Chemists discover how blue light speeds blindness

Blue light from digital devices and the sun transforms vital molecules in the eye's retina into cell killers, according to optical chemistry research at The University of Toledo.

Sharp-eyed robins can see magnetic fields

(PhysOrg.com) -- It has been known for decades that some birds are able to sense the Earth's magnetic field and set their direction as if following a compass heading, which is an extremely useful ability for birds migrating ...

Fossilised 429-mln-year-old eye mirrors modern insect vision

An exquisitely well preserved 429-million-year-old eye from a marine creature that went extinct before dinosaurs even existed had vision comparable to modern-day bees and dragonflies, researchers said Thursday.

Single-celled predator evolves tiny, human-like 'eye'

A single-celled marine plankton evolved a miniature version of a multi-cellular eye, possibly to help see its prey better, according to University of British Columbia (UBC) research published today in Nature.

Scientists solve mystery of the eye

(PhysOrg.com) -- Scientists have a good overall understanding of human vision: when light enters our eyes, it is focused by the lens and strikes the retina in the back of the eye. The light causes some of the millions of ...

New invisibility cloak hides objects from human view

For the first time, scientists have devised an invisibility cloak material that hides objects from detection using light that is visible to humans. The new device is a leap forward in cloaking materials, according to a report ...
