Researchers find retinal rods able to detect photon number distribution
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.
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 ...
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.
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.
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 ...
Biologists discover highly complex communication system in aquatic cyanobacteria
Land plants can "see," but can microscopic plants see better? New research from Indiana University has uncovered a give-and-take communication system between and within photoreceptors in freshwater-dwelling ...
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 ...
Many sharks colour blind, research confirms
(Phys.org)—New research which could help to deter and conserve sharks has confirmed that many of the ocean predators are probably completely colour blind.
Fly eye mystery: Research provides insight into why flies have fastest vision in animal kingdom
Fly eyes have the fastest visual responses in the animal kingdom, but how they achieve this has long been an enigma. A new study shows that their rapid vision may be a result of their photoreceptors - specialised ...
Circadian clock research may enable designer plants, and cancer and diabetes treatments
How does a plant know when to sprout a leaf, fold its petals or bloom? Why do humans experience jet lag after a trip abroad?
Sugar influences the onset of flowering, study finds
(Phys.org)—A plant can reproduce successfully only if it flowers at the appropriate time. Therefore, a complex network of photoreceptors and other proteins has evolved to monitor environmental conditions ...
Team uses carbon nanotubes for polarized-light detection
Using carpets of aligned carbon nanotubes, researchers from Rice University and Sandia National Laboratories have created a solid-state electronic device that is hardwired to detect polarized light across ...
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 ...
