A property of electrons is that the mass of the electron increases by a few orders of magnitude as it is super cooled. At or close to absolute zero while the mass has increased thousands of times the electrons super conduct. Weird critters.

I find this discussed here. These "electrons" are excited states of certain solids involving the conduction bands. It is axiomatic in solid state physics that a "particle" is "an excited state of a system", and this is most evident with "phonons", or quantized vibrations of a solid. So, this sort of talk shouldn't be taken to imply any sort of modification of the electron as an elementary particle.
