The Boolean logic gates AND, OR and NOT comprise transistors, which are on/off switches wired together. Gates have one or two inputs but only one output, and they are wired in patterns that make up ...

(Nanowerk Spotlight) Logic gates, especially Boolean logic gates, are the fundamental building blocks of today's computers built with silicon-based circuitry; without them, digital information could ...

Bioengineers have taken computing beyond mechanics and electronics into the living realm of biology. Scientists have used a biological transistor made from genetic material -- DNA and RNA -- in place ...

Researchers from McMaster University and the University of Pittsburgh have created the first functionally complete logic gate ...

Researchers have engineered E. coli with the key molecular circuitry that will enable genetic engineers to program cells to communicate and perform computations. A team of UCSF researchers has ...

A Boolean Algebra operation can be related with an electronic circuit in which the inputs and outputs corresponds to the statements of Boolean algebra. Though these circuits may be complicated, they ...

Finally, E. coli is good for something other than making you regret not washing that lettuce better. Boffins at the Imperial College London have employed the bacteria as living Boolean logic ...

Biological systems have caught the attention of computer scientists, who have been turning everything from RNA molecules to entire bacterial colonies into logic gates. So far, however, these systems ...

Scientists have developed lots of techniques for targeted drug delivery—directly to tumors, for example—to optimize therapeutic efficacy while minimizing side effects. But a new system may be the most ...
