Poder ver cada impacto por separado abre la puerta a instrumentos de medición mucho más precisos. Para un país que quiere desarrollar ciencia y tecnología de punta, este tipo de avance es una base para investigar física nueva sin depender de grandes presupuestos. Lo que hoy parece un experimento minúsculo puede terminar definiendo cómo se mide el mundo a escala muy pequeña.","quienFirma":"Physical Review Letters (publicación revisada por pares)","confianza":"revisado","consulta":null},"sello":{"hash":"62cc73bb6e106f3fe6d26a7d73813db0c8cf5377949b8952b51c234c67120e7e","sello":"ba1ca7b9fd94ec7a83861e96aab979d504936d85bad4f33525784bb92ecb8926","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6569512,"aleatorio":"68d891400eb4a7a9a853dde0ba6f2a3e82e776d6bc6930813627093e18bfff2a","tiempo":"2026-10-20T17:13:00.000Z"},"nist":{"cadena":2,"pulso":1991961,"salida":"884D7D008E30E195FCBB1957B251EC955463ED1EE1547E3FAD244096CB280EAE20C67DE0FA1957D7079A169BC92DA7370ED494880887D97524E263406434BA5F","tiempo":"2026-10-20T17:12:00.000Z"},"noAntes":"2026-10-20T17:13:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 20 17:13:07 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Individual atomic collisions can now be detected in the lab, potentially opening up pathways to new physics","descripcion":"Tiny atoms and molecules are constantly bombarding each other all around us. While we regularly measure the large-scale effects of these interactions, measuring the effect of each individual collision is far more difficult. But now, researchers have managed to measure how tiny gas particles affect a single silica particle in the lab. In their new study, published in Physical Review Letters, the team describes how they detected the momentum transfers of individual collisions of gas particles with a nanoparticle levitated in laser light.","pubDate":"Tue, 20 Oct 2026 13:10:01 EDT","url":"https://phys.org/news/2026-10-individual-atomic-collisions-lab-potentially.html"},"indexado":"2026-10-20T17:12:51.642Z"}}
