This is probably the most incredible tech discovery of all this to me. Insane how it can just be absorbed by the body with no side-effects.
- bioemerl 4y ago> The team made the electrodes from a metal called molybdenum, which is widely used in electronic and semiconductor applications. They discovered that when molybdenum is thin enough, it can biodegrade. Furthermore, it does not interfere with the healing process. Fda limits the metal to 2 mg a day.

- victorbjorklund 4y agoIt is less than the recommended dosage: https://news.ycombinator.com/item?id=35074916 https://news.ycombinator.com/item?id=35074916 (sure if you also get from food it might end up more but the upperlimit is probably way higher than the RDA)
- knodi123 4y agoI had a steel splinter in my thumb once. It turned gray, and then just faded, over a span of 6 months or so. I was disappointed, because I could use it to feel magnetic fields, which was really neat.
- dbcurtis 4y agoYeah… just don’t get an MRI
- bioemerl 4y agoWhy not?
- Rhapso 4y agoIt may get ripped out by the superconducting magnet. Perhaps not in a desirable direction of "out" either (your fingernail won't stop it) In practice most people notice something is wrong before there is bloodshed.
