I've played this twice now. I love the theme of trying to research, experiment, and then publish the results of new scientific discoveries. The worker placement mechanic (simulating the amount of effort you, as a scientist, devote to different aspects of the scientific process) works well and so too does the melding of this mechanic onto the tech tree of scientific discoveries. The artwork is superb. The only problem with the game? It takes too long to play. And I think the design of the board is partly to blame- it simply takes too much focus and concentration to figure out what is connected to what on the tech tree, who has published (versus researched or experimented on) what, and so forth. While beautiful, I suspect a change in the design of the gameboard itself could cut 30 minutes or more of player 'analysis' time from the game.
