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.

VIDEO: How Hair Ice Grows
In 2013, American Scientist featured an article on odd ice formations on plant stems, including these curling ribbons of ice. One of the types of ice discussed in the article was hair ice—long, thin strands of ice that grow under quite specific conditions. The only problem is that a new study shows the theory put forth at the time—that gas pressure pushes the water out—isn’t correct... (click the link above to read more).
