Four complementary analyses by Fermilab’s MicroBooNE show no signs of a theorized fourth kind of neutrino known as the sterile neutrino. Its existence is considered a possible explanation for anomalies seen in previous physics experiments.

It can help operators optimize the performance of X-ray lasers, electron microscopes, medical accelerators and other devices that depend on high-quality beams.

Scientists at the Stanford Synchrotron Radiation Lightsource will study plastics and biologically-motivated processes that break them down in hopes of finding more efficient ways to “upcycle” them.

It uses terahertz radiation to power a miniscule copper accelerator structure.
