Brittlestars use crystal lenses to spot approaching predators unique “visual” system is the first of its kind to be discovered in animals inhabiting the earth today

Brittlestars, also known as serpent stars, possess a unique 'visual' system that enables them to detect shadows and escape from predators. Their skeletal elements feature crystal lenses that transmit light to their nervous system, allowing them to respond to light changes.

Exploring the frontier of ultra-small electronics

Two Cornell University researchers are working on separate projects to develop new devices that could lead to huge increases in data storage and processing speed. George Malliaras is investigating the electrical properties of individual molecules, while Robert Buhrman is studying spin manipulation and quantum manipulation.
