Eye reflections can identify criminals

A new study published in PLOS ONE shows that the high resolution images produced by modern digital cameras can be used to identify the photographer and other individuals positioned behind the camera. The researchers, from the University of York (U.K.), say that images retrieved from subjects’ corneal reflections could be especially important when the images […]

Eyes used to measure pleasure response




The brain’s pleasure response to tasting food can be accurately measured through the eyes using a common, low-cost ophthalmological tool, say Drexel University researchers who believe the method could be used by both food scientists and clinicians. Study leader Jennifer Nasser details the use of electroretinography (ERG) to measure dopamine levels in the retina in […]

Antibiotic oomph: the eyes have it




Berkeley scientists have found that small fragments of a keratin protein in the eye are exceptionally efficient at killing off pathogens, a discovery the researchers believe could lead to new and inexpensive antimicrobial drugs. Details of cytokeratin 6A’s antimicrobial properties appear in the Journal of Clinical Investigation. The researchers, led by Suzanne Fleiszig, came upon […]

Mind-reading through the eyes




Scientists say they may be able to glean information about stored memories and past events by tracking a subject’s eye movements, even when the subject is unable – or unwilling – to describe what they remember. The research, appearing in the journal Neuron, shows the relationship between activity in the hippocampus, eye movements, and both […]

Insight Into Eye Evolution Deals Blow To Intelligent Design




How complex and physiologically remarkable structures such as the human eye could evolve has long been a question that has puzzled biologists. But in research reported this week in Current Biology, the evolutionary history of a critical eye protein has revealed a previously unrecognized link between certain components of sophisticated vertebrate eyes – like those […]

Retina Adapts By Suppressing The Commonplace




The retina actively seeks novel features in the visual environment, dynamically adjusting its processing in order to seek the unusual while ignoring the commonplace, say researchers at Harvard University. Their report on the principle of visual novelty detection appears in the journal Nature. The study’s findings provide evidence that the ultimate goal of the visual […]
