Infants more vulnerable to serious brain injury from falling than previously thought
... .25-inch-thick carpet padding, and a 4-inch-thick foam
pad, simulating a crib mattress. Volunteers also shook the doll vigorously and struck its head against each of the three surfaces. The 5-foot-fall onto concrete produced enough force to cause serious brain injury, the researchers found. But intentio...
UCR scientists modify existing chemical scrubber to environmentally friendly, all-natural filter
.... The UC Riverside researchers packed polyurethane foam
cubes inoculated with hydrogen sulfide-degrading bacteria into the OCSD scrubber. They also replaced the existing liquid pump with a smaller one, disconnected the chemical supply system, and modified the control systems. Emission of objectionable o...
A global 'catastrophe' -- coal fires threaten environment, human health
...t," a mixture of sand, cement, fly ash, water, and foam

Bone strength probed by scientists
...ientists made small indentations in bone, and like foam
rubber that is pressed down, discovered that the bone returns to its original shape. They found that this takes a stiffer force probe, or more force, to indent a bone than to stretch a collagen molecule. "The surface can recover back to its original...
