Out today in Nature: We uncover a neural mechanism for the integration of two internal states - hunger and estrous state - and how this integration shapes pup-directed behaviors in mice.

Integration of hunger and hormonal state gates infant-directed aggression - Nature
Combined behavioural, circuit-level and cellular approaches are used to demonstrate how hypothalamic neurons integrate hunger and oestrous state to drive a switch in how female mice interact with pups...

I am thrilled to share our latest work: we identified a population of central amygdala neurons that promote the earliest and perhaps most important social behavior: pup suckling!... We also developed new tools for pup neuroscience
Work by @Jeff Moore now at USC, a collaboration with @Sam Pfaff lab

Federal workers are speaking out on how the Trump regime is harming Americans:
"We stand here today at a moment of the greatest assault of our lifetimes on our freedoms. The US Constitution is being shredded... We are here to call on Congress to stand up and stop it."

New preprint + thread 🧵
#Psychedelics induce the formation of new synapses, but where do they connect?
Our rabies tracing study reveals that #psilocybin shifts connectivity across specific cortical networks.

Sex or survival—what’s more important? Excited to share our
@Nature paper on how flies resolve this conflict.
We found a dopamine-based filter that reduces threat perception, helping flies focus on courtship when close to mating.
