Ancient bristle worm jaws redefine metal in biology as a new class of bio-metals

Microscopic tests of Perinereis cultrifera jaws show ion‑coordinated proteins that harden toward the tips and display metal‑like, size‑dependent elasticity, supporting a new category called bio-metals that blend polymeric structure with metal‑like hardness; researchers used nanoindentation and manifold micromechanics to define bio-metals by hardness, strain behavior, and ion‑protein structure and plan to study more species and potential genetic links to material design.

Self-Replicating Creature with 3D-Printing Abilities

A study reveals that bristle worms can produce their body parts through a process similar to 3D printing, with their cells acting like tiny printers depositing chitin to form structures like bristles and teeth, which could inspire new medical materials and regenerative therapies.

Nightmarish 'Demon Fire' Worms Unearthed

Scientists have discovered a new genus of glow-in-the-dark worms they call ‘demon fire’ worms, which are part of a family of worms known as bristle worms. The three newfound species are found in the shallow waters of Japanese rivers and streams. Researchers want to determine how the glow-in-the-dark worms create their bioluminescent appearance and then use that to develop a man-made type of bioluminescence. Bristle worms like these new demon fire worms have existed since the Cambrian period, over 505 million years ago.

Nightmarish 'Demon Fire' Worms Unearthed

Scientists have discovered a new genus of glow-in-the-dark worms they call ‘demon fire’ worms, which resemble the ancient demons of Japanese folklore. The three newfound species, named Polycirrus onibi, Polycirrus aoandon, and Polycirrus ikeguchii, are found in the shallow waters of Japanese rivers and streams. Researchers want to determine how the glow-in-the-dark worms create their bioluminescent appearance and then use that to develop a man-made type of bioluminescence.
