I have not read on the subject before. I generally write about articles that I read as I peruse the literature. If I come across an article discussing thermogenesis I will for certain talk about it.

I typically try to break down a new piece of work, rather than discuss a topic in detail, though I'm not against the idea of a summary article where I break down a topic using the work of a few articles. The challenge in that case is finding open access materials that allow me to reproduce their figures so I can try to explain them in simpler terms. It's not so bad with one article, but more than one and it's trickier. This is why I try to have a bit of a background section to start the post.
