New lab paper drop, this one has been a long time coming! Driven by Rob Aukema (now a postdoc with Kerry Ressler) this paper in Science Advances answered the lingering question of what role the amygdala plays in stress-induced neuroendocrine responses.

A network of basolateral amygdala projection neurons contributes to stress-induced activation of the hypothalamic-pituitary-adrenal axis
A network of basolateral amygdala neurons, but not singular projections, contributes to the neuroendocrine response to stress.

Anxiety might not be just in your head, it could be in your gut.
Dr. Sabine Hazan explains how gut bugs from an anxious donor can transfer that anxiety through fecal transplant.

So happy to announce our new preprint, “A geothermal amoeba sets a new upper temperature limit for eukaryotes.” We cultured a novel amoeba from Lassen Volcanic NP (CA, USA) that divides at 63°C (145°F) 🔥 - a new record for euk growth!
