Cells Use ‘Bioelectricity’ To Coordinate and Make Group Decisions
While Galvani was later proven wrong in the details, he wasn’t totally off. Virtually every cell on every branch of the tree of life expends a hefty chunk of its energy budget — in some cells, more than half — on maintaining a voltage…

The oxygen you breathe depends on a tiny ocean ingredient
The next time you take a breath, it is worth remembering that much of that oxygen can be traced back to microscopic ocean algae. Their ability to produce oxygen through photosynthesis is supported by iron dust that settles into the sea.
A new…
