fun facts 🙌
Photographing ancient Baobab trees before they die. “The baobab trees of the African continent can live over 1,500 years—one was been documented living to 2,500 years old. The trees bear fruit and provide useful bark material (which regenerates) for communities. They are famous for appearing “upside down,” with widespread branches and roots. The trunks are exceptionally wide, reaching diameters of up to 46 feet.” | learn more
The myth that most Americans hate their jobs. I’m always eager to read contrarian arguments to pop culture themes. Here’s one that made me change my assumptions about recent workforce churn. “Resignations are rising because people are seeing more job listings, not because they’re feeling more Marxist.” | learn more
tech, startups, internet ⚡
When is it the right move for a startup to sue? When competing in a highly regulated market.

Now this: “Three quarters of the subjects were found to have plastic particles in the blood, serving as the first evidence that the material can end up in the human bloodstream.” | learn more
A locked-in man communicates in sentences by thought alone. “In a world first, the man was able to ask for soup, beer, and even talk about his son for the first time since becoming completely paralyzed.” | learn more
AI algorithm accurately predicts risk of heart attack within 5 years. Researchers are building toward a world where, “AI tools can swiftly analyze diagnostic imaging to deliver immediate risk reports to patients.” | learn more
teaching the kids 👩‍🏫
Why successful children don’t innovate. The author makes an evolutionary case to explain why human children are particularly bad at innovating. Quote from a recent paper he cites: “A decade ago, now-seminal work showed that children are strikingly unskilled at simple tool innovation. Since then, a surge of research has replicated these findings across diverse cultures, which has stimulated evocative yet unanswered questions.” | learn more
on the blockchain ⛓
Another big crypto hack: Axie Infinity’s Ronin network. Friendly reminder that the existence of blockchains with value creates a permanent incentive for people to steal that value. “This hack totals almost $625 million at current value, making it the largest decentralized finance hack to date…” | learn more
