In late October SuperCDMS scientists cooled their dilution refrigerator down to 5.3 millikelvin, only a few thousandths of a kelvin above absolute zero.
Astrophysicist Risa Wechsler explores why dark matter may be the key to understanding how the universe formed, and shares how physicists in labs around the world are coming up with creative ways to study it.
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.
Long after the hard shaking stops, an earthquake's seismic waves reverberate around the world, imperceptibly rocking the ground. As one seismologist puts it, a great earthquake causes every grain of sand on Earth to dance.
Since its launch in June 2008, the Fermi Gamma-ray Space Telescope has shed light on some of the brightest, most explosive events in the universe and opened tantalizing windows into dark matter and the nature of space-time.
A long time ago in a national laboratory far, far away some physicists looked around their workplace and thought of dark forces. Not dark matter; not dark energy; but the ultimate force from the dark side: Darth Vader.
When the Bevatron switched on at Lawrence Berkeley National Laboratory in the fall of 1954, it was the largest particle accelerator ever built, capable of producing energies upwards of six billion electronvolts.
In August, robots, mummies, and giant jellyfish took over Chicago's Millennium Park. Fortunately, the invasion was peaceful—just part of the fun at the latest LabFest, a kind of pumped-up, hands-on outdoor science fair aimed to engage Chicagoans in the excitement of science.
She could take her pick of extreme adventures—rock climbing, skydiving, trekking through some exotic wilderness. The Swiss TV show Sportpanorama gave Dominique Gisin, winner of two International Ski Federation World Cup downhill victories in 2009, the chance to do anything she'd like.
