Unusual Gravitational Wave Signal Generated by New Class of Binary Systems

A highly unusual gravitational wave signal, detected by the LIGO and Virgo observatories in the US and Italy, was generated by a new class of binary systems (two astronomical objects orbiting around each other), an international team of astrophysicists has confirmed.

Berkeley Lab's 88-Inch Cyclotron Used to Make New Mendelevium Isotope

A team of scientists working at Lawrence Berkeley National Laboratory has discovered a new form of the human-made element mendelevium. The newly created isotope, mendelevium-244, is the 17th and lightest form of mendelevium, which is element 101 on the periodic table.

Neutral Pions in Very Forward Collision Area Exhibit Huge Left-Right Asymmetry

A group of researchers including scientists from the RIKEN Nishina Center for Accelerator-Based Science, University of Tokyo, Nagoya University, and the Japan Atomic Energy Agency (JAEA) used the spin-polarized Relativistic Heavy Ion Collider at Brookhaven National Laboratory in the United States to show that, in polarized proton-proton collisions, neutral pions emitted in the very forward area of collisions--where direct interactions involving quarks and gluons are not applicable--still have a large degree of left-right asymmetry.
