For decades, scientists pursued one goal: a vaccine that could prevent the disease. But malaria is caused by a complex parasite, making vaccine development far more challenging than for most infectious diseases. One scientist dedicated his career to this challenge. Sir Adrian Hill of the University of Oxford witnessed children dying from malaria in Gambia in the late 1980s and set out to develop a vaccine that could save lives wher...

In sub-Saharan Africa, mothers often carry their babies on their backs in colorful cotton wraps called lesu. Could treating these wraps with insecticide help prevent malaria? Dr. Ross Boyce discusses a groundbreaking study in Uganda showing that permethrin-treated wraps significantly reduce malaria in infants – and further, what this could mean for protecting the youngest and most vulnerable children from this of...

Too much can kill the mosquito — too little can also kill it. But the right amount can strengthen the mosquito's defenses and stop malaria transmission. Today, the Goldilocks dose. Emma Camacho shares how a natural compound called L-DOPA strengthens mosquitoes' defenses at just the right concentration, revealing a new way to block malaria transmission.

How next-generation bed nets could stop malaria by killing the parasites inside mosquitoes, not just the mosquitoes themselves.
Transcript
Bed nets have long been a cornerstone of vector control. Coated with insecticide, they serve a dual purpose: preventing bites and killing mosquitoes. But what if those nets could do more – not only kill the mosquitoes, but for those they don't kill be...
