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.

Japan completes and begins operating world’s largest fusion reactor

By / / Good News For Humankind

Fusion energy just took a real step forward in Japan: JT-60SA, the largest experimental fusion reactor on Earth, has officially powered up in Ibaraki Prefecture. Standing six stories tall, it heats plasma to roughly 200 million degrees Celsius — hotter than the sun’s core — to study the same process that lights the stars. More than 500 scientists and 70 companies across Japan and the European Union built it together, and its job is to pave the way for ITER, the even larger reactor rising in France. Fusion still has a long road ahead, but moments like this remind us what becomes possible when nations pool decades of expertise toward a shared, emissions-free future.

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.

North Korea eliminates rubella

By / / Good news links

North Korea introduced a mass measles-rubella immunization program in November 2019. Through this mass immunization activity, achieving more than 99.8% coverage in almost 6 million target population, the country has rapidly built substantial population immunity for rubella.

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.

World’s first drug to regrow teeth enters clinical trials

By / / Good News For Humankind

A tooth regrowth drug has entered human clinical trials in Japan, offering a potential third option alongside dentures and implants. The treatment works by blocking USAG-1, a gene that acts as a natural brake on tooth development, freeing the body to grow new teeth on its own. Researchers confirmed the approach first in mice, then in ferrets, before moving to people, and a pediatric trial is planned for children with anodontia, a rare condition that leaves six or more teeth missing. Dr. Katsu Takahashi, who has chased this idea since 2005, hopes for regulatory approval by 2030. With oral disease affecting some 3.5 billion people worldwide, regrowing real teeth could reshape dental care far beyond Japan.
