How mortal filaments' self-assemble and maintain order: Align or die      (via sciencedaily.com)     Original source 

A previously unknown mechanism of active matter self-organization essential for bacterial cell division follows the motto 'dying to align': Misaligned filaments 'die' spontaneously to form a ring structure at the center of the dividing cell. The work could find applications in developing synthetic self-healing materials.

First measurement of electron- and muon-neutrino interaction rates at the highest energy ever detected from an artificial source      (via sciencedaily.com)     Original source 

Understanding neutrino interactions is crucial for obtaining a complete picture of particle physics and the universe. To date, neutrino interaction cross sections have not been measured at high energy above some hundred gigaelectronvolts at particle colliders. Now, researchers have obtained the first direct observation of electron and muon neutrino interactions in the Teraelectronvolt range at CERN's Large Hadron Collider, using the FASER detector. This study marks a significant step for particle physics research.

Cold antimatter for quantum state-resolved precision measurements      (via sciencedaily.com)     Original source 

Why does the universe contain matter and (virtually) no antimatter? Scientists have achieved an experimental breakthrough in this context. It can contribute to measuring the mass and magnetic moment of antiprotons more precisely than ever before -- and thus identify possible matter-antimatter asymmetries. They have developed a trap, which can cool individual antiprotons much more rapidly than in the past.
