Optical illusions, mirages that don't deceive
The aim of this paper is to dispel the excessively widespread myth that optical illusions are errors of the visual system. In 1978, Stanley Coren and Joan Stern Girgus published one of the most significant works of scientific literature in the last few decades, entitled "Seeing is Deceiving: The Psychology of Visual Illusions". view more (2006-07-24)
New Research Shows Consistency in Synaesthetic Experiences
A quirky psychological phenomenon known as "grapheme-color synaesthesia" describes individuals who experience vivid colors whenever they see, hear, or think of ordinary letters and digits. view more (2008-04-30)
New Study Indicates Radiologists Need Standards to Ensure Optimal Visual Accuracy
Radiologists, like professional pilots for example, depend on good vision as part of their occupation. However, radiologists unlike pilots are not required to undergo regular vision testing. view more (2009-06-10)
2CV man - phantom menace
This is the finding of research presented today, Wednesday 29 September, by Professor Graham Davies of Leicester University, at The British Psychological Society's Division of Forensic Psychology Conference, held at Churchill College, Cambridge. view more (1999-09-13)
My favourite aunt is purple: Why some people see 'auras' around their loved ones
Supposed psychic powers that enable people to see auras around others may simply be a quirk of the brain, according to a University College London (UCL) study of a rare form of synaesthesia where some people see colourful 'auras' around their loved ones. view more (2004-10-18)
Electrochromic artificial nails
The researcher Carlos Gonzalez from the Department of New Materials at CIDETEC (Basque Country) has developed an element called electrochromic false nail. This cosmetic accessory item will be able to be used as an artificial nail to cover the natural one. Its novelty lies in the fact that, once the false nail is inserted into position, it can... view more... (2003-11-04)
Computer vision for the blind
The white cane used by the blind as a travel aid may be universal, but it is not always adequate when it comes to pedestrian crossings. Although some crossings make a sound when it is safe to cross, many do not, and it is at these crossings that the blind need to know when the green man is showing. Adaptations of the white cane have been made,... view more... (2002-08-15)
NEW DIAGNOSTIC METHOD COULD IMPROVE DETECTION OF PROSTATE CANCER (p 1849)
A new diagnostic technique using colour Doppler with an ultrasound contrast agent is more effective than conventional systematic biopsy in diagnosing prostate cancer, conclude the authors of a research letter in this week's issue of THE LANCET. Prostate cancer detection is currently based on three diagnostic tests: serum prostate-specific antigen... view more... (2001-06-06)
Star technology aids DNA analysis
University of Leicester astronomers and biologists have patented a new way of analysing DNA from gene-chips, which may be used in laboratories and hospitals to diagnose diseases from a single drop of blood and compare gene expression in different samples. The pioneering technique uses an instrument developed at the European Space Agency's... view more... (2003-11-03)
Lighting up paper
Researchers have developed a sophisticated way of measuring the print quality of paper. The work, published today in the Institute of Physics journal, Measurement Science and Technology, describes how Jari Palviainen and colleagues at the Universities of Joensuu and Oulu in Finland, use what is known as a diffractive optical element-based sensor... view more...

The numerate honey bee
The remarkable honey bee can tell the difference between different numbers at a glance. A fresh, astonishing revelation about the 'numeracy' of insects has emerged from new research by an international team of scientists from The Vision Centre, in Australia, published January 28 in the online, open-access, peer-reviewed journal PLoS ONE. view more (2009-01-28)
Ancestry attracts, but love is blind
People preferentially marry those with similar ancestry, but their decisions are not necessarily based on hair, eye or skin colour. view more (2009-11-20)
Can we 'learn to see?': Study shows perception of invisible stimuli improves with training
Although we assume we can see everything in our field of vision, the brain actually picks and chooses the stimuli that come into our consciousness. view more (2009-10-22)
From glass eyes to colour-fast digital prints
Top quality colour printing could be revolutionised thanks to the revival in Bristol of an old printing process once used to create, among other things, colour charts for selecting glass eyes. Art researchers from the University of the West of England have discovered a 21st century use for the process, known as collotype, which fell out of favour... view more... (2002-06-06)
Let Your 3D Image Star in Your Favourite Film, Video, Pop Promo or Computer Game
The new 3D model can be imported into computer generated scenes using standard 3D modelling packages for the PC/Mac. The new technology captures a 3D model of a person from a set of colour images. Compared with available 3D laser-scanning based technologies the new approach is relatively low-cost and captures models with a high-quality appearance.... view more... (1999-08-24)
Looking forward to better travel
These were the findings of a study published today, Monday 15 November, in the British Journal of Psychology, by Mark Turner of Portsmouth University, and Professor Michael Griffin of Southampton University's Institute of Sound and Vibration Research. view more (1999-11-15)
Rough day at work? You won't feel like exercising
Have you ever sat down to work on a crossword puzzle only to find that afterwards you haven't the energy to exercise? Or have you come home from a rough day at the office with no energy to go for a run? view more (2009-09-25)
The science behind why leaves change colour in the Autumn
Autumn is marked out by spectacular changes in leaf colour as the greens of summer change into the yellows and reds of autumn. In parts of North American whole tourist industries are based on this change, but why do leaves turn these bright colours before falling off the trees? view more (2004-10-04)
Mystery behind the strongest creature in the world
The strongest creature in the world, the Hercules Beetle, has a colour-changing trick that scientists have long sought to understand. view more (2008-03-11)
Names turn preschoolers into vegetable lovers
Do you have a picky preschooler who's avoiding their vegetables? A new Cornell University study shows that giving vegetables catchy new names - like X-Ray Vision Carrots and Tomato Bursts - left preschoolers asking for more. view more (2009-03-02)
