Scientists at Argonne National Laboratory have coaxed hundreds of these one-celled beasts to turn tiny gears 1 million times heavier than themselves in an experiment researchers hope is a step toward creating new materials and devices that mix tiny chemical cocktails and better harvest and store energy. “Biological systems are extremely efficient,” says Igor Aronson, a physicist at Argonne National Laboratory. “We can learn from biology and we can use it.”...
