The digital world offers many advantages over its analog relatives, the use of boolean logic among them. Some of the functions, like NOT, OR, and AND are fairly straightforward and line up nicely with ...

A team of UCSF researchers has engineered E. coli with the key molecular circuitry that will enable genetic engineers to program cells to communicate and perform computations. The work builds into ...

Logic gates are the bricks and mortar of digital electronics, implementing a logical operation on one or more binary inputs to produce a single output. These operations are what make all computations ...

The Boolean logic gates AND, OR and NOT comprise transistors, which are on/off switches wired together. Gates have one or two inputs but only one output, and they are wired in patterns that make up ...

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 ...

Scientists have announced that they have built and tested a new biomaterial-based delivery system -- known as a hydrogel -- that will encase a desired cargo and dissolve to release its freight only ...
