The Earth’s magnetic field is one of the basic abiotic factors in all environments, and organisms had to adapt to it during evolution. On some occasions, organisms can be confronted with a significant reduction in a magnetic field, termed a “hypomagnetic field—HMF”, for example, in buildings with steel reinforcement or during interplanetary flight....

Environmental pollution, waste accumulation, or lack of critical resources has become a common part of our life in society. With metals as one of the main groups of pollutants—there is a problem when they are where they should not be, however, there is also a problem when they are not where we want them to be. Surprisingly, microorganisms offer us...
