Poder frenar una parte de la molécula con un simple haz de luz abre la puerta a dispositivos que algún día cumplan funciones precisas dentro del cuerpo o en materiales nuevos. Cuando la luz empieza a mandar sobre lo que se mueve de manera aleatoria, lo que hoy es ruido de fondo puede volverse la herramienta que mañana use cualquier laboratorio.","quienFirma":"IOCB Prague","confianza":"revisado","consulta":null},"sello":{"hash":"b2ca02538c50021dd6502747d512cfe5ee1f509645d571122c45987d087a2170","sello":"4f0afb1d3d50b6beffbef30cb31616f689e403c511c29a766d308f292190f071","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6590171,"aleatorio":"eef66e38f09b32ac407e78ee90db3578ac0bd46b5496246439dc28dbd8d5546e","tiempo":"2026-10-27T21:22:30.000Z"},"nist":{"cadena":2,"pulso":2002019,"salida":"3917A1F71CAC018864368028ED97098C5C523094827DAC96A05B4ADD47CF6A718068DB0AA0379C285CFE7E3A847027ED0355A98415B9B196730DF1CC27EF7A94","tiempo":"2026-10-27T21:21:00.000Z"},"noAntes":"2026-10-27T21:22:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 27 21:22:40 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Light-controlled brake makes random molecular motion 300,000 times slower","descripcion":"Molecules are never still. Driven by thermal energy, they are constantly moving through space, while their individual parts also rotate relative to one another. Scientists at IOCB Prague have now shown that random motion within a molecule can be dramatically suppressed. Using light, they can slow down the relative rotation of two different parts of a single molecule by up to five orders of magnitude, paving the way for more complex molecular machines.","pubDate":"Tue, 27 Oct 2026 17:20:06 EDT","url":"https://phys.org/news/2026-10-random-molecular-motion-slower.html"},"indexado":"2026-10-27T21:22:23.054Z"}}
