Today's physics/chemistry headlines from the sources selected by our team:

Electrons with no mass acquire a mass in the presence of a high magnetic field
An international team of researchers have for the first time, discovered that in a very high magnetic field an electron with no mass can acquire a mass. Understanding why elementary particles e.g. electrons, photons, neutrinos have a mass is a fundamental question in Physics and an area of intense debate. This discovery by Prof Stefano Sanvito, Trinity College Dublin and collaborators in Shanghai was published in the prestigious journal Nature Communications this month.

Photographing sneezes at high speed may help find ways to reduce spread of disease
(Phys.org)—A team of researchers at MIT led by Lydia Bourouiba has discovered some new properties of sneeze clouds by photographing them with high speed cameras and then studying the footage. In their paper published in the New England Journal of Medicine, the researchers note that the physics of a sneeze cloud are more complicated than might be expected from such a simple event.

Electrons at the speed limit
Electronic components have become faster and faster over the years, thus making powerful computers and other technologies possible. Researchers at ETH Zurich have now investigated how fast electrons can ultimately be controlled with electric fields. Their insights are of importance for the petahertz electronics of the future.

Poof! The weird case of the X-ray that came out blank
Imagine getting a medical X-ray that comes out blank – as if your bones had vanished. That’s what happened when scientists cranked up the intensity of the world’s first X-ray laser to get a better look at a sample they were studying: The X-rays seemed to go right through it as if it were not there.

Meteorite impact on a nano scale
Trenches, craters and hillocks: shapes and structures which are observed after meteorite impacts can also be found on a nanoscale, when crystals are bombarded with heavy ions. Understanding the physics of those nano-impacts helps scientists to create new nanostructures and to understand problems with electronics under extreme conditions -- for instance computer chips in space.

Crystal unclear: Why might this uncanny crystal change laser design?
New research suggests that the relatively large crystals used to change several properties of light in lasers -- changes that are crucial for making lasers into practical tools -- might be created by stacking up far smaller, rod-shaped microcrystals that can be grown easily and cheaply.
