AAAS vs. Google. Fight! http://science.sciencemag.org/
But seriously to my academic mind: Journal = published, Notebook = notes from experiments.
Besides the name issue, it looks Science Journal is part of a wide host of open source tools aimed at enabling data collection and experimental control. The big player in this area is National Instruments/Labview.
I wonder if there's room in the market for a mid-level player (or if one already exists). Utilize the open source developments and create a "certified and supported" toolset for experimental control. Cheaper than NI, but more reliable than "this firmware I found on github".
