Plus invisible tattoos, medieval skeleton gets an ID, trapping a single antimatter particle, and more.

According to quantum electrodynamics, the theory describing interactions between light and electrically charged particles, a sufficiently strong electric field can, in principle, convert some of its energy into particles and their antimatter partners.…

These elusive and reactive particles have been challenging to hold on to and even more challenging to study, but a new method paves the way for tests on the differences between matter and antimatter.

The positron is the antimatter counterpart of the electron, identical in mass but carrying an equal and opposite electric charge. Like the electron, it also behaves like a tiny bar magnet, and according to a key prediction of the Standard Model of…

The standard model of particle physics works really well, but it can't explain why the universe exists. Something is missing, and this trapped particle might hold a clue to the answer

Physicists at Northwestern University have successfully trapped a single positron for an entire month, allowing researchers to study its quantum properties with unprecedented precision.…

Nature staff discuss how precisely measuring a positron could shed light on one of physics’ greatest mysteries — plus, the latest on an ambitious mission to a Martian moon. Hear the biggest stories from the world of science | 23 October 2026

In the early Universe, neutrinos interacted strongly with other matter before some of them "decoupled." The heaviest of these decoupled neutrinos may be the solution to the matter-antimatter cosmic mystery.

Physicists trap and cool down positron for months to measure its ‘magnetic moment’ with extraordinary precision.

Here in our Universe, one great mystery is how, if matter and antimatter can only be created or destroyed in equal-and-opposite amounts, our Universe came to be dominated by normal (regular) matter, with barely a trace of antimatter present.…

Our dream of journeying to other star systems has a big obstacle to overcome: the vast interstellar distances. Can antimatter get us there?

Scientists successfully transported 92 antiprotons in a truck around CERN, Europe’s particle physics laboratory, using specialized bottles which prevent contact with matter.

An international team combining two major neutrino experiments has uncovered stronger evidence that neutrinos and antimatter don’t behave as perfect mirror images.…
