Light helps us wake up, keeps us alert, and guides our sleep. But what happens when light becomes erratic? As a researcher studying molecular biology and animal stress responses, I've been fascinated by how environmental ...
Inside cells, two important enzymes act like small central regulatory hubs: dipeptidyl peptidase 8 and 9—DPP8/9 for short. Among other things, they regulate inflammatory reactions and influence whether a cell survives or ...
