How to make a fish face, and other photo contest winners
Winning imaging technique allows geneticists to study development at cellular level
This forlorn-looking face of a 4-day-old zebrafish embryo represents “a whole new avenue of research” for geneticist Oscar Ruiz, who studies how faces and facial abnormalities develop at the cellular level.
The research is possible thanks to a new method, developed by Ruiz and colleagues at the University of Texas MD Anderson Cancer Center in Houston, for mounting embryos in a gel that allows for clear, head-on pictures. A technique called confocal microscopy captures images like the one above, the first-place winner of this year’s Nikon Small World photography contest.
