1.   Berger and his colleagues study the way biology has created its circuits using slices of rat hippocampus that can be kept alive in nutrients for a day or more.

2.   Koza and his colleagues have been creating electrical circuits using evolutionary computing.

3.   The blocks, which are battery powered, are joined to create circuits, but the circuits quickly become complicated.

4.   The circuits are created by superheated gases called plasmas that either etch or deposit material on the silicon wafers.

5.   The software searches out the functional switches and wires, bypassing the defective ones, until a complete circuit is created.

6.   While one fifth-grade class creates electric circuits to light a bulb, another investigates crayfish.

7.   The idea to harness the self-assembling abilities of tiny DNA molecules to create electronic circuits was the result of ongoing conversations between the three Technion colleagues.

8.   The alterations would likely create a circuit with more competitive racing by sacrificing the top speeds achieved under existing rules.

9.   The new circuit was created by Indianapolis Motor Speedway owner Tony George to rival the Indy-car series.
