Bhattacharjee and Schaeffer et al. map exclusive breastfeeding (EBF) in 94 low- and middle-income countries (LMICs), finding increased EBF practice and reduced subnational variation across the majority of LMICs from 2000 to 2018. However, only six LMICs will meet WHO’s target of ≥70% EBF by 2030 nationally, and only three will achieve this in all districts.

This study moves beyond technical estimates to assess the deployable rooftop solar potential across 367 Chinese cities, factoring in real-world constraints. The findings offer actionable insights to guide strategic deployment and support China’s ambitious solar energy goals.

This study shows that optimally sized nanocarriers reach Duchenne muscular dystrophy muscle primarily through transcytosis, where they can deliver tamoxifen to improve muscle health and strength in mice.

Oat is an important food crop, but the genetic diversity within the gene pool remains unclear. Here, the authors report the analyses of worldwide diversity and population structure of hexaploid oat, and identify signatures of structural rearrangements within the germplasm collection.

Polygenic scores for body mass index and obesity constructed using data from 5 million people with different ancestries were associated with distinct weight gain trajectories from early childhood to adulthood.

Cerebral palsy lacks reliable biomarkers for early and accurate diagnosis. Here, the authors show serum proteomic signatures of disease and develop a multi-biomarker diagnostic model.

Wastewater-based surveillance tends to focus on specific pathogens. Here, the authors mapped the wastewater virome from 62 cities worldwide to identify over 2,500 viruses, revealing city-specific virome fingerprints and showing that wastewater metagenomics enables early detection of emerging viruses.

Chronic care manages long-term, progressive conditions, while acute care handles short-term ones. Here, authors show chronic conditions account for most of the global health burden, with 68% of DALYs and 93% of YLDs attributed to chronic care needs.

Long COVID has heterogeneous presentation and clinical trajectories are not well defined. Here, the authors define trajectories using data from a prospective cohort study in the United States involving symptom questionnaires from acute infection up to 15 months.

Discoveries in Jurassic rocks reveal that birds were adept fliers earlier than scientists realized.

Offshore wind power may play a key role in decarbonising energy supplies. Here the authors evaluates current grid integration capabilities for wind power in China and find that investment levels should be doubled for 2030, and that long-term storage and transmissions are key to accelerated developments of offshore wind in 2050.
