The radius of the particles in the outflow from 3I/ATLAS must be bigger than 1 micron in order for them to reach the observed ...

Household gadgets have a way of sounding scarier than they are once someone attaches a giant number to them. The claim that a ...

At every moment, subatomic particles stream in unfathomable numbers through your body. Each second, about 100 billion neutrinos from the sun pass through your thumbnail, and you’re bathed in a rain of ...

Physicists have found evidence of X particles in the quark-gluon plasma produced in the Large Hadron Collider (LHC) at CERN, the European Organization for Nuclear Research, based near Geneva, ...

Small particles from tires inhibited the growth and caused adverse behavioral changes in organisms found in freshwater and coastal estuary ecosystems, two new research papers found. Small particles ...

Physicists at the world's largest atom smasher have detected a mysterious, primordial particle from the dawn of time. About 100 of the short-lived "X" particles — so named because of their unknown ...

Tiny particles of plastic have been found everywhere — from the deepest place on the planet, the Mariana Trench, to the top of Mount Everest. And now more and more studies are finding that ...

Massive gravitons may have formed a trillionth of a second after the Big Bang, in abundances great enough to account for dark matter. When you purchase through links on our site, we may earn an ...

This week in science: the choice between tea or coffee could have greater consequences than you think; interstellar comet ...

Breaking the rules is exciting, especially if they have held for a long time. This is true not just in life but also in particle physics. Here the rule I'm thinking of is called “lepton flavor ...
