A supersensitive dark matter search found no signs of the substance — yet

The next generation of dark matter detectors has arrived. A massive new effort to detect the elusive substance has reported its first results. Following a time-honored tradition of dark matter…

How physicists are probing the Higgs boson 10 years after its discovery

Javier Duarte kicked off his scientific career by witnessing the biggest particle physics event in decades. On July 4, 2012, scientists at the laboratory CERN near Geneva announced the discovery…

How neutrinos could ensure a submarine’s nuclear fuel isn’t weaponized

Nuclear submarines might provide rogue nations with a path to nuclear weapons. But neutrinos could help reveal attempts to go from boats to bombs. Neutrinos, lightweight subatomic particles that are…

High-energy neutrinos may come from black holes ripping apart stars

When a star gets too close to a black hole, sparks fly. And, potentially, so do subatomic particles called neutrinos. A dramatic light show results when a supermassive black hole…

The Large Hadron Collider has restarted with upgraded proton-smashing potential

After a hiatus of more than three years, the Large Hadron Collider is back. Scientists shut down the particle accelerator in 2018 to allow for upgrades (SN: 12/3/18). On April…

Muons spill secrets about Earth’s hidden structures

Inside Egypt’s Great Pyramid of Giza lies a mysterious cavity, its void unseen by any living human, its surface untouched by modern hands. But luckily, scientists are no longer limited…

A new nuclear imaging prototype detects tumors’ faint glow

A type of light commonly observed in astrophysics experiments and nuclear reactors can help detect cancer. In a clinical trial, a prototype of an imaging machine that relies on this…

The W boson might be extra hefty. If so, it could hint at new physics

There’s something amiss with a mass. A new measurement of the mass of an elementary particle, the W boson, has defied expectations. The result hints at a possible flaw in…

How light from black holes is narrowing the search for axions

The search for a hypothetical subatomic particle that could signal new physics just narrowed a bit — thanks to the light swirling around a gargantuan black hole in another galaxy.…

A new particle accelerator aims to unlock secrets of bizarre atomic nuclei

Inscribed on an Italian family’s 15th century coat of arms and decorating an ancient Japanese shrine, the Borromean rings are symbolically potent. Remove one ring from the trio of linked…
