Article: > They squeezed a droplet of room-temperature water between the pointy ends of two cut diamonds. By the time the pressure raised to about a gigapascal, roughly 10 times that at the bottom of the Marianas Trench, the water had transformed into a tetragonal crystal called ice VI. By about 2 gigapascals, it had switched into ice VII, a denser, cubic form transparent to the naked eye that scientists recently discovered also exists in tiny pockets inside natural diamonds. Actual paper: > Double-distilled, deionized water was loaded in diamond anvil cells (DACs) with 200×200μm quartz plates either 15 or 30μm thick and four ruby microspheres, then compressed at room temperature to 2.5GPa to form ice VII. A great example of science journalism translating technical language into vernacular.
