China’s JAC Motors rolls out world’s first commercial lithium-free EV

By / / Good News For Humankind

Sodium-ion EVs just hit the road for the first time, with Chinese automaker JAC delivering its Yiwei hatchback to customers in January 2024 — the world’s first mass-produced electric car running on a battery made from one of Earth’s most abundant elements. The little urban hatchback offers about 157 miles per charge, plenty for daily commutes, and holds up better than lithium in cold weather. Because sodium is found in ordinary salt and spread across nearly every country, it sidesteps the supply bottlenecks and high costs that have kept EVs out of reach for many buyers. If the chemistry scales, it could open the door to affordable electric driving in places lithium has struggled to reach.

Human ear, for article on gene therapy for deafness

Chinese scientists develop novel gene therapy that allows deaf children to hear for the first time

By / / Good News For Humankind

Gene therapy has restored partial hearing in four out of five deaf children in a Shanghai trial, with each child regaining roughly 60 to 65 percent of typical hearing ability. The Fudan University team used a harmless virus to ferry a working copy of the otoferlin gene directly into the inner ear, where it began producing the protein these children had been missing since birth. Most had heard little or nothing their whole lives, so even partial hearing opens a window for spoken language to develop during early childhood. Parallel trials at Cambridge and Regeneron suggest the field is converging on a shared approach — a hopeful proof of concept that could one day extend to many more forms of inherited deafness.

Hong Kong courts rule in same-sex couples’ favor

By / / Good news links

Hong Kong’s Court of Appeals ruled in favor of two same-sex couples in separate cases involving their rights to own and rent public housing. While same-sex marriage is not legal in the city, the rulings follow other decisions that have firmly established same-sex couples’ rights to equal treatment under the law.

Pig embryo with human kidney, for article on pig-human chimera

Chinese researchers grow world’s first human organ inside a non-human animal

By / / Good News For Humankind

Human kidney tissue has been grown inside a pig embryo for the first time, with roughly half the cells in the developing kidney being human. Researchers in Guangzhou reprogrammed adult human cells, then injected them into pig embryos engineered to leave a “gap” where their own kidneys would form. The human cells moved in and self-organized into an early-stage kidney structure over 28 days of gestation. It’s not a transplantable organ, and real ethical questions remain about keeping human cells out of pig brains. But for the 100,000 Americans waiting for a kidney right now, this is a meaningful step toward a future where no one dies waiting.

Wind turbine, for article on offshore wind turbine

World’s largest wind turbine is now fully operational and connected off coast of China

By / / Good News For Humankind

A single wind turbine off China’s Fujian coast can now power roughly 36,000 homes — and it’s the largest ever connected to a grid. The MySE 16-260 stretches 260 meters across, wider than the Eiffel Tower is tall, with each rotation generating up to 34.2 kilowatt-hours of clean electricity. It’s built to withstand winds of 287 km/h, which matters in a stretch of sea where near-gale conditions blow more than 200 days a year. An 18-megawatt machine is already in the works, hinting at how fast this ceiling keeps rising. Each leap in turbine size makes offshore wind cheaper and more credible as a backbone of the clean energy transition worldwide.
