*PLOS Computational Biology T-shirt competition* For the fourth year in a row, PLOS Computational Biology is calling on scientists and designers to send eye-catching designs that appeal to the computational biology community and encapsulate a recent advance or innovation in the field. The creator(s) of the winning design will receive a free t-shirt and a write-up of their design and research on PLOS Biologue. This year’s PLOS Computational Biology t-shirt will debut at *July’s ISMB/ECCB 2013 meeting in Berlin*. To enter the competition, send your design to ploscompbiol[at]plos.org by *Tuesday May 14th 2013*.
