With Covid-19, one of the big challenges we face is the rapid mutations in the viral genetic code that have produced several beneficial—from the virus’ standpoint—adaptations. Several days ago the New York Times published a nice, illustrated piece that showed just what these mutations look like.
Of course, these were not just nice illustrations of protein molecules, but the screenshot below is of the code itself and you can see how just a few alterations can produce subtle, but impactful, effects.
In a biological sense, these mutations are nothing new. In fact, humanity wouldn’t be humanity but for mutations. Rather we are seeing evolution play out in front of our eyes—albeit eyes locked in the same household for nearly a year now—as the virus evolves adaptations better suited to spreading and surviving in a host population.
The piece includes several illustrations, but begins with an overall, simplified diagram of the virus and where its genetic code lies. And then breaks that code down similar to a stacked bar chart.
Designers identify where in the code the different mutations occur and the type of mutation. Later on in the piece we see a map of where this particular variant can be found.
I might come back to that map later, so I won’t comment too much on it here.
But I think this piece does a great job of showcasing just what we mean when we talk about virus mutations. It’s really just a beneficial slip up in the genetic alphabet.

I do not know a thing about horses. I leave that knowledge to others in my family. However, this piece from the South China Morning Post explains quite a bit of why the thoroughbred is such a famous type of horse for racing.
The Washington Post looks at sleep and how lack thereof may lead to various health problems, including Alzheimers, diabetes, and others. Maybe this means I have a reason to sleep in the mornings now…probably not.

From XKCD comes an informative infographic about your central visual field. As always, it’s quite informative. It’s not quite light hearted for Friday, but you’ll probably get an odd look or a laugh when you move your face really close to your monitor…
Also as always, credit for the piece goes to Randall Munroe.
From the Sydney Morning Herald, we have a link to an interactive infographic published by the Cancer Council of Australia, a non-profit that seeks to reduce the impact of cancer upon Australia. It is not the most graphical by way of charts, but offers the user “playful” interactions with statistics to better inform him or her about the causes and impacts of cancer. The format is also interesting in that it mimics the fad in infographics of the long, vertical scroll page. But here it is done to much better and ostensibly more useful effect. Useful in the sense of trying to help people.
People are nothing more than dirty stinking apes. Especially when it comes to microbes. On Monday the New York Times published an infographic that visualised the data on the prevalence and abundance of different microbes across a sample of over 200 individuals. That is to say the visualisation looks at where microbes are most common and just how common they are in that location.
