  1. 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).

    How 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."

  2. I've just gone down a fascinating rabbit hole (as one does)!

    In The Vengeance of An, a character mentions that someone else habitually chews on bitter herbs, because people in the North do that to stay warm.

    So I looked it up (of course!) and there’s growing evidence that some bitter compounds can stimulate thermogenesis, the process by which your body generates heat and burns calories. This is so cool! 1/n

  3. Through a series of experiments in mice, the team discovered that changing the amount of these amino acids in the animals’ diet produced effects comparable to continuous cold exposure at five degrees Celsius.

  4. Scientists Discover a Diet That Burns Fat Like Cold Exposure, Leading to Significant Weight Loss

    By tweaking just two amino acids in the diet, researchers found a way to mimic the fat-burning effects of cold exposure.

    Their work centered on two amino acids, methionine and cysteine.
