Stay focused: Algae-inspired polymers light the way for enhanced night vision

Researchers processed sulfur, and algae and plant compounds, into an elastic lens that maintains substantial variable focus in infrared imaging. This development will be useful in policing, firefighting, ecology, and many other applications where it's critical to see detail at variable distances in dark environments, such as at night or through smoke.
