Mining with Microbe “Animal Magnetism”
They’re microscopic miners. Some species of aquatic bacteria draw in dissolved iron from their watery environment and store it in specialized compartments called magnetosomes. They use its magnetic properties to navigate, sort of like ancient mariners using a lodestone to keep their bearings. Arash Komeili, Professor of Plant and Microbial Biology and one of this year’s Bakar Fellows, aims to understand what controls and maintains the microbes’ novel traits.
