Diepeveen, Bellés & @mikkelschierup.bsky.social analysed T2T primate genomes to show that several X chr. gene families evolve under strong positive selection, whereas Y chr. families predominantly show purifying selection. 🔗 academic.oup.com/gbe/article/... #societyjournal #genome #evolution

My main PhD paper is out on bioRxiv! 🎉 The microbiomes of wild animals, besides the gut, remain unexplored. To help remedy this, we used museum-preserved dental calculus to characterise the oral microbiome of 34 diverse mammal species. 💀🦠🦷 Read here: www.biorxiv.org/content/10.6...
Phylum-level composition of the oral microbiome across 34 mammal species, representing 8 taxonomic orders, 4 dietary categories, and including 3 marine species.

Researchers have identified superparamagnetic macrophages in the livers of rock pigeons to be crucial for magnetic sensing. The finding uncovers an unexpected role for immune cells in sensory perception and may fundamentally change our understanding of animal navigation. scim.ag/4nTQ3nq
How animals sense Earth’s magnetic field is one of biology’s enduring mysteries. Researchers have now identified superparamagnetic macrophages in the livers of rock pigeons (Columba livia) to be crucial for magnetic sensing. The finding uncovers an unexpected role for immune cells in sensory perception and may fundamentally change our understanding of animal navigation.
