Poliomyelitis, also known as infantile paralysis, is a viral infection of the intestinal tract that sometimes can attack the central nervous system and lead to severe muscular paralysis. After the 1916 outbreak, the United States averaged 21,000 paralytic cases per year. During the 1930-40s, both private and government research was accelerated to try to find a cure for this dreaded disease. The National Foundation of Infantile Paralysis, now the March of Dimes, was inaugurated by Franklin D. Roo

Why Abenomics Matters: Abenomics and the Japanese economy [Audio]
Speaker(s): Professor Motoshige Itoh | Editor's note: The question and answer session has been removed from this podcast. Japan is highly unusual in having experienced serious deflation in recent years, and Japan’s experience may be regarded as providing a good case study for other industrial countries suffering from inadequate capital investment and what has been termed ‘secular stagnation’. This lecture explains the nature of the ‘Abenomics’ introduced by Japan’s Prime Minister, Sh
10.4 Summary By biological evolution we mean that many of the organisms that inhabit the Earth today are different from those that inhabited it in the past. Natural selection is one of several processes that can bring about evolution, although it can also promote stability rather than change. It follows that natural selection is not the same thing as evolution. The four propositions underlying Darwin's theory of evolution through natural selection are: (1) more individuals are produced than ca

An Electronic Design Assistance Tool for Case Based Representation of Designs
In precedent based design, solutions to problems are developed by drawing from an understanding of landmark designs. Many of the key design operations in this mode are similar to the functionalities present in case based reasoning systems: case matching, case adapting, and case representation. It is clear that a rich case base, encoding all major product types in a design domain would be the centerpiece of such an approach. EDAT (Electronic Design Assistance Tool) is intended to assist in preced

The wobbly beam of the Vela pulsar
At the center of the Vela supernova remnant is a madly spinning neutron star. It spins *11 times per second*, which helps it whip up a magnetic field so fierce it can actually defy the gravity of the star, which is a billion times stronger than Earth's! All of this help it generate two beams of matter and energy that blast away from its poles. Recent observations of this beam show that it appears to be wobbly, making a corkscrew motion over a period of 120 days. This movie is made from 8 images

Secrets in the Salt
In this video segment adapted from NOVA scienceNOW, take a trip
to an underground salt deposit that formed 250 million years ago to
search for evidence of ancient life. Learn about the formation of the
salt deposit and observe as scientists drill into the salt walls to
retrieve samples. See liquids trapped within the salt that are millions
of years old, and hear from scientists who were stunned to find that
there were fibers of ancient cellulose inside.
