Small study reveals details of brain damage in COVID-19 patients

Massachusetts General Hospital researchers examined six patients using a specialized magnetic resonance technique and found that COVID-19 patients with neurological symptoms show some of the same metabolic disturbances in the brain as patients who have suffered oxygen deprivation from other causes.

How do geese know how to fly south for the winter?

Geese honk loudly and point their bills toward the sky when they're ready to start the migration. Here's how they know it's time, how they navigate and how they conserve energy on the grueling trip.
