“Importantly, and enabled by the experimental virtues of the worm, the research shows this is dependent on the hormone nematocin, the ancient nematode version of a human hormone called oxytocin. These hormones are known to regulate sociability and have been called the ‘love hormone’.

Do nematodes die in winter?

Which STD is caused by nematode?
