An amputee flatworm grew two heads after spending five weeks aboard the International Space Station (ISS). Scientists are observing how microgravity affects cell regeneration in worms.
A recent study induced flatworms to grow the heads and brains of other species, by changing the cell communication and not by altering the genomic sequence. This, they say, could lead to birth-defect findings and other learnings.
As the researchers sequenced the flatworm's DNA, they observed which genes were activated for certain regenerative purposes which they believe will aid in future stem cell research.
It turns out that trematodes and other parasitic flatworms live in larger numbers in temperate regions, contrary to the global norm of greater biodiversity in warm temperatures.
Starfish have something in common with flatworms.
The highly invasive New Guinea flatworm, which spreads quickly and upsets the food chain, has been sighted in Florida.
