A trapped positron, cooled almost to absolute zero and held away from every wall, can now be nudged one quantum at a time to test antimatter.

The Vatican better have Robert Langdon on speed dial.

That is a bit terrifying, a small amount of antimatter can make a giant hole

A single proton is way smaller than small amount

Not really tbh.

Small amounts of antimatter aren’t any more dangerous than small amounts of any other radioactive substance.

A PET scan is a medical procedure that involves injecting antimatter into the bloodstream

Well, it's not antimatter that they inject. Its a radio isotope which has a decay that produces some antimatter. It exists for an extremely small amount of time before getting annihilated.
