Most islands don’t move around much. But for more than two decades, scientists and others operated from one that did. Known as T-3, the kidney-shaped island was seven miles long. It drifted close to the north pole. And eventually, it melted away. That’s because the island was made of ice -- it was a giant iceberg.
T-3 was discovered after World War II, when the military was sending airplanes across the Arctic Ocean to keep an eye on the Soviet Union. In 1952, the Pentagon built a station on the island to record the weather.
If you receive a slice of pie but learn you will get a whole pie to yourself if you can wait ten minutes, could you wait? Scientists previously thought only humans and other apes could delay gratification. Then they learned crows and parrots could wait for better rewards too. It turns out cuttlefish, a relative of octopuses and squid, have the same ability to forgo one treat to wait for a more desirable one.
