Built-in Biological Sunscreen Allows Mantis Shrimp To See The Reef In A Whole Different Light
2014-07-04 03:48:19

Cell Press In an unexpected discovery, researchers have found that the complex eyes of mantis shrimp are equipped with optics that generate ultraviolet (UV) color vision. Mantis shrimp's six UV photoreceptors pick up on different colors within the UV spectrum based on filters made from an ingredient other animals depend on as built-in biological sunscreen, according to research reported in the Cell Press journal Current Biology on July 3. "The mantis shrimp visual system contains six...

Research May Help Prevent Eye Injuries Among Soldiers
2014-06-30 03:30:57

By K.C. Gonzalez, University of Texas at San Antonio Researchers at UTSA are discovering that the current protective eyewear used by our US armed forces might not be adequate to protect soldiers exposed to explosive blasts. According to a recent study, ocular injuries now account for 13 percent of all battlefield injuries and are the fourth most common military deployment-related injury. With the support of the U.S. Department of Defense, UTSA biomedical engineering assistant...

University of California - San Diego Some neurons turn to neighbors to help take out the trash It's broadly assumed that cells degrade and recycle their own old or damaged organelles, but researchers at University of California, San Diego School of Medicine, The Johns Hopkins University School of Medicine and Kennedy Krieger Institute have discovered that some neurons transfer unwanted mitochondria – the tiny power plants inside cells – to supporting glial cells called astrocytes...

NIH/National Eye Institute NIH-funded study could help improve retinal prosthetic devices In laboratory tests, researchers have used electrical stimulation of retinal cells to produce the same patterns of activity that occur when the retina sees a moving object. Although more work remains, this is a step toward restoring natural, high-fidelity vision to blind people, the researchers say. The work was funded in part by the National Institutes of Health. Just 20 years ago, bionic...

Surveyed U.S. Payers Will Accept High Yearly Costs for Effective Novel Treatments, According to Findings from Decision Resources Group BURLINGTON, Mass., June 4, 2014 /PRNewswire/ -- Decision Resources Group finds that surveyed U.S. retinal specialists are highly willing to prescribe key emerging therapies for the treatment of geographic atrophy (GA), the dry form of advanced age-related macular degeneration (AMD). In particular, clinicians expect to prescribe Roche/Genentech's lampalizumab...

Grapes Help Support Eye Health
2014-05-30 03:30:50

California Table Grape Commission New research presented this week at the Association for Research in Vision and Ophthalmology conference in Orlando, Florida suggests that regular grape consumption may play a role in eye health by protecting the retina from deterioration. Specifically, a grape-enriched diet resulted in a protective effect on retinal structure and function. The retina is the part of the eye that contains the cells that respond to light, known as photoreceptors. There are...

redOrbit Staff & Wire Reports - Your Universe Online A few decades ago, instruments capable of tapping into a person’s nervous system to help restore movement, sensations or cognitive function seemed impossible. Now, however, the National Science Foundation (NSF) has released a how-to guide for those interested in building their own brain-machine interfaces (BMIs). Guide author and AAAS Science and Technology Policy Fellow Valerie Thompson recruited the engineers behind the Argus...
