Academics and technologists are sounding the alarm about a growing crisis in scholarship as we know it: AI-generated citations of nonexistent papers that have infested real journals. Despite being fake, the sources are widely assumed to be authentic the more they appear in published literature.
AI Is Inventing Academic Papers That Don't Exist -- And They're Being Cited in Real Journals
Academic articles from authors using large language model are creating an ecosystem of fake research that threatens human knowledge itself.

Women, non-native English speakers & those form low-income countries are disadvantaged in science but by how much? We found that women with non-English first languages from low-income countries publish up to 70% fewer in English than their counterparts. 1/5

Ever wonder how birds are able to identify their nest? Jennings et al. show that nests can become scented like the birds that occupy them, which may enable birds to use olfaction to accomplish this critical task.

This year marks the 100th birthday of #bioacoustics, established by Ivan Regen in 1925, which studies how animals hear, produce and propagate sound.

Let’s discover this discipline with @nicolasmathevon.bsky.social, Professor of Saint Etienne University, in the first episode of Acoustic World.

Natalie and I have resubmitted a revised manuscript about the behavioural responses of tropical wrens to simulated predators. Great revising @natingui.bsky.social! Fingers crossed for a positive outcome. Our 3D-printed Ferruginous Pygmy-Owls were made by @lincolnsavi.bsky.social.

Grateful for the opportunity to present my postdoctoral research in the Mennill Lab at #AOS2025 on vocal behaviours of Rufous-and-white wrens in the presence of an owl predator near and far from the nest.

It was wonderful to reconnect with old friends and meet new ones. 🐦🎶🦉
