Dr Robbie Waugh, the research leader, said, "We will be using experimental techniques that have been developed in human and other plant genetic ...

New technique could alter field of mouse genetics

... has been used experimentally as a tool to control pest insects from moths to flies and mosquitoes. The transposon has also seen heavy use in the genetic workhorse, Drosophila, where it is perhaps second only to the P element, whose talent to engineer changes in the fly's genome was co-discovered by Sprad...

Bugs, even 'bad' ones, can be educationally beneficial, new book says

... 20 different types of pests. He includes how each pest is destructive to humans, how it sustains itself through feeding, reproduction and avoiding predators, and the various methods that people use to get rid of pests. The book is written for a general audience. "Many basic biological concepts such as e...
