Scientists studying particle collisions at the Relativistic Heavy Ion Collider have produced definitive evidence for two physics phenomena predicted more than 80 years ago: that matter/antimatter can be generated directly from collisions of photons and that a magnetic field can bend polarized light along different paths in a vacuum.

Every year, the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory opens its gates to thousands of community members for open house events called Summer Sundays. Visitors get to meet the Lab’s scientists and tour a different world-class science facility each week, including the Relativistic Heavy Ion Collider (RHIC), the National Synchrotron Light Source II (NSLS-II), and the Center for Functional Nanomaterials (CFN)—all DOE Office of Science User Facilities.

States of local broken symmetry at high temperature—observed in several materials, including one with a metal-insulator transition, an iron-based superconductor, and an insulating mineral part of the Earth's upper mantle—may enable the technologically relevant properties arising at much-lower temperature.

A machine learning system is helping operators resolve routine faults at the Continuous Electron Beam Accelerator Facility (CEBAF). The system monitors the accelerator cavities, where faults can trip off the CEBAF. The system identified which cavities were tripping off about 85% of the time and identified the type of fault about 78% of the time.

Scientific rules about “chiral symmetry” predict the existence of subatomic particles called pions. The lifetime of a neutrally charged pion is tied to breaking of chiral symmetry. Until recently, measurements of this lifetime have been much less precise than calculations from theory. Physicists have now measured a pion’s lifetime more precisely than ever before.

A new analysis of collisions of gold ions shows signs of a “critical point,” a change in the way one form of matter changes into another. The results hint at changes in the type of transition during the shift from particles to the quark-and-gluon “soup” that filled the early universe. This helps scientists understand how particles interact and what holds them together.

A new robotics project named Argonaut at the Department of Energy’s Fermi National Accelerator Laboratory will share that same name and spirit of adventure. Argonaut’s mission will be to monitor conditions within ultracold particle detectors by voyaging into a sea of liquid argon kept at minus-193 degrees Celsius — as cold as some of the moons of Saturn and Jupiter.

呼吸气溶胶是呼吸气体的常见组成部分，也是COVID-19等呼吸道病毒传播给他人和各种表面的常见途径。在妙佑医疗国际(Mayo Clinic) 对心脏病患者进行运动负荷试验的研究人员发现，随着运动强度的增加，房间周围气溶胶的浓度也会增加。他们还发现，高效微粒空气过滤器(HEPA)可有效地过滤气溶胶，减少患者之间更换清新空气所需的时间。
