Light-based logic: The optical chirality logic gate is made of a nonlinear optical material that generates an output signal that’s dependent on the chirality of the two input beams. (Courtesy: Yi ...

A small field within synthetic biology is working to make simple and reliable logic gates within living cells to act as versatile control elements, streamlined and digital alternatives to the ...

Now scientists from Imperial College London have demonstrated that DNA (and bacteria) can be used to create the fundamental building blocks of a computer - logic gates. Using DNA and harmless gut ...

DNA-based nanotechnology has been around for more than 30 years, but it really took off in 2006, when DNA origami was featured on the cover of Nature ... Various logic gates—AND, OR, XOR ...

DNA-based logic gates that could carry out calculations inside the body have been constructed for the first time. The work brings the prospect of injectable biocomputers programmed to target disea ...

The basics of digital logic are pretty easy to master, and figuring out how the ones and zeroes flow through various kinds of gates is often an interesting exercise. Taking things down a level and ...

A study on logic gates titled "Light-field control of real and virtual charge carriers" has been published in the journal Nature. Researchers have developed a new kind of logic gate, the ...

A chip that contains one logic gate or a small number of logic gates. Although thousands of gates are routinely placed on a single chip, discrete logic chips with only one or two gates are also ...
