A theory article proposes the concept of a “digital citizenship prerequisite” to describe how online public services may make access to social rights depend on people’s digital resources. It argues that this can weaken the welfare state’s universal reach in practice, especially for people with lower incomes, less education, older people and rural residents.
A questionnaire study of 146 people examined reactions to sixth-generation mobile networks that can sense people and their surroundings. Acceptance depended strongly on the setting and was linked more to trust, clear rules, transparency and user control than to sensing capabilities alone.
This clinical practice guideline updates earlier guidance on urinary tract infections in children from 8 days through 5 years of age. It reviews evidence and provides recommendations for evaluation, antibiotic treatment, imaging, and assessment of related conditions. The guideline reports that most key recommendations are based on low or very low certainty evidence.
A study found that cultivating Pyropia haitanensis improved water quality both where the seaweed grew and in connected aquaculture ponds. It also increased microbial diversity and changed which bacteria and other organisms were most common.
A study of Syrian refugees in the Netherlands finds that the ethnic makeup of the region where they were housed influenced whom they came to know. These effects on social contacts remained after five years, while the region’s level of urbanization showed no clear effect.
People with first-episode psychosis had glutamate levels that were correlated across several brain regions, unlike healthy comparison participants. The study did not find clear differences in glutamate concentration within any individual region, and the network-level findings were exploratory.
A systematic review examined clinical research on ambroxol in people with Gaucher disease and GBA1-related Parkinson disease. It found some reported biochemical and neurological changes in selected patients, but the studies were generally small, uncontrolled and varied substantially. The review concluded that ambroxol remains investigational and that its long-term safety and clinical effectiveness are uncertain.
Sublethal silver nanoparticle exposure changed the balance between Escherichia coli and Staphylococcus aureus in laboratory cultures. The shift depended on an E. coli pathway that released acetate and ammonium, which helped S. aureus survive.
Researchers report an as-cast organic solar cell with a power-conversion efficiency of 20.11%, or 19.69% in certified testing. The approach also produced devices with 15.12% efficiency over an area of 20.17 square centimeters, pointing to a simpler route for making larger solar cells.
This systematic review examined clinical, lung-function, imaging, and workplace findings in people diagnosed with artificial stone silicosis, an occupational lung disease associated with dust exposure during artificial-stone work. Across the reviewed reports, some patients had severe lung changes even when standard lung tests or chest radiographs did not detect early disease.
Researchers used a precursor additive called CGBA to control how wide-bandgap perovskite films formed. The resulting cell reached 21.43% efficiency, while an all-perovskite tandem reached 29.63%; unencapsulated target devices retained 93% of their starting efficiency after 4,500 hours in nitrogen.
A study of human lung epithelial cells found that chronic, low-dose inorganic arsenic exposure began changing cell metabolism within 48 hours—before cell transformation. The changes included more glutathione production, increased glycolysis and triglyceride buildup, patterns that also appeared after 24 weeks of exposure.
Researchers have updated Ocaña, Colombia’s map of areas prone to landslides and other slope failures. Among 581 sites in 46 neighborhoods, 78% showed active mass movement, mainly landslides and rockfalls.
A new analysis combining chromosome-level genomes from 103 bat species with fossils revises relationships among bat families. It indicates that bats, and therefore powered flight, probably originated in Europe in the late Palaeocene, while laryngeal echolocation predates the diversification of modern bats.
A scoping review examined nine studies published from 2005 through November 2025 on donor funding disruptions and paediatric HIV services in sub-Saharan Africa. The included studies linked funding transitions, particularly those involving PEPFAR, with health-system disruptions across several stages of children’s HIV care.
