A new study suggests that many theorized heavy particles, if they exist at all, do not have the properties needed to explain the predominance of matter over antimatter in the universe. If confirmed, ...

Aristos is a Newsweek science and health reporter with the London, U.K., bureau. He is particularly focused on archaeology and paleontology, although he has covered a wide variety of topics ranging ...

The Standard Model is the modern physical understanding of three of the four forces of nature: electromagnetism, the strong nuclear force and the weak nuclear force. When you purchase through links on ...

Electrons are extremely round, and some physicists are not pleased about it. A new experiment captured the most detailed view of electrons to date, using lasers to reveal evidence of particles ...

Physicists have placed a new limit on how big the elusive neutrino can be—one of the universe’s smallest known particles—a limit that makes other subatomic particles look as big as black holes by ...

A team of researchers at the University of Chicago recently embarked on the search of a lifetime—or rather, a search for the lifetime of long-lived supersymmetric particles. Supersymmetry is a ...

China is nearing completion of an advanced facility to measure neutrinos, the smallest subatomic particles known to physicists. Its underground central sphere will soon be sealed off and filled with ...

Quantum physicists regularly ask you with a straight face to accept what seems to be complete nonsense. Particles are also waves; cats are alive and dead at the same time. But some of the most ...

An invisible drizzle of subatomic particles has shown that thunderstorms may store up much higher electric voltages than we thought. Using muons, heavier relatives of electrons that constantly rain ...
