Disruption of glucose transport to rods and cones shown to cause vision loss in RP
Ophthalmology researchers at the University of Louisville have discovered the loss of vision in RP is the result of a disruption in the flow of nourishing glucose to the rods and cones. This disruption leads to the starvation of the photoreceptors. In addition, the failure in glucose metabolism in RP is similar to changes seen in lung cancer. (2019-07-30)

Mismatched eyes help squid survive ocean's twilight zone
Biologists have gathered the first behavioral evidence that cockeyed squids' mismatched eyes evolved to spot two different sources of light available in the deep sea. Their one large eye is adapted for gazing upwards, searching for shadows of fellow sea creatures against fading sunlight, while their small eye is adapted for gazing downwards, scanning deeper water for bioluminescent flashes, according to researchers at Duke University and the Monterey Bay Aquarium Research Institute (MBARI).

Can we 'learn to see?': Study shows perception of invisible stimuli improves with training
Although we assume we can see everything in our field of vision, the brain actually picks and chooses the stimuli that come into our consciousness. A new study in the Association for Research in Vision and Ophthalmology's Journal of Vision reveals that our brains can be trained to consciously see stimuli that would normally be invisible.

FAU researchers and collaborators receive $2.8 million NIH grant
Researchers will work to define the mechanisms that govern how cells decide whether to become a mature cell or whether to die. This 'to be or not to be' decision is at the heart of discovering those cell controls that determine for example how healthy cells become cancer cells and how stem cells become organs. Understanding these controls is critical in learning how to make transplantable tissues to cure human disease. (2016-02-04)

When one side does not know about the other one
Whenever we are doing something, one of our brain hemispheres is more active than the other one. However, some tasks are only solvable with both sides working together. Martina Manns and Juliane Roemling are investigating, how such specializations and cooperations arise. Based on a pigeon model, they are proving for the first time in an experimental way, that the ability to combine complex impressions from both hemispheres, depends on environmental factors in the embryonic stage.

Happy, angry or neutral expressions? Eyes react just as fast
Dr Louisa Kulke from the University of Göttingen has investigated how our eyes and brain react when we see emotionally charged or neutral faces. She combined eye-tracking and electroencephalography (EEG). The result: reflex-like eye movements are independent of the expression a face shows; our attention is drawn to them just as fast. The study was published in the journal Neuroscience. (2019-10-14)
