EPFL researchers have discovered that Vanadium Dioxide (VO2), a compound used in electronics, is capable of "remembering" the entire history of previous external stimuli. This is the first material to be identified as possessing this property, although there could be others.

MIT engineers have developed a paper-thin loudspeaker that can turn any surface into an active audio source.

Imagine a battery that could be recharged for decades. No more getting rid of cell phones because of waning battery life. No more landfills filled with lithium ion batteries. This is one step closer to reality, thanks to work by researchers from the University of California at Irvine.
