Seeing like a butterfly: Optical invention enhances camera capabilities

Butterflies can see more of the world than humans, including more colors and the field oscillation direction, or polarization, of light. This special ability enables them to navigate with precision, forage for food and communicate with one another. Other species, like the mantis shrimp, can sense an even wider spectrum of light, as well as the circular polarization, or spinning states, of light waves. They use this capability to signal a “love code,” which helps them find and be discovered by mates.

Self-assembling, highly conductive sensors could improve wearable devices

By Sarah Small

To advance soft robotics, skin-integrated electronics and biomedical devices, researchers at Penn State have developed a 3D-printed material that is soft and stretchable — traits needed for matching the properties of tissues and organs — and that self-assembles. Their approach employs a process that eliminates many drawbacks of previous fabrication methods, such as less conductivity or device failure, the team said.  

They published their results in Advanced Materials.  

Atoms in advanced alloys find preferred neighbors when solidifying

A discovery that uncovered the surprising way atoms arrange themselves and find their preferred neighbors in multi-principal element alloys (MPEA) could enable engineers to “tune” these unique and useful materials for enhanced performance in specific applications ranging from advanced power plants to aerospace technologies, according to the researchers who made the finding.
