Stainless Steel Wool Seen as Rat Barrier
The National Pest Control Association notes stainless steel wool forms an impervious stopper for rat entrances. Ordinary steel wool rusts and fails, but stainless steel wool resists corrosion and holds firm in small holes, while larger gaps can be sealed with cement mortar for a reinforced wall.

Armadillo Surprises Drivers On Texas Roads At Night
The armadillo relies on burrowing or ballooning to escape as predators. It crosses streams by walking on the bottom and swims with snout raised. Females give birth to quadruplets from a single fertilized egg. Texas highways prove deadly for the nocturnal traveler, as headlights startle the animal into a bounce that often ends with a collision.

Reinforced Concrete Favored for A Bomb Shelters and Bridges
As nations expand civil defense and Russia grows its stockpile, experts urge concrete as the best shield against blast heat and radiation. Government guidance favors well braced shells on steel or concrete frames, with plan 73402 for backyard shelters and tunnels connecting to basements. Prestressed concrete bridges, using high tension wires, showcase structural advances and notable designers Magnel and Freyssinet earned awards for pioneering work.

Insect Parasite Program Hosts On Red Scale Combat
Scientists at the University of California are rearing aphytis chrysamphali insects as biological control agents against red scale on grapefruit and potatoes. The program, run with the U.S. Agriculture Division of Biological Control, infects host fruits with scale, incubates in controlled insectaries, and harvests 15 000 to 18 000 parasites weekly. Grapefruit raised insects live twice as long as those fed on red scale potatoes, a fact not yet explained.
