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. Particles ...

An illustration of the calculated structure of ZrSiS near the crossing points of its structure, showing a semi-Dirac point as a black sphere on the left. Data points as purple dots support the ...

For the first time, scientists have caught a glimpse of a strange and elusive creature in the world of quantum physics—a semi-Dirac fermion. This unusual quasiparticle behaves as if it has no mass in ...

Scientists have accidentally discovered a particle that has mass when traveling in one direction, but no mass while moving in a different direction. Known as semi-Dirac fermions, particles with this ...

Scientists from Delft, Vienna, and Lausanne discovered that the protein machines that shape our DNA can switch direction.

We live under the assumption that time flows in one direction—past to present to future. You wake up, drink your coffee, scroll on your phone, and move forward through the day. But what if time ...

What if time is not as fixed as we thought? Imagine that instead of flowing in one direction—from past to future—time could flow forward or backwards due to processes taking place at the quantum level ...

UNIVERSITY PARK, Pa. — 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 ...

What if the flow of time isn’t as one-way as it seems? Researchers from the University of Surrey have uncovered evidence that in the strange world of quantum physics, time could theoretically run both ...
