Two thirds of the world's blind are women
Almost two thirds of the world's blind are women, finds an analysis of published research on global blindness in the British Journal of Ophthalmology. In 2000, Africa had over 10 times the rate of blindness of the rest of the world. (2001-11-28)

Scientists don't turn a blind eye to bias
Scientific journals should insist on more robust experimental processes, say biologists after reviewing nearly 900,000 experiments. The team found that non-blind experiments -- that is, where scientists knew which samples they were recording -- averaged a 27 percent stronger result than blind trials. However, their review suggests that less than one in four experiments used blind data recording. (2015-07-09)

Early- and late-onset blind individuals show supra-normal auditory abilities in far-space
Researchers report this week that early-onset blind individuals exhibit enhanced skill in their abilities to localize sound originating at a distance and that some of these skills are even obtained by those who lose sight as adults. The findings improve our understanding of how blind individuals use auditory information from their surroundings and offer clues to how these abilities develop. (2004-10-04)

Be alert to blind cord strangulation risk, parents of young children warned
Window blind cords pose a particular risk of accidental strangulation for young children, doctors have warned in Archives of Disease of Childhood. (2013-04-29)

The blind really do hear better
Nearly everyone has heard the popular notion that the blind hear better than the sighted - possibly to make up for their inability to see. Now, researchers at the Montreal Neurological Institute, McGill University and at the Université de Montréal have shown that the blind really do hear notes more precisely but only if they became blind when they were very young. Their findings, Pitch discrimination in the Early Blind, were published in the journal Nature. (2004-07-22)

Head in the game
Researchers at the University of Tsukuba find that blind soccer players rotate their heads downward when trapping an incoming pass. This work may lead to an improved understanding of the sensory changes that can manifest in visually impaired individuals. (2020-11-24)

Do the blind have a more acute sense of smell?
An ongoing study by Mathilde Beaulieu-Lefebvre, a graduate student from the Universite de Montreal department of psychology, has debunked the myth that the blind have a more acute sense of smell than the sighted. Vision loss simply makes blind people pay more attention to how they perceive smells. (2010-04-26)

Blind people have brain map for 'visual' observations too
Is what you're looking at an object, a face, or a tree? When processing visual input, our brain uses different areas to recognize faces, body parts, scenes, and objects. Scientists at KU Leuven (University of Leuven), Belgium, have now shown that people who were born blind use a 'brain map' with a very similar layout to distinguish between these same categories. (2017-05-17)

Teaching the blind to read and recognize objects with sounds
Areas of the brain in blind people can learn to process visual input through the use of sound, even after years or perhaps even lifelong blindness, according to new research reported in the November issue of the Cell Press journal Neuron. The findings challenge the common belief that if the visual cortex of the brain is deprived of information in early life, it may never develop functional specialization. (2012-11-07)

Flamingoes, elephants and sharks: How do blind adults learn about animal appearance?
They've never seen animals like hippos and sharks but adults born blind have rich insight into what they look like, a new Johns Hopkins University study found. (2019-05-21)

Blind people are 'serial memory' whizzes
Compared to people with normal vision, those who were blind at birth tend to have excellent memories. Now, a new study reported online on June 21st in the journal Current Biology, a publication of Cell Press, shows that blind individuals are particular whizzes when it comes to remembering things in the right order. (2007-06-21)

Université de Montréal study shows superior sound-location skills in the blind
A research team led by Professor Franco Lepore, director of the Centre for Research in Neuropsychology and Cognition at the Université de Montréal, has shown that both early- and late-onset blind people have better sound discrimination abilities than people with normal vision. Reported in the latest edition of the journal Current Biology, the study demonstrates for the first time that blind people from both groups perform equally well in tests requiring them to map auditory space beyond their peri-personal environment. (2004-10-07)

UAB researchers and ONCE pioneer a new Braille keyboard
Researchers from the Universitat Autònoma de Barcelona and the Organización Nacional de Ciegos Españoles (ONCE) have developed a Braille keyboard for PCs that has some unique features.

In this week's BMJ, a pediatrician is calling for Venetian blinds to be redesigned to safeguard babies and toddlers from accidentally being strangled to death by the looped cords. (2010-06-29)

Blind more accurate at judging size than sighted
Close your eyes and imagine a loaf of bread. With your eyes still closed, estimate with your hands the size of that loaf of bread. Do you think your mental representation is an accurate one? Specifically, how accurately have you gauged its size? According to researchers from the University of Otago in New Zealand, you probably overestimated the size of the bread. That is, unless you are blind. (2005-03-28)

Numbers of blind are falling
The numbers of people in Germany who are blind or visually impaired is going down. Robert P. Finger and his co-authors present their findings in the current edition of Deutsches Aerzteblatt International. (2012-07-20)

Louisiana Tech University contributing to noise safety standards for electric vehicles
The Professional Development and Research Institute on Blindness at Louisiana Tech University is conducting human trials to determine if electric and hybrid electric vehicles traveling at low speeds provide sufficient sound to be safe for pedestrians, especially those who are blind and visually-impaired. (2015-06-02)

Brain mechanism underlying the recognition of hand gestures develops even when blind
Japanese researchers figured out that activated brain regions of congenitally blind individuals and activated brain regions of sighted individuals share common regions when recognizing human hand gestures. They indicated that a region of the neural network that recognizes others' hand gestures is formed in the same way even without visual information. The findings are discussed in The Journal of Neuroscience. (2014-09-05)

Taking sightlessness for a spin can harm people's attitudes toward blindness
Using simulation to walk in the shoes of a person who is blind -- such as wearing a blindfold while performing everyday tasks -- has negative effects on people's perceptions of the visually impaired, according to a University of Colorado Boulder study. (2015-01-14)

A bird's blind spot plays an important role in its vision
The width of a bird's visual binocular field is partially determined by the size of the blind area in front of its head, according to a study published March 29, 2017 in the open-access journal PLOS ONE by Luke Tyrrell and Esteban Fernández-Juricic from Purdue University, USA. (2017-03-29)

Researchers find everyone has a bias blind spot
Researchers have developed a tool to measure the bias blind spot, which reveals that believing that you are less biased than your peers has detrimental consequences on judgments and behaviors, such as accurately judging whether advice is useful. (2015-06-08)

Smoking linked to blindness
Smokers are up to four times as likely to become blind in later life from age related macular degeneration (AMD) than non-smokers, but many remain largely unaware of this risk, warn researchers in this week's BMJ. (2004-03-04)

Keeping an eye on intruders
Electronic fingerprinting, iris scans, and signature recognition software are all becoming commonplace biometrics for user authentication and security. However, they all suffer from one major drawback -- they can be spoofed by a sufficiently sophisticated intruder. Writing in the International Journal of Biometrics, Japanese researchers describe a new approach based on a person's reflexes that could never be copied, forged, or spoofed. (2008-09-04)

Scientists create a UV detector based on nanocrystals synthesized by using ion implantation
Scientists at the Lobachevsky University have been working for several years to develop solar-blind photodetectors operating in the UV spectral band. In the field of electronic technology, this is an important task, since such devices cut off emission with a wavelength higher than 280 nm, which helps to avoid interference from sunlight and to record UV emission during daylight. (2018-08-06)

Blind lead the way in brave new world of tactile technology
Imagine feeling a slimy jellyfish, a prickly cactus or map directions on your iPad Mini retina display, because that's where tactile technology is headed. But you'll need more than just an index finger to feel your way around. New research at UC Berkeley has found that people are better and faster at navigating tactile technology when using both hands and several fingers. Moreover, blind people outmaneuvered their sighted counterparts. (2014-07-01)

Breakthrough design opens door to 'full screen' Braille displays for the blind
Imagine if your computer only allowed you to see one line at a time, no matter what you were doing -- reading e-mail, looking at a Web site, doing research. That's the challenge facing blind computer users today. But new research from North Carolina State University is moving us closer to the development of a display system that would allow the blind to take full advantage of the Web and other computer applications. (2010-03-29)

We've all got a blind spot, but it can be shrunk
The human eye includes an unavoidable blind spot. That's because the optic nerve that sends visual signals to the brain must pass through the retina, which creates a hole in that light-sensitive layer of tissue. When images project to that precise location, we miss them. As reported in Current Biology on Aug. 31: this blind spot can be effectively 'shrunk' with training, despite the fact that the hole in our visual field cannot be. (2015-08-31)

'Embodiment awareness' research aim to help the blind learn math more quickly
Mathematical reasoning is rich in spatial imagery revealed in gestures. Funded by the NSF, researchers in the Virginia Tech Center for Human-Computer Interaction are creating tactile image technology and devices to provide blind students with elements of the imagery embodied in mathematics discourse. (2005-05-24)

'I can hear a building over there' -- researchers study blind people's ability to echolocate
Everybody has heard about echolocation in bats and dolphins. These creatures emit bursts of sounds and listen to the echoes that bounce back to detect objects in their environment. What is less well known is that people can echolocate, too. (2011-05-25)
