This week is the gathering of the tribes around @nanoporetech.com, for their annual meeting, London Calling. It is a blend of tech announcements, product updates + scientific conference (posters and breakout talks). I am only there for the informatics day at the end sadly, but here are some thoughts

🐻New preprint🐻 We analysed WGS data from the Apennine brown bear—a small and isolated population which has coexisted with humans for millennia—and found unique genomic diversity, including adaptation associated with reduced aggressiveness. #ConsGen #Genomics #Bears www.biorxiv.org/content/10.1...

“Should AI be allowed to review papers or grant proposals” always reveals a thing I think people don’t understand about algorithmic bias 🧵

We have a new pre-print! If you are interested in #smallpopulations, here we show how selection may shape behavioral traits in small isolated populations. We also show selective signatures at genes associated with reduced aggressiveness, possibly involving alternative splicing #consgen #popgen

Struggling to find the tiny microchromosomes in draft bird genome assemblies? Our new #preprint introducing MicroFinder can help: www.biorxiv.org/content/10.1... 🧵 below (1/n) @sangerinstitute.bsky.social

Lol what?! ""The Magic School Bus," "3-2-1 Contact," "Reading Rainbow," "Zoom" and "Bill Nye the Science Guy" were just a few of the early NSF-funded shows that took an innovative approach to bringing science to life on the small screen. " www.nsf.gov/science-matt...

Repeats in DNA can form structures other than the typical double helix. Using newer techniques, we can see the repeats and predict their non-helical structures better. There are a lot of super cool things that will come from this work, thanks to @linneasmeds.bsky.social and team! 🤩

Very proud of my colleagues and friends for their amazing publication out in Science today! Nunes et al. "Admixture’s impact on Brazilian population evolution and health" www.science.org/doi/10.1126/... @hunemeier.bsky.social @macscastro.bsky.social 👏

Big thanks to @grrlscientist.bsky.social for featuring our work in Forbes magazine! tinyurl.com/h8yj5cdf The piece covers our recent study on time-lagged genetic diversity loss in the critically endangered regent honeyeater, published last week in @royalsocietypublishing.org tinyurl.com/44m3b522

I once asked a scientist whom I respect enormously her advice for a successful career and life in science. Her advice: Leave every place better than you found it. It surprises me that many people would try hard to do the compete opposite … and we would elect them to run the country.

🌊🧬Revolutionizing Biodiversity Monitoring?🧪 Could aquatic #eDNA be a game-changer for tracking biodiversity loss? From detecting invasive species to restoring ecosystems...🌍 Study by Altermatt, F., Couton, M., Carraro, L. et al.: www.nature.com/articles/s44...

Stoked to be able to share my first postdoc paper: 𝘔𝘢𝘳𝘪𝘯𝘦 𝘮𝘦𝘨𝘢𝘷𝘦𝘳𝘵𝘦𝘣𝘳𝘢𝘵𝘦 𝘮𝘪𝘨𝘳𝘢𝘵𝘪𝘰𝘯𝘴 𝘤𝘰𝘯𝘯𝘦𝘤𝘵 𝘵𝘩𝘦 𝘨𝘭𝘰𝘣𝘢𝘭 𝘰𝘤𝘦𝘢𝘯, published today in Nature Communications! 🎉 www.nature.com/articles/s41...

Repost w/ correct link! The Dept of Human Genetics at the Univeristy of Utah is hosting a Rising Stars in Genetics & Genomics postdoc symposium. We are looking to feature postdocs doing cool science! Please self nominate or nominate an excellent postdoc! #ASHGtrainees docs.google.com/forms/d/e/1F...

Researchers and administrators are exploring ways to restructure a rigid hierarchy that can breed power abuses. https://go.nature.com/3YwJziZ

We sequenced and analyzed the world's rarest large mammal, the #saola 🦄. That turned into a cool paper substantially increasing what we know about this elusive animal, its evolutionary history, population structure, and long-term decline. Check it out here 👇 www.cell.com/cell/fulltex...

“Can genomic analysis actually estimate past population size?” by Janeesh Bansal & Richard Nichols Before simply answering “no," take a look at the article, in which the authors propose how to gain useful insights from modern algorithms (SMC methods). authors.elsevier.com/sd/article/S...

Apparently not all my popgen advice is good.

On the ancestry and evolution of the extinct dire wolf https://www.biorxiv.org/content/10.1101/2025.04.09.647074v1

Inside me there are two wolves. One of them has a 15 genome edits the other 20 genome edits. Neither of them is a dire wolf.

Our study ‘The #global #human impact on #biodiversity’ is out in @nature.com: www.nature.com/articles/s41... 🌍🌐🐟🌿🪲 Unprecedented synthesis of >2000 studies led by @francoiskeck.bsky.social shows humans are not only shrinking species numbers—but reshaping entire communities across the planet. 🧵1/5

It’s the first time a frog—or any amphibian—has been observed pollinating a plant, researchers reported in 2023. Learn more on #WorldFrogDay: scim.ag/4kGdvCy

I have been doing entirely too much earnest posting about deep things recently, I need to do a proper thread about hippo testicles or something just to keep myself sane. Oh by the way hippos have migratory testicles.

The #IPCC & #IPBES, well-known, established organizations, are different global #SciencePolicyInterface models. With major experience in both @pammcelwee.bsky.social reflects on the models & argues for involving diverse knowledges, new stakeholders & expanding communication doi.org/10.1007/s105...

Sea turtles are considered one of the oldest living species on Earth, but it's been a mystery where their babies go after heading out to sea — a period known as their “lost years.” @katemansfield.bsky.social and her team of marine scientists at UCF are working to change that. John Yang reports.

This #WorldWildlifeDay, we call for urgent action to halt biodiversity loss. Preventing extinctions, protecting genetic diversity, & addressing human-wildlife conflict are key to achieving Target 4 of the Kunming-Montreal Global Biodiversity Framework.

Peto's Paradox—that cancer does not increase with body size of mammals—was wrong. A new, comprehensive study of 263 species documents higher cancer prevalence with increasing body mass.

Loved this post from a postdoc who lived through the Bolsonaro years in Brazil: "The best 'fuck you' to fascists? Thriving. Publish that paper. Build that collaboration. Laugh with labmates. Science outlives dictators—but only if we stay in the fight." www.reddit.com/r/labrats/co...
