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.

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.
Image Cache: Since March 2011, a 50km radius around the ruined Fukushima Daiichi reactor has been a designated exclusion zone, unsafe to travel. 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.

Earlier this week, we heard alarming reports of a "significant" nuclear waste leak at Hanford, the largest radioactive waste dumpsite in the US. Should we be worried? Absolutely. But mainly because this is a symptom of a much bigger problem that's been festering for decades.
