A Wriggly Worm Wriggling in your Behind

“ Scientists are developing a new way of carrying out internal examinations on patients – based on a wriggling worm.

In an endoscopy, a long flexible tube is fed into the body. It can be very uncomfortable.

But a team from the Scuola Superiore Sant’Anna, Pisa, found the ragworm, which lives in seashores, could offer a model for a more comfortable test.

They say their device would be able to “pull” itself along, rather than having to be forced into the body.

The team have developed a prototype device, named the Bioloch Ist, which imitates the undulating motion of the ragworm, also known as the paddleworm.”

This is interesting, but it still bothers me a little.
