You See Red, I See Blue: New Study Says Color Perception Not Set, Can Be Changed

Our perception of the world around us could be very different than the person next to you.

In extreme cases it could mean the luscious red strawberry could look like a bulbous blueberry to someone else. Even more mind altering, results of new experiments with monkeys suggest that these receptors can be altered, allowing us to see colors we have never seen before and possibly helping reverse blindness.

In work published in the scientific journal ‘Nature’, colour vision scientist Jay Neitz from the University of Washington injected a virus into monkeys’ eyes which enabled them to see red as well as green and yellow.

Remarkably the group of squirrel monkeys were able to make sense of the new information despite their brains not being genetically programmed to respond to red signals.

The result was that just four months later the monkeys could see in full colour for the first time.

As well as allowing colour-blind humans to tell red from green, the innovative technique could restore sight to the blind.

Could color blindness really be a thing of the past? Does it make you wonder how different the world looks outside of your own head? How freaked out are those monkeys right now? Is this basically Pleasantville for them?

Paper Copy of 122 Year-Old Record Played Back!

Sunday, July 1st, 2012

In an awesome case of 1890s cutting-edge tech meeting modern technology, sound historian (yes…that’s a job) at Indiana University, Patrick Feaster, has done something amazingly nerdy and fantastic.

While looking for an illustration of the world’s oldest recording studio for a talk he was giving on Thomas Edison’s recordings, Feaster pulled a book for research. Upon glancing at the index, he noticed there was an article on the gramophone. When he turned to the article? A paper print of the actual recording.

In February of this year, Feaster had done something amazing with these old paper prints of the recordings…

He played them back.

By scanning these paper copies Feaster is able to unwind or ‘de-spiral’ the line that the needle would follow on the physical record. Remarkably these unwound spirals look a lot like a modern audio file. Using special software, Feaster is able to then play back the audio captured from a flat photo.

Feaster had already done this twice with two other recordings. What makes this recording interesting is that it predate his other finds.

“In that recording, Berliner tells us he’s making a record for Rosenthal to experiment with,” Feaster says. “He shares that they’re in this particular building in Hanover, and then he recites some poetry, sings a song and counts to 20 in several languages.”

According to Feaster and his colleagues what he accidentally stumbled across was the earliest known gramophone recording ever made…printed out on paper…and played back 122 years later.
