OK so I know nothing about this journal Medical Science | Journal. But the cover of their May issue is a figure from a a paper on hospital microbial ecology. The article is Deepa S, Abishek MU, Venkatesha D. The air as harbinger of infections in critical care units. Medical Science, 2014, 8(28), 8-13). Here is one strange thing though – the cover image is from another paper: Figure 5 from The ignored diversity: complex bacterial communities in intensive care units revealed by 16S pyrosequencing.
It is a cool figure and it is from a paper I had missed on ICU microbial ecology so I am glad they used it.
Anyway – the papers are open access and both seem worth checking out.
