He promised his paralyzed wife they would die on the road together, not in a hospital

Happy Tuesday. Today's lead story is about a retired Chinese military officer and his paralyzed wife who decided in 2014 they would rather die on the road than in a hospital. They've now visited 31 of 33 Chinese provinces. She is, by his account, 100 times more spirited than before.

We also have a NASA engineer who designed a waterless toilet for astronauts and realized it solved the same problem for a billion people without plumbing, California joining 30 states requiring personal finance in every high school, and a small dog named Teddy rescued from a ravine on England's third-highest peak after three weeks alone.

Dive in.

Liu Peijin and his wife had dreamed since their wedding of a grand road trip across China. His long military career got in the way, and then her diabetes did something worse, leaving her partially paralyzed on her left side. When it became clear that a hospital bed was where most people in her situation ended up, they made a different choice. "We would rather die on the road than in a hospital bed."

They set out in 2014 across coastal Jiangsu and Zhejiang provinces, their daughter objecting, the outcome uncertain. What happened instead was that the movement rejuvenated her. Liu converted a car into a camper van with two beds, a kitchen, a dining table, and a full supply of medical equipment. He became her full-time nurse, managing her rehabilitation exercises, her medications, and her daily foot soaks for diabetes. "She is 100 times more spirited than she was before," he said.

They have now visited 31 of China's 33 provinces. In 2017 in Hubei Province, local staff volunteered to carry her wheelchair across a scenic area she couldn't otherwise reach. Liu says he treasures that kind of help and tries to stay in touch with everyone who offers it. Despite her paralysis, she has avoided muscle and joint atrophy, maintained her coordination, and can communicate largely as before.

"We would rather die on the road than in a hospital bed." They meant it as a joke, almost. More than a decade later, it turned out to be the best medical advice anyone gave her. Read the full story.

Diana Yousef was working at NASA on the problem of sanitation in space when something clicked. The requirements for a toilet that functions without running water or sewage infrastructure are the same whether you are on a space station or living in a rural community beyond the reach of plumbing. About one billion people worldwide fall into that second category.

The result is the iThrone, a waterless toilet that rapidly evaporates 95% of the water content of human waste, making safe disposal possible anywhere it can be deployed. No pipes, no sewage system, no connection to any grid. The units can be trucked or dropped into any environment where sanitation infrastructure doesn't exist, and are already serving approximately 20,000 households across Uganda, Panama, and the United States.

Yousef, who holds degrees from Cornell, Columbia, and Harvard, won the 2026 Global Citizen Waislitz Award for her work, which comes with $100,000 to help her startup change:WATER scale the technology to millions more households. "Safe, sustainable sanitation for everyone, everywhere," she said, "is the goal." Read the full story.

Starting in the fall of 2027, every public high school student in California, including charter school students, will be required to complete a one-semester personal finance course before graduating. The course covers 13 topics: banking, credit scores, loans, income taxes, investing, insurance, spotting scams, budgeting, and college financing, among others. California's legislation passed in 2024 and is now moving into implementation.

"Saving for the future, making investments, and spending wisely are lifelong skills that young adults need to learn before they start their careers, not after," said Governor Newsom. Fresno Unified, the state's third-largest district, has been pioneering the course since 2023 and reports that the classes are among the most sought-after electives in the district.

California joins a national movement led by the nonprofit Next Gen Personal Finance and its Mission 2030 Fund, which has committed 30 states to mandatory financial literacy courses, with 11 already fully implementing them. Read the full story.

Teddy went missing on August 2nd while hiking on Helvellyn in the Lake District, the third-highest peak in England. His owner searched, put up posters, and waited. Three weeks passed with no sightings. Then on August 21st, volunteers in the area heard barking coming from Dry Gill, a steep and difficult ravine on the mountain's slopes.

Teddy was alive but stuck and unreachable. The Keswick Mountain Rescue Team was called in, seven members responded, and the operation took three and a half hours. He was secured in a rucksack for the journey down, given a small amount of food, and reunited with his owner in the car park at the base of the mountain.

He had lost considerable weight but had no obvious injuries. He was taken to a vet, and by all accounts was otherwise in remarkable shape for a small dog who had just spent three weeks alone on one of England's most challenging peaks. Read the full story.

On August 25, 1939, The Wizard of Oz opened in movie theaters across the United States. The film's use of Technicolor, its fantasy storytelling, its unforgettable characters, and its timeless songs made it an immediate sensation. It was built around a simple premise of self-discovery, beautifully captured in two of cinema's most iconic lines: "If I ever go looking for my heart's desire again, I won't look any further than my own backyard," and "There's no place like home."

It didn't become a cultural institution overnight. Reviews were strong but the film struggled at the box office initially, only finding its full audience 20 years later when CBS began broadcasting it annually on television. Families waited all year just to see it again. It became the most watched film in motion picture history.

Other notable August 25 events:

2003: NASA launched the Spitzer Space Telescope, 23 years ago today, the first infrared observatory to use an Earth-trailing orbit, which later became the first telescope to directly capture light from exoplanets and discovered an additional ring of Saturn.

1916: The National Park Service was created in the United States, 110 years ago today, establishing the framework that would eventually govern 63 national parks.

1609: Galileo Galilei demonstrated his first telescope to Venetian lawmakers, 417 years ago today, who could suddenly see distant ships two hours earlier than anyone else and doubled his salary on the spot.

1944: Paris was liberated from four years of Nazi occupation, 82 years ago today, as French resistance forces and Allied troops entered the city, the tricolor was raised on the Eiffel Tower, and Charles de Gaulle made his triumphant entry into the capital.

Every day brings amazing advances and uplifting moments that remind us just how wonderful the world can be. Here are five reasons why today is the best time ever to be alive:

🔬 Wind Power From the Sky: Companies are testing kite-like airborne systems that fly at altitudes where winds are far stronger and more consistent than at ground level, generating electricity from a resource that conventional turbines simply cannot reach, with several systems now producing power commercially.

⚛️ Fusion Power Is No Longer Science Fiction: Small modular fusion reactors being built by private companies using new magnet and plasma confinement designs are expected to achieve net energy gain this decade, with several targeting commercial grid power by the early 2030s for the first time in history.

🌱 Chocolate and Vanilla Without the Rainforest: Biotechnology companies are growing cocoa and vanilla flavors directly from plant cells in fermentation tanks, producing chemically identical flavors to the originals without any tropical agriculture, deforestation, or the supply chain vulnerabilities that currently make both ingredients expensive and precarious.

🔭 The Universe Hums With Gravitational Waves: Networks of millisecond pulsars distributed across our galaxy have now detected a gravitational wave background permeating the entire universe, produced by the mergers of supermassive black holes across billions of years of cosmic history, opening an entirely new window on the large-scale structure of time and space.

🌊 Bringing Life Back to Dead City Seawalls: Engineers in coastal cities are attaching textured panels to bare concrete seawalls that mimic the complex surfaces of natural rock pools, creating habitats that support rich communities of marine life in places where previously nothing could survive.
