With the nuclear reactor incident in Fukashima, Japan making headlines world-wide, do you know exactly how much radiation is bad?

Randall Munroe of XKCD created what is probably the most informative chart about the different doses of radiation you get from various activities of life, from sleeping next to someone to flying over the USA to getting a chest X-ray and more.

Check out the chart here.

How Nuclear Power Plants Work

Maggie Koerth-Baker at Boing Boing wrote an excellent piece on how nuclear power plants work. With the devestation of the earthquake and tsunami in Japan and the Japan nuclear power plan situation, this is a great read to get up to speed on the basics of a nuclear power plant.

For the vast majority of people, nuclear power is a black box technology. Radioactive stuff goes in. Electricity (and nuclear waste) comes out. Somewhere in there, we’re aware that explosions and meltdowns can happen. Ninety-nine percent of the time, that set of information is enough to get by on. But, then, an emergency like this happens and, suddenly, keeping up-to-date on the news feels like you’ve walked in on the middle of a movie. Nobody pauses to catch you up on all the stuff you missed.

As I write this, it’s still not clear how bad, or how big, the problems at the Fukushima Daiichi power plant will be. I don’t know enough to speculate on that. I’m not sure anyone does. But I can give you a clearer picture of what’s inside the black box. That way, whatever happens at Fukushima, you’ll understand why it’s happening, and what it means.


Saturn fly-by video

Created from thousands of high-resolution photographs taken by the Cassini orbiter, there is no 3D CGI involved in this video. There’s a black and white version first, followed by a full-frame, full-color video beginning around the 1:00 mark.

Permanent anti-fog coating discovered

Researchers from Quebec City‘s Université Laval have developed what they claim is the world’s first permanent anti-fog coating. Just one application is said to work indefinitely on eyeglasses, windshields, camera lenses, or any other transparent glass or plastic surface. So very soon you may not need to worry about your glasses, prescription or otherwise, fogging up.
