From researchers at Bauhaus-University Weimar, this video shows how various methods of covering a cough change the spread of air from your mouth.

Here are some useful distractions for you as you stay-at-home and wait for an unknown amount of time. Read More
Based on cellphone data from Cuebiq, The New York Times looked at how different parts of the country reduced their travel between the end of February and the end of March. Some counties really stayed at home. Some not so much:
In areas where public officials have resisted or delayed stay-at-home orders, people changed their habits far less. Though travel distances in those places have fallen drastically, last week they were still typically more than three times those in areas that had imposed lockdown orders, the analysis shows.
The streets are quiet here in northern California, so this is pretty shocking for me. If you can, stay at home, folks. It’s inconvenient, but it’s a small sacrifice for something much bigger.
As you would expect, not many people are flying these days. The Washington Post mapped the halts around the world:
On Tuesday, the TSA screened just over 146,000 passengers at U.S. airports, a 94 percent plunge from 2.4 million on the same day last year. By the end of March, the TSA screened just over 35 million passengers at U.S. airports during the month, a 50 percent decrease from more than 70 million at the end of March last year.
At this point, I would gladly wait a couple of hours in a security line for just a taste of normalcy.
Fatalities from Covid-19 range from the hundreds of thousands to the millions. Nobody knows for sure. These predictions are based on statistical models, which are based on data, which aren’t consistent and reliable yet. FiveThirtyEight, whose bread and butter is models and forecasts, breaks down the challenges of making a model and why they haven’t provided any.
On the surface, the decennial census seems straightforward. Count everyone in the country and you’re done. But the way we’ve done that has changed over the decades. The Pudding and Alec Barrett of TWO-N looked at the changes through the lens of questions asked:
We looked at every question on every census from 1790 to 2020. The questions—over 600 in total—tell us a lot about the country’s priorities, norms, and biases in each decade. They depict an evolving country: a modernizing economy, a diversifying population, an imperfect but expanding set of civil and human rights, and a growing list of armed conflicts in its memory. What themes and trends will you notice?

Comprehensive national data on Covid-19 has been hard to come by through government agencies. The New York Times released their own dataset and will be updating regularly:
The tracking effort grew from a handful of Times correspondents to a large team of journalists that includes experts in data and graphics, staff news assistants and freelance reporters, as well as journalism students from Northwestern University, the University of Missouri and the University of Nebraska-Lincoln. The reporting continues nearly all day and night, seven days a week, across U.S. time zones, to record as many details as possible about every case in real time. The Times is committed to collecting as much data as possible in connection with the outbreak and is collaborating with the University of California, Berkeley, on an effort in that state.
