This is one of my key takeaways as well. It's a shame they didn't include their magnetization measurements, even if it didn't confirm superconductivity. The first conclusive paper will have to demonstrate a superconducting tr

YBCO which has a critical temperature of around 90K has a critical field in excess of 250T. So 9T is not expected to weaken superconductivity much for a sample with a critical temperature of 110K.

The jump looks like bad contacts to me. The wires you attach undergo stress during the cooldown, and such artefacts can happen with small samples. Rewiring the sample should get rid of it.

The jump at 250K looks like bad contacts to me that fixed themselves during cooldown. Rewiring the sample and remeasuring should get rid of it. The field dependence is indeed a bit weird. One would expect the critical temperature to reduce

This is my first comment on this material, because I've been skeptical, but this result shouldn't be understated. It basically confirms the existence of a new family of high-temperature superconductors, the first of its kind since

I had to give it 3-4 days before I got some activity. Any flour should work as long as it is unbleached. I've had good success with just Sainsbury's strong white bread flour. It has given me a fragrant peachy starter.

The only connection to black holes that I could find is, that they use mathematics first developed for string theory [1], so it's bit tenuous to say superconductors are related to black holes. Once you read a few of these articles you
