When Universal Music Group removed its catalog from TikTok, demand for its songs on Spotify fell, especially for viral tracks. The study also links lost TikTok exposure to less playlist inclusion, which may extend the decline in streaming demand.
A combined antibody-based test detected and quantified Legionella pneumophila in complex process-water samples while reducing total processing time. It also supported identification of important subtypes, although direct subtyping had limitations and the study used samples spiked with laboratory standards.
Chitosan scaffolds carrying two bone-related peptides improved bone-cell adhesion, growth and mineralization in laboratory tests. In vivo, scaffolds with both peptides supported greater cell colonization and reduced the thickness of fibrous tissue around the implant material.
A systematic review and meta-analysis of studies in people with multiple sclerosis estimated that neurogenic bladder affected 48.8% of participants overall. The estimates differed substantially between studies, so the result should be understood as a pooled estimate rather than a precise rate for every person with multiple sclerosis.
This systematic review examined experimental immune-cell therapies for pediatric brain tumors, combining preclinical animal studies with early clinical evidence. Animal studies reported antitumor activity for several targets, while small clinical programs reported some tumor regressions, stable disease, and treatment-related side effects that varied by delivery route. The findings are preliminary and do not establish a routine treatment for patients.
A study of 40 young cattle calves found that processed probiotics improved growth and several gut-health measures more than chlortetracycline or no supplement. Encapsulated and freeze-dried formulations also increased beneficial bacteria, reduced two potentially harmful bacteria and, for encapsulated probiotics, improved some immune measures.
Two different scandium treatments improved the cycling life of a layered sodium-battery cathode. After 100 cycles in sodium half-cells, capacity retention rose from 18.6% without the treatments to 67.8% with scandium inside the material and 75.4% with a scandium oxide coating.
A study of 167 autistic children found that language skills, amount of speech and meaningful language use do not always align. The results suggest that simple verbal or non-speaking labels can miss important differences between children.
This systematic review examined 19 human clinical studies involving 612 patients who received hyperbaric oxygen therapy for selected muscle, ligament, tendon, and bone conditions. Results were mixed: randomized studies did not find a significant benefit for exercise-related muscle damage or delayed muscle soreness, while studies of avascular necrosis and bone marrow edema more consistently reported improvements. The review does not establish that hyperbaric oxygen works for all musculoskeletal conditions.
Adding hazelnut or sweet chestnut trees to soybean farms reduced their modeled carbon footprint in a study from western Slovakia. But soybean yields fell by 61–83% in the tree-based systems, with chestnut systems showing the largest modeled climate benefit and hazelnut systems retaining higher soybean yields.
A full-round analysis of the SCAN-C cipher found that its unusual XNOR key mixing adds no security compared with XOR. The researchers also report that the specified 12-round design can be attacked in an analysis requiring around 2^55 chosen plaintexts and 2^69 encryptions.
In a large study of adults over 50 with type 2 diabetes in Taiwan, new dementia diagnoses were less frequent among people who started a GLP-1 receptor agonist than among matched people who started long-acting insulin. The study was observational, so it cannot determine whether the medicines caused the difference.
A 13-year study of 696 dementia-free adults found several distinct patterns of cognitive aging. Better cognitive trajectories were associated with faster walking, higher quality of life, more sports and mentally stimulating activities, and greater intake of plant-based foods.
Older workers in Sweden who experienced workplace violence or threats were expected to spend about half a year less in work after age 50 than unexposed workers. Bullying showed a similar association, but the evidence was not statistically significant.
A water-stable porous material revealed how it takes up atmospheric moisture, beginning with a strongly bound water molecule and proceeding through water layers. The nickel material also showed fast loading, regeneration at 60 °C or below and projected water productivity under simulated conditions.
