The Turing Test was not passed!

Last weekend’s news in the tech world was flooded with a “story” about how a “chatbot” passed the Turing Test for “the first time”: Many media outlets were reporting that a computer programme pretending to be a 13-year-old boy from the Ukraine passed the Turing test for artificial intelligence on Saturday. The problem is that

Friday Fun: Scientists explain their processes

Scientists explain their processes with a little too much honesty and Scientists explain their processes with a little too much honesty [17 pictures] articles show a series of pictures that might find funny. Back in January, scientists started making “secret” confessions on Twitter and some some kind soul combined a few of these Tweets with

Do LEDs cause blindness?

Do LEDs cause blindness? article tells that According to a study led by Dr. Celia Sánchez-Ramos, of Complutense University in Madrid, prolonged and continuous exposure to LED light might be sufficient to damage the retina. Her study, published in the journal Photochemistry and Photobiology in 2012 found that LED radiation caused significant damage to human

Wifi gesture control

Gesture control uses WiFi doppler shift article tells that researchers at University of Washington have built a WiFi-based gesture control system. The system uses doppler shift in Wifi signal combined with Software-Define Radio (SDR) to detect humans moving near the devices. The researchers see WiSee as a novel interaction interface that leverages ongoing wireless transmissions

Lights and brain cells

Researchers have long been trying to discover the mysteries of the brain, as well as target areas within to control behaviors. Optogenetics might be a relatively unknown area of neuroscience. Researchers inject tiny LEDs into the brain to control behavior article tells that for almost 15 years, scientists have been experimenting with optogenetics, a new

Capturing "light in flight"

Are you interested in seeing how light propagates? Filming light reflecting off objects article tells about a method for capturing “light in flight”. Making videos of light passing through and around objects has been done before, but this system is much cheaper (few hundred dollars) than those earlier systems ($300,000).
