New Gadgets And Materials Highlight Science Service Bulletin
New substitutes for cassia nutmeg and cinnamon mimic natural oils in odor and strength. Plastic lenses in portable spotlights transmit six percent of light with a four pound unit powered by a six volt battery. Powerline talkie units enable inter office and inter plant communication without new wiring. Plastic tubing replaces rubber in creameries and brewers, offering equal strength and heat resistance with visible leaks. An automatic water level recorder aids flood prediction and drainage planning. Plastic sheets simplify polishing buttons and a gauge shows tire load wear to adjust air pressure. A shell based egg scrambling device uses a dual spring needle. For more, request Gadget Bulletin 161 from Science Service.
Fish Need Air For Survival In Water Bodies
The passage explains fish die if exposed to air and rely on dissolved oxygen in water for blood. It notes plants need dissolved oxygen and carbon dioxide for growth, and pollution lowers oxygen by bacterial and chemical action while stunting aquatic plant growth, reducing fish food.
Germ Free Monkey Teddy Pioneers New Research Field
Teddy the germ free monkey at Notre Dame lives in sterile isolation yet now begins to acquire a normal internal flora. Researchers led by Prof. James A. Reyniers test whether harmless germs are needed for health and study methods for raising germ free animals for scientific use.

Junior Scientist Tests Heat Absorption With Cloth Color
The Science Service method shows a child friendly experiment using wax pinned cloth samples on a tumbler to reveal which color absorbs heat by the order pins fall. It explains dark colors heat faster and guides choosing outfits for hot sunny days. It also notes Teddy the animal's agoraphobia and adjustment to a wider world.

Plywood in Aircraft Will Help But Not Replace All Materials
James J. Dunne of United States Plywood Corp warns that plywood aircraft will fill selective postwar needs. Plastic plywood does not exist and aluminum shortages drove reliance on wood. He urges coordinated design data, plant distribution, and a clearing house to match capable firms with welding and bonding work.

Canada studies Russian dandelion roots for rubber supply
Canada is testing kok with dandelion roots as a potential rubber source. Since 1942 eight stations planted seeds, yielding about 5,100 pounds of roots per acre on average, with Kentville Nova Scotia leading at 8,100 pounds. Rubber content ranged from 2 to 7 percent.
