Controlling gene activity is important for engineering plants for improved bioenergy crops and other applications. This research developed synthetic genes that use Boolean logic gates to achieve ...

When the physicist Richard Feynman died in 1988, he left a note on his blackboard that read, “What I cannot create, I do not understand.” Feynman may have been reflecting on the nature of scientific ...

Over the past 20 years, synthetic biologists have been trying to build biological circuits in living cells to enact specific behaviors such as Boolean logic gates, signal filters, oscillators, state ...

Consider the logic circuit in the figure shown. Determine the Boolean expression at the circuit output and simplify it. From the simplified Boolean expression, find which logic gate is redundant in ...

Targeted drug delivery has long been a cornerstone goal of modern medicine—sending therapies exactly where they’re needed while sparing healthy tissues. Yet creating treatments that can decide when ...

In previous installments, we examined the different types of logic gates in detail, exploring their theoretical and practical applications. In this next part, we will dive into the practice of ...

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, ...

Controlling the activity of genes is an important step in engineering plants for improved bioenergy crops. This research developed synthetic genes that can be combined to achieve specific patterns of ...
