Mantis shrimp have the world's best eyes—but why?
As humans, we experience an amazing world of colour, but what can other animals see? Some see much more than us, but how they use this vision is largely unknown.
Chickens 'one-up' humans in ability to see color
(PhysOrg.com) -- Researchers at Washington University School of Medicine in St. Louis have peered deep into the eye of the chicken and found a masterpiece of biological design.
Aiming to cure deafness, Stanford scientists first to create functional inner-ear cells
Deep inside the ear, specialized cells called hair cells detect vibrations in the air and translate them into sound. Ten years ago, Stefan Heller, PhD, professor of otolaryngology at the Stanford University ...
Researchers find retinal rods able to detect photon number distribution
An 'eye catching' vision discovery
Nearly all species have some ability to detect light. At least three types of cells in the retina allow us to see images or distinguish between night and day. Now, researchers at the Johns Hopkins School of ...
Dogs, maybe not, but old genes can learn new tricks
A popular view among evolutionary biologists that fundamental genes do not acquire new functions was challenged this week by a new study in the Proceedings of the National Academy of Sciences.
Evolutionary bestseller in image processing
The eye is not just a lens that takes pictures and converts them into electrical signals. As with all vertebrates, nerve cells in the human eye separate an image into different image channels once it has been ...
Researchers report progress using iPS cells to reverse blindness
Researchers have used cutting-edge stem cell technology to correct a genetic defect present in a rare blinding disorder, another step on a promising path that may one day lead to therapies to reverse blindness ...
Visual system of marine annelids offers insights into the evolution of eyes
Larvae of the marine bristle worm Platynereis dumerilii orient themselves using light. Early in their development, these larvae swim towards the light to use surface currents for their dispersal. Older larvae ...
Scientists shed new light on how retina's hardware is used in color vision
Biologists at New York University and the University of Wurzburg have identified, in greater detail, how the retina's cellular hardware is used in color preference. The findings, published in the latest issue of the Proceedings of ...
Ants pay high price for night life
(Phys.org) —Despite being night creatures, Australian bull ants have trouble finding their way home in the dark. Scientists at Australia's Vision Centre (VC) have found that bull ants that travel at night ...
Nanosized diamonds enable progress in retinal prostheses
Research groups in several countries are making progress in retinal prosthesis development. If they achieve their aims, patients who have gone blind, due to loss of their photoreceptors, could recover a better ...
Scientists explore how mercury could interfere with vision
(Phys.org) —People have long heard that carrots are good for their eyesight, and strong evidence exists that eating fish also provides health benefits.
Inside the colourful world of animal vision
As humans, we live in a colourful world, but differences in visual systems means that not all animals see the world in the same way.
