A UK-designed robotic fish called Gilbert can remove microplastics from water and one day may be able to power itself.
Tiny shards of plastic called microplastics are all over the environment and even inside human bodies. Researchers have found a type of bioengineered algae that can clean up these pesky particles.
The turtle, named Porkchop, was rescued in March 2025 from tangled fishing line wrapped around its flipper, keeping it from swimming away.
