Snow flies now less mysterious but even more fascinating:
"Coordinated molecular and physiological adaptations enable activity at sub-freezing temperatures in the snow fly Chionea alexandriana", Capek et al. (Stensmyr and Gallio labs).
https://www.cell.com/current-biology/fulltext/S0960-9822(26)00247-2How they stay alive, balancing resource expenditure and the need to remain not frozen:
"direct measurements reveal that snow flies produce brief bursts of endogenous heat in response to cooling at sub-freezing temperatures, indicating active thermogenic capacity."
And as always, lots to learn, in this case for medicine:
"our results demonstrate that Chionea has evolved mechanisms to cope with high levels of reactive oxygen species (ROS), a byproduct of mitochondrial activity and a hallmark of cold exposure."
