'Floppy' atomic dynamics help turn heat into electricity

Materials scientists at Duke University have uncovered an atomic mechanism that makes certain thermoelectric materials incredibly efficient near high-temperature phase transitions. The information will help fill critical ...

Songbirds, like people, sing better after warming up

If you've ever been woken up before sunrise by the trilling and chirping of birds outside your window, you may have wondered: why do birds sing so loud, so early in the morning?

AI may offer a better way to ID drug-resistant superbugs

Biomedical engineers at Duke University have shown that different strains of the same bacterial pathogen can be distinguished by a machine learning analysis of their growth dynamics alone, which can then also accurately predict ...

Young dolphins pick their friends wisely

Strategic networking is key to career success, and not just for humans. A new study of wild bottlenose dolphins reveals that in early life, dolphins devote more time to building connections that could give them an edge later ...

Green is more than skin-deep for hundreds of frog species

Frogs and toads are green for a very good reason—it makes them harder to see in their leafy environments. Good camouflage allows them to eat and not be eaten. But not all frogs have arrived at this life-saving greenness ...
