  1. One heartbeat of a hummingbird in flight 48 ms

    Hummingbird hearts can hit 1,260 beats per minute in flight, then crash to about 50 at night when the bird enters a hibernation-like torpor.

  2. a-ha's 'Take On Me' 3.8 min

    The Norwegian band recorded it three times before it became a hit — the famous pencil-sketch video took 16 weeks of rotoscoping by hand.

  3. Holi, the Hindu festival of colours 2 days

    It opens with the Holika bonfire at night and erupts into colour-throwing the next day — the powders were traditionally made from flowers and herbs.

    Foals can stand within an hour of birth and gallop within a day — a survival feature for a prey animal born on open grassland.

  5. The Siege of Leningrad in World War II 2.4 years

    Through the blockade, scientists at the city's seed bank starved to death rather than eat their collection of edible seeds and potatoes.
