Magnetic bacteria point the way

Researchers found magnetotactic bacteria living on a hydrothermal vent chimney at 2,787 meters below the ocean's surface. The discovery provides clues to the early diversification of bacteria and offers insights into the environment that may support extraterrestrial life.

Magnetic nanoparticles in biological vehicles individually characterized for the first time

A multidisciplinary research group uses magnetotactic bacteria to create nanomagnetic structures, which can be steered through the human body via external magnetic fields. They have developed a new method to measure the magnetic properties of individual nanomagnets in biological entities, enabling precise control over these structures.

Animals' magnetic 'sixth' sense may come from bacteria, new paper suggests

Researchers propose a hypothesis that animals use magnetotactic bacteria in a symbiotic relationship to gain a magnetic sense, which could improve human navigation and inform ecological research. The study found evidence of magnetotactic bacteria associated with various animal species, including sea turtles, birds, and mammals.

Researchers reveal mystery of bacterial magnetism

Researchers discovered that magnetotaxis, a phenomenon where bacteria align like tiny swimming compass needles, helps them detect lower oxygen concentrations more efficiently. This subtle advantage allows the bacteria to thrive in environments with limited oxygen, making their magnetic properties beneficial in nature.
