When researchers reanalyzed the gold-standard data set of the early universe, they concluded that the cosmos must be “closed,” or curled up like a ball. Most others remain unconvinced.
Light dark photons? Dark Higgs bosons? Scientists look for signs of these weird-sounding particles in data from BaBar—an experiment designed to explain a completely different mystery.
Almost a mile underground, in a new science facility in South Dakota, scientists of the LUX collaboration are building the world's largest dark-matter search experiment.
Physicists have used advances in accelerator technology to develop a revolutionary machine-the Linac Coherent Light Source-for exploring the world on the smallest and fastest scales. Physicist Herman Winick describes the start of the LCLS and the spectacular results that are now rolling in.
Thin layers of diamonds have become useful tools inside the detectors at the Large Hadron Collider. They're robust enough to monitor the harsh conditions, and they can even provide incredibly precise measurements of the timing of passing particles.
This year, results from the Large Hadron Collider in Europe and the Tevatron in the United States will either prove or refute the existence of the Standard Model Higgs particle, a keystone in theorists’ proposed explanation for the origin of mass.
In 1991, physicists, computer scientists, and a librarian at what is now SLAC National Accelerator Laboratory opened the first website in North America.
