In water, soil and air all around us lives a free-living, single-celled organism called Acanthamoeba. Most of the time, Acanthamoeba keeps to itself. On rare occasions, though, the amoeba infects humans and can cause severe infections of the eyes, skin and even the brain. What's more, doctors can struggle to diagnose and treat the eye infection caused by the organism, called Acanthamoeba keratitis. https://phys.org/news/2026-09-eye-amoeba-resists-treatment-biochemistry.html Cell & Microbiology Thu, 01 Oct 2026 11:00:02 EDT news709919162 While talks on an international plastics treaty remain deadlocked, California is starting a process that could lead to microplastics regulation.
