Researchers have found that a substance used in toothpaste could be developed to fight drug-resistant forms of the disease malaria. The researchers say the finding came from a study involving a robot scientist. They said it was programmed with Artificial Intelligence, the ability to copy human behavior and make decisions. Scientists from Britain’s Cambridge University reported on the robot and their findings in the journal Scientific Reports. The scientists identified the common ingredient in toothpaste as triclosan. They said it showed the ability to stop malaria infections both in the liver and in the blood. Malaria kills around 5 million people every year. The majority of them are children in the poorest parts of Africa.
