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.

Switzerland builds the world’s largest water battery to store surplus renewable energy

Nant de Drance represents something genuinely exciting: proof that we can store renewable energy at a scale that changes how entire continents manage their grids. Tucked 2,000 feet inside the Swiss Alps, the plant holds 20 million kWh by moving water between two mountain reservoirs — absorbing surplus solar and wind, then releasing it as hydropower within minutes when demand spikes. It can supply roughly 900,000 homes and acts as a rapid-response buffer for Switzerland and neighboring European countries. Projects like this show that the hardest engineering problems in the clean energy transition are solvable.

Sand, for article on sand battery storage

World’s first commercial sand battery begins energy storage in Finland

Sand-based thermal energy storage is stepping out of the lab and into real communities, and the implications reach well beyond Finland. A steel tank packed with ordinary sand captures surplus wind and solar energy as heat, then pipes warmth through a district heating network serving homes and public buildings — at under €10 per kilowatt-hour, using no rare materials. With nearly half of Scandinavian homes already connected to district heating, this technology has a ready path to scale. For communities facing long, cold winters, affordable heat storage like this could become a quiet cornerstone of the clean energy transition.

Helicopter flying, for article on sustainable aviation fuel

Airbus flies first helicopter with both engines burning 100% green fuel for the first time ever

Sustainable aviation fuel just powered both engines of an Airbus H225 helicopter at the same time — a first for any rotorcraft, anywhere. Earlier tests had only run SAF in one engine at a time, so flying twin engines on 100% SAF marks a real leap toward proving the fuel works under the demanding, variable loads helicopters face. Airbus says SAF at full concentration can cut CO₂ emissions by up to 90% compared to conventional jet fuel, and the company is aiming to certify 100% SAF across its commercial aircraft and helicopters by 2030. For missions like search and rescue or medical evacuation, where batteries can’t yet deliver, this is one of the most promising paths to cleaner skies.
