Silkworm's secret unraveled - Scientific American, August 28, 2003
Scientists have long envied the lowly silkworm's ability
to spin the strongest natural fiber known to man. Now they are
one step closer to understanding just how the creature manages
the feat. In a paper published today in the journal Nature,
researchers reveal that the key lies in the animal's ability
to carefully control the water content in its silk glands. The
findings should help improve future artificial silk-making techniques.
