Scientists grow head from another species on flatworms

Scientists at Tufts University in Medford, Massachusetts, have created a rather odd identity crisis for a handful of flatworms in their lab, the International Business Times reports. Using epigenetics triggers that change how the flatworms’ DNA is expressed (rather than changing the DNA sequence itself) the group created a worm that has the body of one species of flatworm and the head and brain of another. Researchers think the results may have implications in birth defects and regeneration.
