Chemical Apple Dip By Science Service
New York State Agricultural Experiment Station has developed a home method to firm apples for pies canning or freezing. Calcium lactate proved best after testing various calcium salts. Two ounces per gallon of water treats at least half a bushel of sliced apples, but only works on fruit not too soft or overripe.

Nature Ramblings on Ants and Their Ancient Ways
Ant fossils show ants lived in large, organized communities at least thirty million years ago with caste division and labor. Ants can lift 400 times their weight, and colonies include males, females, and sterile workers. winged ants mate in nuptial flights as warm, windless days arrive.
The Nuptial Flight of Ant Colonies
A 1950 Science Service note explains ant nuptial flights when clouds of winged males and females swarm. Males die soon after mating while fertilized females seek homes underground or in established colonies using stored sperm for life. If you see winged ants at a picnic day, handle them gently as their brief honeymoon ends quickly.

Power Plants Will Be Gas Turbines Not Jet Engines
The article argues turbo props, using gas turbine engines to drive standard propellers, will boost civil airliner speeds beyond current piston engines while saving fuel and using existing runways. It notes jets may remain for very high speeds, but turbo props suit most transport needs, with U.S. and British efforts, and projects like Convair, Boeing Stratocruiser, and Navy developments shaping the shift.

Raincoated Scientist Hunts Ouachita Salamander
In the Ouachita Mountains researchers led by Clifton H. Pope seek the rainbow colored Plethodon ouachitae. The elusive salamander surfaces mainly during heavy rain, fading quickly after capture, complicating field collection and study of its evolution. Previous Appalachian hunting efforts failed to find relatives.
