Scientists have confirmed possible evidence of a new elementary particle, the sterile neutrino. The results from the Baksan Experiment on Sterile Transitions (BEST) found that the germanium 71 yield was 20% to 24% lower than expected based on the intensity of the neutrino source and on scientists’ knowledge of how neutrinos are absorbed. This is consistent with earlier results on the so-called gallium anomaly.

Spintronic devices are electronic devices that utilize the spin of electrons (an intrinsic form of angular momentum possessed by the electron) to achieve high-speed processing and low-cost data storage. In this regard, spin-transfer torque is a key phenomenon that enables ultrafast and low-power spintronic devices.
What are the clouds of Venus made of? Scientists know it’s mainly made of sulfuric acid droplets, with some water, chlorine, and iron.

In this study, researchers addressed the question of whether the liquids of nucleons and quarks are fundamentally different. Both liquids produce vortices when they rotate, but in quark liquids, the vortices carry a “color-magnetic field.” There is no such effect in nucleon liquids, so these vortices distinguish quark liquids from nuclear liquids.

Colliding nuclei at high speeds melts their constituent quarks and gluons into a Quark-Gluon Plasma (QGP). Quarks and gluons from the colliding nuclei also sometimes ricochet off one another very early on in the collision and form sprays of energetic particles known as jets. These jets lose their energy as they exit the plasma, with wide jets losing more energy than narrow jets. Researchers have confirmed that the plasma treats each prong of a jet independently only when the prongs are separated by a sufficiently large angle.

Fast ions that heat plasma in a fusion device can resonate with waves in the plasma, potentially causing waves to grow and kick the fast ions out of the device. This research used mathematical calculations and computer simulations to examine these resonant interactions to reveal how different types of collisions compete to determine the way energy transfers between the resonant particles and the plasma waves. The results will aid in models of how to keep plasmas hot enough to sustain fusion reactions.
