Collisions of Light Produce Matter/Antimatter from Pure Energy
Brookhaven National Laboratory

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.

Virtual Summer Sundays Return
Brookhaven National Laboratory

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.

Uncovering Hidden Local States in a Quantum Material
Brookhaven National Laboratory

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.

Machine Learning System Improves Accelerator Diagnostics
Department of Energy, Office of Science

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.

Precise Measurement of Pions Confirms Understanding of Fundamental Symmetry
Department of Energy, Office of Science

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.

Signs of “Turbulence” in Collisions that Melt Gold Ions
Department of Energy, Office of Science

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.

مدينة روتشستر، ولاية مينيسوتا — رذاذ الأيروسول التنفسي مكون شائع للنفس، وطريقة شائعة لنشر فيروسات الجهاز التنفسي مثل فيروس كورونا المستجد (كوفيد-19) إلى الأشخاص والأسطح الأخرى. وجد الباحثون الذين أجروا اختبارات الإجهاد المتعلقة بالتمارين لمرضى القلب في مايو كلينك أن ممارسة الرياضة بمستويات متزايدة من المجهود تزيد من تركيز الأيروسول في الغرفة المحيطة. ووجدوا أيضًا أن منقيات جزيئات الهواء عالية الكفاءة (HEPA) ترشح رذاذ الأيروسول بشكل فعال وتقلل الوقت اللازم لتنقية الهواء بين المرضى.
