Scientists map brains of the blind to solve mysteries of human brain specialization
New research suggests unexpected brain connectivity can lead to fast brain specialization, allowing humans to adapt to the rapid technological and cultural innovation of our generation Studying the brain activity of blind people, scientists at the Hebrew University of Jerusalem are challenging the standard view of how the human brain specializes to perform different kinds of tasks, and shedding new light on how our brains can adapt to the rapid cultural and technological changes of the 21st Century.

Echolocation: a 'sixth sense' for blind people
Could echolocation - a skill commonly linked with bats - be used as a "sixth sense" for blind people? Researchers have found that blind people using echolocation are just as susceptible to visual illusions as sighted people. Echolocation is a process whereby sound waves are used to determine the location and size of objects within a particular area. Returning sound waves rebounding from objects provide positional information to those that are unable to see them.

Groundbreaking wireless material may restore sight to blind retinas
The aging process affects everything from cardiovascular function to memory to sexuality. Most worrisome for many, however, is the potential loss of eyesight due to retinal degeneration. New progress towards a prosthetic retina could help alleviate conditions that result from problems with this vital part of the eye. An encouraging new study published in Nano Letters describes a revolutionary novel device, tested on animal-derived retinal models, that has the potential to treat a number of eye diseases.

Macular degeneration may respond to new laser therapy
A new type of laser treatment has the potential to slow progression of age-related macular degeneration - a major cause of vision loss - without damaging the retina. This was the conclusion of a study from the University of Melbourne in Australia, published in The FASEB Journal. Erica Fletcher, an associate professor in Melbourne's Department of Anatomy and Neuroscience, and colleagues examined the effectiveness of a new low-impact, low-energy, laser treatment for patients with early age-related… [ 530 more words. ]

Southampton experts find glaucoma drug can boost eyelash growth
Eye experts at Southampton's university hospitals have discovered a drug used to treat glaucoma can boost the growth and prominence of eyelashes. In a year-long trial, researchers at Southampton General Hospital and Saint Louis University in the US analysed the effects of a daily application of bimatoprost to the upper eyelid of patients with poor eyelash growth, known as idiopathic hypotrichosis, or eyelash loss as a result of recent… [ 324 more words. ]
