Quantum vortex formation in the lab

Quantized vortices can be generated in classical experiments of liquid helium and ultracold dilute gases to conduct fundamental and comparative studies of different superfluids. In a new report published in Science Advances, ...

'Doomsday Clock' moves closest ever to midnight

Top scientists and security experts moved the "Doomsday Clock" forward on Tuesday to just 90 seconds to midnight -– signaling an increased risk to humanity's survival from the nuclear shadow over the Ukraine conflict and ...

Ripples in fabric of universe may reveal start of time

Scientists have advanced in discovering how to use ripples in space-time known as gravitational waves to peer back to the beginning of everything we know. The researchers say they can better understand the state of the cosmos ...

Doomsday Clock to be updated on January 24

Tick, tick, tick. An update is coming to the "Doomsday Clock," representing the judgment of leading science and security experts about the perils to human existence.

Physicists observe wormhole dynamics using a quantum computer

Scientists have, for the first time, developed a quantum experiment that allows them to study the dynamics, or behavior, of a special kind of theoretical wormhole. The experiment has not created an actual wormhole (a rupture ...

Spin correlation between paired electrons demonstrated

Physicists at the University of Basel have experimentally demonstrated for the first time that there is a negative correlation between the two spins of an entangled pair of electrons from a superconductor. For their study, ...
