A one-time gene therapy infusion restored meaningful hearing in 9 of 12 children with profound inherited deafness, no implants required. One three-year-old went from near-total deafness to hearing in the normal range within weeks.
164 utility-scale clean energy projects came online in the US in a single quarter, up 45% on the year, pushing total clean capacity to about 388 gigawatts. The quarter included SunZia, the largest land-based wind project in American history.
Keith Thomas, completely paralyzed since 2020, regained hand movement and wrist sensation through brain implants paired with AI-decoded stimulation. Remarkably, the gains persisted more than two years after stimulation stopped.
A 3D-scanned, 3D-printed sleeve with magnetic sensors plus individualized AI decoded 19 hand gestures in real time for ten participants, including three amputees. It stayed accurate after 7,500 force cycles.
A portable hip exoskeleton offloaded about 30% of hip work for stroke survivors with hemiparesis, cutting walking effort 18%. Some gait gains persisted after the device came off.
Chicago scientists trimmed a section of rice's own ALKBH9 and ALKBH10 genes, no foreign DNA, and boosted harvests 20 to 25% with better drought and heat tolerance. Published in Nature Genetics.
The world installed a record 664 gigawatts of solar in 2025, pushing the global fleet past 3 terawatts, triple its size four years ago. Solar now supplies about 9% of all electricity generated on Earth.
A 2.1-pound knee robot that resists rather than assists movement helped six children with spinal muscular atrophy gain 130% quadriceps strength. All of them can now rise from a chair unassisted.
Grid battery installations jumped 48% to a record 112 gigawatts in 2025, ten times the 2021 level, as lithium-ion prices kept falling. Storage is finally catching up with the solar boom.
More than 20 million electric cars sold in 2025, a full quarter of all cars sold worldwide and a first-ever milestone. Emerging markets doubled their sales in a single year.
A Namibian pilot converted 80 tonnes of low-grade iron ore into direct-reduced iron using green hydrogen, unlocking ore grades conventional green-steel routes cannot touch.
KJ Muldoon was born with a fatal metabolic disorder and no treatment options. Six months later a bespoke CRISPR edit built for his exact mutation had him walking, talking, and eating protein safely, and his case pushed the FDA to create a faster path for personalized therapies.
