2-year Postdoc Position: Evolution and Organization of Ant Olfactory Systems

– in Carlotta Martelli's lab at Johannes Gutenberg University Mainz, Germany.

"The ideal candidate should have a strong background in bioinformatics, ideally with practical or theoretical experience in single-cell transcriptomics or comparative genomics. A keen interest in neurobiology is essential. Additional skills in evolutionary biology, insect handling, and programming (preferably in Python) would be advantageous, but are not mandatory."

Position still open!

Shades of Yellow, Black, and Grey around 1900: "The ‘London fog’ [...] soon became as notorious an attribute [...] as ice in Moscow and wind in Chicago. In the popular imagination, it became a home and breeding ground for obscure figures and nameless, clandestine crimes." First part of of my blog post series for the German Historical Institute London "From #London Fog to Frankfurt Smog", researched in foggy November.

PhD project with Marcus Stensmyr @MarcusStensmyr :

"will address fundamental questions about how the fly's sense of smell operates. More specifically, the prospective PhD student will map the evolution of chemoreceptors in drosophilids over deep time and investigate how these receptors are used to extract sensory information from the environment. The project will utilize museomics, comparative genomics, electrophysiology, and fieldwork to trace the functional evolution of chemoreceptor genes within Drosophilidae."

Knowing Marcus a bit, it is also going to be a lot of fun. And in a great city too – Lund, Sweden.

Apply by May 5th.

Role of axo-axonic synapses among olfactory receptor neurons (ORNs) in odor decorrelation, mediated by metabotropic acetylcholine receptors:

Yes, though it’s difficult to synthesise a wide range of odours because our olfactory repertoire is so vast as to be practically infinite. #olfaction #PhilPerception www.bbc.com/news/article...

Temperature matters:

"brain connectivity scales continuously across temperatures"

With impacts on brain function:

"developmental temperature does not alter odor encoding in first- and second-order neurons, but it shifts the specificity of connections onto third-order neurons that mediate innate behaviors."

From: "Impact of developmental temperature on neural growth, connectivity, and function", by Züfle et al. 2025 (Carlotta Martelli's lab)

Tim Schwanitz and Lukas Weiss have uploaded a #postLight. 👀

They revisit work (from Einat Couzin-Fuchs & team) exploring the neuronal basis of olfactory-mediated foraging behaviour in locusts, published in #NatureComms 🦗

In any case, once a red pepper smells like that, the flavour becomes also like how I'd imagine eating an agar plate of E. coli to taste. Inedible. Gross. Means I am very wary of any pre-prepared salad with cut red pepper in. (3/3)
