Today we’re quietly (and finally!) opening up Railfinder to the public! This is our beta version and - hopefully - the first step towards that one booking site for trains across Europe that we all dream of.
Lots of work has gone into this and equally lots still to do before reach that vision, but if you’d like to try what we’ve built you can now just go to https://www.railfinder.eu and have a go!
Any and all feedback more than welcome

Fuck.
Elsewhere in their profession, some scientists are starting to look away. “We know quite a number of entomologists who have experience dating back to the 70s, 80s or 90s,” Hallwachs says. “One of our very good friends – he now does not have the emotional courage to hang up a sheet to collect moths at night. It is too devastating to see how few there are.”
What's been lost...
Entomologists from Krefeld, Germany, collected flying insects for two weeks in August 1994 (left) and—at the same site, with an identical trap— in August 2016 (right). Similar data from 63 German protected areas overall gave a shocking result: a 76 percent drop in insect biomass between 1989 and 2016.
It has worsened significantly in the past 9 years.

For the first time, researchers at #UniLeipzig and other institutions have gained comprehensive insights into the entire nervous system of the fruit fly. The findings were recently published in Nature, marking the first study to describe in detail the neurons that span the entire nervous system of the adult fruit fly: https://www.uni-leipzig.de/en/newsdetail/artikel/eine-strassenkarte-fuer-das-gehirn-der-fruchtfliege-2025-05-07

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!

How do #NeuralNetworks generate diverse and variable outputs? This study of the larval #fruitfly locomotor system shows that relatively simple sets of #inhibitory circuit motifs can generate a surprising degree of diversity & variability in motor programs @PLOSBiology https://plos.io/3GpT3pR

Maggots. We really don't give then enough credit. They can do so much with so little:

1 Join us for a 4-year PhD in Newcastle on a fun project (literally)!
Building on our recent publication about Drosophila playing on a carousel (https://doi.org/10.1016/j.cub.2025.01.025), we will explore:
1) the genetic underpinnings of play,
2) the neuronal circuits involved in play, and its adaptive benefit,
3) how environmental context impacts play behaviour.
This is what we mean when we say the regime is censuring science.

Our story about flies on carousels is out in @CurrentBiology ! After formally engaging the fantastic Clara H. Ferreira and integrating helpful feedback from our reviewers, we now present a more concise story with detailed behavioural quantification and cooler videos: https://doi.org/10.1016/j.cub.2025.01.025
Fascinating new research: across 26 countries, #radicalright politicians stand out as spreaders of misinformation. They are systematically poisoning the well of discourse. Hardly surprising, still somewhat shocking to see this backed up by data.

I'm changing jobs in the next few months, and while plans are in motion, I'm curious to hear any leads folks may have. Connectomics, bioimage analysis, ML for scientific discovery. I've ~20 years of dev experience, CS BS, ML/HPC MS, neuro PhD. Mostly interested in research, staff science, or small teams/startups/founders.
Main constraint is family bound to Leipzig, so mostly looking for remote.
It is so funny to hear people in the UK talk about "creating a Silicon Valley" or "turning the UK into a hub of innovation". There are many reasons that this has not happened and will not happen, but one of the simplest reasons is that the UK cannot attract top talent when salaries in this sector are between 20% and 60% those of the US, *including* benefits such as social healthcare.
It is very interesting to think about what these people must be smoking when they say such things...
