Why we need more death rays

Plus: It's my lucky week! (#544)

This is David, your friendly guide to the world wild web, and you're reading the Weekly Filet, the newsletter for curious minds who love when something makes them go «Huh, I never thought of it this way!». As every Friday, I'm here to help you make sense of what’s happening, and imagine what could be. It's great to have you.

1. The death rays that guard life

Longtime readers know of my favourite nerdy subgenre: the in-depth profile of stuff our modern world runs on. Sometimes, that stuff is invisible. Like the air we breathe, and ultraviolet light that we can use to disinfect it. This profile ends with a thought-provoking question: We transformed public health by doing everything we can to guarantee clean water. We have the means to do the same with air. So how come – even after the coronavirus pandemic – clean air isn't as universal and expected as clean water?

We disinfect water before we drink it. Why don’t we disinfect the air before we breathe it?

2. How to live a life that actually matters

The essence of Rutger Bregman's new book, and the movement he has started – The School of Moral Ambition – in one extremely well-produced 20-minute video.

3. The rise and rise of Zohran Mamdani

A 33-year-old Muslim born in Uganda will most likely become the next mayor of New York City. With everything that's going terribly wrong in the US right now, it's important to not forget that other things are happening as well. Good profile from the New Statesman.

4. The Obituary

A gripping, maddening podcast episode. The story of how anti-vax conspiracy theorists terrorise a man who just lost his pregnant wife – all because of two innocuous words in her obituary.

Not long after Alex’s wife Whitney dies, he looks at her obituary and discovers something strange. A sect of people online has hijacked her story and turned it into…

5. Why randomized controlled trials matter and the procedures that strengthen them

It's my lucky week, with another exhibit from my favourite nerdy subgenre, the in-depth profile of stuff our modern world runs on. Another invisible one, a scientific method. Randomised controlled trials help us establish cause and effect. They let us figure out whether a drug or a treatment works – and how well. Discovering what works can save lives. But just as important is determining what doesn't work – the piece highlights how we've gotten better at the latter.

Randomized controlled trials are a key tool to study cause and effect. Why do they matter and how do they work?

Books for curious minds

Some new ones as I read them, some older ones that continue to inform how I look at the world and myself.

The FT business book of the year is always a safe pick. This from 2021 is no exception. A tour de force, and an alarming view into things to come. Buy it here.

A gem from the archive

What Makes a Good Listener?
I like this way of putting it: A good listener is like an editor. One that — «in the kindest way possible» — helps the other person express what they really intend to say. Read more
