A camera that can see around corners
Why is this relevant to you? Well think of it this way, if we can make a camera with a 1 trillionth shutter speed, the ISO would have to be equally comparable or there would be almost no light visible on the sensor.
Aside from the fact that the linked article is a puff piece of little content, it doesn't follow that just because you can see a pulse of less than 1 trillionth of a second you have all that sensitive of a detector. Try this: a pulse of 1 microjoule and one ten-trillionth of a second has what sort of peak power? One watt = 1 joule/second.
(back when I was a grad student we'd generate pulses of white light by focusing a femtosecond pulse into plain water. The water didn't absorb at that wavelength, but the field strengths were so high it didn't matter. Look up "continuum generation".)
