This flower smells like injured ants — and flies can’t resist it A type of Japanese dogsbane releases a scent identical to wounded ants’ distress signal, drawing in scavenging flies that unwittingly pollinate it.

A Japanese flower smells like injured ants — a morbid perfume that lures hungry, pollinating flies straight to its blooms.

A tale of two birds: cognitive simplicity drives collective route improvements in homing pigeons Altmetric provides a collated score for online attention across various platforms and media.See more details

🌎 Collective intelligence, simplified: homing pigeons refine their routes not through expert leaders or complex learning, but by simply averaging paths across individuals.

The Nobel Prize in medicine goes to 3 scientists for work on peripheral immune tolerance Mary E. Brunkow, Fred Ramsdell, and Shimon Sakaguchi have won the Nobel Prize in medicine for their discoveries about peripheral immune tolerance.

Male CNS Connectome A team of researchers has unveiled the complete connectome of a male fruit fly central nervous system —a seamless map of all the neurons in the brain and nerve cord of a single male fruit fly and the ...

Exciting news for #drosophila #connectomics and #neuroscience enthusiasts: the Drosophila male central nervous system connectome is now live for exploration. Find out more at the landing page hosted by our Janelia FlyEM collaborators www.janelia.org/project-team....

Insect spatial memory is thought to be based on panoramic snapshots that are modelled as retinotopic images. This idea won't allow a distinction of landmarks from the scene. Unexpectedly, our data suggest that 🐝 learn 3D-objects as individual landmarks. #neuroethology

Figure showing 3 panels. Panel A: workflow of a classical deep learning model vs TopoTome workflow, with marked differences between the methods, including manual segmentation of images, design and optimization of neural network and data post processing that is needed in deep learning workflow but not in TopoTome. Panel B: core concepts behind TopoTome shown connected by arrows. From left to right, there is a microCT scan of a fly brain (3D reconstruction), a persistence barcode of H2 homologies, an image of how persistent barcodes map to the original CT brain scan, and a segmentation of a CT scan. Panel C shows the concept of cubical complex filtration of 2D and 3D image data.

🚨Preprint🚨
What started as an attempt to compare CT scans of diverse fly brains, ended up a new concept for analysis & segmentation of difficult tomographic data. No ground truths, no training, just maths. This is TopoTome, topological data analysis of 3D images

A multisensory, bidirectional, valence encoder guides behavioral decisions A key function of the brain is to categorize sensory cues as repulsive or attractive and respond accordingly. While we have some understanding of how sensory information is processed in the sensory pe...

How is valence computed in the brain? Check out our new preprint about a single cell that integrates excitatory and inhibitory input across modalities according to valence and impacts behavioral decisions. An exciting collaboration across many labs. Enjoy reading!

‘Almost unimaginable’: these ants are different species but share a mother Ant queens of one species clone ants of another to create hybrid workers that do their bidding.

woah this is genuinely, utterly WILD

Ant queens of one species produce males of another species, so she can then mate with them and produce hybrid workers!

This is so gloriously weird I can't quite compute it 🤯🧪🐜

Pregnant people often struggle to sleep and now it turns out that disrupted sleep extends cockroach pregnancies by reducing the quality of the milk that feeds the developing young so they take longer to grow. Cockroaches need their beauty sleep too!
