(Phys.org)—A team of researchers with the National Centre for Biological Sciences in India has found that the visual processing capabilities of the planarian flatworm are much more complex than has been thought. In their ...
Biologists at Tufts University have succeeded in inducing one species of flatworm to grow heads and brains characteristic of another species of flatworm without altering genomic sequence. The work reveals physiological circuits ...
