1. A few weeks ago, several Italian doctors made quite a stir in the news. They claimed that the SARS-CoV-2 coronavirus was "losing potency", and hinted at genetic changes in the virus.

1. Many people have asked me whether the ongoing Black Lives Matter protests around the country pose a risk of increasing coronavirus spread.

As a scientist, I acknowledge that they may.

As a citizen, I wholeheartedly support the protests nonetheless.

1. A thread on selection bias, COVID testing, and a failure to detect community spread in the US that cost us a month or more in the pandemic response.

In my forthcoming book with @JevinWest, we devote an entire chapter to a class of statistical pitfalls known as selection bias.

1. A short thread about best and worst case models of coronavirus.

I've talked about how the @UW_IHME model strikes me as a best case model (at least given current data inputs) and its confidence ranges represent uncertainty around that best case, not best-to-worst cases.

1. This is going to be a personal thread about the experience of working at the intersection of infectious disease modeling and the study of misinformation during the worst pandemic in a century.

If you're just interested in what is happening with the virus, you can skip it.

1. A very short thread on the power of data graphics and scientific communication.

Roughly a week ago, some very smart person* sat down, drew this graph, and saved lives.

(*It's 2 AM. Without an economist subscription, I can't quickly discover whom. Maybe someone can help.)

Today I met a fledgling crow who could almost but not quite fly, who use entirely unafraid of me, and whose parents had no concern about my presence. As a result, I was able to take a number of closeup pictures.

With this little bird's help, let's talk a bit about crow anatomy.
