What is a CAT Scanner?
CAT stands for computerized axial tomography, a way of taking photographs of cross sections of diseased tissue 100 times more detailed than by the traditional X-ray method.
The inventor was Godfrey Hounsfield of Britain’s Electrical and Musical Industries, the company that first brought television into the home. The first CAT scanner in clinical use entered medical history in 1972 when it was used to diagnose a brain tumor in a woman patient in Wimbledon, England.
Hounsfield shared the Nobel Prize for physiology and medicine with American inventor Allan Cormack, who had independently worked on the principles of CAT scanning.

What birds can fly immediately after being hatched?
The mound builders, a family of birds inhabiting Australia and certain South Sea Islands, are unique in that the young are hatched fully feathered and are able to fly and live an independent life from the moment they emerge from the shell.
These birds are called megapodes because of their large feet. Most species lay their eggs in large mounds constructed of loose soil, leaves, grass, twigs, etc. The mounds are ten to twelve feet high and contain several truckloads of material.
After the eggs are deposited they are left to hatch out by the heat of the decaying vegetable matter. The brush turkeys are the most common of the mound builders. One species of megapodes lays its eggs in the sand on the seashore and leaves them to be hatched by the heat of the sun.
