April 14, 1932 was a day that transformed subatomic physics forever as a lithium atom was split using a proton beam.

The latest findings from the KATRIN experiment establish a maximum weight of under 0.45 electronvolts for neutrinos, the universe's lightest particle. Conducted over several years with international ...

Fundamental particles fall within two camps—fermions or bosons—but a new study suggests that hypothetical paraparticles could exist in a kind of inbetween. Although technically quasiparticles ...

A new measurement finds the universe's teensiest particles weigh no more than one-millionth the mass of an electron.

As if atoms weren’t already mind-blowingly small, never mind subatomic particles, CERN researchers in the CMS Collaboration ...

Physicists have shown that particles produced in collimated sprays called jets retain information about their origins in subatomic particle smashups.

A groundbreaking discovery has rocked the field of neutrino astronomy—scientists have detected an ultra-high-energy neutrino using the KM3NeT telescope, with an energy level 16,000 times greater than ...

Neutrinos, the mysterious and nearly massless particles that barely interact with anything, are revealing new secrets through the KATRIN experiment. Using tritium decay and advanced spectrometry, ...

A long-elusive, hypothetical subatomic particle called the axion can be simulated and potentially detected in a type of thin material.

Most people can't answer this science trivia ... can you? How well do you know science trivia? Even if it’s been years since ...

Physicists studied proton interactions at the Large Hadron Collider to see if they could find quantum entanglement as a ...

Apr. 15, 2025 — Extreme cosmic events such as colliding black holes or the explosions of stars can cause ripples in spacetime, so-called gravitational waves. Their discovery opened a new window ...
