Those circuits depend on enzymes known as recombinases, which can cut out stretches of DNA, flip them, or insert them. Sequential activation of those enzymes allows the circuits to count events ...

Any robot that moves needs actuators—motors that move parts of the robot around. While robot actuators have been around since the dawn of machines, they have some issues. For one, it is very difficult ...

IBM says that it has figured out how to create a bit of memory using just 12 atoms. IBM says that it has figured out how to create a bit of memory using just 12 atoms. IBM Research is detailing its ...

One bit of digital information can now be successfully stored in an individual atom. This result is a breakthrough in the miniaturization of storage media and has the potential to serve as a basis for ...

Engineers have created genetic circuits in bacterial cells that not only perform logic functions, but also remember the results, which are encoded in the cell's DNA and passed on for dozens of ...
