Astronauts need oxygen. Magnets could help

Scientists discovered that magnets can improve oxygen production in space by helping remove gas bubbles during electrolysis. Unlike the ISS's bulky spinning system, magnets efficiently dislodge bubbles from electrodes in zero gravity, potentially enabling more feasible Mars missions. The magnetic field creates two effects - making water slightly magnetic and causing fluid swirling - that help collect oxygen bubbles for astronaut life support systems.
