It should be said too that in the two-state solution scenario, this would still happen because apartheid with all its anti-miscegenation tendencies would still be baked in

Addressing government requirements for "male" and "female" defnitions for athletics and on-campus housing, as well as limits on gender-affirming care As we have for decades, Brown has agreed to abide by Title IX and NCAA eligibility rules regarding the participation of transgender athletes in intercollegiate sports. We also committed that the University will continue to provide housing and restroom access in a way that allows for gender- inclusive, women-only and men-only options. The agreement also states, The University will not perform gender reassignment surgery or prescribe puberty blockers or hormones to any minor child for the purpose of aligning the child's appearance with an identity that differs from his or her sex."' The University will refer affected students who seek care from Student Health Services or the University Pharmacy to area specialists. The agreement does not affect medical teaching or training, and does not apply to clinical services provided by health systems that are separate entities from Brown, such as Brown University Health and Care New England. We remain fully commited to serving the health needs of all Brown students in a manner consistent with our long- established policy of nondiscrimination, which includes sex, gender identity and gender expression.

Brown University is caving to Trump.

They are banning trans women from female bathrooms, dorms, locker rooms, and sports across campus. They're also cracking down on trans care for minors, though that is unlikely to be broadly impactful since it's a university.

While our analyses only focused on neurons, we also collected and sequenced non-neuronal cell types. If you’re interested in these cell types or if you’d like to analyze the neurons from scratch, feel free to dive into the raw data: www.ncbi.nlm.nih.gov/geo/query/ac...

Ever wondered how fasting and lactation affect gene expression in the hypothalamus? Looking for a dataset to mine? Look no further! We performed single-cell RNA sequencing of the arcuate nucleus and medial preoptic area in 4 groups of female mice: zenodo.org/records/1531...

Thanks Giacomo!!!

This is probably my favorite comment from a reviewer. Sometimes, less is more 😉

Thanks Cate! You guys are next! 😄

Thank you! Miss you and the rest of the Correa lab!

Really cool work! I actually presented the preprint at journal club the day before it came out in Nature 😅

🚨Very happy that my PhD work is now out in @nature.com!

We discovered that evolution, by acting in the midbrain, shifted the threshold to escape in Peromyscus mice, to fine-tune defensive strategies in different environments

Thanks Ramón for not only running experiments but also providing your expert advice on BRS3 neurons. Not a tiny contribution!

Thank you! 😊

Thank you Tom!

Thanks so much! 🤗

Great question! Unfortunately we did not look at pup sex. Our assays consisted of 5 pups with likely mixed sexes, and moms are very good at retrieving all of them even if they’re hungry, although we don’t know if male or female pups are more likely to get retrieved first.

Last, stimulating AgRP neurons dampens the basal activity of BRS3 neurons, making them less responsive to pups. This AgRP-to-BRS3 circuit may therefore underlie the process through which hunger can redirect an animal’s motivations from caring for offspring to foraging for food.

Using single-cell RNA sequencing and neuronal manipulations, we identified an MPOA population important for parenting and satiety: bombesin receptor subtype-3 (BRS3) neurons. Activation of these neurons can even make some virgin males (which typically attack pups) more parental.
