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 ...

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 ...

Take the 2017 PBS Digital Studios Survey: http://surveymonkey.com/r/pbsds2017. Today we’re going to create memory! Using the basic logic gates we discussed in ...

Memory effects are ubiquitous in nature and the class of memory circuit elements – which includes memristors, memcapacitors and meminductors – shows great potential to understand and simulate the ...
