How the Neutrino’s Tiny Mass Could Help Solve Big Mysteries

October 15, 2019

The KATRIN experiment is closing in on the mass of the neutrino, which could point to new laws of particle physics and shape theories of cosmology.

Ann Nelson Took On the Biggest Problems in Physics

August 22, 2019

The theoretical particle physicist Ann Nelson, who died on August 4 at age 61, was a font of brilliant ideas and a champion of ending discrimination in the field.

A Call for Courage as Physicists Confront Collider Dilemma

August 7, 2019

Carlo Rubbia, leader of the bold collider experiment that in 1983 discovered the W and Z bosons, thinks particle physicists should now smash muons together in an innovative “Higgs factory.”


The Simple Idea Behind Einstein’s Greatest Discoveries

June 26, 2019

Lurking behind Einstein’s theory of gravity and our modern understanding of particle physics is the deceptively simple idea of symmetry. But physicists are beginning to question whether focusing on symmetry is still as productive as it once was.

The Physics Still Hiding in the Higgs Boson

March 4, 2019

No new particles have been found at the Large Hadron Collider since the Higgs boson in 2012, but physicists say there’s much we can still learn from the Higgs itself.

How Artificial Intelligence Can Supercharge the Search for New Particles

July 23, 2018

In the hunt for new fundamental particles, physicists have always had to make assumptions about how the particles will behave. New machine learning algorithms don’t.

The Peculiar Math That Could Underlie the Laws of Nature

July 20, 2018

New findings are fueling an old suspicion that fundamental particles and forces spring from strange eight-part numbers called “octonions.”
