| 2010-03-08 | IBM brings on-chip optical comms closer to reality IBM scientists took a step forward in replacing electrical signals that communicate via copper wires between computer chips with tiny silicon circuits that communicate using pulses of light. |
| 2007-09-03 | Electronics zero in on cancer cells Researchers have invented an inexpensive, minimally invasive surgical technique that makes use of irreversible electroporation to kill cancer cells with short electrical pulses. |
| 2007-04-18 | Quick start for beginners to drive a stepper motor A stepper motor is an electrically powered motor that creates rotation from electrical current driven into the motor. Physically, stepper motors can be large but are often small enough to be driven by current on the order of milliampere. Current pulses are applied to the motor, and this generates discrete rotation of the motor shaft. |
