The holes in honeycombs don't actually start out as hexagons. Bees create circular tubes staggered with one another. The heat formed by the activity of the bees softens the wax, which connects the gaps between the holes. Then the wax hardens into the the most energy efficient shape, the hexagon. discovermagazine.com/plan…

The Blue Peacock project wanted to store nuclear mines in Germany. If the Soviets invaded, the bombs would be detonated. One technical problem was that a mine's electronics could fail because of the cold. One proposed fix was to use live chickens, as their body heat would prevent this. en.wikipedia.org/wiki/Chi…

Many higher end, larger camera lenses are white instead of black due to issues caused by temperature fluctuations. As a lens heats in sunlight, it expands, affecting focus of the glass elements. This is particularly problematic for larger lenses. The white color helps reflect light/heat. petapixel.com/2016/02/19/…
