So researchers asked gamers to try to solve this partially protein. Within three weeks, the gamers fund a good solution. The scientists then return it and were able to completely determine the protein’s structure. Having the structure could inform the use of drugs to block the enzyme, and provide another tool against retroviruses, including HIV. The researchers say that people have much better special reasoning skills than computers -- and that having both humans and machines attract the problem might overcome virus structural challenges. The results appear in the journal Nature Structural and Molecular Biology. Co-authored by researchers -- and a number of gamers.
