New weapon in malaria fight: a better bed net

A new kind of bed net that blocks mosquitoes' resistance to a common insecticide provides substantially improved protection against malaria, a major study has found. Malaria-carrying mosquitoes are rapidly evolving the ability to resist insecticides and the trait is spreading across Africa, putting millions of lives at risk.
To counter the threat, scientists have developed a novel bed net incorporating a chemical called piperonyl butoxide, which blocks the natural defense mechanisms of insects against the standard insecticide pyrethroid. The findings were published in The Lancet. Promising results with the new nets have already prompted the World Health Organization (WHO) to recommend their wider use.
