It is a tool that have using for managing my scientific reference papers. It is one of the best tools for that I have used so far. I have been using it for the last two months, still learning its features but I am really excited about the tool. I don’t have to print the paper and highlight the important points, file it away in the cabins and then start searching for it later. Oh what a relief !!. Thanks to the great folks of George Mason University‚Äôs Center for History and New Media for having produced such a software.

But the sad thing is that I need to maintain the same set of files on both my laptop and desktop as the reference material is stored in the hard disk. I cannot directly one from the other :(. But there are several new features being added to zotero to make it more powerful, so I am sure this will be taken into account.

All in all I feel Zotero is an essential tool for anyone doing research online.

Error bars are almost shown in most of graphs used in research papers. In my experience not many of us give much importance to the error bars, questions about it only come from the group leader or the bosses. In several papers, the figure legends never describe kind of error bars used. Even in my statistics classes in biology the importance of error bars and their interpretation was never explained. Came across this nice paper in Journal of Cell Biology explaining usage of error bars in experimental biology.

They explain the different types of error bars used for descriptive and inferential statistics. The formulas are well explained and illustrated with good biological examples.
