Entomologists discover first instance of intact neurons without nucleus - in fairy wasps
Fairy wasps are really tiny; so tiny, they can barely be seen with the naked eye. They’re so tiny that they’re the smallest organism when shown on a slide alongside an amoeba and a Paramecium. And because of this, ...
How the worm knows where its nose is
For decades, scientists have studied Caenorhabditis elegans tiny, transparent worms to glean clues about how neurons develop and function. A new Harvard study suggests that the worms' nervous system is much m ...
