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!

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...

Finally! 🤩 Our position piece: Against the Uncritical Adoption of 'AI' Technologies in Academia:
doi.org/10.5281/zeno...

We unpick the tech industry’s marketing, hype, & harm; and we argue for safeguarding higher education, critical
thinking, expertise, academic freedom, & scientific integrity.
1/n
Abstract: Under the banner of progress, products have been uncritically adopted or even imposed on users — in past centuries with tobacco and combustion engines, and in the 21st with social media. For these collective blunders, we now regret our involvement or apathy as scientists, and society struggles to put the genie back in the bottle. Currently, we are similarly entangled with artificial intelligence (AI) technology. For example, software updates are rolled out seamlessly and non-consensually, Microsoft Office is bundled with chatbots, and we, our students, and our employers have had no say, as it is not considered a valid position to reject AI technologies in our teaching and research. This is why in June 2025, we co-authored an Open Letter calling on our employers to reverse and rethink their stance on uncritically adopting AI technologies. In this position piece, we expound on why universities must take their role seriously toa) counter the technology industry’s marketing, hype, and harm; and to b) safeguard higher education, critical thinking, expertise, academic freedom, and scientific integrity. We include pointers to relevant work to further inform our colleagues. Figure 1. A cartoon set theoretic view on various terms (see Table 1) used when discussing the superset AI (black outline, hatched background): LLMs are in orange; ANNs are in magenta; generative models are in blue; and finally, chatbots are in green. Where these intersect, the colours reflect that, e.g. generative adversarial network (GAN) and Boltzmann machine (BM) models are in the purple subset because they are both generative and ANNs. In the case of proprietary closed source models, e.g. OpenAI’s ChatGPT and Apple’s Siri, we cannot verify their implementation and so academics can only make educated guesses (cf. Dingemanse 2025). Undefined terms used above: BERT (Devlin et al. 2019); AlexNet (Krizhevsky et al. 2017); A.L.I.C.E. (Wallace 2009); ELIZA (Weizenbaum 1966); Jabberwacky (Twist 2003); linear discriminant analysis (LDA); quadratic discriminant analysis (QDA). Table 1. Below some of the typical terminological disarray is untangled. Importantly, none of these terms are orthogonal nor do they exclusively pick out the types of products we may wish to critique or proscribe.

When we hypothesised female terns to have lower mercury levels than males due to egg laying, @matteobeccardi.bsky.social et al designed an elegant experiment to prove the effectiveness of this pathway. That proof just got published & the open access paper can be found here: doi.org/10.1016/j.en...

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

Yours truly and our mounted Great Auk (Pinguinus impennis) specimen The bird collection store, busy with visiting researchers, mounts, and in the background our volunteers who capture data from the specimen labels. It's not always this packed, but we do have a fair number of volunteers and visitors. Blue Tits (Cyanistes caeruleus) in trays in the cabinets. The collections spaces are pretty new, fresh, and functional, which is not always the case for museum collections... A tray of African raptor eggs to illustrate the breadth of the bird collection, which holds som 70K skin specimens, 60K egg clutches, and 10K skeletons.

Rant of the day: why are people still submitting manuscripts for review without line numbers? We all review papers, we all know that referring to line numbers makes easier to write the review. So, why do people keep doing this!?
