A new artificial intelligence tool captures strategies used by top players of an Internet-based video game to design new RNA molecules. Rohan Koodli and colleagues from the massive open Eterna lab present the tool EternaBrain in PLOS Computational Biology . Eterna is headed by the laboratory of Prof. Rhiju Das at the Stanford University School of Medicine in California.
RNA molecules occur naturally in all living cells and fulfill important biological functions. In recent years, there has been a strong interest in the development of new RNA structures for cancer treatment, CRISPR gene editing and much more. However, each RNA structure consists of a long sequence of four building blocks, and the determination of the exact sequence required to construct a particular structure can be computationally difficult.
In the new study, Koodli, Das, and colleagues examined the Eterna Internet-based video game, a civic science initiative to tackle the computational challenges of RNA design. Eterna presents each player with a target RNA structure and the player tries to find an RNA sequence that allows the finished molecule to fold into the desired shape. Some players outperform the best computer-automated methods to solve these challenges.

"Our results suggest that it should be possible to create automated algorithms for computer RNA design that emulate or outperform human RNA designers," says Das. "But we are not there yet, we still have much to learn from players and AI researchers."
Next, researchers will see if they can outperform top players by integrating EternaBrain with other computer-aided approaches to RNA design. "We also hope to be able to apply EternaBrain to more complicated issues that Eterna players solve, including the design of RNA computers and 3-D machines, as well as learning design rules from actual wet laboratory data," says Das.
