Abstract: The program opens with a film visit to the National Institutes of Health labs in Bethesda MD Dr Tomlinson explains the life cycle of schistosomes via snails to humans Dr Wright describes the characteristics of the disease and shows films of victims of the parasite He also explains how US troops fighting in the South Pacific could bathe in infested streams and bring the parasite to the US unless they use chemical repellants on their clothing and body Dr Cram describes her teams search for a US snail that could serve as a host for schistosomiasis The NIH schistosomiasis snail study collection from around the world is displayed Dr Nolan describes her search for a safe chemical compound to pour into waterways to kill snails on a large scale and she demonstrates how it works

Abstract: Lynn Poole shows an artists rendition of tic douloureux or trigeminal neuralgia and Dr Smith describes this pain of the fifth cranial nerve A sketch of the head shows the three nerve divisions in the face and an electrical model traces the nerves pain transmittal to the brain The causes of this affliction are unknown and the occurrences unpredictable although the painful attacks often occur from eating talking or touching the face This is a disease of advancing years and Dr Smith interviews an elderly patient Mrs White who attempts to describe her symptoms until orifacial pain overcomes her As early as the 1500s treatments included surgery to cut the nerve This is still performed and Dr Smith interviews Mrs Frank who received such surgery and now has no sensation of pain at all in one side of her face as evidenced by the doctor sticking a pin into her cheek Other remedies now include chemically damaging the nerve by injecting it with alcohol or novocaine cutting the fiber track

Abstract: Dr Waring vice president of the Davison Chemical Co in Baltimore MD defines a catalyst as a substance that when added to a chemical reaction either speeds it up or causes it to take place at a lower temperature He offers the example of a sugar cube held in a flame which will not burn unless potash from a cigarette ash is added Commercial applications of catalysis include petroleum refining converting distilled crude oil into transportation fuels and other petroleumbased products Dr Waring shows a model of the catalyst cracker and describes the cracking process in petroleum refining An animated film shows what takes place in the reforming part of the process in which the molecular structure of the petroleum is changed to alter its combustion characteristics and thus alleviate knocking in automobile engines Platinum is the catalyst in the reforming process Dr Waring notes that the silica gel developed and patented in 1919 by Johns Hopkins scientist D Walter A Patrick is the base for many catalytic materials Other catalyst include vinyls which are used to make plastics

Abstract: Dr Strieby of American Telephone and Telegraph Co demonstrates Bell Labs recent invention of a solar battery capable of producing sufficient electric voltage from any light source to operate a telephone However most telephone services have large power plants and storage batteries which function when no light is available so there is no reason to substitute a solar battery Dr Strieby next demonstrates a personalized telephone prototype like Dick Traceys which functions like a miniFM broadcasting station using transistors activated by a solar battery This is only experimental and shortrange because of the length of antenna required to transmit beyond a few hundred feet Dr Strieby then explains how a solar battery is built using silicon from DuPont that is purified through a diagrammed process Ultimately with the addition of arsenic and boron gas the thin sheets of silicon create a positivenegative juncture that allows light to become electricity

Abstract: In this last program of the threepart series produced with the cooperation of the Atomic Energy Commission AEC on peacetime uses of atomic energy Lynn Poole shows a model of the nations first commercial nuclear reactor the Shipping port power plant in Pennsylvania He lists the products of this nuclear reactor as a result of splitting uranium235 heat fissionable materials fission products and atomic radiation Dr Manov of the AEC explains radioactive isotopes such as carbon14 and why irons or other household appliances can not be atomic powered He describes the ways radioisotopes can be used in industry for such purposes as checking metal castings for flaws gauging thicknesses measuring the wear and life of a cutting tool tracing oil flow in pipelines and applying the process of handling dangerous materials to other purposes A film shows the application of radioisotope tracers to improve milk production in cows eggshell thickness in chickens and fertilizer use in plants

Abstract: Dr Phelps explains that cerebral palsy is an injury to the portion of the brain dealing with the control of muscles for the arms legs and speech and generally does not affect ones intelligence Because the parts of the brain affected cortex cerebellum and basal ganglia do not regenerate surrounding brain cells must be trained to carry out the missing functions This is done through physical therapy Dr Phelps describes the activities of therapists at the Childrens Rehabilitation Institute working with children on reciprocal exercise patterns and training them on the stabilizer crutches and parallel bars Mr Schwartz works with children on blowing exercises speech and auditory therapy and speech training using a mirror Children demonstrate other exercises including grasping and releasing blocks placing pegs in holes as part of a game practicing dressing skills on a doll and typing on an electric typewriter Dr Phelps offers hope to the afflicted giving the example of Betty Lou Driver who learned how to walk at the Institute and now as an adult works there helping other children

Abstract: Part title from label This program is the first in a threepart series on peacetime uses of atomic energy A brief animated film reviews such concepts as neutrons and protons in a nucleus surrounded by electrons There are 92 kinds of naturally occurring atoms and changes can only be made to an atom by altering its nucleus When the nucleus is split it gives off energy Mr Strauss the chairman of the Atomic Energy Commission AEC cites President Eisenhowers 1953 Atoms for Peace speech to the United Nations in which he suggests a world pool of atomic materials for peaceful uses such as commercial electrical power Dr Hafstad Director of the Reactor Development Division of AEC discusses the costs and problems of harnessing atomic power He points out that although our coal and oil supplies are dwindling and uranium supplies are vast the cost of generating power from the atom is currently prohibitive However he predicts that within the next five to fifteen years as nuclear power is developed its costs will fall

Abstract: In this second program in a threepart series on peacetime uses of atomic energy Lynn Poole demonstrates how radioactive iodine has been collected in a womans thyroid for diagnosing goiter An animated film shows the differences in size shape and stability of various atoms the unstable ones being labelled radioactive isotopes Dr Bugher of the Atomic Energy Commission claims that the use of nuclear energy has advanced medicine by 25 years For example radioactive isotopes can be used to study the actual functioning and behavior of plants and animals to trace and diagnose diseases such as thyroid problems and to treat and cure diseases such as polycythemia a form of cancer He also demonstrates a thulium xray unit and narrates a short film showing cobalt60 radiation of a patient with cancer Gamma radiation is compact reliable and intense Dr Bugher notes that cesium separated from the waste of atomic reactors is a useful source of radiation commercial electrical power Dr Hafstad Director of the Reactor Development Division of AEC discusses the costs and problems of harnessing atomic power He points out that although our coal and oil supplies are dwindling and uranium supplies are vast the cost of generating power from the atom is currently prohibitive However he predicts that within the next five to fifteen years as nuclear power is developed its costs will fall
