DNA logic gates calculate square root using 130 different molecules A DNA-based computer uses simple base-pairing to create AND and OR logic gates … ...

The new logic gates are formed from short strands of DNA and their complementary strands, which in conjunction with some simple molecular machinery mimic their electronic equivalent.

Importantly, the new biological logic gates are also modular, meaning they could be fitted together to make different types of logic gates and more complex biological processors.

He also had some impractical logic gates that were very illustrative, even if they didn’t work very well. The first attempt fell somewhat short, but all problems were eventually resolved.

One of the "YES" gates they designed is a short peptide -- one of the constituent parts of cellular proteins. This peptide gate can be cleaved by an enzyme known as matrix metalloprotease (MMP).

Logic gates through lasers Using this augmented control landscape, the team was able to experimentally demonstrate, for the first time, logic gates that operate on a femtosecond timescale.

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 ...

It’s time to do a series on logic including things such as programmable logic, state machines, and the lesser known demons such as switching hazards. It is best to start at the beginning &#82… ...

Researchers have now developed the fastest logic gates ever created, by zapping graphene and gold with laser pulses. The new logic gates are a million times faster than those in existing computers ...

For the past several years, researchers have been creating living logic gates, using the genetic on and off switches we've discovered in the biochemical world to create simple logical functions ...
