Nanosecond-scale release of stinging jellyfish nematocysts
By using an electronic ultra-high-speed camera, researchers have characterized the explosive discharge of stinging jellyfish nematocytes and show that this event represents one of the fastest cellular processes in nature. The research is reported by Thomas Holstein of the University of Heidelberg and his colleagues in the May 9th issue of Current Biology. Nematocysts (also known as cnidocy...Just one nanosecond: Clocking events at the nanoscale
MADISON - As scientists and engineers build devices at smaller and smaller scales, grasping the dynamics of how materials behave when they are subjected to electrical signals, sound and other manipulations has proven to be beyond the reach of standard scientific techniques. But now a team of University of Wisconsin-Madison researchers has found a way to time such effects at the nanometer...
