The ability for cells to control gene expression in response to changing conditions is crucial for their survival. People spend their entire careers teasing apart these mechanisms, many of which are ...

A solid knowledge of logic gates is at the basis of programming and electronics. This is required in any project. Truth tables are a great way to visualize the results of various combinations of ...

A hybrid computer uses rotating mechanical beams for memory and electrical contacts for logic, performing reprogrammable computation through physical motion in environments where conventional ...

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 ...

A logic gate is an electronic component (or set of them) that performs a logic operation, in which the binary values 0 and 1 are represented with two different voltage values, as seen in the previous ...

Logic gates are the fundamental building blocks of computers, and researchers at the University of Rochester have now developed the fastest ones ever created. By zapping graphene and gold with laser ...

I wonder if this is the right forum to ask this question in.<BR><BR>Anyways, today in class we went over logic gates: AND, OR, XOR, and NOT. Now, I can remember AND and NOT but not OR and XOR. AND is ...
