A POSTECH joint research team demonstrates highly efficient 3D nano-imaging with XFEL and machine learning.

Study by researchers at the University of Campinas published in Physical Review Letters discusses both light dispersion by vibrations inside the device and light dissipation to the exterior, an aspect rarely studied hitherto.

While protons populate the nucleus of every atom in the universe, sometimes they can be squeezed into a smaller size and slip out of the nucleus for a romp on their own. Observing these squeezed protons may offer unique insights into the particles that build our universe. Now, researchers hunting for these squeezed protons have come up empty-handed, suggesting there's more to the phenomenon than first thought. The result was recently published in Physical Review Letters.

The results of a new experiment could shift research of the proton by reviving previously discarded theories of its inner workings.

Tracing back a ghostly particle to a shredded star, scientists have uncovered a gigantic cosmic particle accelerator. The subatomic particle was hurled towards Earth after the doomed star came too close to the supermassive black hole at the centre of its home galaxy and was ripped apart, as the team led by DESY scientist Robert Stein reports in the journal Nature Astronomy.

Creation of matter in an interaction of two photons belongs to a class of very rare phenomena. From the data of the ATLAS experiment at the LHC, collected with the new AFP proton detectors at the highest energies available to-date, a more accurate - and more interesting - picture of the phenomena occurring during photon collisions is emerging.
