Un equipo internacional convirtió cáscaras de arroz desechadas en un filtro de biocarbón que capturó dos tintes industriales tóxicos en pruebas de laboratorio y mantuvo su eficacia durante al menos cinco ciclos de uso. La técnica podría reducir los residuos agrícolas y limpiar aguas; el siguiente paso será probarla a escala más grande.

Reishülsen werden zu mehrfach nutzbarem Filter für Farbstoffe

PHYS

Ein internationales Team hat weggeworfene Reishülsen zu einem Filter auf Biokohlebasis verarbeitet, der im Labor zwei giftige Industriefarbstoffe auffing und mindestens fünfmal ohne Wirkungsverlust wiederverwendet werden konnte. Der Ansatz könnte Agrarabfall mindern, muss jedoch noch anhand realer Wasserproben geprüft werden.

Researchers have developed a deepfake detection method that reads the naturalness of facial expressions rather than searching for visual glitches. Tested on standard benchmark datasets, it achieved over 95% accuracy and caught manipulations that defeated most existing detectors.

Kenya, Ghana, Namibia, and Mali now require minerals to be processed domestically before export, ending the colonial pattern that extracted resources while leaving factories elsewhere. By controlling the value chain, these governments build industrial capacity and keep profits at home rather than shipping raw ore abroad.

From August 27, households across the UK will be able to install approved plug-in solar kits by connecting them to a standard wall socket. The new rules set technical safety limits and fulfill the government's pledge to legalize the systems before summer ends, making small-scale solar power more accessible.
