Parasites are organisms that live in or on a host organism and obtain nutrients at the host’s expense, forming a specialized ecological and evolutionary interaction characterized by dependence and often high host specificity. They encompass diverse taxa, including protozoa, helminths, arthropods, fungi, and some plants, and exhibit complex life cycles that may involve multiple hosts and vectors. Research topics on parasites address host–parasite coevolution, immune evasion strategies, transmission dynamics, virulence evolution, and the population genetics and genomics of parasite species, as well as their roles in ecosystems, disease emergence, and the modulation of host physiology and behavior.
The world's first lab-based tick feeding system for bush ticks, developed by researchers at the University of Melbourne, has transformed the study of ticks and how they transmit disease. The novel, host-free technology reduces ...

Humans tend to fear bed bugs, and rightly so. The bloodsuckers are tough to get rid of once they've entered a home. But new research has, for the first time, identified one thing the bugs seem to fear—water and wet surfaces.
