The Fly As A Formidable Tiny Invader In 1947
A Science Service overview explains the common housefly as a superb flying machine with a single pair of wings and balancer knobs. It details six legs with sticky pads, bristles, and germ transfer, plus a tube like tongue for liquefying food. It notes the fly cannot bite, except for bloodsucking species, and highlights its compound eyes and wide field of vision enabling ceiling roosting and rapid escape.

How to Get Rid of Flies With DDT Sprays
The article describes two indoor fly control methods using DDT. An aerosol mist bomb containing pyrethrum and DDT provides quick knockdown, with the room sealed for about 30 minutes after spraying. A 5 percent DDT in odorless kerosene solution is applied to ceilings and roosting areas and on screens, leaving a lasting residue that kills flies within an hour.
Homemade fly traps from discarded screening materials
Junior scientists describe building simple fly traps using reused screen and wood disks. Two disks form a tapered cage with a cone of screen, bait such as molasses mix or fruit waste, and a base to rest on nails. Set traps where flies gather and maintain bait. discharge when crowded.

Scientific sizing to improve fit for boys clothing
National standards researchers mapping boy anatomy to create a unified sizing system. Height governs most measurements, with size changes tied to inch differences as kids grow. A three measurement size dictionary will guide manufacturers, while women’s sizing poses similar challenges due to girth alongside height.

Shell Collecting For Summer Fun And Easy Care
Shell collecting makes a summer hobby. Gather shells with simple boxes, nest tiny ones in pillboxes, and sort by shape rather than color. Snails and bivalves dominate early collections, with shells from trees, streams, and buried finds offering varied ages and forms.
Glass With Iron Oxides Cuts Sun Rays
Libbey-Owens-Ford scientists add ferric oxides to melted glass to block heat producing rays. A ferrous oxide glass excludes 90 percent of sun heat affecting drugs and chemicals in manufacture. Used in a railroad car window, the dehydrated air space prevents fogging for clear views.
