The Weight of a Cell
Ella Watkins-Dulaney Microbes are so small that tens of thousands could fit in the space of the period at the end of this sentence.

It’s the Housing, Stupid
A few weeks ago, I was on The Compound and Friends, and there was a debate about why we were seeing 2021-like meme stock activity and money market funds holding record assets at the same time. For context, both of these things are true. If we look at the performance of the 100 most shorted […]
The new geography of stolen goods
Aug 17th 2025 | Felixstowe The MSC Ruby is almost ready to leave Felixstowe. Seven remote-controlled gantry cranes are still at work, stacking containers in the ship’s bays. Some 11,000 containers pass through this port each day, making it Britain’s primary conduit to the arteries of global trade. The Ruby’s next call is Gran Canaria—then, […]
