ESA contributes to ocean carbon cycle research
The Earth's oceans play a vital role in the carbon cycle, making it imperative that we understand marine biological activity enough to predict how our planet will react to the extra 25 000 million tonnes of carbon dioxide humans are pumping into the atmosphere annually. view more (2008-05-06)
Color Vision Drove Primates to Develop Red Skin and Hair, Study Finds
You might call it a tale of "monkey see, monkey do." Researchers at Ohio University have found that after primates evolved the ability to see red, they began to develop red and orange skin and hair. view more (2007-05-25)
Impaired vision common in US
A new report estimates that approximately 14 million people aged 12 years and older in the U.S. have vision impairment, of which more than 80 percent could be improved with the use of corrective lenses. view more (2006-05-10)
Alcohol cravings and anxiety do not increase with repeat detoxification
People with alcohol problems have no greater anxiety or cravings after the second, third or fourth detoxification than the first, according to a new study by experimental psychologists at the University of Sussex. Previous studies have shown that the risk of seizures can increase with subsequent detoxifications due to the effects of withdrawal... view more... (2002-06-14)
Giant Pandas See in Color
They may be black and white, but new research at the Georgia Institute of Technology and Zoo Atlanta shows that giant pandas can see in color. view more (2006-10-16)
Study Highlights Need For UK Childhood Screening For Amblyopia (pp 597, 621)
Authors of a study in this week's issue of THE LANCET highlight how the risk of visual loss in the normal eye for individuals with one lazy eye (amblyopia) is greater than previously thought, strengthening the need for effective screening programmes to detect amblyopia in early childhood. Monocular amblyopia occurs in at least 1% of individuals... view more... (2002-08-21)
OHSU eye doctor says laser surgery safer than contacts
Traditional assumptions have held that contact lenses are safer than laser surgery to correct vision problems. view more (2006-10-10)
Early brain activity sheds new light on the neural basis of reading
Most people are expert readers, but it is something of an enigma that our brain can achieve expertise in such a recent cultural invention, which lies at the interface between vision and language. view more (2009-04-28)
Flower power
A plastic "energy flower'' that collects solar and wind energy that can then be used to power appliances in the home for free has won a Northumbria University student a top award. Paul Richardson, a third year design student, won a £1,750 Design International Attachment Award from the RSA (Royal Society for the encouragement of Arts,... view more... (2002-05-24)
Multiple genes permit closely related fish species to mix and match their color vision
Vision, like other biological attributes, is shaped by evolution through environmental pressures and demands, and even closely-related species that are in other ways very similar might respond to their particular environments by interpreting the visual world slightly differently, using photoreceptors that are attuned to particular wavelengths of... view more...

Laser treatment not effective in preventing vision loss for people with early AMD
According to a study that appears in the November 2006 issue of the journal Ophthalmology, researchers at the University of Pennsylvania School of Medicine and 21 other clinical centers have found that low-intensity laser treatment-thought to be potentially beneficial in slowing or preventing the loss of vision from age-related macular... view more...

Vision restoration therapy shown to improve brain activity in brain injured patients
Columbia University Medical Center researchers have demonstrated using functional magnetic resonance imaging (fMRI), that brain activity was increased in stroke and traumatic brain injury survivors who underwent Vision Restoration Therapy (VRT), a rehabilitative treatment that helps these patients recover lost vision. view more (2007-08-14)
Fish vision discovery makes waves in natural selection
Emory University researchers have identified the first fish known to have switched from ultraviolet vision to violet vision, or the ability to see blue light. The discovery is also the first example of an animal deleting a molecule to change its visual spectrum. view more (2009-10-19)
Early vision screening associated with better eyesight in children with amblyopia
Children who screen positive for amblyopia, reduced vision in one eye, before age 2 appear to have better visual outcomes than those whose vision problems are detected during screenings between ages 2 and 4. view more (2008-04-15)
Which came first: Primates' ability to see colorful food or see colorful sex?
The adaptive significance of the unique ability in many primates to distinguish red hues from green ones (i.e., trichromatic color vision) has always enticed debate among evolutionary biologists. view more (2007-06-27)
Sight for sore eyes
An inventive breakthrough from the Applied Optics Group at the University of Kent at Canterbury (UKC) is set to revolutionise current methods of eye examinations. Professor David Jackson, Dr Adrian Podoleanu and Dr John Rogers, who gained his doctorate at Kent, have developed an instrument known as an Optical Dual Channel Tomograph. The instrument... view more... (2002-03-13)
More effective treatment identified for common childhood vision disorder
Scientists have found a more effective treatment for a common childhood eye muscle coordination problem called convergence insufficiency (CI). view more (2008-10-16)
Penn researchers find treatment for MS also reduces vision loss in MS patients
According to a study that appears in the April 17 issue of Neurology, researchers at the University of Pennsylvania School of Medicine have found that natalizumab (TYSABRI®) - a drug that slows disability and reduces relapse rates in patients with multiple sclerosis (MS) - also reduces vision loss in patients with relapsing MS. view more (2007-04-17)
Seeing Through the Skin
Feeling blue? According to Prof. Leonid Yaroslavsky from Tel Aviv University, the saying may be more than just a metaphor. view more (2008-09-12)
Refractive errors affect vision for half of American adults
About half of U.S. adults age 20 and older have refractive errors, or eye problems that result in less than 20/20 vision, according to a report in the August issue of Archives of Ophthalmology, one of the JAMA/Archives journals. view more (2008-08-12)
