Latest OR gate Stories

The circuit is designed to act as the controller in synthetic bacteria that monitor and modify their environment By force of habit we tend to assume computers are made of silicon, but there is actually no necessary connection between the machine and the material. All that an engineer needs to do to make a computer is to find a way to build logic gates — the elementary building blocks of digital computers — in whatever material is handy. So logic gates could theoretically be made of...

Since the idea of using DNA to create faster, smaller, and more powerful computers originated in 1994, scientists have been scrambling to develop successful ways to use genetic code for computation. Now, new research from a professor at Rensselaer Polytechnic Institute suggests that if we want to carry out artificial computations, all we have to do is literally look around.Assistant Professor of Cognitive Science Mark Changizi has begun to develop a technique to turn our eyes and visual...
