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.

Nature as a model for greener cities

Swapping concrete and asphalt for trees, ponds and green roofs is an example of how cities can be adapted to cope with heavy rain and climate change. But time is running out. For nature-based solutions to have a global impact, ...

Study sheds light on ancient microbial dark matter

Bacteria are literally everywhere—in oceans, in soils, in extreme environments like hot springs, and even alongside and inside other organisms including humans. They're nearly invisible, yet they play a big role in almost ...
