Relationships of scale cortisol content suggests stress resilience in freshwater fish vulnerable to catch-and-release angling in recreational fisheries

The paper uses scale cortisol content to assess chronic stress in fish subjected to catch-and-release angling, finding that fish most vulnerable to capture have lower cortisol levels, suggesting stress resilience.

The hunt for ancient prions: Archaeal prion-like domains form amyloids and substitute for yeast prion domains

This paper identifies prion-like domains in Archaea that form amyloids and transmit non-Mendelian inheritance, suggesting prions existed in the last universal common ancestor.
