Submission + - A 50-terabyte database of brain maps

Roland Piquepaille writes: "If you want to compare images from human brains with the ones of monkeys, dogs, cats, mice or birds, you should visit the BrainMaps.org website at UC Davis. It contains over 50 terabytes of brain image data directly available online. The researchers have found a way to transform sections of brain mounted on microscope slides into brain maps with a resolution of half a micrometer per pixel, or 55,000 dots per inch. With such a resolution, all the images are fully zoomable. You start with a single section of a brain and you explore it like if you had a virtual microscope. And the site also provides free downloadable tools to see the images in 3-D. Be warned: you might spend lots of time exploring this site. Here are more details about this project and pictures showing how the brain navigating process works and what a barn owl's brain looks like."

Submission + - BitTorrent video download store falls flat

seriouslywtf writes: We've all heard about BitTorrent going legit this week with legal movie and TV show downloads. Ars Technica took a look at the service to see how useable it was and ran into a few snags, including not being able to download or even open the video files on some computers. However, the ones that they did manage to open varied a lot in quality. Overall, they blame DRM. From the article:

Without knowing whether browser compatibility and dysfunctional video files are a rare occurrence or not, it's hard to say whether BitTorrent's service is a good one overall. Our initial experiences have been disappointing and frustrating, and guess what the culprit is once again? DRM. Why the DRM failed to work on 50% of our purchases is not clear, but whatever the cause, it's simply unacceptable.

Submission + - How much energy is in a cubic mile of oil?

Prof. Goose writes: "http://www.theoildrum.com/node/2320



A lot's been said lately about how much energy is in a cubic mile of oil. This is roughly the amount the world uses in a year.


(then a really cool graphic showing oil/energy equivalents for other sources)



Leaving aside some errors in these numbers that I found (the coal and nuclear numbers are off by about 10% to each other, and the capacity factor of wind turbines should be closer to 30%) the most essential oversight in that equation is elephantine: It compares oil's inputs to the other's outputs. Compared to that, the rest is small potatoes. Let's discuss it.
