Gates, who is providing three grants via the Bill & Melinda Gates Foundation, said it was a "disgrace" that the world had allowed malaria deaths to double in the last 20 years, when so much could be done to prevent the disease.

A disgrace indeed. There's more money in ADHD research, and the medicine used to fight malaria, which kills 1.3 million annually worldwide, has pretty much been unchanged since the 17th century.
