Press, press, press!

Over the last week, I have been featured in media in different ways, so here’s a quick summary.

I was asked to provide a comment on a recent paper on how microplastics affect antibiotic resistance development (1) for an article in Scientific American (2). I am not sure I had that much intelligent to say, other than to caution about jumping to conclusions, as we still know quite little about the risks associated with microplastics and AMR: “How much of a threat plastic-derived drug-resistant pathogens pose to humans is a question that remains to be fully understood” is one of my two quotes from the article.

I also was interviewed last week for Swedish Radio’s Vetenskapsradion (in Swedish) about another study showing that, e.g., ibuprofen could drive bacteria to higher mutation rates, indirectly triggering antibiotic resistance development (3). Such interaction effects have also been seen elsewhere (4), but the fact that they see this effect for such a commonly used drug as ibuprofen – one of our most standard painkillers – is a little bit concerning. Still I stress in the interview that we need to know much more about these interaction effects before jumping to clinical guidance.

Finally, the Foundation for Strategic Research has released the video they recorded about our research last fall. It is in Swedish, but with English subtitles, so this could be worth a watch!
