Dananajaya Ramanayake sends along this excerpt from Wired: "Nearly 62 years after researchers at Bell Labs demonstrated the first functional transistor, scientists say they have made another major breakthrough. Researchers showed the first functional transistor made from a single molecule. The transistor, which has a benzene molecule attached to gold contacts, could behave just like a silicon transistor. The molecule's different energy states can be manipulated by varying the voltage applied to it through the contacts. And by manipulating the energy states, researchers were able to control the current passing through it."
