New preprint to share! Incredible collab w/ Fei Chen’s lab: developed in vivo CRISPR screening platform for 🫁 epithelium, allowing single cell perturbation in post-flu repair. Take a peek to see what we found! Huge congrats to the leaders of this work @daisyah.bsky.social & @sundakao.bsky.social 🎉

1st McKinley Lab grad student’s 1st preprint! @claireang.bsky.social studied how the uterus safely excises massive amounts of tissue during menstruation and pregnancy. Come for her GORGEOUS images, stay for her incredible discoveries. www.biorxiv.org/content/10.6... w/ @akelleher1017.bsky.social

The data is in: the NIH goalposts have shifted. What were once almost certain fundable scores have become coin flips and what used to be likely grants have become aspirational, leading to fewer awards. Another manifestation of how HHS policies have led to fewer awards and less science.

I am so proud to share @forrestdrogers.bsky.social’s postdoctoral magnum opus, now out in @nature.com! Forrest discovered a novel role for Agouti in the MPOA of the hypothalamus to integrate socio-environmental information to flexibly tune paternal behavior www.nature.com/articles/s41... Thread! 👇🏻

It’s that time of year for me to dust this thing off and encourage you to apply to be a Leading Edge fellow, this year named in honor of Zara Weinberg

Applications are open for the 2026 Zara Weinberg cohort of Leading Edge, named in honor of the incredible, brilliant, fearless @weinberz.witchlab.org. The LE community has been truly transformative for my scientific journey and my happiness. Please apply!! www.leadingedgesymposium.org/apply/

I’d given up on social media, but I was missing too many cool papers. Case in point: this incredible new study from @cagricevrim.bsky.social and @karalmckinley.bsky.social. Simply amazing!

The Sosa Lab is going to #SfN25 and actively recruiting ✨postdocs✨ with systems neuroscience experience! We study both fundamental memory processes and how memory changes during pregnancy and postpartum. If you are interested in meeting at SfN, please email me! www.sosaneurolab.com/join/postdoc...

The Leading Edge community has been a life-line as I navigate *points to everything*. Zara was such a shining light of wisdom and warmth. She will be sorely missed, but her legacy will continue in everyone who had the utmost privilege to interact with her. Apply, apply, apply!!!!

Thrilled to start my Group Leader adventure with these and other great scientists!

This program changed my life. Apply!

Zara was a star, a cherished friend, and an untiring advocate. I wish she had the chance to stay here with us and help create a brighter future, but she already gave us so much in her time here. I'm glad she will be honored in the next cohort of LE fellows ❤️

Being a leading edge fellow has been the single best thing for my scientific career. Zara’s voice and vision was no small part in that. Apply. Apply. Apply.

The Leading Edge Fellows gathered this week to celebrate Zara Weinberg, a beloved member of our community. Our 7th cohort of Leading Edge Fellows (2026) will be named in her honor. The Zara Weinberg Leading Edge Cohort application is now open! Due Feb 2. www.leadingedgesymposium.org/apply/

Zara was an incredibly inspiring scientist, activist, and leader within our community of Leading Edge Fellows. She will be deeply missed by all those who had the pleasure of interacting with her.

We are all better because of the energy, inspiration, brilliance, and tenacity that Zara was. A bright light, role model, advocate & snarky tweeter... everything I needed in a person when I was navigating dark times when we met in 2021. You will be missed deeply, Zara, but never forgotten ❤️

Zara was an inspiration. We never met in person but became friends through Leading Edge. She zealously advocated for her ideals, but was also passionate about helping others realize why they should too. Her loss is gutting & the world is the worse for it. RIP, I'll do my best to continue the fight.

In my lab, she brought such fire to the science and inspiration. She kept doing lab work til she lost mobility due to her love for science and being around the lab. She was a dedicated mentor with sharp wit and bright ideas. She contributed foundational to all our projects and training everyone.

There are no sufficient words for how profound an impact she had on the Leading Edge community. I'm so sorry for your and all of our loss. We will miss you terribly, Zara

Zara Weinberg passed away earlier this week. She joined my lab earlier this year when her postdoc lab formally closed. She was a brilliant scientist, supportive mentor, dear friend, avid music fan, rabid believer in public transit, open science champion, and above all just an amazing human.

Zara Weinberg was a brilliant, loving, and beautiful woman. She inspired everyone who she interacted with, and always strived to make the world a better place for everyone. Tho the world is a little less bright today without her, her memory will always be a blessing. She was truly one of the best.

Zara Weinberg was a brilliant light both in and out of science. She changed the lives of everyone she interacted and loved for the better. Her legacy will live on through all of us and we will fight for a better world on behalf of her memory.

The mice could be used to better understand and treat heavy menstrual bleeding, and study reproductive health conditions such as endometriosis. https://scim.ag/473mwRw

Beautiful research from the lab of HHMI Freeman Hrabowski Scholar @karalmckinley.bsky.social

Thrilled to see our preprint featured in Science News! 🩸 Big thanks to Holly Barker for writing such a thoughtful piece about our work. So exciting to see broader attention to menstruation research and new model systems! www.science.org/content/arti...

Whoa, this is big…

The Zwick Lab website is live! 🔬🌀🌈
Check out our research and team at www.zwicklab.org

This is an amazing story and important breakthrough! Awesome stuff from @karalmckinley.bsky.social and @cagricevrim.bsky.social

The kind of surprise that keeps me on social media. Another preprint to check out.

One of the coolest projects I've seen in years - huge congrats to Çağrı and the McKinley team!

Amazing work - and this will open so many doors for women health care. It's insane how little we know about female physiology. Congratulations @cagricevrim.bsky.social and the team on this incredible endeavor! 👏🏽🎉 #womenhealth 💪🏽

We’re so excited for our 5th annual HBPA symposium, Friday December 12th at HMS We are now accepting abstracts for: -Oral Presentations -Poster Registration Link: docs.google.com/forms/d/e/1F... Abstract Submission Link: docs.google.com/forms/d/e/1F... Deadline for Abstract Submission: 10/31/25

An epic story and a must read. This is really beautiful work to understand the most amazing monthly regeneration event - menstruation. The authors reconstitute this process in mice (which don’t normally menstruate) allowing important new insights. Will also be a powerful model for future work.

Congratulations @karalmckinley.bsky.social & lab on their groundbreaking recent preprint establishing + characterizing a chemically inducible model of menstruation in mouse: www.biorxiv.org/content/10.1... My jaw dropped when I heard this presented earlier this year. Incredible.

OMG 😱 a true game changer for biology! Menstruation is a natural miracle of tissue regeneration. Amazing biology to come!

This is probably one of the coolest and most creative mouse models I’ve ever seen!

Lab’s 1st preprint! Menstruation is understudied due to societal taboos + a biological challenge: mice (a key system for research + drug discovery) don’t menstruate. @cagricevrim.bsky.social made menstruating mice + used them to discover early events in menstruation. He is on the job market!

I’m extremely honored to be a recipient of the NIH Director’s Pioneer Award!

Incredibly proud of @eulalieliorzou.bsky.social who is receiving the L'Oreal-Unesco Prize for Women in Science for her trailblazing PhD work on menstruation and its associated diseases! www.pasteur.fr/fr/espace-pr...

For every Nobel that goes to a criminally under-recognized woman scientist (Brunkow, Karikó), or fails to go (Candy Lee), a week of mourning and reform for an academic system wherein you can do Nobel-prize-worthy-work and still end up without a conceivable path to being a professor.

A huge shoutout to all the dedicated grants management specialists at the NIH who are working around the clock to push grants out before the Sep 30 deadline. And also to the POs responding to frantic emails. Not an easy job under the best of circumstances and right now it's the pits. Thank you!
