Can you hear a forest disappear?
In this episode of Science Quickly, filmmaker and journalist Leah Varjacques takes us to a Bornean rainforest area, where centuries-old patterns of human and wildlife behavior are being disrupted by the construction of a new capital city. In the midst of all this change, Varjacques documents the work of Wendy Erb, a primatologist and bioacoustic scientist at the Cornell Lab of Ornithology. Erb’s team, working with members of the local Balik population, placed audio recorders around the forest to capture the sounds of this diverse ecosystem before it changes forever.

The doctor fighting for pain-free IUDs
In this episode of Science Quickly, Rachel Feltman speaks with Helena Kopp Kallner, an ob-gyn and a professor, about her promising new study that shows local anesthetic can reduce pain during placements of intrauterine devices (IUDs). These devices are one of the most effective and convenient forms of birth control, but the pain of insertion keeps many patients away. Kopp Kallner explains why IUD insertion pain has long been ignored, how existing pain-relief options fall short and why patients themselves may be the key to driving adoption of this evidence-based approach.

Who’s accountable when AI goes wrong?
When news broke that OpenAI agents had breached the AI platform Hugging Face, many headlines framed it as a case of “rogue” artificial intelligence acting on its own. But how much of that narrative was reality, and how much was hype? In this episode, Rachel Feltman speaks with AI researcher and artist Eryk Salvaggio about what really happened, why human design choices played a central role and what the incident reveals about accountability in an age of increasingly powerful AI systems. Recommended Reading: “Rogue AI didn’t breach Hugging Face, human decisions did,” by Eryk Salvaggio, in the…
