Magnetotactic bacteria remove and recover rare elements

While our human biochemical reactions are limited, our ingenuity is not, and scientists are able to exploit microbes for our benefit, such as in chemical spills. Using microbes to degrade or sequester toxic molecules is one form of bioremediation, and has many various applications. Famously, sci... Read More
