With scientists unwilling to toss cats off buildings for experimental observation, science has been unable systematically to study the rate at which they live after crashing to the ground.
In a 1987 study of 132 cats brought to a New York City emergency veterinary clinic after falls from high-rise buildings, 90% of treated cats survived and only 37% needed emergency treatment to keep them alive. One that fell 32 stories onto concrete suffered only a chipped tooth and a collapsed lung and was released after 48 hours. From the moment they're in the air to the instant after they hit the ground, cats' bodies are built to survive high falls, scientists say.

Early next year, a tanker vessel owned by Maersk, the Danish transportation conglomerate, and a passenger ship owned by Viking Cruises will be outfitted with spinning cylinders on their decks. Mounted vertically and up to 10 stories tall, these “rotor sails” could slash fuel consumption up to 10%, saving transportation companies hundreds of thousands of dollars and cutting soot-causing carbon emissions by thousands of tons per trip.
