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 ...

Oldest insect resource pulses revealed by fossils from China

Resource pulses, i.e., occasional episodes of ephemeral resource superabundance, represent a fundamental mechanism by which energy, nutrients, and biomass are transported across ecotones. They are widespread in extant ecosystems; ...

New imaging spectrometer surveys atmospheric dust from the ISS

Scientists on Earth will soon see our planet's atmospheric dust sources in high resolution, as a new state-of-the-art imaging spectrometer—developed by NASA's Jet Propulsion Laboratory (JPL) and Cornell University—aims ...

Exploring monoatomic platinum catalysts

What happens when a cat climbs onto a sunflower? The sunflower is unstable, will quickly bend, and the cat will fall to the ground. However, if the cat only needs a quick boost to catch a bird from there, then the sunflower ...
