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.
In November, the Pierre Auger Observatory outside Malargüe, Argentina, celebrates its scientific launch. The observatory will record high-energy cosmic-ray showers with ground-based water tank detectors and air-shower cameras.
Artist Robert Lang has folded intricate paper sculptures from flat sheets that, in some cases, started out over nine feet long. He uses the same method many of us used to make cranes and party hats in elementary schoola series of precise folds. But Langs designs are far more complex.
In today's particle physics experiments, it takes a fraction of a second for data recorded by detectors to be transferred to a data storage facility. Soon thereafter, collaboration members from around the world have access to the data via the Internet.
This memo by John Yoh, written on November 17, 1976, certainly caught the attention of the Columbia-Fermilab-Stony Brook collaboration (Fermilab experiment E288).
