(Phys.org)—Scientists have built tiny logic machines out of single atoms that operate completely differently than conventional logic devices do. Instead of relying on the binary switching paradigm like that used by transistors ...
Researchers at McMaster University have established a way to harness DNA as the engine of a microscopic "machine" they can turn on to detect trace amounts of substances that range from viruses and bacteria to cocaine and ...
