Although you are fairly unlikely to start zapping your gadgets with high-power lasers any time soon, scientists are already hard at work trying to make electronics immune to such cruelty. In another in a series of self-healing electronics breakthroughs, a team of scientists from the California Institute of Technology (Caltech) demonstrated chips capable of dealing not only with laser-inflicted physical damage but also with far more common ailments such as aging, power fluctuations, changes in temperature or load mismatch.
