A surprisingly soft mineral may control how Earth recycles rocks

Knowing this is important for understanding what happens to slabs of rock as they sink into the Earth, which in turn teaches us about how and why earthquakes and volcanoes happen on the surface.

New perovskite LED emits a circularly polarized glow

LEDs led to the high-definition viewing experience we’ve come to expect from our screens. A new type of LED that utilizes spintronics could take displays to the next level.
