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.
‘Tis the season for science at the bottom of the Earth. Researchers are flying to the South Pole from all over the globe to take advantage of the “ warm” summer months, when temperatures average minus 35 degrees Fahrenheit.
In the fall of 1997, I was leading the calibration and analysis of data gathered by the High-z Supernova Search Team, one of two teams of scientists the other was the Supernova Cosmology Projecttrying to determine the fate of our universe: Will it expand forever, or will it halt and contract, r
Monica Dunford couldn’t stop swaying when she finally got out of the boat after 15 hours, 33 minutes, and 15 seconds of hard rowing. The physicist and her four teammates had just won the Tour du Leman, held Sept. 22.
The next big experiment in particle physics won’t need an accelerator, detector, or other big machine. It doesn’t even involve subatomic particles—unless you count the electrons that flow through electronic circuits, carrying bits of information from one human brain to the next.
