Excellent Underwater Vision Examined by Scientists from Lund
We humans are poorly adapted for underwater vision. However, the Moken peoples of south-east Asia manage to collect shells, clams and sea cucumbers using no visual aids when diving to a depth of 3 or 4 metres. Scientists from Lund University in Sweden have now measured the visual acuity of these children and have found that their ability to see... view more... (2003-05-15)
Ground-breaking research to develop 'conscious' robot
Researchers at the Universities of Essex and Bristol will soon be launching a ground-breaking project to develop a 'conscious' robot. The aim of the project, which involves computer scientists and neuropsychologists, is to advance the technology of intelligent machines, while also extending the understanding of human consciousness. Owen Holland,... view more... (2003-08-22)
Quantitative PET Imaging Finds Early Determination of Effectiveness of Cancer Treatment
With positron emission tomography (PET) imaging, seeing is believing: Evaluating a patient's response to chemotherapy for non-Hodgkin lymphoma (NHL) typically involves visual interpretation of scans of cancer tumors. view more (2007-10-24)
Scientists adapt economics theory to trace brain's information flow
Scientists have used a technique originally developed for economic study to become the first to overcome a significant challenge in brain research: determining the flow of information from one part of the brain to another. view more (2008-10-10)
Infliximab Could Prevent Sight Loss From Behcet's Disease (p 295)
A drug used to treat rheumatoid arthritis and Crohn's disease could play an important role in preventing sight loss associated with the inflammatory disorder Behcet's disease, suggest authors of a fast-track research letter published in this week's issue of THE LANCET. Beh'§et's disease is a rare condition (although with increased incidence in... view more... (2001-07-25)
Experts examine causes, treatment and prevention of glaucoma
Although scientists know progressive degeneration of retinal ganglion cells and their axons is the primary cause of glaucoma, researchers have yet to identify a way to stop or prevent the degeneration. view more (2009-03-05)
Neural noise created during binocular rivalry
Neural "noise" may cause you to miss important changes in your environment when you are concentrating on something else, new research indicates. view more (2009-06-19)
Humans perceive others' fear faster than other emotions
You may not be fully dressed without a smile, but a look of horror will make a faster first impression. Vanderbilt University researchers have discovered that the brain becomes aware of fearful faces more quickly than those showing other emotions. view more (2007-10-15)
Caltech neurobiologists discover individuals who 'hear' movement
Individuals with synesthesia perceive the world in a different way from the rest of us. Because their senses are cross-activated, some synesthetes perceive numbers or letters as having colors or days of the week as possessing personalities, even as they function normally in the world. view more (2008-08-07)
Scans show learning 'sculpts' the brain's connections
Spontaneous brain activity formerly thought to be "white noise" measurably changes after a person learns a new task, researchers at Washington University School of Medicine in St. Louis and the University of Chieti, Italy, have shown. view more (2009-10-09)

Test for visual acuity could aid detection, rehabilitation of AMD
A computer-based method for evaluating the eye's ability to distinguish object details and shape in patients with age-related macular degeneration (AMD) could provide a more accurate way to assess the effectiveness of eye surgery or vision rehabilitation interventions with devices and training, according to a Canadian study. view more (2007-10-30)
Shape encoding may start in the retina
New evidence from the University of Southern California suggests that there may be dedicated cells in the retina that help compile small bits of information in order to recognize objects. view more (2007-09-12)
Pioneers in field of functional genomics work toward gene therapy for vision defects
"Primates and humans have three photoreceptors and can only see four basic colors, red, green, blue and yellow," says Jay Neitz, Ph.D. "Birds, fish and reptiles have four photoreceptors, allowing them to see things we cannot. They must see an entire dimension of color, including ultraviolet, infrared and all the combinations... view more... (2006-12-12)
New interview technique could help police spot deception
Shifting uncomfortably in your seat? Stumbling over your words? Can't hold your questioner's gaze? Police interviewing strategies place great emphasis on such visual and speech-related cues, although new research funded by the Economic and Social Research Council (ESRC) and undertaken by academics at the University of Portsmouth casts doubt on... view more...

New study explores the relationship between preterm birth and autism spectrum disorder
Recent studies have suggested that autism spectrum disorder (ASD) may be more prevalent among children born very prematurely. The early symptoms of ASD are also associated with other conditions related to preterm births, such as cerebral palsy, which can make it difficult to correctly screen children for ASD. view more (2009-01-29)
Vision improvement after gene therapy maintained at 1 year for inherited retinal blindness
One year after a trio of young adults received gene therapy for an inherited form of blindness, researchers have documented that the patients are still experiencing the same level of remarkable vision improvements previously measured within weeks. view more (2009-08-13)
Face-to-face contact in a virtual environment
Although many sectors of the telecommunications industry are eagerly awaiting a ray of hope on the economic horizon, the prospects for video conferencing systems look good: Last year, sales on the European market increased by almost 15 percent, and the consultant Frost & Sullivan predicts that the growth rate will exceed 20 percent next year.... view more...
