In the nineteenth century, the societies of Europe and North America were profoundly transformed by the vast railway networks they built. When these railway networks entered cities, however, they faced a crucial problem: they had to stop.

When FDA standards for drug safety and efficacy became stricter in the 1960s, drug developers almost abandoned rare diseases due to regulator unfamiliarity and low revenue potential.

There exists a popular sentiment that we can’t build as well as we used to and our best days are behind us. But when we choose to, we can still build beautiful and interesting developments. Here’s a tour of 10 new projects that are creating a better built environment. 🧵

Planes aren’t getting faster. Buildings in the developed world aren’t getting taller. Roads are getting slower. But the world’s largest passenger ship record has been broken 9 times this century. They show what is possible w/o the constraints that stifle progress on dry land. 🧵

Madrid’s metro was 71 miles long in 1995. That would be the world’s 51st longest today, reasonable considering Madrid is the 57th largest city by population. Yet over 12 years, the metro would ~3x in length at costs much lower than was thought possible. Here’s how they did it. 🧵

Very informative article about how animals were and are used as chemical factories. Lots of stuff in there I had never heard of! I’m in awe of the people who discovered all of this, but even more so of modern biotechnology offering synthetic alternatives. worksinprogress.co/issue/animal...

sick public transit, gloria @seung.bsky.social · 06/12/2024

really great read on how Madrid (and Spain by large) have some of the cost-effective transit constructions in the world worksinprogress.co/issue/how-ma...

Madrid’s success provides four key lessons for policymakers and engineers in places that struggle to cheaply build new transit.

City-level powers rewarded fast, inexpensive delivery. The structure of the Community of Madrid concentrated the planning, funding, and construction powers at the right level to deliver the project. This enabled political entrepreneurs to make electoral promises about delivering new infrastructure and have their political fortunes dependent on success.
Time is money. The regional government streamlined environmental and planning processes and the company that oversaw construction expedited the building by tunneling 24/7.
Trade-offs matter and need to be explicitly considered. The metro planners recognized the trade-offs that exist between station design and cost, signaling complexity and how much testing is required, and tried-and-tested technology versus innovation.
A pipeline of projects enables investment in state capacity. Madrid built the necessary state capacity to deliver the project, with experienced engineers and managers working in-house to deliver the technical design and oversee construction. The public company tasked with construction could pay extra to hire experts and procured based on cost and quality instead of just the lowest-cost bid.

“Every year, over 700,000 horseshoe crabs are caught and bled. The global vaccine industry uses an estimated 600 million chicken eggs a year to produce influenza vaccines. And we boil between 420 billion and 1 trillion silkworms every year to produce silk.” Could we replace them with synthetic bio?

A new piece by Salim Furth makes important points on the relationships between homelessness and housing supply, which is more complicated than some analyses suggest: worksinprogress.co/issue/why-ho...

Why do high-cost cities have more homelessness? It's not just about rents — it’s also about the rooms friends and family can’t afford to share.

Bsky folks and #EconSky, The cool people at @worksinprogress.bsky.social invited me to write an article for their December issue about the fascinating story of innovation in US dairy genetics. Roughly based on some of my research in this area. My highlights: worksinprogress.co/issue/how-bi...
