A remotely-controlled robot sent to inspect and clean a damaged reactor at Japan's Fukushima nuclear plant had to be pulled early when its onboard camera went dark, the result of excess radiation. The abbreviated mission suggests that radiation levels inside the reactor are even higher than was reported last week — and that robots are going to have a hell of a time cleaning this mess up.

In a breakthrough that will appeal to both spies and those who work with priceless but frail historical documents, researchers at MIT have developed a camera that uses terahertz radiation to peer at the text on pages of a book, without it having to be open.

How does one read a book without opening it? Why would you want to read a closed book in the first place? While not a common problem, it's enough of one that MIT research scientist Barmak Heshmet decided to have a crack and came up with a system that uses terahertz radiation, femto-photography and air to read characters from a closed book, along with an algorithm that can give CAPTCHAs a run for their money.

Over 100,000 evacuees left in a hurry and left behind a snapshot of what life looked like in the moments just before they fled. A brave soul recently snuck in to photograph the apocalyptic scene today.
