Like modern-day high performance machines, cells are constantly monitoring signals in their environment in order to “decide” on a course of action such as growth or movement. The signals are ...

This handy circuit can be used to charge from one to 12 NiCd cells from a car battery. Up to six cells can be charged with switch S1 in the “normal” position. The LM317regulator operates as a simple ...

Learn how to make a simple lemon battery and use it as an emergency phone charger in this hands-on science experiment. Watch ...

In new research, Alex Green, an assistant professor at ASU’s Biodesign Institute, demonstrates how living cells can be induced to carry out computations in the manner of tiny robots or computers. The ...

Electronic gizmos and living cells alike can process signals, turning inputs into outputs—even recognizing when gray-area signaling is dark enough, or light enough, to justify decisions that are, well ...

In this project, we design a Cell Phone or Mobile Phone Jammer Circuit. This circuit can be used in TV transmission and also for remote controlled toys or play things. In this project, we design a ...

Cells in nature have to respond to environmental stimuli with a complex repertoire of responses. In effect, they make computations that require processing that is both analog, like adjusting to a ...

Genetic circuits control the activity of genes and thereby the function of cells and organisms. Scientists have shown how various genetic circuits in bacterial cells are influenced by growth ...

Encapsulating molecular components in artificial membranes offers more flexibility in designing circuits, report researchers. Synthetic biology allows scientists to design genetic circuits that can be ...

Complex brain circuits in rodents can organize themselves with genetics playing only a secondary role, according to a new computer modelling study published today in eLife. The findings help answer a ...
