X-Cubed

Kanani Lee’s lab studies a little-known layer near the planet’s core, about 1,800 miles beneath the surface and 257 times deeper than the deepest place on the ocean floor.

For Kanani Lee, a geophysicist working at Yale, the key to reconstructing the earth’s history is high pressure. Her lab is known as the X-cubed lab, which stands for “Exploring Extremes Experimentally.” The lab studies a little-known layer near the planet’s core, about 1,800 miles beneath the surface and 257 times deeper than the deepest place on the ocean floor. At that depth, the temperature is about forty times hotter than a Finnish sauna. The pressure there is about twenty times that required to make. . . Read more
