How deadly parasites choose to be male
Transcription atlas of Cryptosporidium life cycle.

Penn Vet researchers developed the Cryptosporidium single-cell atlas, revealing which genes are expressed at which points across the parasite’s life cycle. On the left, the atlas shows parasites replicating asexually in green, with males in blue and females in pink. On the right, micrographs of the stages are shown, with their nuclei highlighted in green.
