Predatory aggression evolved through adaptations to noradrenergic circuits - Nature Noradrenergic circuits support and balance aggressive behavioural states in predatory nematodes, distinguish predatory from non-predatory nematode species and are associated with the evolution of comp...

Why do some worms graze on bacteria while others hunt and kill?
Our study, published today in Nature, reveals how predatory aggression evolved in nematodes.
Led by @gunizgozeeren.bsky.social and @leoboeger.bsky.social across the @jameslightfoot.bsky.social and @monikakscholz.bsky.social labs.

A study in @science.org from Paul Cohen's lab, led by @maschakoenen.bsky.social, demonstrates how beige fat directly influences blood pressure. The findings offer a new target for treating vascular disease and could lead to more precise therapies for hypertension: https://bit.ly/4pK0hGh

Neuronal calcium spikes enable vector inversion in the Drosophila brain In the fly central complex, PFNa neurons switch from firing classical sodium spikes when depolarized to firing non-canonical T-type calcium spikes when hyperpolarized. This bidirectional spiking allow...

We had a lot of fun working on this project (led by Itzel Ishida, not on bluesky). Some interesting highlights from the paper -

FERAL: A Video-Understanding System for Direct Video-to-Behavior Mapping Animal behavior unfolds continuously in time, yet quantitative analyses often require segmenting it into discrete, interpretable states. Although manual annotation can achieve this, it remains slow, s...

Our preprint is out! www.biorxiv.org/content/10.1...
Peter Skovorodnikov and I are excited to present FERAL: a new video-understanding toolkit that maps raw video directly to behavior, no pose estimation required.
It works across species, from lab to field, and even in collective systems. (🧵1/n)

From neurons to novelty: Circuit mechanisms shaping courtship evolution The vast diversity of animal behaviors has long inspired ethologists and neuroscientists, but circuit mechanisms driving this variation remain elusive…

@rorycoleman.bsky.social and I wrote an opinion piece called

'From neurons to novelty: Circuit mechanisms shaping courtship evolution'

We argue that now is a great time for neuro-evo research

How does life evolve to adapt to modern cities?

Out now in Science, my PhD work with @lindymcbr.bsky.social uncovers the ancient origin of the “London Underground mosquito” – one of the most iconic examples of urban adaptation.

Very Cool! Congrats Kelsey

🧠🌟🐭 Excited to share some of my postdoc work on the evolution of dexterity!

We compared deer mice evolved in forest vs prairie habitats. We found that forest mice have:
(1) more corticospinal neurons (CSNs)
(2) better hand dexterity
(3) more dexterous climbing, which is linked to CSN number🧵

The behavior of the flies itself. On a food patch they are much more active when in groups and so we looked into the role visual motion might play. turns out it is an important aspect of their mating behavior

Thanks Lisa!

Thanks Kelsey!

Thanks Jeff!! I'm glad you like it 🪰

People thought I was bonkers studying courtship and mating in Drosophila erecta nearly 50 years ago. Sometimes you just have to wait.

Your foundational work on this (and so many other) Drosophila species courtship has been an inspiration for us!

Thanks Mohammed! Means a lot coming from you

hahaha. should be part of any ignobel..

and of course the 🪰Ruta lab🪰 past and present #flylove

Also thanks to people who have been supportive throughout this journey - @danielkronauer.bsky.social, @brandonscooper.bsky.social, @leahhouri.bsky.social, @jennymerritt.bsky.social, @simonsfoundation.org junior fellows, @kavlifoundation.org NSI fellows and @maschakoenen.bsky.social 🪰🪰🪰

This would not have been possible without a brilliant team! Huge thanks to Katie Keller, @rorycoleman.bsky.social, @noelleeghbali.bsky.social, Sarah Zylka,
