A Regular Ray of Sunshine

At The Scientist, PNNL's Steven Wiley discusses why biological data isn't readily available online -- despite all the calls for it to be shared. He says there are "enormous hurdles that currently make it impractical" and that for some data, such as western blots and ELISA, converting it all to a standard format may not be worth the effort, though sharing other data like DNA sequence or protein structure may be useful. However, Wiley says the main stumbling block to sharing data is "biologists' lack of motivation to do it" and, given the example of the Alliance for Cell Signaling, even if the data is available it may not be widely used.
