Good news! Are we getting closer to room temperature superconductors? Although, this article seems to be more on the exotic side and not a breakthrough.
"Superconductivity observed in “twisted” bilayers of the two-dimensional (2D) material graphene requires the layers to be carefully stacked on top of each other at a very precise angle. Zhou et al. found superconductivity in the most common form of bilayer graphene, called Bernal, which does not require such precise manipulation ... The researchers subjected the samples to an external electric field, but superconductivity emerged only after they also turned on an in-plane magnetic field. This unusual effect of a magnetic field, which normally acts to suppress superconductivity, is suggestive of exotic, spin-triplet pairing in Bernal-stacked bilayer graphene"
