Night Vision Camouflage, Inspired By Squid
University of California-Irvine scientists combined a protein found in a chameleon-like squid with graphene to create a material that could be used to hide people and objects in infrared light.
What's the Latest Development?
Engineers at the University of California-Irvine have created a material that they say could provide better camouflage for military personnel and vehicles at night. They did it with the help of the longfin squid, which contains in its skin a protein that lets them change their color and texture so that they are harder to see in infrared light. Combining this protein with graphene results in a coating that can be activated under certain biological or chemical conditions. A paper describing the research appeared in an issue of Advanced Materials.
What's the Big Idea?
Infrared light as used in cameras and night vision goggles makes it easier to see people and objects in the dark, especially since its reflective properties are different for fabrics and materials. Tests done with an orange surface coated with the material showed that it blended into green foliage when the coating was activated. UC-Irvine professor Alon Gorodestsky says the eventual goal "is to create fabrics that can dynamically alter their texture and colour to adapt to their environments. Basically, we’re seeking to make shape-shifting clothing...a reality."

What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.

As Game of Thrones ends, a revealing resolution to its perplexing geography.
- The fantasy world of Game of Thrones was inspired by real places and events.
- But the map of Westeros is a good example of the perplexing relation between fantasy and reality.
- Like Britain, it has a Wall in the North, but the map only really clicks into place if you add Ireland.
