Silkworms in a Japanese lab are busy spinning silks with a colorful glow.
Biosciencia's insight:

Malcolm Fraser, a molecular biologist at the University of Notre Dame, suggests that while the fluorescent silks are interesting, they’d be even better, and more practical, if the colors were more robust. In 2011, Fraser and his colleagues engineered a silkworm that spun spider silk. “The coloration conferred by these fluorescent protein sequences is not strong enough to impart a significant coloration in visible light,” he said. “Coloration using dyes is much more versatile in terms of the color palette, and certainly more practical in terms of creating fabrics.

Eel popular in sushi offers advances in bioimaging.
Nature News doi: 10.1038/nature.2013.13190
Biosciencia's insight:

The Japanese freshwater eel (Anguilla japonica) has more to offer biologists than a tasty sushi snack. Its muscle fibres produce the first fluorescent protein identified in a vertebrate, researchers report inCell.
