Folks have known for years that adding magnesium to media rescues the lethality of deleting many 'essential' genes, but why? @eswaralab.bsky.social and @subtisilly.bsky.social say that free iron builds up in these mutants. Mg2+ mitigates this by redirecting metabolism towards limiting ROS production

How animals sense Earth’s magnetic field is one of biology’s enduring mysteries.
