New Gadgets And Innovations In Everyday Tech
Interchangeable frames for Weglasses allow matching lenses to different frames via notched lock joints. Steel and tin bulb containers guard Photoflash bulbs from radar-induced ignition during air transport. A safety valve tire core auto-regulates pressure to prevent blowouts. A compact key ring with flashlight aids keyhole finding. A five-foot floor-waxer carries a gallon of liquid wax with a flush control. A neck cradle shampoo tray suctions to sinks. Wool faced rugs use a six color rotary press for color and design. Synthetic rubber coated mattress covers resist tearing and sterilization.

May-apple flowers bloom under broad leaves in woodlands
May-apple blooms nod among broad twin leaves across woodlands this month. The small pulpy fruits are enjoyed by children but lack appeal for refined tastes. Podophyllum is the botanical name meaning foot and evokes the leaf’s webbed-foot resemblance.
Penguins Parade at National Zoo Show Off Imperial Dignity
The Washington National Zoo houses emperor penguins gathered from a five month Antarctic expedition by Navy ice-breakers Edisto and Burton Island. Malcolm Davis, head of the bird house and famed as the world’s Number One penguineer, oversees care as fish finally arrive for the birds during a coolly dramatic procession and parade in their glassed enclosure.

Fish Bite Reasons and Penguin Hunts In Antarctic Trip
A scientist explains fish biting hinges on hunger or anger, noting temperature and spawning affect appetite, while penguin hunting aboard the Edisto uses helicopters for rapid pursuit and nets for capture. The piece also covers penguin life, shipping challenges, and early experiments with carrier pigeons in Antarctica by Mr. Davis.
Junior Scientists Demonstrate Oxygen from Peroxide
A science club experiment shows oxygen release from hydrogen peroxide using simple glassware and a corked tube setup. With prepared inverted bottles, steel wool burns in the oxygen and flames flare when exposed to the gas, illustrating that oxygen supports combustion rather than burning itself.
Radio Aid for Mine Rescue Studied By Science Service
Science Service reports that low frequency radio communications show promise for direct link between trapped miners and rescue crews. The Bureau of Mines notes advantages over walkie talkies and high frequency systems, with a French WWI ground transmission method offering Morse only. A modified system used by some firms relies on trolley wires and rails but remains unreliable in certain emergencies.

Chromosome Increase Boosts Plant Growth and Drought Survival
German botanist Karl Pirschle reports that doubling chromosome numbers in lilies and Crassula enhances size and water storage, aiding drought tolerance. Austrian botanist Gertrud Jaehn notes plants often multiply chromosome numbers in specific tissues while others remain unchanged.

Nazis Built an Extensive Study of Victims in Poland
Nazi troops in Poland conducted a large scale study of physical characteristics of people, creating over 2,000 records with photos, measurements, hair samples, fingerprints, and medical histories. The records, stored at the Smithsonian, may later be returned to Poland for legitimate scholarly use.
