Technology Review has a short article on what has been learned since the meltdowns last year – What We Learned About Nuclear Safety From Fukushima: Reactors and radioactive materials at Fukushima Daiichi were destabilized by back-to-back beyond design-basis events. First was the magnitude 9.0 earthquake that felled the plant’s power lines, triggering diesel generators to […] Well, maybe not all that soon – they’re predicting 10-20 years, which would fit nicely with our timeline for In the Shadow of Ares: Scientists Prepare Test-Tube Burger Starting with bovine stem cells, the Dutch researchers have grown muscle fibres up to 3cm long and 0.5mm thick. The fibres are tethered and exercised as […] This could certainly be useful in martian and lunar settlements, and perhaps moreso on the way to and from them – Researchers successfully treat previously lethal doses of radiation: “The fact that this treatment can be administered up to a day after radiation exposure is so important,” said Millie Donlon, DARPA’s program manager for this […] DARPA will be launching a test flight of the Falcon HTV-2 hypersonic vehicle: If all goes to plan, engineers will launch the Falcon HTV-2 to the edge of space, before detaching the plane and guiding it on a hypersonic flight that will reach speeds of 13,000mph (about 20 times the speed of sound) on its […] The design of the Fukushima reactors (currently experiencing some…er…problems due to the combined effects of the earthquake and tsunami) is detailed in this helpful backgrounder from the NRC: Boiling Water Reactor (BWR) Systems [pdf] I knew a good bit of the science of what went on inside the different types of nuclear reactors, but this […] An interesting project at the South Pole, involving agriculture in a controlled (and in this case, sunless and soil-less) environment: To the moon…South Pole greenhouse model for growing freshies on other worlds Crops of lettuce, kale, cucumber, peppers, herbs, tomatoes, cantaloupes and edible flowers comprise many of the plants grown in the climate-controlled chamber. Because […] High-speed video of droplets of liquid nitrogen rolling across a hot surface, demonstrating something we’ve all seen while cooking but probably didn’t know had a name — the Leidenfrost Effect: From Wikipedia: The effect can be seen as drops of water are sprinkled into a pan at various times while it is heating up.
