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

New publication from our lab, in Science Advances: Synaptic targets of circadian clock neurons influence core clock parameters www.science.org/doi/10.1126/...

New publication from our lab: Sexually dimorphic and clock gene-specific effects of artificial light at night on Drosophila behavioral rhythms royalsocietypublishing.org/doi/10.1098/...

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...

Our department at The University of British Columbia in Vancouver (Canada) is running two faculty searches. One is a joint hire with the Institute for Healthy Aging, one a cohire with the Math Dept cps.med.ubc.ca/careers-2/ Click on “Faculty Positions” on the page. Please help spread the word!

Extra kudos and thanks to all the staff at NIH and NSF and other federal funding agencies for working extra hard in very small windows of opportunity to get grants reviewed and funds released before the attention-addled federal policies change again (on an hourly basis).

We are looking for 2 postdocs to join my lab at Sussex University in Brighton, UK (South of London, on the sea). One position is for a molecular/cell biologist, the other, for a neurobiologist/behavioural person. Drosophila experience desirable. Flyer w/more info below. Please repost. Thank you!

#Circadian #Biology has grown into an incredibly broad field, one that you can now learn the fundamentals of through a clear, concise, and expertly written book. For free. Read it here and share it with your students and peers: doi.org/10.21827/686... [doi.org] #chronobiology #SciComm 🧪

Hi folks — What federally-hosted data sets do you use for your research? Please reply below. I'm especially curious about more obscure .gov data sets that might be research critical for you. (And I'm interested to hear about data sets in any domain, not just life sciences!)

Thanks to all who have expressed a willingness to support FlyBase. The wheels of bureaucracy are large and grind slowly. We expect to have a fee process in place by July. @flybase.bsky.social

New preprint from lab: www.biorxiv.org/content/10.1... Sexual dimorphism arises not through wholesale transcriptional reprogramming, but via selective sex-specific survival of neurons defined by birth order and shared developmental programs.

Almost all Nobel Prizes are awarded for work that is exploratory, or absolutely basic science with no obvious commercial or medical benefit. You cannot predict where advancements come from, so you have to invest in science and scientists. Targeted (corporate) science investment will never do this.

Featuring work from CSHL fly course alumna @aishwaryaramak6.bsky.social !!!

Nice highlight of super cool new study from @mariadelapax.bsky.social and co-authors! Congrats to all! www.pnas.org/post/journal...

Very smart, high ROI initiative from the Spencer Foundation. Providing bridge funding for canceled NSF grants: 1) directs funds to projects already screened by a top-noch review process. 2) avoids imposing proposal prep costs on researchers. 3) ameliorates the disruption from GOP sabotage.

Too pretty not to be shown, indeed

FlyBase, a crucial resource for drosophila research, has lost its funding because its grant is awarded to Harvard. The team is scrambling to find other sources of funds, including donations from labs. Read more: www.thetransmitter.org/community/fl... @flybase.bsky.social

The current fundraising link is for EU labs to support FlyBase UK group. Still setting up to collect fees from U.S. and all other labs. Stay tuned. Divided because of recent international firewalls.

Great to see @ascbiology.bsky.social join 52 other science societies in a letter to Congress expressing concern over recent organizational and financial developments at NSF, and urging Congress to exercise its oversight authority to preserve American STEM leadership 1/n aas.org/sites/defaul...

71.5% proposed cut to NSF BIO directorate.

Hundreds of National Science Foundation staffers turned out for a group photograph to celebrate the besieged agency’s 75th anniversary—despite efforts by NSF officials to prevent the picture from being taken. scim.ag/4jcGpIt
