This is an important step to unlock more applications for terahertz waves.

Researchers demonstrate how magnetism can be actively changed by pressure

Magnetism occurs depending on how electrons behave. For example, the elementary particles can generate an electric current with their charge and thereby induce a magnetic field. However, magnetism can also arise through the collective alignment of the magnetic moments (spins) in a material. What has not been possible until now, however, is to continuously change the type of magnetism in a crystal.

How do quark-gluon-plasma fireballs explode into hadrons?

Quark gluon plasma (QGP) is an exciting state of matter that scientists create in a laboratory by colliding two heavy nuclei. These collisions produce a QGP fireball. The fireball expands and cools following the laws of hydrodynamics, which govern how fluids behave in various conditions. Eventually, subatomic particles (protons, pions, and other hadrons, or particles made up of two or more quarks) emerge and are observed and counted by detectors surrounding the collision.

Why string theory requires extra dimensions

String theory found its origins in an attempt to understand the nascent experiments revealing the strong nuclear force. Eventually another theory, one based on particles called quarks and force carriers called gluons, would supplant it, but in the deep mathematical bones of the young string theory physicists would find curious structures, half-glimpsed ghosts, that would point to something more. Something deeper.

Anthropologist offers blueprint for new ways of being and relating to others in wake of disaster

Aidan Seale-Feldman knows a thing or two about what it's like to witness a disaster. She was working in Nepal in 2015 when a 7.8-magnitude earthquake struck the central region of the country, followed by a 7.3-magnitude aftershock, both of which claimed the lives of more than 9,000 people in total once the ground had ceased heaving and the dust had finally settled.
