Superconductivity in a metal alloy disappears upon application of a moderate magnetic field, but surprisingly reappears in a strong field, when the directions of electronic spin rotate.

The structure of a large metal-organic framework useful for storing gas shows that it has pores 12 to 15 angstroms across that form eight binding sites for argon and nitrogen.

Differences in seismic waves generated by nearly identical earthquakes occurring years apart confirm that Earth's inner core is rotating more rapidly than the rest of the planet.
