Humans are reason for why domestic animals have strange and varied coat colors
HUMANS have actively changed the coats of domestic animals by cherry-picking rare genetic mutations, causing variations such as different colours, bands and spots, according to a new study. view more (2009-01-16)
Hoverflies stripe off in summer heat
Ecologists are unraveling the reasons behind seasonal differences in insects’ colour patterns, a question that has puzzled them since the 1970s. Speaking at the British Ecological Society’s Winter Meeting, to be held at the University of Warwick on 18–20 December 2001, Anne Halpin and Dr Graham Holloway of the University of... view more...

Why green Twixes might be better than beige ones
Chocolate bars and other supermarket products might sell better from green-coloured point-of-sale stands, Cathrine Jansson will tell delegates at a meeting of the SCI (Society of Chemical Industry) on 3 March. She will be previewing results of new research on the effect of colour on consumers' behaviour which suggests that we spot green items... view more... (2004-02-25)
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)
Why Plants Talk To Insects - New Research from Imperial At Chelsea Flower Show (22-25 May)
Why talking to insects is so important to a plant's well-being is the theme of an unusual display at this year's Chelsea Flower show (22-25 May). The display, jointly staged by Imperial College at Wye and the ICI subsidiary, Quest International, will show how plants use scent and colour to attract helpful insects and to repel unwelcome herbivores.... view more...

New optic fibre sensors capable of detecting organic compounds
This new research is presented in the Navarre chemist, Mar'a Asunci'³n Luquin's PhD, "Synthesis and characterisation of de vapochromic substances for their implementation in optic fibre environmental sensors". The PhD has been presented in Public University of Navarre. view more (2004-10-26)
Patterns on tropical marine mollusk shell mirror gene expression patterns
Scientists have identified a group of genes that control the formation of shapes and colour patterns on the shell of the tropical marine mollusc referred to as 'abalone'. view more (2006-11-22)
NYU scientists set stage for understanding how color vision is processed
New York University biologists have mapped the medulla circuitry in fruit flies, setting the stage for subsequent research on how color vision is processed. view more (2008-03-26)
Vision and hearing loss often occur together in older age
Older adults with vision loss may be more likely to also have hearing loss, and the opposite appears true as well. view more (2006-10-10)
'Twinkle' eye test could improve AMD diagnosis
Scientists at UCL (University College London) have developed a more reliable test for detecting vision loss in people with age-related macular disease (AMD), the leading cause of blindness in the UK and US. The method, which centres on a visual illusion, could lead to earlier self-diagnosis of sight deterioration - encouraging patients to access... view more... (2007-10-25)
Near vision research study
The Cornea and Laser Eye Institute is participating in a research study to determine if an investigational corneal inlay can safely and effectively reduce the need for reading glasses. Dr. Peter Hersh, the study doctor, will perform the procedures. view more (2009-11-06)
VTT technology helps in the assembly of microscopic components
Nowadays, micro-sized components that are invisible to the human eye are already being used both in electronics products and elsewhere. Components range from a millimetre to a micrometre in size and are getting even smaller. VTT has developed a unique prototype machine viewer system for use in the assembly and quality inspection of parts in this... view more... (2001-12-05)
Test allows early detection of vision problems in infants with hemangiomas of eyelids
In children with vascular birthmarks around the eye, even partial blockage of vision can lead to visual loss due to amblyopia. view more (2009-04-01)
Vision impairment costs billions lost in productivity
Corrected vision impairment could prevent billions of dollars in lost productivity annually. view more (2009-06-03)
Kingston Computing Expert Charts Amputees' Rehabilitation
New Kingston University research could reduce the recovery time for lower limb amputees by helping health professionals chart patients' progress more easily. Tom Geake, from Kingston's Mobile Information and Network Technologies Research Centre, has designed a new method of interpreting results from the locomotor capabilities index, used by... view more...

Aston University researchers gain insight into diabetic vision problems
Diabetes is one of the major causes of vision loss and blindness in the UK. Now optometry researchers at Aston University's new £10 million Academy of Life Sciences are to carry out a ground-breaking new study which will lead to a greater understanding of visual problems experienced by diabetics. view more (2004-08-24)
Pressable photonic crystals produce full-colour fingerprints and promise enhanced security
In the future, law enforcement officials may take full-colour fingerprints using new technology developed by a University of Toronto-led team of international researchers. view more (2006-03-15)
Early treatment of macular degeneration with macugen may help patients preserve their vision
Age-related macular degeneration (AMD) is the leading cause of blindness in older patients in the developed world. view more (2005-10-07)
Research Councils unveil a vision for research
The grand challenges for the future in UK research and the benefits that will come from them is the focus of the Research Councils UK report 'A Vision for Research', published this week. From discovering what the universe is made of to advances in the philosophy of language, the report sets out key areas for research over the next ten to twenty... view more... (2003-12-12)
New nationwide study will evaluate effect of antioxidants and fish oil on progression of AMD
The National Institutes of Health (NIH) announces a nationwide study to see if a modified combination of vitamins, minerals, and fish oil can further slow the progression of vision loss from AMD, the leading cause of vision loss in the United States for people over age 60. view more (2006-10-12)
