Magnetosome Mysteries

Aquatic, motile bacteria that orient and rate along geomagnetic field Iines,known as gnetotactic bacteria, were discovered three de cades ago by Richard P. Blakemore, then a uate student at the University of Massachusetts at Amherst, Initially considered a mere osity, these bacteria have gained celebrity tus as well as deeper respect among scientists, engineers, and the general public. Thus, magnetotactic bacteria have newfound relevance in several disciplines beyond pure microbiology, including nanobiotechnology, biomineralization, biogeochemistry, geomicrobiology, and magnetosensory behavior in animals, These bacteria are also considered relevant subject matter by those searching for signs of life on Mars, Despite progress elucidating the how and why of magnetotaxis, many questions remain rega rding the fascinating behavior of these organisms. Indeed, both physicists and micro biologists are trying to unlock the secrets of these microbes. Fortunately, scientists from both disciplines naturally tend to love magnetota ctic bacteria, not least because they are fun and safe to study.
