BBC Crowd Science is one of my favourite podcasts. Essentially, it's a podcast where people from all over the world send them questions on matters of science, and they answer them.
Back at the end of 2017, Crowd Science has featured an episode based on a question from yours truly. I asked them to tell me about the dust in my home and whether I should worry about it (or even clean it). To help them answer my questions, I had posted them dust samples from various sources in my home. Luckily, there is no supply shortage there.
You can read and listen to this episode here.
This week, Crowd Science followed up on my question with yet another episode that goes even deeper into the matter and looks at whether household microbes help or harm us.
You can listen to this newer episode (and to yours truly, again), here.
While at it, do consider subscribing to BBC Crowd Science on whatever platform it is that you're listening to podcasts through. It's a great podcast even on episodes that do not feature me.
