Layered liquids arrange nanoparticles into useful configurations

Materials scientists at Duke University have theorized a new "oil-and-vinegar" approach to engineering self-assembling materials of unusual architectures made out of spherical nanoparticles. The resulting structures could ...

Droughts could hit aging power plants hard

Older power plants with once-through cooling systems generate about a third of all U.S. electricity, but their future generating capacity will be undercut by droughts and rising water temperatures linked to climate change. ...

Dolphin smarts

Imagine you are blindfolded and placed into a pool of water with a dolphin. The dolphin performs a movement, such as spinning in a circle, or swimming in a zig-zag pattern, and your task is to imitate this movement, without ...
