Understanding how a red seaweed reduces methane emissions from cows
Dipti Pitta with cows.

Dipti Pitta and researchers in her lab at the School of Veterinary Medicine are investigating how adding a certain type of red seaweed to a cow's diet can curtail methane emissions, which are one of the top contributors to climate warming.

Four academic journeys explored
Vijay Balasubramanian writes equations on a whiteboard with a graduate student

Younger scientists often ask him about exploring multiple fields, Balasubramanian says. The advice he offers is to “have a central line where you have credibility, where you’ve established that you’re really, really good at what you do, and you can be trusted.”

Kotaro Sasaki and his team unveil the genetics of testicular cancer
Microscopic image of seminoma tissue. The image shows green-stained cells representing early-stage germ cells, red-stained areas indicating high gene activity linked to cancer growth, and gray-stained nuclei of various cells
Section of seminoma tissue, a type of testicular cancer, showing strong expression of proteins/RNAs (TFAP2C, green; BICD1, red) that are typically present in pre-migratory/migratory primordial germ cells, precursors of sperm.

Kotaro Sasaki and his team unveil the genetics of testicular cancer

Researchers from Penn Vet develop the first in vitro seminoma model, shedding light on chromosomal anomalies and signaling pathways.
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.
