Odd Fish Eels Migrate Vast Distances to Breed
The article says adult eels abandon streams to spawn in the middle North Atlantic where they die. Their young elvers swim back unguided. European freshwater eels make a similar migration to an ocean-bottom area south of the American breeding ground. The two species apparently never mix.

How to Get Rid of Flies with DDT and Pyrethrum
A guide to indoor fly control uses an aerosol mist bomb containing pyrethrum and DDT for quick knockdown. It advises closing openings, spraying ceilings and roosting areas with a 5 percent DDT in odorless kerosene, and applying to screens and building exteriors.
Junior Scientists Build Fly Traps From Screen Scraps
Home made traps catch many houseflies using discarded screen parts. Builders form two wood disks as a base and top, wrap screen into a tapered cylinder and cone, secure seams, and add a bait dish. Set traps on sunny sides to attract flies and empty when crowded.

Scientific Sizing to Improve Boys Clothing Fit Across Sizes
Scientists and manufacturers will use a new size system based on height to standardize boys clothing from underwear to coats. A study of 68 000 boys showed height dominates body measurements, with size gaps narrowing as kids grow. A three measurement size dictionary is planned for future labeling.

Shell Collecting for Summer Fun and Simple Caring
Shells and other beach trophies offer easy collecting for a summer hobby. Use small boxes or compartments to house delicate finds and nest tiniest shells in pillboxes. Group shells by shape, focus on two main mollusk classes, and explore inland sources for diverse specimens.
Glass with iron oxides blocks harmful sun rays
Libbey-Owens-Ford scientists add ferric oxides to melted glass to cut heat and fading in fabrics and drugs. A ferrous oxide version blocks about 90 percent of heat rays. Both types used in a railroad car window, with a dehydrated air space to prevent fogging and keep travelers with a clear view.
