Everyone knows what happens when a would-be suicide closes the garage door, runs a hose into his car from the tail pipe, and sits inside the car with the engine running. Carbon monoxide, in such heavy doses, is one of the deadliest of gases. It gets into the blood and starves the brain of vital oxygen. The victim turns red and usually dies. But doctors have been arguing for decades about the effects of small doses of monoxide poison over long periods. Only recently have they begun to collect evidence that such small doses may do permanent damage...

Most medical men believe that the body flushes out carbon monoxide quickly after a return to breathing pure air. The Yale neurologists say this may not always be true after repeated exposures, and certainly not for all people: the New Haven cop had a high blood level of monoxide 30 hours after exposure to the fumes. European experiments with lab animals confirm the growing suspicion that leaky stovepipes, rusted-out mufflers, and running a car for even a few minutes inside a garage may involve greater and more subtle dangers than doctors have realized...

Palmer also revealed that more efficient IBM cards will replace the onces now being used to sign books out of the library. The new cards will eliminate the need for carbon copies and will be put into use as soon as the supply of old cards is exhausted, sometime within the next week...

...sightings by Russian Astronomer Nikolai Kozyrev. Dr. Hall believes that the fierce heat of returning sunlight may have released gases from the lunar interior. At a Dallas conference on newly discovered astronomical objects last week, Nobel Chemist Dr. Harold Urey suggested that the gas may have contained carbon in the form of two-atom molecules that cannot exist on earth. If further evidence proves that the spots really do exist and are indeed caused by eruptions of gas from the moon's interior, they will present one more difficulty for would-be lunar explorers...

Everywhere archaeologists, armed with all the advantages of modern science, are extending the geography of history. Aerial cameras detect the faint outlines of long-demolished walls; delicate airborne magnetometers ferret out forgotten fortifications; measurements of minute bits of carbon establish accurate dates back beyond any written record. Mummies are submitted to autopsy for a knowledge of ancient diseases. Fossilized grains of pollen testify to the climate in which they grew. Reused writing materials, called palimpsests, are irradiated with ultraviolet light and reveal words that were erased thousands of years...
