The LHC’s computing revolution

Making new discoveries may require writing new software first. Scientists conceived of the Large Hadron Collider and its experiments in 1992. Back then, Apple was starting to figure out the laptop computer, and a CERN fellow named Tim... Continue reading

Scientists trace high-energy cosmic neutrino to its birthplace

A pair of results bring neutrinos into the new era of multi-messenger astronomy. On September 22, 2017, a tiny but energetic particle pierced Earth’s atmosphere and smashed into the planet near the Amundsen-Scott South Pole Station in... Continue reading

Out in physics

LGBT+ scientists offer advice for promoting inclusivity in a guide written for the physics and astronomy community. Traveling to an important research conference or collaboration meeting is the kind of experience that can help launch ... Continue reading

Higgs search alumni: Where are they now?

Meet four physicists who have found different ways to apply the skills they learned through their studies of the Higgs boson. The discovery of the Higgs boson, considered the missing piece of the Standard Model of particle physics, wa... Continue reading

Think big, go small

Nothing beats a small experiment for the breadth of experience it gives the scientist. In March, a team of astronomers made a shocking announcement: They appeared to have found a galaxy with a severe lack of dark matter. The finding, ... Continue reading

The LHC-watcher’s field guide

These are the event displays of Large Hadron Collider physicists’ dreams. Our current understanding of particle physics, known as the Standard Model, has been tremendously successful. Over the past 40 years, it has pointed experimenta... Continue reading

Waiting for a sign

Some scientists spend decades trying to catch a glimpse of a rare process. But with good experimental design and a lot of luck, they often need only a handful of signals to make a discovery. In 2009, University of Naples physicist Gio... Continue reading

Q&A: Planning Europe’s physics future

Halina Abramowicz leads the group effort to decide the future of European particle physics. Physics projects are getting bigger, more global, more collaborative and more advanced than ever—with long lead times for complex physics mach... Continue reading
