Bacterial Genes Make A Complex Logic Circuit
2012-10-13 11:27:12

The circuit is designed to act as the controller in synthetic bacteria that monitor and modify their environment By force of habit we tend to assume computers are made of silicon, but there is actually no necessary connection between the machine and the material. All that an engineer needs to do to make a computer is to find a way to build logic gates – the elementary building blocks of digital computers – in whatever material is handy. So logic gates could theoretically be...

Researchers Create Most Complex Synthetic Circuit Ever
2012-10-09 14:29:55

Lee Rannals for redOrbit.com — Your Universe Online MIT researchers have developed circuit components that can produce the most complex synthetic circuit ever built. The circuit, which was reported in the journal Nature, integrates four sensors for different molecules, and can be used in cells to precisely monitor their environment and respond appropriately. The team had previously designed bacteria that could respond to light and capture photographic images, and others that...

SAN FRANCISCO -- The notorious E. coli bug made its film debut Wednesday. That's when researchers at the University of California, San Francisco and the University of Texas announced in the journal Nature that they had created photographs of themselves by programming the bacteria - best known for outbreaks of food poisoning - to make pictures in much the same way Kodak film produces images. It's the latest advance in "synthetic biology," a disputed research movement launched largely by...


Word of the Day
caparison
  • A cloth or covering, more or less ornamented, laid over the saddle or furniture of a horse, especially of a sumpter-horse or horse of state.
  • Clothing, especially sumptuous clothing; equipment; outfit.
