Where did the antimatter go? Neutrinos shed promising new light

We live in a world of matter - because matter overtook antimatter, though they were both created in equal amounts by the Big Bang when our universe began.

New protocol identifies fascinating quantum states

Nowadays, modern quantum simulators offer a wide range of possibilities to prepare and investigate complex quantum states. They are realized with ultracold atoms in optical...

Looking for dark matter

Dark matter, which cannot be physically observed with ordinary instruments, is thought to account for well over half the matter in the Universe, but...

Origins of Earth’s magnetic field remain a mystery

Microscopic minerals excavated from an ancient outcrop of Jack Hills, in Western Australia, have been the subject of intense geological study, as they seem to bear traces of the Earth's magnetic field reaching as far back as 4.2 billion years ago.

A step ahead in the race toward ultrafast imaging of single particles

Using a combination of experimental and computational data, researchers discover paths to optimize pulses from highly intense X-ray beams.

Belle II yields first results in search of the Z’ boson

The Belle II experiment has been collecting data from physical measurements for about one year now.

Does relativity lie at the source of quantum exoticism?

Since its beginnings, quantum mechanics hasn't ceased to amaze us with its peculiarity, so difficult to understand.

Discovery by UMass Lowell-led team challenges nuclear theory

A discovery by a team of researchers led by UMass Lowell nuclear physicists could change how atoms are understood by scientists and help explain extreme phenomena in outer space.

High altitude water Cherenkov Observatory tests speed of light

New measurements confirm, to the highest energies yet explored, that the laws of physics hold no matter where you are or how fast you're moving.

New explanation for sudden heat collapses in plasmas can help create fusion energy

Scientists seeking to bring the fusion that powers the sun and stars to Earth must deal with sawtooth instabilities -- up-and-down swings in the central pressure and temperature of the plasma that fuels fusion reactions, similar to the serrated blades of a saw.

Argonne and CERN weigh in on the origin of heavy elements

A long-held mystery in the field of nuclear physics is why the universe is composed of the specific materials we see around us. In other words, why is it made of "this" stuff and not other stuff?

New technique looks for dark matter traces in dark places

So far, the only direct evidence we have for the existence of dark matter is through gravity-based effects on the matter we can see.
