Brett Smith for redOrbit.com - Your Universe Online While strolling through the woods late at night, you may be lucky - or unlucky - enough to see a pair of glowing eyes floating in the darkness and staring back at you. Wild animals’ glowing eyes aren’t just a great way to scare human campers or hikers, they are a byproduct of their boosted night vision, which is the result of a layer of tissue in the eye called the tapetum lucidum (TL), which sits behind the retina and reflects...

Area Of The Brain That Creates Illusory Shapes And Surfaces Discovered By Scientists
2013-10-01 11:10:48

Vanderbilt University The logo of the 1984 Los Angeles Olympics includes red, white and blue stars, but the white star is not really there: It is an illusion. Similarly, the "S" in the USA Network logo is wholly illusory. Both of these logos take advantage of a common perceptual illusion where the brain, when viewing a fragmented background, frequently sees shapes and surfaces that don't really exist. "It's hallucinating without taking drugs," said Alexander Maier, assistant...

Scientists reveal how organic mercury can interfere with vision More than one billion people worldwide rely on fish as an important source of animal protein, states the United Nations Food and Agriculture Organization. And while fish provide slightly over 7 per cent of animal protein in North America, in Asia they represent about 23 per cent of consumption. Humans consume low levels of methylmercury by eating fish and seafood. Methylmercury compounds specifically target the central...

Sharon Kleyne reports on high risk places for Dry Eye and Eye Dehydration. Grants Pass, OR (PRWEB) August 20, 2013 Complaints related to dry eye, a condition resulting from dehydration or water loss in the eye’s basal tear film, are the number one reason for United States Ophthalmologist visits. Water and Health Researcher and Power of Water radio host Sharon Kleyne recently reported on the places most likely to cause dry eye discomfort. The comments were based on her own research and...

Dragonflies May Help Improve Robotic Vision Systems

[ Watch the Video: Dragonflies Hunt Food Like Humans ] April Flowers for redOrbit.com - Your Universe Online What do a dragonfly and a robot have in common? Nothing yet, but researchers at the University of Adelaide have discovered a novel and complex visual circuit in a dragonfly’s brain that might someday help to improve vision systems for robots. The underlying processes of insect vision have been the research subject for Dr Steven Wiederman and Associate Professor David...

Scientists working at the Research Center on Aging at the Health and Social Services Centre — University Institute of Geriatrics of Sherbrooke (CSSS-IUGS) have been studying strategies for protecting retinal pigment epithelium (RPE) cells. Dysfunction of the RPE is found in retinopathy and age-related macular degeneration, which is the leading cause of blindness of elderly people in developed countries. Findings published today in the Canadian Journal of Physiology and Pharmacology...

Animal study reveals “unexpected” role of horizontal cells in photoreceptor rod and cone cell development of retina Scientists are developing a clearer picture of how visual systems develop in mammals. The findings offer important clues to the origin of retinal disorders later in life. In research published this week in the Journal of Neuroscience, University at Buffalo scientists and colleagues focused on a particular protein, called a transcription factor, that regulates gene...

Red Lights At Night Better Than White When It Comes To Mood
2013-08-07 11:32:35

Brett Smith for redOrbit.com - Your Universe Online People working the graveyard shift may want to literally see red because according to a new study -- the color of light animals are exposed to at night can affect mood regulation. Study researchers from The Ohio State University found hamsters that were exposed to blue lights at night experienced the worst mood disruptions, followed closely by white lights, when compared to hamsters that spent their nights in a dim red light. "Our...
