Abstract:	A time frame of X-ray diffraction movie recorded from bumblebee flight muscle recorded at 5,000 frames/s.  From Iwamoto & Yagi, Science, 341, 1243 (2013).
	The very intense X-ray beams from the 3rd-generation synchrotron radiation facilities, in combination with high-speed CMOS video cameras, enable us to record diffraction patterns from moving objects with a sub-millisecond time resolution. By using this technique, we recorded diffraction patterns from the flight muscle of a live bumblebee during wing-beat at a speed of 5,000 frames/s. The diffraction movie reveals the molecular mechanism for the high-frequency wing-beat of insects.
Biographical Sketch:	Hiroyuki Iwamoto is a Senior Scientist at Japan Synchrotron Radiation Research Institute (JASRI), SPring-8, one of the largest synchrotron radiation facilities of the world, and he has been working there since 1997 when SPring-8 came into operation. His main expertise includes biophysics and X-ray diffraction/scattering from non-crystalline materials. His major techniques are X-ray microbeams and high-speed diffraction recordings.
