CERN Sees High-Energy Light Interacting With Itself For The First Time

CERN Sees High-Energy Light Interacting With Itself For The First Time

A crucial prediction of the quantum theory of light has been confirmed by CERN. Physicists at the European Institution saw for the first time a high-energy photon-on-photon interaction, where two particles of light “hit” each other and change directions. The process, called light-by-light scattering, is one of the oldest predictions of quantum electrodynamics (QED), the quantum theory…

Scientists Recreate Cause Of Fusion Inside Massive Stars

Scientists Recreate Cause Of Fusion Inside Massive Stars

The energy of stars comes from nuclear fusion. At their cores, under incredible pressure and temperature, lighter elements like hydrogen and helium are fused into heavier ones. These conditions are extreme and it’s only now that researchers are getting close to replicating them. As reported in Nature Physics, American researchers have reproduced what’s happening inside…

A Neutrino Has Been Seen Hitting An Atom For The First Time

A Neutrino Has Been Seen Hitting An Atom For The First Time

The world’s smallest neutrino detector has just discovered something quite big. Researchers have observed an atom ricochet from the tiny impact of a neutrino for the first time. Such an occurrence was first predicted in theory 43 years ago, but had so far eluded scientists. The results of the experiment, conducted at the Oak Ridge National…

Paper Calls Out Pressures On Postdoctoral Researchers

Paper Calls Out Pressures On Postdoctoral Researchers

In July, a paper was published that some scientists had eagerly awaited, but not for its content. In the acknowledgments, Dr Oliver Rosten dedicated his work to a friend, Francis Dolan, who died by suicide, and called attention to the way career pressures can harm the health of postdoctoral researchers. Few outside certain fields of physics will read…
