Interesting and important new paper: Microbial composition of purified waters 


By: Jonathan Eisen

There is an interesting and potentially important new paper out from Caitlin Proctor, Marc Edwards and Amy Pruden: Microbial composition of purified waters and implications for regrowth control in municipal water systems in Environmental Science: Water Research & Technology.  The abstract is below: The limits of water treatment to control microbial regrowth were examined using highly purified waters. Measurable microbial genetic material was detected in the product water…

Is your spacecraft contaminating the universe?


By: Jonathan Eisen

An article at Space.Com discusses a new push to make sure that spacecraft do not inadvertently contaminate the places they are visiting (e.g., Mars).  What microbes are on space vehicles and how to make sure the parts that are sent to other planets are "clean" or "sterile" is an interesting and active area of research.  We have written about this issue here on microBEnet in…

Simple & elegant solution to a big problem in DNA based microbial diversity studies


By: Jonathan Eisen

A new preprint has come out in PeerJ that presents a simple yet elegant solution to one of the bigger problems in DNA based microbial diversity studies.  The authors (Wenke Smets, Jonathan W Leff, Mark A Bradford, Rebecca L McCulley, Sarah Lebeer, Noah Fierer) show how one can use the addition of an internal standard prior to DNA extractions to allow for the estimation of…
