  • Getting a tighter grip on cell division

    ... even as it disassembles away. At 100 nanometers across, the kinetochore is a true behemoth. One of the most complicated functional molecules in the cell is a ribosome, but that only measures 25 ...
  • Small change makes a big difference for ion channels

    ... classes, with very similar structure but different function: One mediates inhibition by channeling anions, or negatively ... to measure binding and unbinding of single protons in functioning molecules, something that other powerful approaches cannot ...
  • An advance toward ultra-portable electronic devices

    ... write that the "key to single-molecule electronics is connecting functional molecules to each other using conductive nanowires ... positions, and how to ensure chemical bonding between the nanowires and functional molecules." That challenge has stymied many researchers, who have struggled ...
