Princeton researchers have demonstrated a new way of making controllable “quantum wires” in the presence of a magnetic field, according to a study published in Nature. Continue reading “Controllable electron flow in quantum wires”
In a scientific first, Columbia neuroengineers have created a system that translates thought into intelligible, recognizable speech. By monitoring someone’s brain activity, the technology can reconstruct the words a person hears with unprecedented clarity. Continue reading “Engineers translate brain signals directly into speech”
In Hellenistic and Roman times, the prevailing view was still the geocentric one.
