We summarize the week's scientific breakthroughs every Thursday.
Samples collected at daring heights provide evidence for an untested theory of tree drought adaptation, while countering another.
The Smithsonian Natural History Museum’s latest exhibit, “From These Lands,” connects visitors with America’s natural history.
Walking sharks crawl on their fins across reefs and even out into tide pools. The newfound Dudgeon walking shark brings the known species count to 10.

How animals navigate by Earth's magnetic field is hotly debated. New research in pigeons points to iron-laden liver immune cells as the compass.
Lab experiments suggest mosquitoes can smell DEET and learn to associate it with food, but it’s unclear whether that happens in the wild.
Scientists rethink their ideas after experiments. AI agents struggle to learn from evidence and recognize when an idea is obviously incorrect.
Scientists use simulated dinosaurs to trigger real insect brains and test how wings originally evolved.
