A device about the size of a dime can manipulate living materials such as blood cells and entire small organisms, using sound waves, according to a team of bioengineers and biochemists from Penn State.


Word of the Day
ecotone
  • A transitional zone between two communities containing the characteristic species of each.
The word 'ecotone' comes 'eco-' plus a Greek root meaning 'tension'.
