When cooled, a superconducting disk drops its resistance and can “lock” magnetic fields. The result is a levitation show that looks almost frictionless over a magnetic track.
‘Water memory’ is more myth than science, but ice truly keeps archives. Layered snowfall traps traces of ancient air, letting us read past climates.
Certain ceramic coatings in spacecraft act as shields against extreme heat. Low thermal conductivity and high durability do what metal alone cannot.
Some bacteria can move electrons outside their cells and create a small electric current. Mud dwelling species can act like microscopic batteries.
The lifespan of dragonflies generally lasts 4 to 6 weeks, but some species can live for several months. Details in our article.
