(Nanowerk News) A new graphene-based optical logic gate uses collective oscillations of electrons to process light waves in a far smaller space than existing designs. The device also benefits from low ...

A single logic gate can only do one simple function. To create more complex decisions and control systems, such as how a robot moves or how a microwave starts when the door is closed and a timer is ...

Oscillators, also called astable multivibrators, are electronic devices that generate a periodic signal. They are employed in a large number of applications such as clocks, oscillophones, musical ...

I fear the topic of this column is poised to unleash a tsunami of controversy. My engineering accomplice Joe Farr says that this is one of those topics that, when presented to 10 different engineers, ...

We’ve often said you can make a logic gate out of darn near anything. [The Action Lab] agrees and just released a video showing how he made some logic gates from chains and gears. Along the way, he ...

(Nanowerk News) One of the most exciting developments in cancer treatment is a wave of new cell therapies that train a patient’s immune system to attack cancer cells. Such therapies have saved the ...
