New research published in PLOS Genetics shows that starving C. elegans (Caenorhabditis elegans) during the late larval stage of development when the worms are undergoing tissue growth and formation halts cellular activity at previously unknown checkpoints in their development. These findings show that nutrition is an important cue to signal whether or not the worms should…

Believe it or not, scientists at Albert Einstein College of Medicine in collaboration with Coronado Biosciences are intentionally infecting people who have autism with whipworms from pigs (Trichuris suis), although generally considered non-pathogenic to humans. For some individuals, an elevated inflammatory state contributes to repetitive and irritable behaviors associated with autism. Researchers have observed that…

A new species of velvet worm (Eoperipatus totoros) is the first to be described from Vietnam after its discovery in 2010. This 2.5 inch long worm is distinguished from other velvet worms by hairs with unique shapes that cover its body.  These animals are difficult to find and study because they are usually hiding in the moist soil…

Researchers Tal Shomrat and Michael Levin at Tufts University have found that planaria worms are able to quickly relearn lost skills after literally losing their heads.  The researchers trained the worms to find food in an environment with bright light and open space, both considered uncomfortable to the creatures. The time it took for worms to adjust to the environment…

  A recent article posted in the BBC News provided a good explanation of why scientists commonly study these organisms as models for human diseases and conditions. Model organisms are chosen because their physiology is similar to other animals, including humans, in addition to other reasons: Visit the BBC News to see why researchers most often use flies, fish, mice and worms…

Christmas Tree Worms

Here are some images of Christmas Tree worms (Spirobranchus giganteus), just in time for the holidays: These are tube-dwelling worms that live in coral reefs and use their spiral plumes for feeding and respiration.
