I'm delighted and honoured to share that I've taken on the role of Editor-in-Chief of Animal Cognition! This journal has shaped how we think about cognition across species. Huge thanks to Debbie Kelly for 10 years of vision and leadership, and for all her guidance during my time as associate editor.

When you start running, your breathing speeds up before your body needs the oxygen. Turns out flies do the same thing and @camellyc.bsky.social worked out the circuit that makes it happen. Check out our new preprint on how the nervous system coordinates breathing with movement.

1/8 Breathing seems automatic. But it's a finely tuned motor behavior that has to be controlled. In this preprint, I map the circuits that match a fly's respiration to the metabolic demands of flight and mitigate the risk of dehydration. 🧵🪰 www.biorxiv.org/content/10.6...

Really cool study by the Stanewsk's lab...A beautiful example of behaviour controlling internal state! When constant light disrupts their circadian clock, flies seek darkness and can restart molecular and behavioural rhythms, with improve sleep. www.science.org/doi/10.1126/...

Fruit flies actively restart their circadian clock by proactively shaping their environment

Circadian clocks provide adaptive advantages, enabling organisms to adjust their physiology and behavior to daily environmental changes on Earth. Here, we show that fruit flies prefer a temporally org...

Raced home from vacation so we could submit and preprint postdoc @keisukefukumura.bsky.social's paper! It's an exciting first foray for our lab into the periphery, where we find a unique role for CLOCK in regulating lifespan on high fat diet. 🧪https://doi.org/10.64898/2026.07.20.739608

How does the brain represent the value of knowledge? In our paper--out now at Nature Neuroscience--we identify a representation of intrinsic information value within neural population structures in the orbitofrontal cortex in mice. www.nature.com/articles/s41593-026-02377-y #neuroskyence 🧠🧪 (1/8)

Marco Gallio talks about how snow flies adapted to cold temperatures. Through comparative genomics he discovers a high abundance of Zinc-fingers in snow flies. Can snow flies produce heat through mitochondria thermogenesis to buffer cold temperatures for a short time?

Finally out in @natneuro.nature.com! A forgotten memory isn't always gone. We show that forgotten memories persist as silent memory traces, can be recovered by reminders, and can even be reconstructed into false memories. Excited to finally share this work! www.nature.com/articles/s41...

An elegant approach to dissect the cell autonomous role of wild type huntingtin. Really nice study by @muraronara.bsky.social and lab. Congrats!

New preprint! 🧠🧠🧠What does normal (non-disease) huntingtin do in a neuron? We knocked down htt in just 8 circadian pacemaker neurons (sLNvs) of the fly brain, small enough to isolate cell-autonomous effects from network effects. Please share! doi.org/10.64898/202...

Preprint Alert! Walking mostly feels natural and easy to us - but the neuronal control of walking is actually incredibly complex. We leveraged the fruit fly as a genetically tractable animal model with a compact nervous system to ask how the brain controls walking direction: tinyurl.com/flywalk. 🧵..
