Using sheets of light to corral waves of ultracold atoms, researchers have created an experimental platform for studying the event horizons of black holes. Making waves. Researchers have created a ...

Researchers have used radio observations of rapidly spinning neutron stars to search for signals from supermassive black hole pairs at the dawn of galaxy formation. In our lifetimes, an amazing thing ...

A decades-old neutrino mystery might be solved not by undiscovered physics but by improved calculations. For more than 30 years, scientists have found that roughly 20% fewer electron neutrinos are ...

A hallmark property of unconventional superconductivity has been discovered in a type-I superconductor, whereas it’s normally observed only in type-II materials. Superconductors can be broadly ...

A proposed lab-based quantum sensor could precisely measure within seconds the warping of spacetime caused by Earth’s rotation. Einstein’s theory of general relativity predicts that Earth’s rotation ...

Junsuk Rho received his PhD in mechanical engineering and nanoscale science and engineering from the University of California, Berkeley. He is currently a chair professor in the Departments of ...

Different analyses of gravitational-wave observations are converging on evidence for a distinct population of massive black hole binaries produced through repeated mergers. Figure 1: Hundreds of ...

Through a quantum-switch experiment, researchers attempt to reveal “indefinite causal order”—a quantum phenomenon involving events in a before-and-after superposition. Artistic rendition of the ...

Using a rapid pressure-quench technique, researchers have preserved a metastable phase in a superconductor at a record 151 K under ambient pressure. The pressure-quench protocol starts by placing a ...

The new map of the Universe’s expansion history released by the DESI Collaboration offers hints at a breakdown of the standard model of cosmology. Figure 1: A slice of DESI’s first three years of data ...

Two direct-detection experiments see no evidence of a signal reported by their predecessor. In 1997, the DAMA/NaI experiment observed a signal whose annual variability was suggestive of dark matter.

A Bose-Einstein condensate of radioactive atoms could turn into a source of intense, coherent, and directional neutrino beams, according to a theoretical proposal. Figure 1: Top: At high temperature, ...
