As muons race around a ring at the Fermi National Accelerator Laboratory, their spin axes twirl, reflecting the influence of unseen particles. FERMI NATIONAL ACCELERATOR LABORATORY In 1986, the TV journalist Dan Rather was attacked in New York City. A deranged assailant pummeled him while cryptically demanding, “Kenneth, what’s the […]

Physicists from MIPT and Vladimir State University, Russia, have achieved a nearly 90% efficiency converting light energy into surface waves on graphene. They relied on a laser-like energy conversion scheme and collective resonances. The […]

An MIT-led search for axions from nearby star Betelgeuse (pictured here) came up empty, significantly narrowing the search for hypothetical dark matter particle. Credit: Collage by MIT News.

Electron beamlets as observed on YAG screens at varying distances from a cathode source. Credit: Argonne National Laboratory Beam-driven wakefield acceleration approaches are promising candidates for future large-scale machines, including X-ray free electron lasers and linear colliders, as they have the potential to improve efficiency and reduce operation cost. One […]

An artistic rendering of the XMM-Newton (X-ray multi-mirror mission) space telescope. A study of archival data from the XMM-Newton and the Chandra X-ray space telescopes found evidence of high levels of X-ray emission from the nearby Magnificent Seven neutron stars, which may arise from the hypothetical particles known as axions. […]

At the University of Notre Dame, part of the Oak Ridge Deuterated Spectroscopic Array measured a reaction that causes noise in some neutrino detectors. Credit: Michael Febbraro/ORNL, U.S. Dept. of Energy Led by the Department of Energy’s Oak Ridge National Laboratory, a new study clears up a discrepancy regarding the […]

ANIMATION Scientific articles in the field of physics are mostly very short and deal with a very restricted topic. A remarkable exception to this is an article published recently by physicists from the Universities of Münster and Düsseldorf. The article is 127 pages long, cites a total of 1075 sources […]

Starting from individual ultracold atoms, Heidelberg University […]

In the 1970s, physicists uncovered a problem with the Standard Model of particle physics—the theory that describes three of the four fundamental forces of nature (electromagnetic, weak, and strong interactions; the fourth is gravity). They found that, while the theory predicts that a symmetry between particles and forces in our Universe […]
