One of the most influential science studies of all time started with a modest minicomputer, some simulated boxes of water molecules, and a grand vision for computer-aided chemistry. The year was 1982.

Ice cubes float in water because they’re less dense than the liquid. But a newfound type of ice has a density nearly equal to what’s in your water glass, researchers report in the Feb. 3 Science. If ...

Today IonQ announced that its quantum computer has achieved a critical milestone: simulating the water molecule with accuracy approaching what is needed for practical applications in the promising ...
