Computers use transistor-based logic gates as the basis of their functions, but molecular logic gates would make them much faster. A report of DNA-based logic gates could be a first step towards ...

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 ...

Researchers have reverse-engineered a cellular signal processing system and used it like a logic gate -- a simple computer -- to better understand what causes specific cells to migrate.

The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is ...

Others are more elusive, like XOR and NAND. For those just getting their start in digital logic, this teaching tool allows different logic gates to be wired together with patch cables.

Last year, however, researchers showed that phase change memory could also be used to create logic gates, the basic functional units of a modern computer.

Scientists at the University of Sydney have for the first time demonstrated improvement in quantum computers by using codes designed to detect and discard errors in the logic gates of such machines.

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 ...
