Squids and octopuses are masters of camouflage, blending into their environment to evade predators or surprise prey. Some aspects of how these cephalopods become reversibly transparent are still "unclear," largely because ...

The right mixture of salts to get life started

In modern organisms, the hereditary material DNA encodes the instructions for the synthesis of proteins—the versatile nanomachines that enable modern cells to function and replicate. But how was this functional linkage ...

From ribbon to scroll: Gaining shape control by electrostatics

Northwestern Engineering materials science researchers have uncovered new insights into how electrostatic interactions can be regulated to attain and control scroll-like cochleate structures, which could inform how to capture ...
