A neat way to fold a sheet of paper
news.ycombinator.com (8) http://wheatpond.com/2012/02/22/miuraori.htmlThe Miura-ori is a method for folding up a sheet such that it can be opened or closed in one smooth motion. A Miura sheet has only one degree of freedom, and can be thought of as having only two states: fully open, or fully closed. Since reversing one fold in the sheet (that is, making a “mountain” into a “valley”) requires reversing all of the adjacent folds as well, the Miura sheet feels as though it has a memory, and is very resistant to def
Biologists Debunk the "Rotting Y Chromosome" Theory

However, researchers of a study published in the latest issue of Nature found evidence to suggest that the Y chromosome will not shed anymore of the 19 ancestral genes that it
Hack your way through Stripe's Capture the Flag

Microsoft's Anti-Google Video Campaign

Intel becomes a foundry, offers up its 22nm process

Faulty Cable To Blame For Superluminal Neutrino Results
slashdot.org (190) http://science.slashdot.org/story/11/09/22/1841217/cern-experiment-indicates-faster-than-light-neutrinos?sdsrc=rel"It would appear that the hotly debated faster-than-light neutrino observation at CERN is the result of a fault in the connection between a GPS unit and a computer . This connection was used to correct for time delays in the neutrino flight, and after fixing the correction the researchers have found that the time discrepancy appears to have vanished."
Faster-than-light neutrino result may have been due to bad connection

A bad connection between a GPS unit and a computer may be to blame. Physicists had detected neutrinos travelling from the CERN laboratory in Geneva to the Gran Sasso laboratory near L'Aquila that appeared to make the trip in about 60 nanoseconds less than light speed

The myth of the eight-hour sleep
