Ear Grown From Van Gogh DNA On Display 64

First time accepted submitter afeeney (719690) writes 'The Centre for Art and Media in Karlsruhe, Germany, is displaying an ear grown from DNA contributed by a relative of artist Vincent Van Gogh. The Center said artist Diemut Strebe made the replica using living cells from Lieuwe van Gogh, the great-great-grandson of Vincent’s brother Theo. Using a 3D-printer, the cells were shaped to resemble the ear that Vincent van Gogh is said to have cut off during a psychotic episode in 1888. “I use science basically like a type of brush, like Vincent used paint,” Strebe told The Associated Press. Historians argue about whether Van Gogh cut off his own ear and if so, why, but it remains one of the most famous acts of self-mutilation in the Western world.'

I mentioned Aho, Hopcroft & Ullman before. Another series of books/lectures to consume to change your brain about what you're doing when you're programming is Donald Knuth's series The Art of Computer Programming. You can start from here: http://cs.stanford.edu/~uno/ta... Go find some of his stuff on YouTube. You will undoubtedly cook your brain a bit, so give yourself plenty of rest between episodes of exposure.

Comment Re:no caffeine in chocolate (Score 2) 283

There are a number of things in chocolate -- and there does appear to be some validity to there being a small amount of caffeine in chocolate, I would ask that you provide specific citations which show that caffeine is the strongest component. It may be the strongest in terms of its stimulant effectiveness, however the quantity of caffeine vs theobromine leaves it in the "also-ran" category in typical batches of chocolate from the reading I've done.

Comment Why is Chocolate even on the list? (Score 2) 283

Chocolate (unless it's been infused/mixed with caffeine bearing extract, coffee beans, or tea) has theobromine which is a close relative of caffeine. Pure chocolate has no caffeine. The kick from theobromine is much lighter and shorter lived than caffeine. Ref: http://www.xocoatl.org/caffeine.htm Let's discontinue the urban legend of caffeine in chocolate. At the same time I'm all for well made mocha that brings the joys of coffee/caffeine together with chocolate/theobromine!

Comment Biogenic vs Abiogenic Petroleum Theories (Score 1) 293

This statement " Even more interesting is that oil or petrochemicals used to create this type of plastic are only known to come from ancient fossilized organic materials, such as zooplankton and algae, which geochemical processes convert into oil pointing to the earthshaking evidence that there was once life on mars." is a bit behind the times. Research in recent times shows that petrochemicals can be generated from crystalline hydrocarbon compounds found in a variety of commonly found subterranean igneous formations. There are in fact people who explore for oil based on this theory of abiotic petroleum generation in place of the old theories that crude oil was only created from organic sources.
