"From a snake embryo with love" by Grigorii Timin, University of Geneva by SNSF Scientific Image Competition Via Flickr: Entry in category 1. Object of study; Copyright CC-BY-NC-ND: Grigorii Timin Development is generally described phenomenologically by the corresponding dynamics of gene expression and the observed morphological changes. Another approach, combining biological and physical processes, consists in the quantitative assessment of the time evolution of 3D spatial distributions of cell differentiation, proliferation, migration and signalling as well as the mechanical properties of the corresponding tissues. Implementation of these parameters in numerical simulations allows identifying their relative importance in the morphogenetic process. My PhD research, under the supervision of Pr. Michel Milinkovitch at the University of Geneva, includes such a multidisciplinary analysis applied to the development of skin scales in snakes. The image is a single focal plane from a 3D confocal scan of a cleared whole-mount African house snake embryonic skin sample stained for proliferating cells (red), beta-catenin (magenta), nuclear envelope lamin (cyan) and nuclei (green).

My favorite place to be. A dark room, isolated from the rest of the world, the microscope humming away as it scans the blackness. So much potential for something to come into being; it’s electrifying.
And when I am the first person to ever witness something in that room, I imagine that the feeling of solitary joy and awe that washes over me must be similar to what astronauts feel when they look back on the earth from thousands of miles away. A moment of breathtaking amazement, alone in my little room of blackness, and the feeling that our understanding of life is but a tiny blip in the greater cosmos of what actually is.
It doesn’t happen often, but when it does, it’s one of the single greatest motivations for me to keep going. To keep shining my little light into the darkness of the unknown, experiencing all of the failures and heartaches that dominate my profession, patiently searching for another sliver of truth. -Q

Colour through the Eye of a Mantis Shrimp by ZEISS Microscopy Via Flickr: The retina and underlying optic lobes of a mantis shrimp have been stained to reveal the many different units of light information processing before it reaches the central brain.

"Confocal immunofluorescence image of intestinal organoid" by Denise Serra, University of Basel by SNSF Scientific Image Competition Via Flickr: Entry in category 1. Object of study; © CC-BY-NC-ND: Denise Serra This image shows immuno-staining of mature intestinal organoids, complex 3-D structures that resemble both morphologically and functionally the intestinal epithelium. Intestinal organoids are great model system to study how the epithelium develops, regenerates after injury and maintain its physiological state. The image has been taken with a confocal microscope, in blue are nuclei (DAPI), in red a membrane protein and in green a transcription factor.
