Un robot que funciona con luz y materiales vivos abre la puerta a dispositivos más livianos, menos contaminantes y capaces de moverse en lugares donde hoy no entra nada. Para el lector de acá, es una señal de hacia dónde puede ir la tecnología del futuro: menos máquinas de metal y más sistemas que aprovechan la naturaleza. Lo que todavía no se sabe es cuánto tiempo aguantan las algas vivas y cuánta fuerza pueden generar en la práctica.","quienFirma":"Universidad Tecnológica de Delft (Países Bajos)","confianza":"revisado","consulta":null},"sello":{"hash":"1e5fac6f2cf809ec56747cf1cdb9f8997530aeab18c16aa9750529c3bf56444b","sello":"a6da40e0b1f1731a1d505cb60153876f8cfb9a021f494eaad5cb88f35deb40a9","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6574370,"aleatorio":"84f8fd67881ec5c0111cd4650a2f570a1f4f3e7e0693dd127fcc10831236eb10","tiempo":"2026-10-22T09:42:00.000Z"},"nist":{"cadena":2,"pulso":1994390,"salida":"8792E321C8EE15F6129299EB06189C646F898E2C000FAAFC8D7EA7BD3B4067BFFB3D603CC2408578E12D6F2C2AED0D35A8DA7764BD2FAF00BD14B707B0DDF7BD","tiempo":"2026-10-22T09:41:00.000Z"},"noAntes":"2026-10-22T09:42:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 22 09:42:15 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Algae-powered soft robot arm uses light to grasp and lift small objects","descripcion":"Tiny underwater algae sway gently in the current. All of a sudden, a light shines on them and they form robotlike arms that start to pick up small rocks and put them in floating baskets. Sounds like science fiction, but researchers from Delft University of Technology (the Netherlands) have created a small soft robot arm covered with minuscule algae that can grasp and lift objects. And it's powered by light. This next step in biotechnology has been published in Nature Communications.","pubDate":"Thu, 22 Oct 2026 05:39:19 EDT","url":"https://phys.org/news/2026-10-algae-powered-soft-robot-arm.html"},"indexado":"2026-10-22T09:41:56.225Z"}}
