The secret to pigeons’ incredible navigation was hiding in their liver
The secret to pigeons’ incredible navigation was hiding in their liver Pigeons may owe their remarkable homing ability not to their brains or eyes, but to magnetic-sensing immune cells hidden in their livers. - Date: - May 31, 2026 - Source: - Max Planck Institute of Animal Behavior - Summary: - Scientists have uncovered a surprising navigation system in pigeons: iron-filled immune cells in the liver that may act like tiny magnetic sensors. Birds deprived of these cells struggled to find...
How pigeons exploit magnetic fields for navigation
Scientists have long known that migrating birds and homing pigeons navigate in part by sensing the Earth's magnetic fields, especially at night or in overcast conditions when visual landmarks or sunshine are in short supply. But exactly where this magneto-sensing occurs in the body—and the mechanism that enables it—remains a matter of intense debate. A new paper published in the journal Science suggests that homing pigeons have iron-rich immune cells in their livers that help them detect...
Woman who repeatedly fed pigeons fined S$6,500, says she wanted to 'rescue' them
A woman was fined S$6,500 after repeatedly feeding pigeons. She told the court that the birds motivated her because she felt they were unable to work, a sentiment the magistrate noted was unfounded.
Daily briefing: Pigeons might find their way by following their liver
Nature, Published online: 29 May 2026; doi:10.1038/d41586-026-01768-2Magnetic immune cells in a homing pigeon’s liver might help it to navigate. Plus, the first clinical trial of a gene therapy to restore heart muscle and an unusual reptile museum in Ecuador.
Active Exploring like a Pigeon: Reinforcing Spatial Reasoning via Agentic Vision-Language Models
Announce Type: new Abstract: Enabling Vision-Language Models (VLMs) to perform spatial reasoning remains challenging. Existing approaches treat VLMs as passive observers, which is difficult for real-world applications. Moreover, reinforcement learning methods rely on sparse rewards, limiting their effectiveness for complex reasoning tasks.
