they have so far eluded direct observation. Researchers have now managed to film, for the first time, the laser transformation of a crystal structure with nanometre resolution and in slow motion in an electron microscope.

A new study suggests that a lot of people might be going through life with symptoms that resemble concussion - a finding supporting researchers' argument that athletes recovering from a brain injury should be assessed and treated on a highly individualized basis.

Using water samples and environmental data gathered over 48 hours or less, engineers have developed a new predictive technique for forecasting coastal water quality. It could be used to keep tabs on otherwise unmonitored coastal areas, a critical step in protecting public health and the ocean economy.
