Researchers zero in on malaria’s lethal skill
PRINCETON (US)—The parasite that causes malaria has a very deadly talent. By switching off an important amino acid in its quest to invade the human body, the parasite may trigger a more critical and lethal phase of the disease. The findings could pave the way to more effective Malaria treatments. (more…)
