Elsevier has a 38% profit margin, and the other journal publishers aren't far behind.
"academic publishing is dominated by profit-oriented, multinational companies for whom scientific knowledge is a commodity to be sold back to the academic community who created it... The dominant four collectively generated... $12 billion in profits between 2019 and 2024."

Good morning with good news: India meets 50% renewables & nuclear capacity target 5 years early!
As clean capacity deploys, clean electricity production surges.
Solar grew from 5 TWh in 2014 to 48 TWh in 2019 & 137 TWh in 2024.
Hydro was 157 TWh; wind 82 TWh; nuclear 55 TWh in 2024. #energysky

In the last decades, the world has made fantastic progress against extreme poverty. In 1990, 2.3 billion people lived in extreme poverty. Since then, the number of extremely poor people has declined by 1.5 *billion* people. 🧵

GDP: We Really Don’t Know How Good We Have It—Asterisk
Everyone loves the hockey stick graph of long-run economic growth. For some, it's the basis of an entire worldview. Unfortunately, the numbers don’t add up.

A 4-year limit on student visa length would upend PhD programs.
I know there's a lot happening today, but this is sneaking in under the radar. This proposed new rule would absolutely crush foreign PhD students, potentially making it impossible for them to enroll with any certainty of their ability to finish www.politico.com/news/2025/08...

We ran a randomized controlled trial to see how much AI coding tools speed up experienced open-source developers.
The results surprised us: Developers thought they were 20% faster with AI tools, but they were actually 19% slower when they had access to AI than when they didn't.

Since 2000, Gavi has helped get vaccines to 1.1 billion children. The U.S. announced that, after this year, it’s pulling out all its money. If that happens, Gavi estimates that 75 million children will miss vaccinations over the next five years—and of those, 1.2 million children will die.

Household resources for the bottom income decile would fall by 4% ($1,600), largely due to Medicaid & SNAP cuts.
The top income decile will see increases of 2.3% ($12,000), largely due to tax cuts.
