Do animals possess an internal compass, and how does human activity disrupt it?
In short: Many animals navigate the world using an innate magnetic sense. This video explores the mechanics behind this biological ability and explains how modern human activity is interfering with it, while detailing the scientific methods used to measure these subtle interactions.
The National Physical Laboratory (NPL) investigates sensory biology to understand how living organisms perceive magnetic fields. Principal Scientist Alex Jones leads research into how specific biomolecules react to these fields, a field of study that informs the creation of advanced measurement techniques like non-linear imaging and quantum technologies.
By studying how biological systems interact with magnetic environments, scientists aim to develop new diagnostic and imaging tools. However, this research also highlights a growing concern: human-generated activity is increasingly impacting the natural magnetic navigation systems that animals rely on for survival.
