Shapeshifting microrobots can brush and floss teeth

A shapeshifting robotic microswarm may one day act as a toothbrush, rinse, and dental floss in one. The technology, developed by a multidisciplinary team at the University of Pennsylvania, is poised to offer a new and automated ...

Nano-rust: Smart additive for autonomous temperature control

The right temperature matters—whether in technical processes, for the quality of food and medicines, or the lifetime of electronic components and batteries. For this purpose, temperature indicators record (un)desired temperature ...

How the first biomolecules could have been formed

The chemical precursors of present-day biomolecules could have formed not only in the deep sea at hydrothermal vents, but also in warm ponds on the Earth's surface. The chemical reactions that may have occurred in this "primordial ...
