Looking forward to #Dros26 this week. My lab is recruiting and I would be delighted to chat with anyone interested in grad school/postdoc positions in evolutionary cell biology and developmental genetics. Please reach out if interested!

Quick plug for our new resource, the Drosophila Species Stock Exchange. This is a database and mailing list that documents species currently in culture and the labs holding them. If you want to know more or sign up then please get in touch. See attached for more info and please share!

I am glad to say that the first manuscript from the lab is now available on BioRxiv
https://www.biorxiv.org/content/10.1101/2025.10.30.685496v1
We set out to answer a simple question:
If the fruit fly #Drosophila cannot see clearly, how would they #sleep?

New paper out: www.nature.com/articles/s41... 🥳 Congratulations to our PhD student Katja for her inspiring work just published in Nature Communications on how the larval zebrafish brain processes multiple visual features.

Check out a short summary of the work here: tinyurl.com/yzv4ct9k

When a fly lands on your arm, how does your nervous system decide where to swat?

By reconstructing tactile axons in a Drosophila connectome, we found a leg somatotopic map and downstream circuits that sample the map to initiate targeted grooming

Excited to share our latest work in @nature.com showing shared neural substrates for parenting and prosocial helping behavior. Full text available here: rdcu.be/e6PnY

After several years of work, my lab is starting to put out our first papers on learning in a unicellular organism (Stentor coeruleus).

Here we show evidence for a form of associative learning in Stentor:

Join us at the Evolutionary Biology Centre at Uppsala University. We’re searching for an Assistant Professor in Biology. www.uu.se/en/about-uu/...

Insect research has used Drosophila as a model organism for over a century. But today’s tools now open up a much wider spectrum of insects which deserve to be studied. See the recent commentary in @fly-journal.bsky.social by @peterkdearden.bsky.social, ‘Why just fly?’ doi.org/10.1080/1933...

Excited to be co-organising a #cosyne2026 workshop with Alison Comrie on 'algorithms for learning from scratch'! With a great line-up of speakers, we'll be tackling the question of what processes enable naive biological & artificial agents to adapt to new situations. Info here: tinyurl.com/4u8enf7k

Dynamics of glia and neurons regulate homeostatic rest, sleep and feeding behavior in Drosophila - Nature Neuroscience Animals alternate between active periods and periods of rest or sleep. This study in fruit flies points to brain metabolism as a cause for this and shows that a network of glial cells interacting with...

Using our bee-tracking drone, we discovered that honey bees 🐝 have highly precise and individual routes. Now published at @currentbiology.bsky.social : doi.org/10.1016/j.cu...

Neuroscience has a species problem If neuroscience is serious about building general principles of brain function, cross-species dialogue must become a core organizing principle.

If neuroscience is serious about building general principles of brain function, cross-species dialogue must become a core organizing principle rather than an afterthought, writes @suthanalab.bsky.social.

New lab preprint! Can we study conscious perception of gut sensations in mice to reveal its neuronal basis? Can we train mice to report their gut sensations? Omer Rafael and Stav Shtiglitz in the lab teamed up to discover that…YES! Thread…1/6 www.biorxiv.org/content/10.6...

Starvation suppresses shock responses only with food odours, via a defined neuromodulatory circuit that biases action selection towards goal-directed behaviour.

To survive, animals must balance opportunity and risk. We show that hunger gates nociceptive avoidance in Drosophila, enabling food approach under conflict.

Our new preprint is out!
