Snow leopards have the lowest genetic diversity of all big cats–a dubious distinction once held by cheetahs. It increases their risk of extinction in a warming climate. #Stanford-led #research #snowleopards @kasolari.bsky.social @petrovadmitri.bsky.social news.stanford.edu/stories/2025...

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. 🔗 doi.org/10.1093/molbev/msaf206 #evobio #molbio #TEsky

The paper in Nature: "Here we describe complete assemblies of three human Robertsonian chromosomes. We identified a common breakpoint in SST1, a macrosatellite DNA located on chromosomes 13, 14 and 21, which commonly undergo Robertsonian translocation." www.nature.com/articles/s41...

For decades, scientists puzzled over a genetic anomaly. They just solved it. wapo.st/3VyLmlx

Check out our pre-print: We show that L1 insertion intermediates can recombine with one another or with DNA breaks to form genome rearrangements, highlighting the risk of L1 retrotransposition generating substrates for aberrant recombination and genome instability. www.biorxiv.org/content/10.1...

Interested in repetitive DNA? We are organising a free workshop on Oct 2nd at the Botanical Institute of Barcelona! All organisms included - not only plants ;-) Last chance for registration, don’t miss it! bit.ly/repetitiveDN...

Very excited to see this work in press! I think there is a reason to believe that this is a common means of stabilizing large-effect polymorphisms in general and might be an important reason for why diploidy is so common. news.stanford.edu/stories/2025...

One of the all time greats!!! Plagiarized by Miles davis (twice).

This is such a great example of why "sex is binary" is a regressive concept in science. By studying the manifold aspects of genetic, anatomical & hormonal diversity in humans, more can be understood. In this case, the *number of copies of certain genes*, not 'sex', determines height.
