Scientists in the UK think they may have found a cheap, low-tech way to help fight age-related loss of vision. In a small clinical trial, people over 40 who were told to stare into a deep red light for three minutes a day had noticeable improvements to their sight. They reported being able to see better in the dark and to better distinguish colors.
It will still be a while before scientists are able to harness Superman-like laser vision, but the technology is now closer than ever before thanks to a new development from the University of St Andrews. The team there have created an ultra-thin membrane laser using organic semiconductors, which is for the first time compatible with the requirements for safe operation in the human eye. Even though the membrane is super thin and flexible, it’s durable, and will retain its optical properties even after several months spent attached to another object, such as a bank note or, more excitingly, a contact lens.
A picture is worth a thousand words. You have to see it to believe it. Pics or it didn’t happen. The trust we put into visual cues is all but encoded into our language. But what happens when the visual information itself is a lie? How effective are we at teasing out fact from optical fiction? Not very, according to a recent study in the journal Cognitive Research: Principles and Implications.
Taste, smell, vision, hearing, touch and… awareness of one’s body in space? Yes, humans have at least six senses, and a new study suggests that the last one, called proprioception, may have a genetic basis.
What’s the Number One question demanded of self-styled audio experts like me? “How much power do I need?”
It may sound like something out of “Star Trek”: Doctors have implanted a device in patients that has restored some central vision after advanced eye disease left those individuals with only limited peripheral vision. This is the first time that artificial and natural vision has ever been integrated in humans, the U.K.-based research team said.
Scientists have used stem cells to cure blindness in rabbits—which could be incredible news for visually impaired people.
