Persimmon Nostalgia and Disease Hit Native Trees
Nostalgic memories link to frost ripened persimmons, but frost is not needed. Persimmon orchards have declined after a fungus wiped out native trees. Cultivated Oriental persimmons resist disease and may dominate in coming years.
Home Heaters Promise Fuel and Space Savings
Postwar heating engineers outline new furnaces and stoves that maximize fuel use, cut space needs, and improve efficiency. The designs include compact anthracite units with continuous water jackets, a 100 pound coal stove with near smokeless burn, liquid fuel furnaces for planes adaptable to homes, and infrared lamps as supplementary heat. These systems aim for complete combustion, minimal outdoor heat loss, and easier maintenance.
Junior Scientists Make Moth Balls Dance In Experiments
A family science note explains how moth balls heated in a spoon with naphthalene gas bubbles rise and sink in carbonated water. It details safe handling, flame risks, and how to create sparkling soot coatings on surfaces for recording motion with simple items like a feather or hair.
