How will humans, by nature social animals, fare when isolated? — The Economist

I have worried about the social and mental health effects of the lockdown measures being implemented. But even I hadn’t anticipated quite how much conditions like post-traumatic stress disorder appear to be common following quarantines.

According to a rapid review of the psychological effects of quarantines, published on March 14th in the Lancet, a British medical journal, some studies suggest that the impact of quarantines can be so severe as to result in a diagnosis of post-traumatic stress disorder…

One study from 2009 looked at hospital employees in Beijing who in 2003 were exposed to severe acute respiratory syndrome (SARS), which, like covid-19, is caused by a coronavirus. The authors found that, three years later, having been quarantined was a predictor of post-traumatic-stress symptoms. Another study… found that the mean post-traumatic-stress scores were four times higher in children who had been isolated.

Elsewhere, the article highlights as a problem the fact that 67% of 18–34-year-olds are finding it hard to remain upbeat. But I’m more concerned about those who are managing to be upbeat among all this madness.

Why being kind could help you live longer — Lauren Turner — BBC News

Illustration of hands holding hearts

It has long been known that being kind to others makes you feel good and can improve your mental health. Now it seems there is a growing body of evidence suggesting that it can increase your life expectancy.

“Living with people who treat you, at best, with disregard or a lack of concern, and at worst with open hostility, is bad for you. It shortens your life, quite literally,” [Daniel Fessler] says.

“Conversely, both receiving kindness from others, and providing kindness, both of those things are the antithesis of this toxic stress situation. And they’re good for you.”

Academia uneasy with lack of diversity on ‘dude walls’ of honour — Nell Greenfieldboyce — NPR

A 'dude wall' featuring several portraits of white old men

On the campaign to remove — or make less prominent — walls of portraits of old white men from academia’s past.

“It just sends the message, every day when you walk by it, that science consists of old white men,” says [neuroscientist Leslie] Vosshall. “I think every institution needs to go out into the hallway and ask, ‘What kind of message are we sending with these oil portraits and dusty old photographs?'”

While defenders of dude walls warn of erasing history, the counterpoint is powerful:

…some argue that the old portraits themselves have erased history, by glorifying white men who hold power while ignoring the contributions to science and medicine made by women and people of colour.

Celebrations of individuals in this way always make me wary. It seems to be particularly common in higher education, where awards and buildings are routinely named after white males.

But very few breakthroughs are truly the work of a single individual. The people honoured in this way are likely the people most adept at taking all the credit for other people’s work.

Testing the sound mirrors that protected Britain

I very rarely link to (or even watch) a video. But I am happy to make an exception for Tom Scott’s excellent entertaining and educational videos.

Here, he tests concrete sound mirrors with drones. I’m fascinated by sound mirrors — an early 20th century technology designed to provide early warning of approaching aircraft, which became obsolete quickly as aircraft speeds increased, and radar took over.

Was there a civilisation on Earth before humans?

This is mind-blowing.

Perhaps, for example, some early mammal rose briefly to civilization building during the Paleocene epoch about 60 million years ago. There are fossils, of course. But the fraction of life that gets fossilized is always minuscule and varies a lot depending on time and habitat. It would be easy, therefore, to miss an industrial civilization that only lasted 100,000 years—which would be 500 times longer than our industrial civilization has made it so far.

What colour is a tennis ball?

It’s the dress part two!

I make this decision as much on the basis of what I think I know about tennis balls—that they are yellow—as I do on what color I recall that they looked when I last saw one… In other words, like the color of a lot of objects, how we label [a tennis ball] is determined both by perceptual and cognitive factors: the actual physical light entering your eye and … knowledge about what people have typically labeled the objects.

I have to say, it never occurred to me that a tennis ball might be any colour other than yellow.

How many dimensions are there, and what do they do to reality?

Reading this article is the closest I have ever come to understanding what is meant by having more than four dimensions.

> Imagine… you are an ant living on a long, very thin length of hose. You could run along the hose backward and forward without ever being aware of the tiny circle-dimension under your feet. Only your ant-physicists with their powerful ant-microscopes can see this tiny dimension.

Ed Yong: I spent two years trying to fix the gender imbalance in my stories

…I looked back at the pieces that I had published in 2016 thus far. Across all 23 of them, 24 percent of the quoted sources were women. And of those stories, 35 percent featured no female voices at all. That surprised me. I knew it wasn’t going to be 50 percent, but I didn’t think it would be that low, either. I knew that I care about equality, so I deluded myself into thinking that I wasn’t part of the problem. I assumed that my passive concern would be enough. Passive concern never is.
