A gene that makes cells in the eye receptive to light is missing in humans, researchers have discovered.   view more (2006-10-13)

Making mice with enhanced color vision
Researchers at the Johns Hopkins School of Medicine and their colleagues have found that mice simply expressing a human light receptor in addition to their own can acquire new color vision, a sign that the brain can adapt far more rapidly to new sensory information than anticipated.   view more (2007-03-23)

Retina transplants show promise in patients with retinal degeneration
Preliminary research shows encouraging results with transplantation of retinal cells in patients with blindness caused by retinitis pigmentosa (RP) and age-related macular degeneration (AMD).   view more (2008-07-11)

Transport interrupted — Texas A&M biologists trace cause of early blindness to tissue defect
Researchers at Texas A&M University are shedding light on a rare form of early blindness, identifying the cells involved and paving the way for possible therapies to treat or even prevent what is currently an incurable disease.   view more (2007-03-08)

Researchers link melanopsin gene to unexplored light detection system within the eye.
Discovery could explain why light keeps us awake and may lead to new treatments for disorders such as jet-lag and SAD. Researchers from Imperial College London, Johns Hopkins University, USA and Brown University, USA have discovered that melanopsin, a recently identified protein, plays a key role... view more (2003-01-08)

NYU Researchers id new class of photoreceptors,pointing to new ways sights-and smells-are regulated
The identification of a new class of photoreceptors in the retina of fruit flies sheds light on the regulation of the pigments of the eye that confer color vision, researchers at New York University's Center for Developmental Genetics report in a new study appearing in the Public Library of... view more (2008-04-22)

Research could lead to new treatments for blindness
Scientists have discovered how to make cells sensitive to light in what may lead to a new approach to treating certain forms of blindness.   view more (2005-01-24)

Transplanted photoreceptor precursor cells restore visual function in mice with retinal degeneration
Scientists have successfully transplanted light-sensing cells called photoreceptors directly into the eyes of mice and restored their visual function.   view more (2006-11-09)

New Evidence on How our Eyes use Light to Manage our Body Clock - University of Surrey Groundbreaking Study Results
A new study published this week shows for the first time that the human eye is sensitive to short wave length visible light and transmits information to the body clock in a way that may make it possible to manipulate waking and sleeping rhythms. This new data, gained from a study carried out at the... view more (2001-08-20)

Research shows NPD1 protects a key component of vision
Two papers to be published in the Early Edition online of the Proceedings of the National Academy of Sciences (PNAS) the week of July 30-August 3, 2007 report findings that demonstrate that neuroprotectin D1 (NPD1) protects against damage to retinal pigment epithelial (RPE) cells and identifies an... view more (2007-07-31)

More evidence mammals, fruit flies share make-up on function of biological clocks
A study by researchers at New York University and the University of London offers additional evidence that mammals and fruit flies share a common genetic makeup that determines the function of their internal biological clocks. The study appears in the latest issue of Current Biology.   view more (2006-03-07)

Viagra®, unlikely tool for vision research, slows the visual response to flickering light
Therapeutic doses of Viagra¬Æ have been shown to influence the rate at which visual signals are integrated by the brain, affecting the way quick, repeated events, such as flickering light, are perceived.   view more (2006-01-24)

Behavioral studies show UV contributes to marsupial color vision
Work reported this week provides new evidence that marsupials, like primates, have functional color vision based on three different types of color photoreceptor cones-but unlike primates, a component of marsupial color vision includes sensitivity to ultraviolet wavelengths.   view more (2006-03-21)

Successful tests of new treatments in mice for eye disease causing irreversible blindness in humans
A team led by Krzysztof Palczewski, Ph.D., chair of pharmacology at the Case Western Reserve University School of Medicine, has taken the first steps in treating an eye disease causing irreversible congenital blindness in millions of people worldwide by successfully testing two new treatments in... view more (2005-11-02)

Researchers discover way to make cells in the eye sensitive to light
Researchers have discovered a way to make light sensitive cells in the eye by switching on a single gene.   view more (2005-01-24)

Not So Different After All: Mysterious Eye Cells Adapt To Light
A new retinal photoreceptor adjusts its sensitivity in different lighting conditions, according to scientists at Brown University, where the rare eye cells were discovered.   view more (2006-01-06)

Antioxidants may slow vision loss
Scientists at Johns Hopkins have successfully blocked the advance of retinal degeneration in mice with a form of retinitis pigmentosa (RP) by treating them with vitamin E, alpha-lipoic acid and other antioxidant chemicals.   view more (2006-07-20)

New fruit fly protein illuminates circadian response to light
Researchers at the University of Pennsylvania School of Medicine have identified a new protein required for the circadian response to light in fruit flies.   view more (2006-06-30)

'Lucky 13' as new gene discovery offers further hope for childhood blindness
An international research team has discovered a gene that, when mutated, causes one of the most common forms of inherited blindness in babies.   view more (2007-06-12)

One gene provides fruit fly both antenna and color vision
A team of researchers that includes biologists from Washington University in St. Louis has discovered that a gene involved in the development and function of the fruit fly antenna also gives the organism its color vision.   view more (2006-04-05)

MiniBooNE findings clarify the behavior of neutrinos
The initial data from the 10-year long "MiniBooNE" experiment at the Department of Energy's Fermilab significantly clarifies the overall picture of how the neutrino fundamental particles behave.   view more (2007-04-12)
