Magnetic coils, the new way to deal with microplastics

Flowing through rivers and oceans, plastic waste has become an important environmental threat across the globe. Trying to deal with the problem, researchers in Australia developed a way to purge water sources of microplastic without harming microorganisms, using a set of magnets.   Microplastics are ubiquitous pollutants. Some are too small to be filtered during industrial water treatment, such as
