University of Tokyo-led researchers embedded heat-stable enzymes in four compostable plastics and tested films and microbeads at sea. Some cutinase-treated films lost nearly all mass within five months at 757 metres, while controls barely changed; PBAT degraded far less, and sustainability remains broader than biodegradation.

Des enzymes accélèrent la dégradation de plastiques en mer

PHYS

Une équipe menée par l’Université de Tokyo a intégré des enzymes thermostables à quatre plastiques compostables, puis testé films et microbilles en mer. Certains films contenant de la cutinase ont presque entièrement perdu leur masse en cinq mois à 757 mètres; le PBAT s’est beaucoup moins dégradé.

A two-year pilot in Peru’s Asháninka region gave 211 Indigenous participants unconditional cash transfers worth about £2 a day. The results? Almost 90% of them adopted practices such as reforestation and reduced burning, while food insecurity fell.

Robots and AI will digitize around 70 million UK museum specimens, from insects and pressed plants to fossils and rocks, cutting work once estimated at centuries to about a decade. The open database should help researchers track species decline, climate impacts and changes in food and pest systems.
