Highly branched, cross-linked polymer membranes can effectively remove carbon dioxide and hydrogen sulfide during hydrogen purification, even at high pressures.

Experiments on an analog of a major mineral in Earth's deepest mantle imply that alignment of mineral grains by flow could explain observed seismic signals.

Laboratory selection for tobacco hornworms that change color when warm produces a polyphenism, in which one genome yields alternative phenotypes in different environments.
