Fishdraw. “Procedurally generated fish drawings.” | learn more or see it in action
Dubai is using laser drones to shock rainwater out of the sky. “Rather than dispersing particulates as done in traditional cloud seeding, the Emirati Weather Center is using drones to ‘zap’ the air into submission. These drones are designed to target certain clouds and use electrical discharges via concentrated lasers to forcibly pool water droplets in the air, thus triggering desired rainfall.” | learn more
oh, chicago 🏆
Chicago ugly buildings tour. “Chicago is known for its incredible architecture — but not every building is a stunner. A tour guide is showing off the city’s most reviled buildings in a new tour.” | learn more
tech, startups, internet ⚡
Nvidia digitized its CEO. “Nvidia scanned its CEO, Jensen Huang, and trained an AI to mimic his gestures, creating a virtual replica of Huang, which the company used as part of its April keynote. In a blog post, Nvidia revealed that Huang did not do the keynote presentation at the company’s GTC conference in April.” | learn more
The clipper chip. “How once upon a time the government wanted to put a backdoor in your phone.” | learn more
better doing 🎯
Trust your team. From Sean Harper, CEO and co-founder at Kin Insurance. “At my company, we have a bias toward action. We make it clear to employees at every level that the person closest to any problem should solve it. Moreover, we make sure they shouldn’t have to go through layers of management to do it. This idea is central to our company culture, and I argue it’s a major component of our success.” | learn more
to your health ⚕
When Buddhism goes bad. “As an instructor in Mindfulness-Based Stress Reduction (MBSR), I spent four years teaching meditation as a full-time job.” Then one day, Dan Lawton discovered firsthand the rarely-discussed evidence of meditation’s risk, “including involuntary convulsions, panic, anxiety, dissociation and perceptual hypersensitivity—a far cry from the mainstream branding of mindfulness meditation as a panacea for all our woes.” | learn more
Adumbrations Of Aducanumab. Don’t let the big words scare you off. This is an insightful analysis of the FDA’s recent approval of a new Alzheimers drug from Scott Alexander. Conclusion: unbundle the FDA! | learn more
under the microscope 🔬
People whose enzymes work slowly can’t handle the stress. “The hardworking ones are precisely four times faster than the lazy ones. The hardworking enzymes are built with valine, the lazy enzymes with methionine.” | learn more
A link between severity of COVID-19 infections and Neanderthal DNA. Covid-19 isn’t the theme of this story, but it is one interesting observation. “Genetic scientists from the University of California Santa Cruz have learned that just 7%—or less—of our DNA is unique to the human species, with the remainder of our genomes coming from other archaic species, such as Neanderthal and Denisovan.” | learn more
Concrete microbiome could act as early warning system for collapse. “Concrete may not seem like a particularly hospitable environment for life, but bacteria do actually live inside it. A new study led by the University of Delaware has examined this concrete microbiome to find out how they get there, how they change over time, and how we might use them in future to monitor or even repair defects.” | learn more
thoughts of food 🍔
Is lab-grown meat really going to solve our nasty agriculture problem? “Long the stuff of science fiction and philosophical musing, cellular agriculture is fast becoming a reality.” | learn more
Plant-based Sushi, faux fish rattle the multibillion-dollar seafood market. “When a tuna marketing executive took a bite of the dehydrated tomato seasoned with olive oil, algae extract, spices, and soy sauce early last year, he was shook. “This is going to be a problem for us,” he said.” | learn more
Smallholders produce one-third of the world’s food. This is less than half of what many headlines claim. From Our World in Data: “It is often claimed that smallholder farmers produce 70% or even 80% of the world’s food. This claim has even been made by the United Nations Food and Agriculture Organization (UN FAO).” | learn more
big ideas 📚
We need to build our way out of this mess. “Many of our country’s problems are reducible, in one way or another, to the fact that we have lost the imperative to transform the physical world.” | learn more
The trillion dollar paint job. “Infrastructure spending is broadly popular, which is likely why this new “infrastructure” bill has a decent amount of bi-partisan support. This is also why so many projects that have nothing to do with infrastructure are framed in such dishonest terms.” | learn more
Have you hugged a concrete pillar today? From Bill Gates: “In 1950, the world made roughly as much steel as cement (a key ingredient in concrete); by 2010, steel production had grown by a factor of 8, but cement had gone up by a factor of 25.” | learn more
on the blockchain ⛓
