For decades, that thermal ceiling has been one of the hardest walls in engineering.A team at the University of Southern California may have just found a way around it. In a study in Science, researchers from the USC Viterbi School of Engineering and the USC School of Advanced Computing report a new type of electronic memory device that kept working reliably at 700 degrees Celsius, hotter than molten lava and far beyond anything previously achieved in its class. The device showed no signs of reaching its limit. Seven hundred degrees was simply as hot as their testing equipment could go.
