Integrating Variable Signals in Hydrogels
All living organisms have systems that can link multiple signals to manage tasks. This ability, called complex signal integration, is not found in artificial systems. This new study demonstrates a pathway for simple, soft artificial materials called...

Being Exceptional in Higher Dimensions
By connecting electromagnetic waves and magnetism to create a system made of magnon polaritons, scientists demonstrated the existence of an “exceptional surface” for the first time. Exceptional surfaces were originally a purely mathematical...

Intense Light Pulses Bounce on a Crystalline Bed without Rumpling the Atomic Blanket
Scientists developed a new technique that uses intense X-ray pulses to measure how atoms move in a sheet of material one molecule thick. Scientists showed that movement of the atoms in a tungsten-selenium “blanket” layer caused the layer to...

Building Better Bridges for Moving Energy
Scientists have developed a new type of nanostructure that mimics certain natural light-harvesting systems. The new nanostructures serve as a bridge to move energy generated by light-absorbing molecules to light-emitting molecules. The transfer has...
