Stem Cells Exhibit Unusual Property
Stem cells demonstrate a bizarre property never before seen at a cellular level, according to a study published today by scientists at the Univ. of Cambridge. The property, known as auxeticity, is one that may have application as wide-ranging as soundproofing, super-absorbent sponges and bulletproof vests.
Most materials when stretched will contract. For example, if one pulls on an elastic band, the elastic itself will get thinner. The opposite is also true: squeeze a material and it will expand – if one squeezes a tennis ball between both hands, the circumference around the ball gets larger. However, material scientists have begun to explore auxeticity, an unusual property that has the opposite effect – squeeze it and it will contract, stretch it and it will expand. This means that auxetic materials act as excellent shock absorbers or sponges, a fact that is being explored for various uses.
