A new study has uncovered a hidden step that helps the deadliest malaria parasite survive and multiply inside the human body. Researchers studying Plasmodium falciparum found that the parasite relies on a brief but essential stage, nicknamed the "Crown" stage, to make sure a crucial internal structure is passed on correctly when it divides. The discovery offers a fresh look at how the parasite reproduces and could point to new ways to stop malaria by disrupting this process.
