Shape of things to comeBreakthrough: Robot makes scientific discovery on its own

Published 3 April 2009

Researchers build a robot which used artificial intelligence to discover simple but new scientific knowledge about the genomics of the baker’s yeast Saccharomyces cerevisiae; not only this: the robot hypothesized that certain genes in baker’s yeast code for specific enzymes, which catalyze biochemical reactions in yeast — and then devised experiments to test these predictions, ran the experiments, interpreted the results, and repeated the cycle

Talk about a brave new world. Researchers from Cambridge and Aberystwyth Universities have created a robot that they believe is the first machine to have independently discovered new scientific knowledge. The robot, called Adam, has discovered simple but new scientific knowledge about the genomics of the baker’s yeast Saccharomyces cerevisiae, an organism that scientists use to model more complex life systems.

Using artificial intelligence, Adam hypothesized that certain genes in baker’s yeast code for specific enzymes, which catalyze biochemical reactions in yeast. The robot then devised experiments to test these predictions, ran the experiments, interpreted the results and repeated the cycle.

Adam is a still a prototype, but Professor Ross King, who led the research at Aberystwyth University, said that his team believes that its next robot, Eve, holds great promise for scientists searching for new drugs to combat diseases such as malaria and schistosomiasis, an infection caused by a type of parasitic worm in the tropics.

Duc Pham, professor of computer-controlled manufacture in the Manufacturing Engineering Center at Cardiff University, has welcomed the advance made at Cambridge and Aberystwyth. Pham said:

This is a clever application of robotics and computer software. Robots don’t tire, they can carry out repetitive work accurately, and computers can search through many possibilities very quickly to mine useful information from massive amounts of data. There are already many such applications in industry and business — for instance, robots are used in the automotive industry to assemble cars, and computers sift through huge amounts of data about our shopping habits to determine how groceries should be arranged in supermarkets.

But a robot doing original science? That really catches the imagination. I would not call this a robot scientist, however; it’s more like a junior lab assistant. It will be a long time before computers can replace human scientists.
