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). Light-in-Flight Imaging page on that

Google’s Self Driving Car Sensor Data

I wrote about Car Electronics at 2012 and updated the article with many comments. Now here is some new news to car electronics technologies that is worth a new post. Google has already logged an impressive amount of miles in its Toyota Prius fleet equipped with $70,000 radar systems. Google’s Self Driving Car Gathers Nearly

A Boy And His Atom

What can you make out of few atoms? This Stop Motion Movie Is Animated Using Individual Atoms article tells that researchers at IBM take a break from exploring the limits of data storage at the molecular level—and instead make stop motion films, animated entirely with individual atoms. This is the result: A Boy And His

Visualizing 100,000 Stars In Chrome

Google has rolled out a new web experiment for Chrome. 100,000 Stars: Google’s latest Chrome experiment taps NASA to visually explore the Milky Way. This one is a visualization of the locations of over 100,000 nearby stars (pulls data from astrometric databases and catalogs). Using Chrome’s WebGL, CSS3D, and Web Audio support, you can zoom

LED is 50 years old

The LED As We Know It Is 50 Years Old Today. In 1962, 50 years ago today, Nick Holonyak Jr. and his team at GE invented the Light Emitting Diode. While LED lights are almost everywhere today, their initial development was ripe with uncertainty and competitive research. A direct result of another groundbreaking technology of

Avaruusrekka (space truck)

I saw Avaruusrekka when driving by it in Espoo. I had to stop and see briefly what was going on. Avaruusrekka is a space exhibition on wheel that is moving around Finland just now (stops at eight locations from 3 to 17. October 2012). Next stops are in Helsinki and on weekend the truck is
