A Chinese research team has achieved a breakthrough in treating Duchenne muscular dystrophy (DMD), a severe and rare hereditary disease, with its newly developed RNA editing technology LEAPER, marking the first time a China-developed RNA editing tool has entered clinical trials and the first global use of RNA editing for DMD. The LEAPER system components can precisely locate the erroneous genetic "blueprint" in muscle cells, restore the gene by removing specific sequences, and enable cells to produce functional proteins according to the corrected "blueprint," helping muscles regain vitality. Unlike traditional methods, it does not require delivery of exogenous editing enzymes. In clinical trials, the candidate drug LE051 showed promising results, with all three treated pediatric patients demonstrating significant and sustained improvements in motor function over a one-year follow-up period. The study was published in the journal Cell.

A China-led international research team has discovered the world's deepest and largest collection of whale remains in the Diamantina Zone of the southeastern Indian Ocean—a site they call a "whale necropolis." Exploring a 1,200-kilometer stretch of the zone in 32 dives using China's manned deep-sea submersible Fendouzhe (Striver), the team found five active whale falls and 476 fossil sites at water depths ranging from 4,616 to 7,001 meters, including one site consisting of three beaked whale vertebrae at a depth of 6,789 meters—the deepest active whale-fall ecosystem ever recorded. The density of whale remains reached up to 759.5 individuals per square kilometer. Using strontium isotope dating, they confirmed that the fossils there date back at least 5.3 million years to the Early Pliocene. Published in the journal @Nature, the study extends the known depth record of whale falls from 4,200 meters to nearly 7,000 meters, providing a unique window into the early evolutionary history, paleoecology and population dynamics of ancient whales.

The world's largest transparent spherical neutrino detector located in south China's Guangdong Province released its first findings in the journal Nature Wednesday. The Jiangmen Underground Neutrino Observatory (JUNO) completed the high-precision measurement of two key oscillation parameters based on the analysis of valid data collected over 59 days from Aug. 26 to Nov. 2, 2025. The measurement accuracy reduced the associated uncertainties by a factor of 1.6 compared to the combined experimental results in the past decades. The reviewer of Nature commented that these results not only validate the detector performance and analysis methodology, but also establish JUNO as a key player in the emerging precision era of neutrino oscillation physics, with direct implications for tests of the three-flavor paradigm, global oscillation fits, and future determinations of the neutrino mass ordering.
