How animals sense Earth’s magnetic field is one of biology’s enduring mysteries. Researchers in Science have now 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. Learn more in this week's issue: scim.ag/4uAKQDl

Ancient and modern dingo DNA reveals eight genetically distinct groups of dingoes – and the limited influence of domestic dog genes. theconversation.com/new-dna-…

New study of 300 dingoes using aDNA shows they retain ~90% dingo ancestry. Dog genes are limited, linked to human areas and control. Insights could help improve conservation strategies 🐕🧬@ConLetters conbio.onlinelibrary.wiley.c…

Past whaling nearly wiped out bowhead whales. By mapping logs, researchers find that sea ice slowed whalers & created natural refuge. This helps explain why some populations rebound faster today🐋🐋 @PNASNews @Smilodontology @DamienFordham @Carsten_Rahbek pnas.org/doi/10.1073/pnas.25…

Can rewilding save the planet? I gave my answer on BBC Radio's The Inquiry — and so did some of my colleagues. Tune in and see if you agree. bbc.co.uk/sounds/play/w3ct72…

Paul R. Ehrlich, author of The Population Bomb, has died, a great scientist, biologist, and naturalist who helped shape the world’s thinking Many will remember him first for The Population Bomb, hugely influential, fiercely debated, and impossible to ignore. But that was only one part of a much larger scientific life. Paul was a leading figure in population biology and conservation, and he helped shape the field of coevolution. Yet Paul was also, in the deepest sense, a naturalist. Originally trained as an entomologist, he began as a butterfly researcher, and that grounding in close observation of living systems remained with him throughout his career. Even when he addressed the largest planetary questions, his thinking was rooted in biology and in the natural world itself. What I will remember most is not only the scale of his influence, but also his intellectual courage. He was willing to say what he believed the science demanded, even when it was uncomfortable, controversial, or unwelcome. Many debated his conclusions, and that too is part of his legacy. But no one can deny the force of his contribution. He helped ensure that biodiversity loss, ecological limits, and humanity’s pressure on the living world could not simply be pushed aside. Scientists of Paul’s kind are rare. He did not merely add to knowledge; he altered the terms of debate. The news of his passing was not unexpected. At 93, Paul had lived a rich and full life. Still, I write this with sadness. I had the privilege of knowing him as a fellow scientist working in much the same intellectual terrain, and I experienced his work not as a distant reputation, but as part of the living fabric of our field. Hearing of his death brought back fond memories of a birding trip together in the Oaxaca region of southern Mexico many years ago, and our shared joy when we saw the endemic and beautiful Red Warbler, an iconic and much sought-after species of those mountains. The legacy of Paul Ehrlich endures not only in science, but in the way the world thinks and talks about human population growth, biodiversity, and humanity’s place within nature.
