Welcome to the week.
It’s still mid-August, which to me is the height of summer, but apparently the kids are already headed back to school, and someone told me the other day that “spooky season” is practically here, so shows what I know.
We’re working behind the scenes right now on an It’s Called Science glow-up that I’m excited to share with you soon! 👀
But for now, it’s business as usual, so let’s get to the news.
This Week
And more.
Have a great week,

✅ Fact Check
Which sector accounts for the largest share of global greenhouse gas emissions?
Last week, we asked: What percentage of the food produced globally each year goes to waste
The answer: About one third. 46% of you got it right! In the US alone, that’s 30-40% of the food supply, mostly rotting in landfills where it emits planet-warming methane.

⚡️ Climate change:
People with schizophrenia face a uniquely brutal combo of impaired thermoregulation, medication side effects, and social stigma that makes them the single highest-risk group for dying in extreme heat. (WIRED)
The federal government just paid $4 billion to “cancel” offshore wind projects that were already financially dead. Government efficiency is alive and well. (Heatmap)
🌏 Brazilian scientists are producing millions of special mosquitos in a lab, and then releasing them to help fight deadly tropical diseases that continue to spread as the world heats up. (The New York Times)
Coral polyps use tiny hair-like cilia to whip up their own oxygen currents, but past a certain water temperature the system backfires and the coral essentially ends up suffocating itself. (Quanta Magazine)
🦠 Health & Bio:
Turns out brain aging isn’t a slow, steady shrink like we thought. There’s a sudden midlife invasion where blood-derived immune cells hijack your brain’s original microglia, which might explain a lot about Alzheimer’s risk. (Ground Truths)
A new study says universal healthcare would save the US $1 trillion and 114,000 lives every year, by cutting drug prices, administrative bloat, and fraud, not from cutting care. (Yale School of Public Health)
Some context for why it’s so hard to find a doctor: primary care gets less than 5% of US health spending while burnout drives a third of primary care docs to quit. (Your Local Epidemiologist)
The claim that the COVID vaccine increases miscarriage rates is false. Actual, extensively replicated research says COVID vaccination during pregnancy is not linked to increased miscarriage risk. (The 19th)
💦 Food & Water:
The cyclospora outbreak tied to Mexican-grown lettuce is pushing Black families to support Black-owned local farms they trust, turning a food-safety scare into a moment for rebuilding food sovereignty. (Capital B)
Are AI data centers really that bad for your local water? It depends — but some hyperscale AI campuses can slurp up to 5 million gallons a day, and the worst impacts often hit the small towns least equipped to handle them. (Gizmodo)
If we apply the logic that cleaned up smog and deforestation to animal welfare, as countries get richer, factory farming might get less brutal — if the sheer number of animals farmed didn’t keep swamping the gains. (Works in Progress)
🌎 Sick or miscarrying livestock waste all the feed, water, and land that went into raising them without producing any food, meaning healthier herds could be a genuine, underused climate lever. (The Conversation)
👩💻 Beep Boop:
AI Overviews have gutted click-through traffic so badly that major publishers are now planning as if Google traffic is already zero, leading to a slow, structural rewiring of how the internet works. (The Ringer)
Deepfakes get the headlines, but the real risk of AI in elections is embedded in voter rolls and ID-matching systems, such as the Indian algorithm that wrongly flagged voters for deletion at a 93% failure rate. (Rest of World)
At least 50 law enforcement officers have been caught misusing license-plate-reader networks like Flock to stalk women. (The 19th)
Google trained a model on 100,000+ hours of sign language data to let Deaf and hard-of-hearing users sign directly into their phone’s camera. (Silicon Angle)

Nature Has No Default Caregiver
We tend to assume that women do most of the caregiving in our society because nature made it that way.
But nature is full of countless examples that subvert that expectation, from poison dart frogs to owl monkeys.
This week, Karen Fischer explores what the animal kingdom reveals about gender, caregiving, and why flexibility — not biology — may be the whole point.

One of many mysterious, incomplete aspects of SimEnvironment was an editable database of chemicals.
An inside look at SimEnvironment, Maxis' long-lost toxic waste simulator
In 1992, computer game company Maxis spun off a business arm that would attempt to do for employees at oil companies and health insurance firms what SimCity had done for a generation of kids: Show them how complex systems function at a high level through pixelated, game-like simulations.
The small team behind Maxis Business Simulations generated numerous ideas but few actual games, leaving a breadcrumb trail of unfinished project titles scattered across contemporaneous news articles. But in recent years, a small community of Maxis fans and historians have helped bring these forgotten Sims into the limelight.
