“But now I can take a speck of nothing and park it next to a nerve or organ, your [gastro-intestinal] tract or a muscle, and read out the data.” Ultrasound vibrations, which can penetrate almost every part of the body, are used to power the sensors, which are about a millimetre across.They contain a special crystal that converts ultrasound into electricity to power a tiny transistor.A tiny implant the size of a grain of sand has been created that can connect computers to the human body without the need for wires or batteries, opening up a host of futuristic possibilities.

Working with rat neurons grown in a petri dish in the laboratory, the team artificially connected two neurons using an atomic force microscope and tiny, polystyrene spheres.However, that 18,000-year-old date was based on only a geological analysis of the fossils' surroundings and not on direct analysis of the bones themselves.And the complexity of the cave's geology initially misled the scientists, says Matthew Tocheri, a paleoanthropologist at Lakehead University in Thunder Bay, Ontario, Canada, and a member of the discovery team.Now, many of the same scientists who made the discovery have radically revised their estimate of the fossils' age, based on an exhaustive new analysis of the cave’s geology.Instead of living 18,000 years ago, as they originally reported, the hobbit lived between 60,000 and 100,000 years ago—some 10,000 years before makes it “impossible to argue that it is a pathologically-dwarfed modern human,” says Russell Ciochon, a paleoanthropologist at the University of Iowa in Iowa City who was not involved in the study.
