Constraints on chromosome evolution revealed by the 229 chromosome pairs of the Atlas blue butterfly The genome of the Atlas blue butterfly contains ten times more chromosomes than most butterflies, and more than any other known diploid animal. Wright et al. show that this extraordinary karyotype is ...

How many chromosomes can an animal have?

In our paper out now in @currentbiology.bsky.social we show that the Atlas blue butterfly has 229 chromosome pairs- the highest in diploid Metazoa! These arose by rapid autosome fragmentation while sex chromosomes stayed intact.

How Did Evolution Halve Genome Size During an Oceanic Island Colonization? Abstract. Red devil spiders of the genus Dysdera colonized the Canary Islands and underwent an extraordinary diversification. Notably, their genomes are ne

Red devil spiders from the Canary Islands have a genome half the size of mainland counterparts - Pisarenco, @jrozasub.bsky.social et al. show how purifying selection against slightly deleterious DNA and TE insertions is the primary mechanism.

Top right: Phylogeny showing sex chromosome turnover in darters and non-darter percids. Chromosome 9 is the putative ancestral sex chromosome, shared by Perca flavescens and multiple members of the orangethroat darter complex (e.g., E. spectabile, E. pulchellum). Bottom: Schematic depicting repeated turnover of sex chromosomes as a mechanism to resolve mitonuclear conflict and promote speciation.

First pop gen paper from our lab! We find repeated evolutionary turn over of sex chromosomes in darters contributes to reproductive isolation. Turnover may be an escape hatch to resolve mitonuclear conflict & neo sex chromosomes evolved via a rare recessive mutation. www.biorxiv.org/content/10.1...

One mother for two species via obligate cross-species cloning in ants - Nature In a case of obligate cross-species cloning, female ants of Messor ibericus need to clone males of Messor structor to obtain sperm for producing the worker caste, resulting in males from the same moth...

Reproduction in ants 🐜 just keeps blowing my mind 🀯

But this here is the crown for sure... for now.

Sorry for the sass, I'm just sick of seeing articles in what I thought were reputable journals, painting a canvas of futuristic AI as the Messiah that will save us from war, climate change, famine and disease "soon" with "PhD level knowledge".

Just leaving this here for any academics who still get LLMs to summarise literature for them without any critical examination of their own. Check the authors of Nature opinions pieces pumping 'AI'. Many are employees of Microsoft etc., the only people who truly profit from this.

Mike Ritchie reminded to publish in your society journals to keep things rolling. Overpriced journals from big publishers did not circle back their money to society!

Surprised the EU still need to be reminded, I thought many funding bodies acknowledged review-community platforms.

Point of View: To be, or not to be, part-time in academia Part-time working can be beneficial for individual academics, and also for academia as a whole.

To be, or not to be, part-time in academia?
This is a tricky question that has faced many of us and in @elife.bsky.social we discuss the benefits and challenges of being part-time. With @emiliapsantos.bsky.social and a fantastic, interdisciplinary team!

Does selfing allow or even lead to massive genome reshuffling, expansion and sky high homozygousity? Come and find out at posters 29 and 42 this afternoon, only at #eseb2025 and learn about an organism whose genome looks like it went through a blender and came out high repetitive and homozygous.

AI Is a Mass-Delusion Event Three years in, one of AI’s enduring impacts is to make people feel like they’re losing it.

Hello. I wrote a nice long essay about AI and this very strange moment where we're constantly told we're living in the dawn of a strange new future but the only thing that's actually clear is that everyone feels pretty unmoored and uncertain. I hope you'll read it

In the Future All Food Will Be Cooked in a Microwave, and if You Can’t Deal With That Then You Need to Get Out of theΒ Kitchen As a restaurant owner - I'm astounded at the rate of progress since microwaves were released a few short years ago. Today's microwave can cook a frozen burrito. Tomorrow's microwave will be able to cook an entire Thanksgiving Dinner. Ten years from now a microwave may even be able to run the country. Recently I was watching a livestream of a local microwave salesman.

I am wildly paraphrasing, but the best commentary I have seen so far is this:

Bringing AI into a learning institute is like bringing a fork lift to the gym. Sure, both accomplish the task at hand better than you, but you still fail do accomplish the thing you went there for in the first place.

This. My disgust for LLMs isn't just due to them being built on intellectual theft, their energy use wrecking progress made on emissions reduction, their complete financial unsustainablity, or their negative impact on our learning, critical thinking and mental health
