Paper alert!🧬🐦💻 Divergent selection is the textbook explanation for narrow inversion clines. Our blackcap inversion cline doesn't fit: it is wide, and the inversion is always the rarer arrangement. We show that negative frequency-dependent selection shifting between populations underlies this!

Shifting Balancing Selection Underlies an Inversion Cline in Eurasian Blackcap

We investigated what factor contributes to a cline of a chromosomal inversion of the Eurasian blackcap, which differs from typical inversion clines maintained by divergent selection. Using a simulati...

I know this is hopelessly naive but I genuinely never thought so many people would be comfortable using a website designed to help coordinate fascist activity.

This is bibliographic erasure. By framing a forced correction as internal discovery, journals turn critics into "invisible correctors", scrubbing their labor from the record. It might protect a brand, but kills scientific rigour. We need a system that cites its critics, not one that buries them.

Pick up the nearest book. Open to page 42 and post your second sentence. Add #page42 and include this rule as a reply. In a similar way, by discretizing time, we can use a binomial distribution to represent the number of events that occur over some period of time t.

Just a few days left to apply to the PhD position in our group. It focuses on selfish genes in #fungi and how they might affect the spread of giant #TEs called Starships.

Aaron Vogan@fungage-lab.bsky.social · 9mo ago

We're looking for a PhD student! If you're interested in #fungal #genomics & #TEs, meiotic drive, or pathogens, please consider applying. The project is about toxin/antidote genes in the human fungal pathogen A. fumigatus. uu.varbi.com/en/what:job/...

AI makes everything worse, and science and all of us stupid. Authored by AI, reviewed by AI, edited by AI, published by AI. Next? cited by AI.

"Runctitiononal features"? "Medical fymblal"? "1 Tol Line storee"? This gets worse the longer you look at it. But it's got to be good, because it was published in Nature Scientific Reports last week: www.nature.com/articles/s41... h/t @asa.tsbalans.se

"Wissenschaftliche Ausbildung zielt nicht auf Effizienz ab, sondern darauf, die Fähigkeit zu entwickeln, Probleme und Fragestellungen selbst zu erkennen und zu lösen." Dieser Satz! Dass diese Selbstverständlichkeit hier überhaupt betont werden muss, zeigt um was es geht.

Our new @science.org paper is out! Cuckoos and hosts are locked in a coevolutionary arms race over egg mimicry. But how are these egg types inherited, and could this drive speciation? We sequenced hundreds of genomes to find out! doi.org/10.1126/scie... 🧵1/6

Genomic architecture of egg mimicry and its consequences for speciation in parasitic cuckoos

Host-parasite arms races facilitate rapid evolution and can fuel speciation. Cuculus cuckoos are deceptive egg mimics that exhibit a broad diversity of counterfeit egg phenotypes, representing host-ad...

“When someone says we can’t miss the boat, I ask: where is the boat going? What exactly will this technology improve? That’s rarely discussed. Since when did we become Big Tech's free PR department?” — says Nicky DRIES, Future of Work Lab at the Catholic University of Leuven

Belgian AI scientists resist the use of AI in academia

"It’s a belief eagerly embraced by the capitalist system, with venture capitalists at the forefront. If such a god can be created, and if you can gain a monopoly on it, then you not only have the prospect of great wealth, but also a great deal of power." apache.be/2025/10/24/b...

“These systems will never be able to think and provide reliable information with the current approach to AI”, says Steels. And that current approach is focused on so-called large language models (LLMs). In short, such models are ‘trained’ via machine learning to place one word after another in the most credible way possible. “Especially in the US, there’s a belief that we are dealing with a kind of god-like system”, says Steels. “A Judeo-Christian deity who supposedly knows everything, sees everything, understands all languages, can predict everything... And the people in Silicon Valley believe they can build this. It’s a belief eagerly embraced by the capitalist system, with venture capitalists at the forefront. If such a god can be created, and if you can gain a monopoly on it, then you not only have the prospect of great wealth, but also a great deal of power.” Katrien Beuls, an AI researcher specialising in language technology, argues that the technology has shortcomings. “We know that, and that will never change. It is inherent to this technology.” Steels agrees: “The system is powerful, but it has fundamental limitations. ‘Hallucinations’ are part of the architecture of such a system.” Those ‘hallucinations’ are outputs that make no sense, but American linguist and AI critic Emily M. Bender opposes the use of the term ‘hallucination’ because it is an all-too-human term for a non-human system. An LLM system generates plausible language that a human can interpret and understand, but it has no concept of ‘meaning’ or ‘accuracy’ of what it processes and generates.

Heads up: ignore samtools dot org, similarly minimap2 dot com and likely others. It's owned by a known phishing site and while the binaries they offer look valid currently (but note they may be serving us different binaries to others), that could change. Ie: it's not us (Samtools team)! Be warned
