The feel-good story of the day

The driver who used his own car as a guardrail

On Tuesday, drivers on I-5 near Fife, Washington watched an SUV smash into the concrete barrier again and again, and it was quickly clear the driver wasn't distracted, something was seriously wrong. Paul Jackson, a driver from Roy, Washington, pulled alongside and saw a woman behind the wheel with her eyes rolled back and a frightened young boy strapped into a car seat behind her.

He didn't wait for someone else to act. Jackson eased his Kia Forte up against the SUV and gently steered it into the barrier until it rolled to a stop, then rushed over, shifted the car into park, and got the child out safely before police and paramedics arrived.

"It was something I didn't really even think about. I just did it," he said. "Somebody had to do something." He was running late to pick up his wife's birthday cake, so he texted her photos from the scene just to prove he wasn't joking. A stranger's instinct, and a few careful seconds of steering, turned a highway disaster into a story everyone walked away from.

A cheap, decades-old pill finally helps with long COVID fatigue

In a trial of 399 adults in Brazil who'd had crushing, unrelenting fatigue for at least 90 days after COVID, researchers randomly gave people fluvoxamine, metformin, or a placebo for 60 days 1.

Fluvoxamine, an antidepressant that's been on the market since the 1990s and costs almost nothing, won out: the statistical analysis found a 99 percent probability it beat the placebo. "This is an important step forward for patients who have been desperate for evidence-based options," said Edward Mills of McMaster University, the trial's senior author 1. It's one of the first medications in the world to show a real, measurable benefit for a symptom that has sidelined millions of people from work and family life with nothing to show for years of searching.

Every koala alive descends from a tiny band that survived a hidden apocalypse

By calculating the koala's mutation rate for the first time and combing through hundreds of genomes, a team from the University of Sydney and Texas A&M traced the species back 100,000 years, long before any human set foot in Australia 10.

What they found: a severe population crash during a brutal glacial period, one so complete that every koala on the continent today traces back to a single small surviving population. "The study rewrites the timeline for the koala's genetic history in Australia," said PhD student Toby Kovacs, who led the work 10. The animals came back from almost nothing, on their own, and repopulated eastern Australia.

Autism and social misunderstanding may not be about "reading people" at all

A study in Nature Mental Health, led by Shannon Cahalan at the National Institute of Mental Health, found that autistic and non-autistic people use remarkably similar strategies for figuring out what someone else likes 50.

The difference isn't in how well autistic people learn; it's that their own preferences tend to be more varied and less predictable to an outside observer, which makes them genuinely harder to guess, for anyone. That single fact, not some deficit in reading social cues, may explain a lot of the friction autistic and non-autistic people report in getting to know each other.

Congress passed the biggest housing law in 30 years, aimed at the "housing theory of everything"

On July 11, the 21st Century ROAD to Housing Act became law, after passing the Senate 85-5 and the House 358-32 63. It's the first major federal housing legislation in about 30 years, built around a simple idea: scarce housing is quietly driving inequality, slow growth, and even falling fertility, because where you can afford to live decides your job, your commute, your family size, your neighbors.

One estimate says building restrictions in just New York, San Francisco, and San Jose cost the US economy $8,775 per worker every year 63. Right now, a record 22.6 million renter households, half of all renters, spend more than 30 percent of their income on housing 63.

Self-driving cars are already dramatically safer, and the data is starting to pile up

Across 220 million real-world miles in Los Angeles, San Francisco, Phoenix, Austin, and Atlanta, Waymo vehicles have logged 94 percent fewer serious injuries, 82 percent fewer airbag deployments, and 93 percent fewer pedestrian injuries than matched human driving, according to a joint analysis with the insurer Swiss Re 67.

Roughly 37,000 to 40,000 Americans die in car crashes every year. This is large-scale, transparent evidence that driverless cars, within the areas they currently operate, are meaningfully safer than we are.

A dead hot dog factory is becoming a fusion reactor testbed

A startup called Realta Fusion is converting a shuttered Oscar Mayer plant in Wisconsin into a facility called Forge, set to begin testing in 2029 whether a fusion reactor can actually turn a profit by producing more electricity than it consumes 76.

The company's device, nicknamed WHAM, already pulled off something new: generating electricity by extracting it directly from charged particles in the plasma, rather than using heat to boil water and spin a turbine like every other reactor design 76. "From sausages to fusion," said CEO Kieran Furlong 76.

British lawmakers push to end animal testing approved "in the dark"

Twenty-seven UK MPs from Labour, the Greens, the Liberal Democrats, the SNP, and independents have backed a motion demanding an end to "blind approval" animal testing licenses, which let labs run categories of experiments without regulators reviewing the actual details 99.

New Freedom of Information data shows six such licenses were granted in just the first three months of 2026, authorizing more than 100,000 animals for use over the next five years 99. More than 20,000 people have contacted their MPs on the issue since the campaign group Animal Aid's exposé in April. "Behind every licence is a living creature," said MP Neil Duncan-Jordan, who introduced the motion 99.

A Buddhist teacher's simplest idea about love might be his most useful

Reflecting on the Zen teacher Thich Nhat Hanh's book How to Love, writer Maria Popova returns to his central claim: "understanding is love's other name" 134. Nhat Hanh illustrates it with an image worth sitting with: pour a handful of salt into a cup of water and it's undrinkable, but pour that same handful into a river and people can still draw water to cook and wash and drink.

"When our hearts are small, our understanding and compassion are limited, and we suffer," he wrote. "But when our hearts expand... we can embrace others" 134.
