...years that medical researchers have been studying and describing the virus of poliomyelitis, they had never seen the critter. Now, two teams of investigators working independently have isolated the virus, looked at it long and hard under the electron microscope, photographed it and measured it. It turns out to be a spherical particle almost exactly a millionth of an inch in diameter. Magnified tens of thousands of times against a plastic screen, the virus particles look like tennis balls on an asphalt court...
...reason for the long delay in completely isolating the virus was the difficulty of separating it from the substances in which it grows. Until recently, a relatively "pure" preparation was only 1% virus and 99% "gunk...
...biochemists at the University of California, Drs. Howard L. Bachrach and Carleton E. Schwerdt, did it the hard way.'They grew polio virus of the Type II or Lansing strain in the nerve tissues of rats, and got the concentration up to about 10%. This preparation contained particles of two sizes, some a millionth of an inch in diameter, the others less than half as big. The researchers separated the two kinds in an ultracentrifuge. then they injected the materials into different groups of rats. Only the animals that received the millionth-of-an-inch particles caught polio. That...
Laid up with a virus infection at his winter home in Pinehurst. N.C.. General of the Armies George Catlett Marshall, 72, got some news better than any medicine. After 52 years of Nobel awards, five Norwegian politicians picked Old Soldier Marshall as the first professional military man ever to receive the Nobel Peace Prize.

At week's end Marshall flew...
