(Phys.org)—Sodium ions are key regulators in cellular processes. The fluids in cells, whether it is water, blood plasma, or nutrients, are regulated by the sodium concentration in cells. If scientists could study sodium ...
Like a surgeon separating conjoined twins, cells have to be careful to get everything just right when they divide in two. Otherwise, the resulting daughter cells could be hobbled, particularly if they end up with too many ...
