Tiny Cage Traps Dangerous Chemicals in Water Forever

People have invented a brand new filter using super-small cages [tiny structures made of special materials] that catch dangerous chemicals called PFAS that pollute our drinking water. This filter is amazing because it can grab even the trickiest types of these chemicals that old filters couldn't catch, and it works over and over again without wearing out. Soon, this discovery could mean cleaner, safer water for people everywhere!
