Staying alive in the built environment

Skin-associated bacteria are abundant indoors. A comparison across studies shows that up to 30% of bacterial sequences detected indoors are associated with the human body (see Table 1 in this 2016 paper). I’ve been kind of skeptical that these sequences represented live organisms, however. Rather, I suspected the high proportion of sequences that were human-associated …

Space Station conditions are selective but do not alter microbial characteristics relevant to human health

Human space exploration beyond Earth and Moon is a declared goal of NASA, ESA, Roscosmos and other space-faring agencies, with human Mars mission envisioned in the near future. One of the major challenges of the mission is protecting the human crew from illness and infection caused by harmful biological contaminants. To evaluate these challenges in …

The report from Kaunas: ISES-ISIAQ 2019

Last week, the International Societies of Exposure Science and Indoor Air Quality had their joint meeting in Kaunas, Lithuania. The meeting featured a lot of great research on topics ranging from the thermal comfort of clothes to exposure to heavy metals from e-cigarettes and everything in between. While we can’t summarize the whole meeting here, …

A different suite: distinct fungal communities in water-damaged homes

How microbial profiles differ between water-damaged and dry buildings is not well known. It’s only logical that where moisture is available indoors, microorganism will grow. Yet, measured microbial products do not show consistent differences between wet and dry homes. Because wet homes are associated with a variety of health risks, it’s important to identify the …

Man-made microbial resistances in built environments

Antibiotic resistance has been assessed to rise to dangerously high levels in all parts of the world, and new resistance mechanisms are emerging and spreading globally. At the same time the number of people dying from antibiotic-resistant bacteria is increasing. The World Health Organization considers the spread of antibiotic resistance and appropriate countermeasures as one …

Wrap up of Talk by Maria Gloria Dominguez Bello at UC Davis

Maria Gloria Dominguez-Bello gave a talk at UC Davis on March 11, 2019.  This talk was part of the Storer Lectureship in Life Sciences series. Her talk was on “The Human Microbiome in an Age of Disruptive Change” and it was really quite good. I live Tweeted the talk and if you are interested the …

Journal Club: “Microwave detection and quantification of water hidden in and on building materials…”

Just a quick journal club post here, got pointed to this really interesting sounding article by David Thaler recently “Microwave detection and quantification of water hidden in and on building materials: implications for healthy buildings and microbiome studies.” As I understand the problem, it can be hard to quantify water in buildings, particularly water hidden …

An Art + Science Pop-up Exhibit: Community of Microbes

The initial discovery of microorganisms by Robert Hooke and Antonie van Leeuwenhoek in the mid to late 1600’s was an exploration of wonder. The two were some of the first to visually journey into the microscopic realm with the aid of simple microscopes. They turned their gaze to the ordinary spaces around us. Pouring into …
