When worms stick together and swim on thin water, what happens and why does it matter?
Nematodes, microscopic worms, are making engineers look twice at their ability to exhibit the "Cheerios effect" when they move in a collective motion.

Male worms plug females after copulation as a form of 'gift', rather than to prevent them from mating again, as had previously been thought. Researchers writing in BioMed Central's open access journal Frontiers in Zoology ...

Knocking genes out of action allows researchers to learn what genes do by seeing what goes wrong without them. University of Utah biologists pioneered the field. Mario Capecchi won a Nobel Prize for developing knockout mice. ...

Microscopic nematode worms can be a potent organic insecticide, killing crop-raiding bugs without harming plants or beneficial insects and without environmental side effects of chemical. The problem is that when the worms ...
