Researchers are making progress in controlling the malaria parasite as well as understanding the mosquitoes that carry them. Writing in the journal Science, a team of scientists tackles the question of why mosquitoes themselves often are parasite-free, even though the malaria parasite they carry reproduces rapidly within mammalian hosts. The answer, they think, may be due to an 'immune memory' formed early on in a mosquito's life. We'll find out more.
