In an astonishing step forward in biomolecular computing, Harvard researchers encoded a 19th century film clip in DNA and stored it inside living bacteria. Later, they sequenced the bacterium's genome and decoded the film. From IEEE Spectrum:
To get a movie into E. coli’s DNA, (neuroscientist Seth) Shipman and his colleagues had to disguise it. They converted the movie’s pixels into DNA’s four-letter code—molecules represented by the letters A,T,G and C—and synthesized that DNA. But instead of generating one long strand of code, they arranged it, along with other genetic elements, into short segments that looked like fragments of viral DNA.
E. coli is naturally programmed by its own DNA to grab errant pieces of viral DNA and store them in its own genome—a way of keeping a chronological record of invaders. So when the researchers introduced the pieces of movie-turned-synthetic DNA—disguised as viral DNA—E. coli’s molecular machinery grabbed them and filed them away.
Remember UC Berkeley researcher Pieter Abbeel’s fantastic towel-folding robot? Now, Abbeel and his team have prototyped a new kind of robot arm design meant for the home and other human environments. Compared to robot arms common in factories, this manipulator, called Blue, is less expensive (
