Self-folding origami machines powered by chemical reactions

A Cornell-led collaboration harnessed chemical reactions to make microscale origami machines self-fold—freeing them from the liquids in which they usually function, so they can operate in dry environments and at room temperature.

Carbon sink models need nitrogen, says study

Nitrogen is necessary when predicting how land plants will take up atmospheric carbon. That's because nitrogen's future trajectory will diverge from that of other factors of plant growth in the coming decades, according to ...
