There have been developments in high-temperature high-pressure superconductors this year, but as far as I know this is the first claim ever of a room-temperature ambient-pressure superconductor. And not just some vague "evidence for superconductivity", but every test you could possibly want with a cooking recipe to boot. That's why it's almost certainly a hoax - it's too big of a leap from current leading edge and everything one could hope for - but if someone DID stumble onto such a recipe, this is what that discovery would look like at first.
