1.5 nanometers: that's how small these letters are -- half a nanometer shorter than those inscribed by inferior brains back in October. Physicists at Stanford achieved the record (which ties Hitachi's work from 1991) by manipulating individual carbon monoxide molecules on a copper surface and then exciting the copper to bounce a holographic pattern off the CO. Software ensures that the molecules are positioned correctly to scatter electron waves into particular shapes, in this case an "S" and "U," before finishing with a "CK IT CAL," presumably. The work could ultimately lead to densely packed storage devices... or not. Just saying.
