(Phys.org) —A combined team of researchers from Spain and Australia has discovered what they claim is the first known instance of a biomaterial that can kill bacteria on contact based only its physical surface structure. ...
A new study from Columbia Engineering and Harvard identified the critical physiological importance of suitable temperatures for butterfly wings to function properly, and discovered that the insects exquisitely regulate their ...

(Phys.org) —Scientists have used selective breeding to create purple wings on the normally brown-winged butterfly Bicyclus anynana. Antonia Monteiro and her colleagues selected butterflies with wing scales that reflected ...
The findings add to current knowledge of how insects fly and keep stable in the air. They could also help to inspire new designs in small aerial vehicles like drones, which can be useful for search-and-rescue attempts and ...
