South Korean scientists transmit broadband signals through a human arm

Posted in News by Conner Flynn on March 16th, 2010

Need a hand with your data? How about an arm? Turns out that human skin is a very energy-efficient conduit for transmitting data. And why not? It can transmit electricity. In fact, a recent experiment achieved a rate of 10Mbps. In the experiment they used small, flexible electrodes.

The news might lead to new medical devices that can monitor blood sugar or electrical activity in the heart. Devices that could cut energy needs for a monitoring network by about 90 percent compared to wireless devices that run on batteries.

Swiss scientists identify PlayStation-induced skin disorder

Swiss scientists identify PlayStation-induced skin disorderAh, the Swiss. While Germans have been busy doing useful things with street lighting, the Swiss have been busy treating people who actually still play a Sony console for injuries.

Here’s the story. Swiss scientists have ID’d a new skin disorder that they believe came from prolonged gaming. They’re calling it “PlayStation palmar hidradentitis,”, a condition where painful lumps appear on the palms. The diagnosis came when a 12-year old girl visited a Geneva hospital with hand lesions. Allegedly from a gaming marathon that lasted hours. She fully recovered after a ten-day break from the PlayStation.

Scientists extract images directly from the brain

Scientists extract images directly from the brainIn what could be the first step toward recording your dreams, researchers from Japan’s ATR Computational Neuroscience Laboratories have developed new brain analysis technology that can reconstruct the images inside a person’s mind and display them on a computer monitor. That means it won’t be long before you can share your thoughts and dreams with others the way you share your flickr pics. They’ve successfully displayed simple images produced in the human brain on a computer screen.

The device converts electrical signals sent to the visual cortex into images that can be viewed on a computer screen. In the experiment, they showed test subjects the six letters in the word neuron and successfully reconstructed the word on screen by measuring brain activity. So, is this awesome or scary as hell? I vote scary.
