From Washington Post:
“We think they are using quantum mechanics to navigate,” said Daniel Kattnig, a researcher in the chemistry department at Oxford University. Kattnig works in a lab that studies radical pairs — a phenomenon in which atoms acquire extra electrons that are “entangled” with one another, each affecting the other’s motion even though they’re separated by space. It’s a field of science that’s difficult to understand under the best of circumstances; imagine trying to figure out it out with a bird brain.
But according to an increasingly popular theory, birds and other animals use a radical pair-based compass to “see” the Earth’s magnetic field, allowing them to undertake great migrations and daring rescues without getting lost. It’s still unproven, but Kattnig and his colleagues just verified a key component: In a study in the New Journal of Physics on Thursday, they report that the timing of these subatomic interactions makes them a good candidate to explain avian navigation.More.
It’s all accidental. Please move on.
