The top 40 physics hits of 2012

The Higgs boson is a popular subject among the most-cited physics papers of 2012, but a particle simulation manual takes the top spot. Think of it as a particle physics version of pop radio's “top 40” countdown: INSPIRE, a database of particle-ph... Continue reading

Symmetry challenge: Neutrino oscillation analogy

Symmetry is on the hunt for the best analogy to describe neutrino oscillation, the process by which a neutrino changes from one flavor to the next. This summer the most powerful neutrino detector in the United States, the NOvA detector, will start ca... Continue reading

The Fellowship of the Ring

The Muon g-2 experiment kicks off this summer with the move of a 50-foot-wide ring-shaped cryostat from New York to Illinois. It’s not often that big science comes rolling right through your town. For those who live between Brookhaven National Labo... Continue reading

A knack for exploring

With a solid grounding in physics, Thomas Humphrey shares the fun of discovery at San Francisco’s Exploratorium. In 1973, graduate student Thomas Humphrey considered becoming an accelerator physicist because he liked working with small groups a... Continue reading

Smallest lab-made drop of liquid might cause strange particle behavior

A new result from the CMS collaboration takes a step toward revealing the origin of the mysterious ‘ridge effect.’ The Large Hadron Collider is known for a list of impressive facts—it’s the world’s largest and most powerful particle... Continue reading

Dark-matter detector hears first particle pops

The COUPP-60 dark-matter experiment begins recording the trails of bubbles that passing particles form in its detector. Pop pop pop! The sound of bubbles bursting Wednesday morning signaled that a new dark-matter detector is up and running. The COUPP... Continue reading

Free from the start

Since CERN released the World Wide Web without royalties 20 years ago, the technology has flourished. Twenty years ago today, the web was set free. In a statement published by the particle physics laboratory CERN on April 30, 1993, World Wide Web tec... Continue reading

Matter, antimatter, we all fall down—right?

Scientists perform the first direct investigation into how antimatter interacts with gravity. What goes up must come down, the saying goes. But things might work a little differently with antimatter. A CERN-based experiment has taken the first step i... Continue reading
