One such ion channel passes only calcium, a protein that’s crucial for transmitter release and thus for neurons to talk to each other. In experiments using cloned calcium ion stations in embryonic kidney cells, the scientists found that nickel and yttrium, two steel catalysts used to form the single-walled carbon nanotubes, were interfering with the ion channel’s ability to absorb the calcium. Because its ionic radius is nearly identical to calcium’s, yttrium in particular ‘gets prevents and stuck calcium from entering and passing through.
