Scientists on the Dark Energy Survey share weekly photos taken by and of the world’s most powerful digital camera. What would it be like to peer billions of years into the past, viewing hundreds of millions of galaxies, some billions of light y... Continue reading →

A new facility opens for experiments in SLAC’s historic End Station A, where the first evidence for quarks was discovered. Electrons are once again streaming into SLAC’s End Station A, setting the stage for a new facility in the huge, concret... Continue reading →

Physicists from the LHCb collaboration observe CP violation in the decay of a particle made of beauty and strange quarks. When the universe was less than a minute old, a tiny difference in the behavior of matter and antimatter led to the matter-domin... Continue reading →

The IceCube experiment makes what could be an important step toward using neutrinos to find the source of ultra-high-energy cosmic rays. Scientists on a South-Pole-based neutrino experiment reported today that they have detected the two highest-energ... Continue reading →

Like surfers on huge ocean waves, electrons can ride waves of plasma to very high energies. Plasma acceleration could be the wave of the future. It is a way to accelerate particles more efficiently than current techniques that use radiofrequency acce... Continue reading →

Symmetry sits down with Fabiola Gianotti, who recently finished an eventful four years as spokesperson for the ATLAS experiment at the Large Hadron Collider. Physicist Fabiola Gianotti, one of the two experiment leaders who announced the discovery of... Continue reading →

Judges announce the winners of the 2012 Global Particle Physics Photowalk. A stark black-and-white photo of an access tunnel 1500 meters underground and a colorful close-up of a detector that wouldn’t be out of place in a building by Catalan archit... Continue reading →

When a scientific result fails the test of “naturalness,” it can point to new physics. Suppose a team of auditors is tasked with understanding a particular billionaire’s bank account. Each month, millions of dollars flow into and out of... Continue reading →
