“Uruguay did what most nations still call impossible: it built a power grid that runs almost entirely on renewables—at half the cost of fossil fuels. The physicist who led that transformation says the same playbook could work anywhere—if governments have the courage to change the rules.”
Uruguay’s Renewable Charge: A Small Nation, A Big Lesson For The World
Uruguay built a power grid that runs 99% on renewables—at half the cost of fossil fuels. Here’s how its bold energy overhaul became a global model.

I wanted dinner recommendations so I scraped 13,000+ London restaurants and accidentally discovered Google Maps is running a shadow economy. Anyway here's a dashboard and a political economy thesis: open.substack.com/pub/laurenle...
How Google Maps quietly allocates survival across London’s restaurants - and how I built a dashboard to see through it
I wanted a dinner recommendation and got a research agenda instead. Using 13000+ restaurants, I rebuild its ratings with machine learning and map how algorithmic visibility actually distributes power.

Apologies to our hylobatid cousins who are surely better at critical thinking, but "look like a confused gibbon" is a great mental image
It's shockint how much I am seeing more and more people who very clearly don't know the basics. Like I expect it from the finance bros like musk or theil, but ive met PMs who absolutely believe the LLM is a god like entity, but look like confused Gibbons the minute I explain how they really work.

Very happy to share our recent work @cultivarium.bsky.social on genetic tools for Ideonella sakaiensis, a (Betaproteo-)bacterium that degrades PET plastic.
We identified a plasmid vector for the strain and generated a large RB-TnSeq library, screening for genes impacting plastic degradation.
