🧵Good news out of #NIH today. (1) NIH is extending #ESI and #K99/R00 eligibility to accommodate researchers whose eligibility would have ended during the previous shutdown. Take a look at NOT-OD-26-020. If your ESI status would have ended in 2025, you get an automatic extension through 2026/03/31.

What: The 2026 Indiana University Animal Behavior Conference When: March 27-28 Where: Monroe Convention Center, Bloomington, IN Conference registration is open. Abstract deadline is Feb. 13. Attendance only deadline is March 9, 2026. Learn more: go.iu.edu/8sMB

The second paper from the lab is now available on bioRxiv: www.biorxiv.org/content/10.6... We discovered that cannibalistic behavior in fly larvae is social-context dependent. Larval groups avoid dead conspecifics; individuals show high attraction. They only do it when no one is watching 😉

Can't wait to serve again as co-director of the CSHL Drosophila Neurobiology course this year! 🧪🪰👀 Application Deadline: March 27 meetings.cshl.edu/courses.aspx... @cshlnews.bsky.social @cshlcourses.bsky.social

Boom, congratulations Joel

The neuroscience community has lost a dear friend and mentor. Ed Kravitz passed away on Sunday, September 21, 2025. Here he is this past summer speaking with (and making margaritas for) the 2025 Grass Fellows, as he's done for more than two decades. Rest in peace.

Ed Kravitz passed away yesterday. He was a remarkable scientist and mentor- brilliant, curious, creative, and kind. I am grateful to have learned from him. His legacy will endure through his science and through the many people he inspired. We will miss you, Ed.

I have gotten a bit behind at sharing the lab’s latest work - this paper is now published - check it out! www.cell.com/cell-reports... Long story short: insulin is the major determinant of female fat storage, with a relatively minor effect on males.

Join us! The Division of Invertebrate Zoology at the American Museum of Natural History is hiring a curatorial associate! For more information : careers.amnh.org/postings/4529

I'm looking for PhD students to join the lab starting August 2026. We study the evolution of insect chemical signals so if you're interested in evolutionary biology, chemical ecology, molecular biology, behavior, or genetics, this could be a good fit for you! More info here: tinyurl.com/mrxchwfm

Confused writing is usually a symptom of confused thinking. As we struggle to clarify writing, we clarify our thoughts. AI writing aids rob us of that struggle, leaving clean-looking text and thoughts still confused for lack of inspection. Writing is not just a product; it is a diagnostic tool.

It takes less than a minute to donate to FlyBase—let’s support this essential resource for the Drosophila community.

My lab’s newest preprint is now available. www.biorxiv.org/content/10.1...

Join us (and @sfn.org) this Wednesday for a webinar that will explore how brains cope with changing environments. Hear from experts on recent advances in the field. Learn more: bit.ly/3HeL1kv #KavliNeuro #neurosky @rosvall-lab.bsky.social

This short read is truly excellent - thank you, Martin Schwartz!

Flybase is free to use but not free to make. It takes large teams of people and millions of dollars a year to create the knowledgebas and tools for fly research. Please donate generously.

#Drosophila community in the US and non- EU countries, please donate to help us support #Flybase. People behind the scenes have put in incredible effort over the past few months - as someone who has seen some of it first hand at #IUBloomington, they deserve all the praise. Please share and donate !

FlyBase needs your help! We ask that European labs continue to contribute to Cambridge, UK FlyBase, whereas US and other non-European labs can contribute to US FlyBase. For more information and how to donate: wiki.flybase.org/wiki/FlyBase...

FlyBase, a Drosophila database, will lose a third of its team in early October because the Harvard grant that covered the employees’ salaries was canceled. Scientists warn that losing FlyBase could devastate fly research. By @claudia-lopez.bsky.social www.thetransmitter.org/community/ha...
