A test-tube circuit made of DNA-based logic gates can calculate the square root of numbers up to 15, using DNA replication and sequence binding to conduct computations. It's excruciatingly slow ...

Horrible Science fact It's all well and good having a perfect, simple circuit but it it includes a switch, it will only work if the switch is in the on position meaning the circuit is closed. You ...

Engineers have designed cells that can count and "remember" cellular events, using simple circuits in which a series of genes are activated in a specific order.

Researchers recently tackled a simple circuit in the visual processing area of a chicken's brain that detects motion in its field of view -- with surprising results.

So the results show that they are capable of calculating the lactate threshold within the established limits with 89 percent accuracy, all by using a relatively simple model.

Using DNA as a scaffold, researchers have devised a simple way of creating carbon nanotube transistors—a feat that paves the way for more complex circuits made from these nanomaterials.
