Vehicular Traffic Flow
The interaction of driver-car units on roads is now being studied by physical and mathematical methods. The results have already been used in the solution of traffic problems
Features
Polyribosomes
These collections of the particles called ribosomes appear to be the assembly lines on which the living cell manufactures protein molecules. How the assembly line works is just now becoming clear...
Quasi-Stellar Radio Sources
Neither stars nor galaxies, they are perhaps the brightest objects in the universe, and among the most distant. Until their puzzling spectra were recently decoded they were mistaken for nearby stars...
The Continuous Casting of Steel
This new method of steelmaking shapes and solidifies molten steel, readying it for the rolling mill in virtually one step. Developed in Europe, it is now being implemented in the U.S.
The Master Switch of Life
Studies of diving have led to the identification of the vertebrate animal's ultimate defense against asphyxia: a gross redistribution of the circulation that concentrates oxygen in the brain and heart...
Ancient Cumae
The first Greek colony in Italy was established here in the eighth century B.C. For the next 2,000 years Cumae played a unique role in the development of Western civilization
Magnetic Monopoles
They are fundamental particles that are predicted by conservation and symmetry principles but have not been detected. This apparent violation of physical theory has stimulated a new search for them...
The Aerial Migration of Insects
A few insects migrate seasonally over great distances rather like birds. Recently it has been learned that most other species also migrate by simply beating their wings while the wind carries them...
