Scientists have observed a unique particle that moves easily one way, yet resists at 90 degrees. These semi-Dirac fermions were observed using their energy signature in a topological metal ...

For the first time, scientists have observed a collection of particles, also known as a quasiparticle, that's massless when moving one direction but has mass in the other direction. The ...

Particle motion could be assessed from the directional sensory hair cells, and sound pressure from the vibration of an air-bubble structure, such as the swim bladder of a fish.

Mathematicians at the Universities of York, Munich and Cardiff have identified a unique property of quantum mechanical particles – they can move in the opposite way to the direction in which they are ...
