Según el modelo, aun eliminando todas las otras causas de envejecimiento, la mediana de vida no superaría ese techo. Para alguien de acá, esto implica que las promesas de vivir indefinidamente tienen un límite biológico que no se resuelve solo con tratamientos. Es una tesis teórica que todavía necesita verificación experimental.","quienFirma":"Zenodo (autor independiente, sin institución identificada)","confianza":"preprint","consulta":{"pregunta":"¿Cree que la vida humana tiene un límite biológico?"}},"sello":{"hash":"f75b74394e22b1b010459e238ba935002de8690201c51bcc7fe01fbfcc9b0386","sello":"ccc8553ea0f46fc8511abc39fce8c7149e0b1d3cc7f3aeb4c28fc2d3e15d7ba4","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6586006,"aleatorio":"d6794bde4beba90fbb2659275104bace2e5be552d7e13226fc4be5aa3a3d7af2","tiempo":"2026-10-26T10:40:00.000Z"},"nist":{"cadena":2,"pulso":2000196,"salida":"682C2071591416231363C17F39DBA70DD3927D0BCB0F90D10E6F95BBC01165AE84133522826B4A92F30EC6EC7FC63B7129C27E864E001AA6F6A01C24042BB9D2","tiempo":"2026-10-26T10:39:00.000Z"},"noAntes":"2026-10-26T10:40:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 26 10:40:28 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"体细胞突变:人类寿命150岁是渐近线而非目标(熵天花板)(编号104-A)","descripcion":"Rejuvenation biology now reverses several ageing phenotypes in mammals: senolytics, partial reprogramming and cardiac gene therapy restore function once thought permanently lost. These advances invite the inference that aging is an engineering problem with no fixed upper bound. I argue this inference is structurally incomplete. Somatic mutations are irreversible information loss, and a quantitative model suggests that eliminating every other hallmark would still cap median human lifespan near 150 years. I develop the molecular mechanism: base-excision and nucleotide-excision repair use the complementary strand as template; mismatch repair is replication-coupled; homologous recombination uses a sister chromatid; non-homologous end joining is template-independent and error-prone. In post-mitotic cells the first two routes rely on a complementary strand that is itself progressively mis-info","pubDate":"2026-10-24T07:01:30Z","url":"https://doi.org/10.5281/zenodo.23611688"},"indexado":"2026-10-26T10:39:28.601Z"}}
