Episode notes
School Teddy Lost After Stratosphere Ride
- Bradfield Bear rode a weather balloon to 27 kilometres and became detached during turbulence on descent.
- GPS suggested he may have landed near Reading, and the school appealed locally to find him.
Bears Preserve Bone During Hibernation
- Black bears hibernate up to seven months while maintaining bone strength and losing minimal muscle.
- Studying their physiology may reveal mechanisms to prevent astronaut bone and muscle loss in microgravity.
Muscle Shrinkage Without Functional Collapse
- Muscle fibres in hibernating Japanese black bears shrink ~26% but overall muscle function is largely retained.
- Bears preferentially lose fat while protecting muscle and bone, suggesting metabolic prioritization strategies.
