We often hear complaints about what students say and do online, but we often neglect to look into educators helping them manage their online reputation. This infographic is geared toward adults, but it can serve as a great starting point for conversations and activities that educators can engage in with students to help them to establish an active digital footprint that represents who they want to be perceived as online.

If there’s ever excuse to publish an optical illusion as cool as the “Rotating Snakes,” I’ll take it. This illusion was invented in 2003 by Akiyoshi Kitaoka of Ritsumeikan University in Japan, and ever since, Kitaoka and other scientists have been trying to figure out why it works. A new paper by Stephen Macknik at the Barrow Neurological Institute in Phoenix may have the answer. Via Sakis Koukouvis Delete the scoop?

To we who live in the twenty first century, whose lives are enmeshed in various information processors, the eventual plausibility of the Matrix does not appear as radical as it once did. One by one, the photos we view and the mail we send, have been converted to digital form. Common questions, such as, “How many megabytes does that song take up?" reflect a society that is becoming increasingly accepting of the idea that the observable qualities of every object can be represented by bits, and physical processes by how they manipulate these bits. Some scientists have even gone as far as to speculate we could live within a giant information processor, a giant ‘Matrix’, programmed to simulate the laws of physics we know.

Green groups around the world are turning to social networking to drive their campaign for Earth Hour on Saturday, when lights are turned off for an hour to signal concern about global warming.But here's the irony. With every email, every tweet, every appeal watched on YouTube or "liked" on Facebook, environmentalists are stoking the very problem they want to resolve. Each time we network, we emit carbon dioxide (CO2) through the fossil fuels which are burned to power our computers and the servers and databanks that store or relay our message.

If you watch this video normally, the moving circles in the first animation rotate while the shifting dots in the second clip follow a horizontal path. But if you look away and watch the movie out of the corner of your eye, the direction of motion will appear to change. In both cases, the moving objects seem to follow the direction of the background stripes. Via Sakis Koukouvis Delete the scoop?

For most of us, it's tricky enough to remember what we were doing this time last week, let alone on some random day years ago. But for a blind 20-year-old man referred to by researchers as HK, every day of his life since the age of about eleven is recorded in his memory in detail. HK has a rare condition known as hyperthymesia and his is only the second case ever documented in the scientific literature (the first, a woman known as AJ, was reported in 2006.

On an off-grid property in Philo, California (Mendocino County), Loren Amelang built a home that would help him generate "free hot water, free power and a decent chunk of free heat". Putting his technical skills to use (he's a pioneer in C++ programming), Amelang wrote over 10,000 lines of code so that his home's water and electric systems could be operated more efficiently and automatically. An added benefit is the ability to control everything remotely, by even just a smartphone Via Sakis Koukouvis Delete the scoop?
