Emory University Biology Department tenure-track assistant professor position in neuroscience - Atlanta, Georgia job with malia.escobar@emory.edu | 675335 Candidate uses experimental approaches to examine any aspect of neural function, including molecular, cellular, systems, or developmental neuroscience

Come be my colleague! Lots of exciting science, fantastic students and supportive colleagues. Emory University Biology Department tenure-track assistant professor position in neuroscience. share.google/945Jko4W1MTA.... Please feel free to retweet and share widely.

We hope these findings are useful to those studying mouse social behavior! Congrats to former undergrad Stephen Batter, whose honors project kicked off this study. Thanks also to co-first authors Patryk Ziobro and Cass Malone, and to our current undergrads who helped bring this to the finish line!

Interestingly, there is past work showing that mice will forgo reinforcers (even cocaine and amphetamine) to gain access to a running wheel. So one possibilty is that running wheels are like crack for mice and decrease their sensitivity to other rewards, perhaps even social rewards.

These effects on social behavior are somewhat long-lasting, as they're not reversed by a 2-week period with running wheels removed and replaced with a standard paper hut.

Unexpectedly, we found that free access to running wheels in the home cage, either for 5-weeks over adolescence (weaning till adulthood) or even for a 2-week period in adulthood, inhibits social motivation in group-housed female mice when they are given the chance to interact with a novel female.

New story to share! We routinely put running wheels in our mouse cages. The mice love them, and there's lots of evidence that exercise is great for health. Given our focus on social behaviors, though, we wondered whether running wheels change mouse social behavior.

Controlling the media is one of the items on the authoritarian checklist; this includes not just hard news, and increasingly social media, but also threatening satirists who mock the regime.

Report: You To Be Fired For Reading This Headline About Charlie Kirk

Dear Dr. Bhattacharya: I have listened to your performance on the “War Room” podcast with Steve Bannon. The segment begins with a discussion of Secretary Kennedy’s recent cancellation of $500M worth of contracts related to mRNA vaccines. You say “You can’t have a platform where such a large percentage of the population distrusts the platform as we use it for vaccines and expect it to work.” Later, you make comments that might explain why a large segment of the percentage distrusts this platform. For example, you say that the vaccine was not protective against contracting COVID and cite your own case on COVID after being vaccinated. However, you fail to cite the evidence for the clinical trials that led to the Emergency Use Authorization.

I listened to Bhattacharya on Steve Bannon's "War Room" podcast.

If you want to know how it went, see the following email that I just sent.

Agreed!!

New study from the lab! A follow-up to our finding that short-term social isolation promotes same-sex mounting in female mice. Led by grad student Cassidy Malone and post-doc @xinzhao322.bsky.social, with help from undergrad Selina Xu!

PhDone! Congrats to my student Nicole Pranic for successfully defending this week! We were too busy celebrating to take a picture, lol.

Published an op-ed for @cnn.com: “Nobel laureate: I owe America my success. Today, its scientific future is in danger.”
A personal reflection on what’s at stake as science funding gets slashed. I’d be grateful if you could amplify both in and beyond the science world.

These results set the stage for future work to investigate how changes in brain circuits important for vocalization enable the context-dependent regulation of vocal communication over development. Stay tuned!

In this study, we present evidence that mice begin producing social USVs earlier than thought, between postnatal days 20-24. Even though these early social USVs are produced at low rates, they're pretty well coordinated with non-vocal social behaviors (sniffing/following), as in older mice.

Baby mice produce "isolation" ultrasonic vocalizations (USVs) when separated from the nest, and adolescent and adult mice produce "social" USVs during interactions with social partners. But the timing of this transition in vocal communication is not well characterized.

Vocal communication changes over development! Infants of many species produce distress calls when in need of parental care. As juveniles mature, they begin producing "adult-like" vocalizations in a variety of species-typical contexts, including during interactions with conspecifics.

Vocal ontogeny in Mus musculus Infants of many species produce distress calls when in need of parental care. As they mature and gain independence from caregivers, juveniles stop producing infant calls and begin producing adult-like...

Another study to share, led by my grad student Nicole Pranic! Before diving in, I'll add that Nicole (who is clever, tenacious, and interested in neural changes that underlie developmental changes in social behaviors) is looking for a post-doc position! Please RT!
