September 3 (electronically) Nature devoted a segment of an issue to "big data". The hard copy journal was published Sept. 4, v. 455, issue no. 7209.
It includes a commentary, "How do Your Data Grow?" by Clifford Lynch of the Coalition for Networked Information. Two news features: operations at a "petacentre" - facility which handles petabytes of data - by blogger Cory Doctorow, and one about using wikis to make sense of the mountains of data generated by genomics and other fields.
Another article explores visualization, not just for presenting data, but using it to design the original experiments ("Distilling Meaning from Data" by Felice Frankel and Rosalind Reid). In "The Next Google" a number of visionaries predict what the next big thing might be, from robots to RFI tags, to the Semantic Web and video visors. The longer piece is about data curation for biological information.
Some food for thought here.
Note: Some content is available only on the electronic journal. The link goes to a page called "NatureNews". I noticed that there are more articles on the internet and in the hard copy journal that aren't linked to this "NatureNews" page.
