After finishing my first episode of TWiV, I realized that I needed a refresher course on viruses. I want to know the basics, without taking biology again.

YouTube is both a cesspool, a library, and my first stop when researching a subject. I have learned to look for older videos YouTube Creators have not repurposed into sponsor driven streams filled with fluff, filler, and sponsors. This video is direct, easy to understand and has helpful animations.

After listening to a month of TWiV episodes, however, I do have one nit to pick, and I think my Hillsboro High School science teacher would agree. Viruses do not self-replicate—they need cells to do that—and they do not infect, they simply exist. In the video the viruses are moving around infecting cells. Viruses do not move. A cell must come to a virus to be infected. That’s why washing your hands, not touching your face, and physical distancing are so important.

This Week in Virology. The podcast about viruses. The kind that make you sick. A refrain I hear more than once a week since I started listening to this excellent podcast all about the coronavirus. No. That's not right. This podcast is all about viruses; the kind that make you sick.

In late March, I realized my regular sources were not enough to keep me informed about the growing pandemic. At that time, the World Health Organization had not declared a pandemic, but I was calling coronavirus endemic (community transmissions—transmissions that could not be traced to a source of the virus—were common). The legal definitions did not matter to me, I knew we were stuck with coronavirus and the resulting infection: COVID-19, until we get a vaccine. I needed a better source of information.

Twenty Years of Climate Change

Do you know what scares me? The comments attached to this video on YouTube. There was a time I would dismiss such things as trolls, attention seekers, and link builders, but then Trump happened. The comments run the full gamut, from not understanding the impact of climate change on famine and poverty to denying the moon landing, to flat Earthers.

China is Killing Itself

In October, the Earth Observatory project posted a photo of the smog over China.  The haze was thick enough to completely hide the land or water surface below, and it extended far to the south and east. The air is so bad in Beijing that the US Embassy measures and shares the air quality on a Twitter feed.

I wanted to share this image to give you an idea of how bad the situation is. The problem with pollution in China is not just Beijing. It stretches for hundreds of miles. China’s pollution problem is so bad it is changing our climate. When you hear about a product recall, such as pet food contaminated with steroids, or tea poisoned by diesel truck fumes that is a side effect of China’s poor environmental regulations as well.
