Flame retardants found on supermarket shelves
...rdant additives in electronics and in polyurethane foam used for carpet padding, mattresses, chairs, sofas and other furniture have been detected in humans across the globe, but scientists are not certain how they are getting there.

... .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.

...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.
