Scientists hail autoimmune disease therapy breakthrough

Lupus remission in all five patients — that’s the striking result from a small German trial using CAR T-cell therapy, a treatment originally developed for blood cancers. Doctors collected each patient’s own T-cells, reprogrammed them to clear out the malfunctioning B cells driving the disease, and reinfused them. Months later, the patients’ immune systems had essentially rebooted: new B cells grew back, but they no longer attacked the body. None have needed lupus medication since. The lead researcher believes the same approach could help people with rheumatoid arthritis, multiple sclerosis, and other autoimmune conditions — opening a hopeful new chapter for millions worldwide who have long managed their illness without ever truly being free of it.

Hydrogen train, for article on hydrogen-powered trains

World’s first 100% hydrogen-powered trains begin operations in Germany

Hydrogen-powered passenger trains now cover an entire regional rail network in Lower Saxony, Germany — 14 Alstom Coradia iLint trains that have fully retired the diesel locomotives once used on the Cuxhaven-to-Buxtehude lines. Each train pulls oxygen from the air, combines it with hydrogen stored on the roof, and emits only water vapor, traveling roughly 1,000 kilometers between refuels. The regional operator has pledged to never buy another diesel train, citing both climate goals and the cleaner air passengers breathe at small-town platforms. It’s a modest fleet in a single corner of Germany, but it’s the first proof anywhere that diesel regional rail can be fully replaced — a template other countries with long, lightly used routes can now follow.
