Debut for World's Fastest Camera
from BBC News Online
The fastest imaging system ever devised has been demonstrated by researchers reporting in the journal Nature. Their camera snaps images less than a half a billionth of a second long, capturing over six million of them in a second continuously.
It works by using a fast laser pulse dispersed in space and then stretched in time and detected electronically. The approach will be instrumental in analysing, for example, flowing blood samples in a search for diseased cells.
What is more, the camera works with just one detector, rather than the millions in a typical digital camera. Dubbed Serial Time-Encoded Amplified imaging, or Steam, the technique depends on carefully manipulating so-called "supercontinuum" laser pulses.

PODCAST & VIDEO: 3D Printing Replacement Body Parts
Regenerative medicine, a fledgling field with the aim of regrowing parts from a person’s own cells, is being amplified with 3D-printing technology, which can now use organic materials to create scaffolds that cells need to grow into their final forms. Richard Wysk, a professor of industrial and systems engineering at North Carolina State University, discusses the latest successes with this research, and the timeline for creating more complicated structures.
