Robots are common in today’s world. They manufacture cars, work in space, explore oceans, clean up oil spills and investigate dangerous environments. And now, scientists at the University of Manchester are using a robot as a laboratory partner. The researchers there created the robot in 2009 and named it Adam. Despite the name, Adam does not look like a human. The robot is about the size of a car. Adam was built to do science and make discoveries. Ross King is the leader of the University of Manchester research team. He says the robot made a discovery about yeast, a substance used in science that models human cells. Adam made a scientific guess about the yeast. The robot then tested and confirmed the new scientific knowledge. Adam’s success as a scientist led to the creation of another robot scientist named Eve. Researchers developed Eve to design and test drugs for tropical and neglected diseases. These diseases kill and infect millions of people each year. Drug development is slow and costly. So the University of Manchester developed a low-cost test that shows whether or not a chemical is likely to be made into an effective medicine. Mr. King says that Eve is different because the robot learns as it tests different compounds. He says Eve is designed to ignore compounds that it thinks will not be good. Eve has discovered that a compound known to be effective against cancer might also be used to fight malaria and other tropical diseases.
