Advanced atom interferometer could help with 'the embarrassing problem' of dark matter
Assuming dark matter exists, its interactions with ordinary matter are so subtle that even the most sensitive instruments cannot detect them. In a new study, Northwestern University physicists now introduce a highly sensitive ...

Eyes on the sun: Naked thallium-205 ion decay reveals history over millions of years
The sun, the essential engine that sustains life on Earth, generates its tremendous energy through the process of nuclear fusion. At the same time, it releases a continuous stream of neutrinos—particles that serve as messengers ...

AI algorithm intensifies gold ion collisions at near-light speed
At Brookhaven National Laboratory's (BNL's) Relativistic Heavy Ion Collider (RHIC), billions of gold ions race through magnets at nearly the speed of light. Thousands of times per second, they collide head-on, breaking into ...

The first search for soft unclustered energy patterns in proton–proton collisions at 13TeV
A key objective of many physics studies is to experimentally observe exotic phenomena beyond the Standard Model (SM) that are predicted by theoretical models. These include hidden valley models, which predict the existence ...
Particle that only has mass when moving in one direction observed for first time
For the first time, scientists have observed a collection of particles, also known as a quasiparticle, that's massless when moving one direction but has mass in the other direction. The quasiparticle, called a semi-Dirac ...

Alena Tensor—a new hope for unification in physics
The search for quantum gravity has gone on for 100 years, but it is not the only unification challenge in physics. Many of us believe that one day there will be a unification theory—a theory that will reconcile many divergent ...
Behind the model: Visualizing an advanced spectrometer with 3D printing
The Department of Energy's Thomas Jefferson National Accelerator Facility scientists have brought the Solenoidal Large Intensity Device (SoLID) experiment to life with a detailed 3D-printed model, small enough to sit on a ...

Judging knot strength throws people for a loop: Experiment reveals new blind spot in our physical reasoning
We tie our shoes, we put on neckties, we wrestle with power cords. Yet despite deep familiarity with knots, most people cannot tell a weak knot from a strong one by looking at them, new Johns Hopkins University research finds.

How can physics models prevent deadly stampedes at mass gatherings?
The death of at least 56 people in a stampede at a soccer stadium in Nzérékoré, Guinea, is the latest example of how quickly mass gatherings can turn catastrophic.

ALICE finds first ever evidence of the antimatter partner of hyperhelium-4
Collisions between heavy ions at the Large Hadron Collider (LHC) create quark–gluon plasma, a hot and dense state of matter that is thought to have filled the universe around one millionth of a second after the Big Bang. ...

Getting a grip on quark mixing: Physicists introduce framework to determine amount of mixing between up and down quarks
The quarks that make up the nuclei of all atoms around us are known to "mix": the different types of quark occasionally change into one another. The amounts in which these processes happen are not very well known, though—and ...
