Preparing for the crewed Mars journey: Microbiota dynamics in the confined Mars500 habitat during simulated Mars flight and landing

Human exploration of planet Mars has a long history with number of robotic missions surveying the Martian surface and environment, including  the Viking program (1975), the Mars Exploration Rover Mission (2003), the Phoenix lander (2008), and the Mars Science Laboratory (2012). For the future human space exploration, crewed Mars mission is considered as one of …

Over 1,200 Built Environment Genomes from Metagenomes

We were super excited to see the recent paper “Recovery of nearly 8,000 metagenome-assembled genomes substantially expands the tree of life“.  Really, the title says it all… the authors took hundreds of published metagenomic studies (focusing on non-human environments) and assembled thousands of genomes.  Awesome. But we were curious how many of these genomes came …

Today in possibly interesting science but needless fear mongering ..

So this sounds like there may be some interesting science going on here: Zero gravity had unexpected effects on E. coli samples, causing them to behave differently. That could present problems trying to treat them. Source: Space-Grown Bacteria Could Pose Major Problems for Astronauts But the article includes a bunch of needless fear mongering. What …

Of possible interest: Airborne bacterial assemblage in a zero carbon building: A case study

Of possible interest: Airborne bacterial assemblage in a zero carbon building: A case study – Leung – 2017 – Indoor Air – Wiley Online Library Abstract: Currently, there is little information pertaining to the airborne bacterial communities of green buildings. In this case study, the air bacterial community of a zero carbon building (ZCB) in …

Of possible interest: Bacterial diversity among four healthcare-associated institutes in Taiwan

Quick post – paper of possible interest:: Bacterial diversity among four healthcare-associated institutes in Taiwan | Scientific Reports Abstract Indoor microbial communities have important implications for human health, especially in health-care institutes (HCIs). The factors that determine the diversity and composition of microbiomes in a built environment remain unclear. Herein, we used 16S rRNA amplicon …

Of possible interest: Seasonal variation characteristic of inhalable microbial communities in PM2.5 in Beijing 

Quick post – paper of possible interest:: Seasonal variation characteristic of inhalable microbial communities in PM2.5 in Beijing city, China – ScienceDirect   Abstract: Bacteria and fungi are primary constituents of airborne microbes in fine particulate matter (PM2.5) and significantly impact human health. However, hitherto, seasonal variation and effect of air pollution on microbial community …

Master’s Thesis of Possible Interest: role of hospital toilets in microbial dissemination & the effectiveness of UV C 

Just got notified of this via some automated Google Scholar searchers and it seems like it might be of interest: Source: The role of hospital toilets in microbial dissemination and the effectiveness of ultraviolet C irradiation – UBC Library Open Collections Master’s thesis by Jesse Cooper from UBC.   See some discussion of this on …

Worth a look: new paper on “The application of project-based learning in bioinformatics training”

  This new paper in PLOS Computational. Biology may be of interest: : The application of project-based learning in bioinformatics training by Emery LR and Morgan SL. Although many out there may already be doing projects based learning for bioinformatics, many others are not.  This paper discusses how the authors added a projects component to an existing course …

NAS Study released: #MOBEstudy “Microbiomes of the Built Environment: A Research Agenda for Indoor Microbiology, Human Health, and Buildings”

So this is the culmination of a huge amount of work by a large number of folks.   The National Academy of Sciences (NAS) just released a new report “Microbiomes of the Built Environment: A Research Agenda for Indoor Microbiology, Human Health, and Buildings”.  This report was requested by the Alfred P. Sloan Foundation, the National …

“Schrödinger’s microbes: Tools for distinguishing the living from the dead in microbial ecosystems”

A few years ago I was hearing increasing discussion about the idea that much of the microbiology of the built environment was “stamp collecting” and that the indoor microbiome might consist largely of dead or non-viable material passively deposited indoors.  Many pweople argued that there was a need for better tools (or increased use of …
