Scientists trapped antimatter particle for months — but studying it without blowing up lab was a challenge
NY Post | 10/25/2026 | Brandon CruzA team of physicists recently trapped a single antimatter particle for months — a delicate feat where one wrong move could’ve blown up their lab, according to new research.
Antimatter, which explodes when it comes into contact with the ordinary matter, was captured by researchers at Northwestern University and stored in a cold box where they used incredibly cold temps and magnets to suspend the particle in midair, according to findings published in the Physical Review Letters…
To keep it from touching anything, the team built a contraption called a “one-positron quantum cyclotron,” which uses near zero temperatures and invisible magnetic and electric forces to keep the particle floating in a vacuum, keeping it from ever touching a single wall.
The first-of-its-kind experiment put the particle into its lowest possible energy state, letting scientists control it with pinpoint precision for months without destroying it in order to study whether antimatter behaves differently than regular matter it mirrors.
The fearless physicists at Northwestern University, under the guidance of Gerald Gabrielse, first snagged the particle as it shot out of radioactive material, then froze it to just 0.3 degrees above absolute zero — negative 459.67 degrees Fahrenheit.
All I want for Christmas is a One-Positron Quantum Cyclotron.
I could drop it in my car’s engine and see what happens.

Y’know, in this context, “pinpoint precision” isn’t all that great.
“My God, where are they keeping this dangerous thing?”
“Experts have stored it in a cold box.”
“What? What sort of cold box?”
“A cold.
Box.”
Megatron:
“I once transformed into a Positron but didn’t like it because it was too confining….and no Positron chicks anywhere.”
Scientists plan to invite the protesters to a release party, closely-observed from a discreet distance, just in case…
This sounds like somebody watched Project Hail Mary and changed the particle name to anti-matter.
Not your ordinary magnetic and electric forces, mind you. They used invisible magnetic and electric forces!
Diabolical!
