First material found to "remember" its own history
Researchers at EPFL have discovered a material that seems to be able to "remember" all of its past encounters with stimuli, such as electrical currents. The compound could come in handy for better data storage and processing. The material in question is vanadium dioxide (VO 2), and it's already known to have some intriguing properties.
