Brightfield image of transgenic C. elegans expressing a cytoplasmic red fluorescent protein under the control of the promoter for the unc-129 gene. This means that the protein only comes about in the DA and DB motor neurons, which have cell bodies on the ventral side of the animal and synapses on the dorsal side, so their axons must cross the width of the animal.
Brightfield image of Plectus sambesii, a nematode I'm trying to establish as a model for behavioral and cell type-evolution in the laboratory. It's about half a billion years divergent from the more common C. elegans. This image shows a 'bagged' mutant(?) adult with multiple developing embryos stuck inside. Normally, adults carry 1-2 eggs at once. This one has 4-6.
Unedited picture of Columbia's campus I took in the fall of 2024. It doesn't normally look this nice.
