There is far more matter than antimatter in our universe, but scientists don?t know enough about the properties of antimatter to understand why. By spectroscopically analyzing atoms created when antiprotons collide with helium, physicists at CERN are measuring the properties of antimatter with unprecedented accuracy.
High-Speed Laser MS for Precise, Prep-Free Environmental Particle Tracking
April 21st 2025Scientists at Oak Ridge National Laboratory have demonstrated that a fast, laser-based mass spectrometry method—LA-ICP-TOF-MS—can accurately detect and identify airborne environmental particles, including toxic metal particles like ruthenium, without the need for complex sample preparation. The work offers a breakthrough in rapid, high-resolution analysis of environmental pollutants.
