In 2023, the ALICE experiment was ready for their best year yet, until a mysterious signal threatened everything. As the LHC wraps up its 2025 lead-ion run, physicists recall how they worked together to solve the puzzle.
An impromptu frog habitat vanished with final repairs to the roof of Fermilab's Meson Lab. Leaks—lots of leaks—have plagued the lab's 12 blue and orange concave arches since it opened 32 years ago.
What is the universe made of? What are matter, energy, space, and time? How did we get here and where are we going? In particle physics, the classic place to look for answers is in giant accelerators where particles collide. But nature also provides a wealth of data.
Search for “BaBar” on YouTube.com, and you'll get a long list of links to a 1980s TV series based on an animated elephant. But a surprise is hidden among the cartoons—a six-minute film shot in the Stanford Linear Accelerator Center's BaBar control room.
Fermi National Accelerator Laboratory in Batavia, Illinois has a challenge: how will it maintain its central role as a place where particle accelerators produce groundbreaking discoveries in physics?
Atomic element 94 was named “plutonium” after Pluto, the ninth planet from the Sun (now demoted to “minor planet” status.) By tradition, plutonium should have been assigned the symbol “Pl,” but co-discoverer Glenn Seaborg gave it the symbol “Pu” as
