Wiggling metal beams offer a new way to test gravity’s strength
A new experiment aims to get a better handle on “Big G,” the poorly measured gravitational constant.

A supersensitive dark matter search found no signs of the substance — yet
The LZ experiment’s first measurement raises hopes that scientists are closer than ever to finding the source of much of the universe’s mass.

Aliens could send quantum messages to Earth, calculations suggest
Scientists are developing quantum communications networks on Earth. Aliens, if they exist, could be going further.

How physicists are probing the Higgs boson 10 years after its discovery
The famous particle may point to cracks in the standard model and new physics beyond.

Physicists may have finally spotted elusive clusters of four neutrons
Long-sought clumps of four neutrons called tetraneutrons last less than a billionth of a trillionth of a second, an experiment suggests.

Gravitational wave ‘radar’ could help map the invisible universe
Gravity ripples scattering off warped spacetime near massive objects might help astronomers peer inside stars and find globs of dark matter.

How fast a row of dominoes topples depends on friction
Computer simulations reveal that two types of friction are important in determining how quickly dominoes collapse.

Why even small sonic booms are more annoying in cities
Quieter sonic booms from next-generation planes could still be annoying in cities thanks to narrow streets and tall buildings, simulations suggest.

Scientists created ‘smoke rings’ of light
A swirling doughnut of light shows that vortex rings aren’t just for fluids anymore.

Quantum physics exponentially improves some types of machine learning
It wasn’t entirely clear if quantum computers could improve machine learning in practice, but new experiments and theoretical proofs show that it can.
