Cuando el daño no se arregla, se acumulan errores que pueden abrir la puerta a distintas enfermedades. Entender cómo funciona esa reparación es clave para pensar cómo se previenen esos problemas. Lo que no se sabe todavía es cuánto de ese mecanismo puede ajustarse sin efectos secundarios.","quienFirma":"Phys.org (divulgación; origen científico no especificado en la fuente)","confianza":"divulgacion","consulta":null},"sello":{"hash":"f168ee129afc9faf2f81cfb71b1dcdaea741209c913b2da8e02b74ee4bc354f3","sello":"a9383c592ece47a25b018c936477ab53e303bbcc8bda6a500639a3540e325235","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6569731,"aleatorio":"af9bf7dd10d9c4a3d772ae4e96da935d89fac6f25eb92414cf1882e72921c4a4","tiempo":"2026-10-20T19:02:30.000Z"},"nist":{"cadena":2,"pulso":1992071,"salida":"BF0AA6B0DC9249EC7460458477B9443D7D6A986D206A14015A492FA0B1CA2F43352675BFB7BFAEBEAAB2655071B90C012314019B3CF752BF0BBE25B4CC258D62","tiempo":"2026-10-20T19:02:00.000Z"},"noAntes":"2026-10-20T19:02:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 20 19:02:54 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Unraveling DNA repair: How cells protect their genetic blueprint","descripcion":"Every cell in the human body faces a chronic challenge: protecting its DNA.
