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.

Scientists slow aging by engineering longevity in cells

Human lifespan is related to the aging of our individual cells. Three years ago a group of University of California San Diego researchers deciphered essential mechanisms behind the aging process. After identifying two distinct ...

A simple paper test could offer early cancer diagnosis

MIT engineers have designed a new nanoparticle sensor that could enable early diagnosis of cancer with a simple urine test. The sensors, which can detect many different cancerous proteins, could also be used to distinguish ...
