Silkworms Made to Spin Fluorescent Colored Silk

...a reprint from CraftMagazine:

Silk worms that produce vibrantly coloured and luminescent silks have been created by scientists in Singapore. The resulting fibre offers a cheap way to circumvent the dying process and may even have medical applications.

By feeding silkworms a mulberry mixture containing fluorescent dye, Natalia's team was able to harvest brightly coloured silk that is structurally unaffected, but which also has luminescent, or glowing, properties. The dye molecules are ingrained within the silk filaments to create permanent colour.
