Scientists Unveil Bionic Robo-fish To Remove Microplastics From Seas (theguardian.com) 21
Scientists have designed a tiny robot-fish that is programmed to remove microplastics from seas and oceans by swimming around and adsorbing them on its soft, flexible, self-healing body. From a report: Microplastics are the billions of tiny plastic particles which fragment from the bigger plastic things used every day such as water bottles, car tyres and synthetic T-shirts. They are one of the 21st century's biggest environmental problems because once they are dispersed into the environment through the breakdown of larger plastics they are very hard to get rid of, making their way into drinking water, produce, and food, harming the environment and animal and human health.
"It is of great significance to develop a robot to accurately collect and sample detrimental microplastic pollutants from the aquatic environment," said Yuyan Wang, a researcher at the Polymer Research Institute of Sichuan University and one of the lead authors on the study. Her team's novel invention is described in a research paper in the journal Nano Letters. "To the best of our knowledge, this is the first example of such soft robots." Researchers at Sichuan University have revealed an innovative solution to track down these pollutants when it comes to water contamination: designing a tiny self-propelled robo-fish that can swim around, latch on to free-floating microplastics, and fix itself if it gets cut or damaged while on its expedition.

How toxic are microplastics? Really. (Score:1, Troll)
No study that simulates actual real-world exposure has shown microplastics to be clearly harmful to fish or mammals, let alone humans. For example, this study https://www.nature.com/article... [nature.com] dosed up mice on quantities when scaled up to human levels is like being given IV microplastics for days. Even so the toxicity wasn't all that bad, which is the real surprise. I'm shocked the mice didn't just say fuck all this plastic and die.

Fish have been seen to eat microplastics instead of real food, and consequently starving. It is a real threat to whole species in the food chain. The food chain that humans are at the top of.

I think you're conflating two things: microplastics, which are too small to see (or eat), and plastic trash, which certainly would harm fish that tried to eat it.

If we don't detox the ocean then there might be even more people without food or shelter.

Better idea... stop using plastics so that we don't have to fish the micro plastics out of the water. We need more $$$ put into research into alternatives that are sustainable. Plastics are not the way forward into the future.
