A bit off topic but then again, perhaps not. We all know that a great deal of bioinformatics gets done in ad hoc ways in Excel.
The short version is that an error in an Excel formula may be driving trends in the global economy.
The formula is for the average growth in GDP for countries with high debt. The wrong formula changes the value from +2.2 to -0.1 and is cited as the justification for the global push to economic austerity. A bit melodramatic perhaps.
A simple error in a spreadsheet couldn't really drive world events now could it.
