Some recent technology news stories I had a hand in:
The United States wants to double the pace of research into tackling cancer, and do in the next five years what was shaping up to take ten. Optical imaging will need to play its part, but then so will just about everything everywhere.
Such as: learning more about how oxygen in the blood promotes or chokes tumor growth, an understanding of which is getting better all the time.
Elsewhere: lots of biological materials polarise the light they reflect, so a new lens able to image both left- and right-polarized images at the same time from the same object should make it easier to spot what nature is up to.
