Lithium-ion batteries produce faint sounds as they charge, discharge, and degrade. But until now, nobody could interpret those sounds to detect when a battery might be about to lose power, fail, or burst into flames.

Earthquakes are driven by energy stored up in rocks over millennia—energy that, once released, we perceive mainly in the form of the ground’s shaking. But a quake also generates a flash of heat and fractures and damages underground rocks. And exactly how much energy goes into each of these three processes is exceedingly difficult to
Under 10% of an earthquake’s energy makes the ground shake Read More »
