Manipulating tiny objects like single cells or nanosized beads often requires relatively large, unwieldy equipment, but now a system that uses sound as a tiny tweezers can be small enough to place on a chip, according to Penn State engineers.


Word of the Day
begunk
  • To befool; deceive; balk; jilt.
  • An illusion; a trick; a cheat.
The word 'begunk' may come from a nasalised variant of Scots begeck ("to deceive, disappoint"), equivalent to be- +‎ geck.
