Essentially, it allows precise manipulation of minuscule fluid volumes down to one trillionth of a liter or less to carry out multiple laboratory functions, such as sample purification, running of chemical and biological reactions, and analytical measurement.» (sciencedaily.com)
Applying an electric field to soap films creates controllable swirling patterns, a technique that could make precise manipulation of liquids easier (newscientist.com)
In humans, handedness goes along with the specialization of one side of the brain for precise manipulation, an asymmetry Hunt hopes to look for in crow brains. (sciencemag.org)
