Description: An example of a planarian, which is a type of flatworm that features regularly in biological research thanks to its incredible ability to regenerate an entire new worm from each fragment when cut up into little pieces. They are effectively immortal and can endure extended periods of not eating by 'de-growing', making them very easy to care for. Capitalising on previous ESA-supported efforts, an ESA-supported research co-sponsorship study will explore the effects on the cells of these flatworms being exposed to different levels of gravity for prolonged periods.
