Nutrient-poor oceans generate their food "hot spots"
The oceans have their desert zones, in other words areas poor in nutrients and unfavourable for phytoplankton to develop. Half of the southern Pacific thus consists of great expanses of warm water with an average temperature of 28 °C (a greater surface area than Europe), which receives no input of deep-source cold water, rich in nutrient... view more...

Third of eye strain complaints about computer monitors indicate workplace dissatisfaction
One in three complaints of eye strain, attributed to computer monitors, is really about employee dissatisfaction with working conditions, suggests research in Occupational and Environmental Medicine. Over 200 banking employees completed three questionnaires on job stress, environmental working conditions, and levels of eye strain as a result of... view more... (2001-03-12)
Penn researchers report that gene therapy awakens the brain despite blindness from birth
Researchers at the University of Pennsylvania have demonstrated that gene therapy used to restore retinal activity to the blind also restores function to the brain's visual center, a critical component of seeing. view more (2007-06-26)
Research may unlock mystery of autism's origin in the brain
In the first study of its kind, researchers have discovered that in autistic individuals, connections between brain cells may be deficient within single regions, and not just between regions, as was previously believed. view more (2007-08-23)
'Fluorescent' cells give early warning for eye disease
Scientists at the University of Michigan have shown that their new metabolic imaging instrument can accurately detect eye disease at a very early stage. view more (2008-02-25)
The aye-ayes have it: The preservation of color vision in a creature of the night
A quest to gain a more complete picture of color vision evolution has led Biodesign Institute researcher Brian Verrelli to an up-close, genetic encounter with one of the world's most rare and bizarre-looking primates. view more (2007-09-05)
Cerebrospinal Fluid Restores Vision
A new method for visual impairment treatment has been discovered by researchers of the Institute of Human Brain, Russian Academy of Sciences. The patients suffering from visual impairment can be helped if a healthy donor's cerebrospinal fluid is introduced to the parent's vertebral canal - this method is called liquortransfusion. Physiologists... view more... (2004-11-01)
Visual impairment associated with increased mortality risk
Individuals age 49 and older with cataract and those age 49 to 74 years with age-related macular degeneration appear to have higher mortality rates over an 11-year period than those without such visual impairments. view more (2007-07-10)
Earthshine reflects Earth's oceans and continents from the dark side of the Moon
Researchers from the University of Melbourne and Princeton University have shown for the first time that the difference in reflection of light from the Earth's land masses and oceans can be seen on the dark side of the moon, a phenomenon known as earthshine. view more (2009-04-08)
Hand Can't Be Fooled, Study Shows
Research published in the March issue of Psychological Science, a journal of the Association for Psychological Science, is suggesting that we process images in two very distinct ways. view more (2008-03-11)
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)
Deaf-blind woman deafer than deaf-blind man
Dutch researcher Ronald Pennings has found new clinical and genetic characteristics for two different inherited syndromes that cause deaf-blindness. One of the two syndromes appears to cause more hearing impairment in women than in men. Pennings investigated Wolfram syndrome and Usher syndrome. These are two inherited syndromes that cause both... view more... (2004-05-07)
The sound of proteins
Biologists have converted protein sequences into classical music in an attempt to help vision-impaired scientists and boost the popularity of genomic biology. view more (2007-05-03)
Oxford Biomedica and the Institute of Opthalmology present preclinical results from the RetinoStat programme for vision-loss
Oxford BioMedica and The Institute of Ophthalmology are describing two key features of the Company's vision-loss product RetinoStat(TM) at The Annual Meeting of the Association for Research in Vision and Ophthalmology (ARVO), held in Fort Lauderdale, Florida, during May 4th-8th. This is the world's biggest forum for eye research and is attended by... view more... (2003-05-06)
Rapid movements of living biomolecules visualised
Dutch researcher Chris Molenaar has made the rapid movements of proteins, DNA and RNA molecules visible in living cells. With this technique researchers can study the dynamics of biomolecules in their natural environment. Molenaar developed a method which makes it possible to follow the movements of RNA molecules in living cells. The researcher... view more... (2003-06-24)
New Technology To Help Early Skin Cancer Diagnosis
Computer scientists in the UK have invented a new technology to help doctors diagnose skin cancer while it is still in its early stages, greatly improving the chances of successful treatment. The work has been carried out by a team led by Dr Ela Claridge in the University of Birmingham's School of Computer Science. The Engineering and Physical... view more... (2000-04-11)
The colour of your hair may leave you open to stereotypes and prejudice
Hair colour has been associated with stereotypes of females in western society and it appears that the stereotype of 'dumb blonde' is still alive and well. There is also some evidence that men rather than women have constructed the dumb blonde stereotype. view more (1999-03-26)
New light detector
A novel prototype light meter has been developed by researchers in New York. Published today in the Institute of Physics journal, Measurement Science and Technology, this new retinal flux density meter will provide an affordable tool for measuring light at all levels and might ultimately lead to new standards to improve both energy efficiency and... view more...

The worldwide prevalence of glaucoma is increasing (p 1711)
Early diagnosis of glaucoma is essential to prevent irreversible visual impairment, according to a Seminar in this week's issue of THE LANCET. Glaucoma is a group of disorders that progressively damage the optic nerve in the eye and without treatment can cause visual disability and eventual blindness. Glaucoma affects more than 66 million people... view more... (2004-05-19)
