\"Big Data\" is on the covers ofScience, Nature, theEconomist, andWiredmagazines, on the front pages of theWall Street Journaland theNew York Times.But despite the media hyperbole, as Christine Borgman points out in this examination of data and scholarly research, having the right data is usually better than having more data; little data can be just as valuable as big data. In many cases, there are no data -- because relevant data don't exist, cannot be found, or are not available. Moreover, data sharing is difficult, incentives to do so are minimal, and data practices vary widely across disciplines.Borgman, an often-cited authority on scholarly communication, argues that data have no value or meaning in isolation; they exist within a knowledge infrastructure -- an ecology of people, practices, technologies, institutions, material objects, and relationships. After laying out the premises of her investigation -- six \"provocations\" meant to inspire discussion about the uses of data in scholarship -- Borgman offers case studies of data practices in the sciences, the social sciences, and the humanities, and then considers the implications of her findings for scholarly practice and research policy. To manage and exploit data over the long term, Borgman argues, requires massive investment in knowledge infrastructures; at stake is the future of scholarship.

In Sweden, childhood overweight and obesity rates have risen significantly over the last decades, necessitating scalable interventions. The evidence-based Healthy School Start (HSS) program integrates school and family components to promote healthy habits and prevent overweight and obesity among children. The IMPROVE trial aimed to compare the effect of two tailored implementation strategy bundles (Basic and Enhanced) on fidelity to the HSS program. A hybrid type III cluster-randomized trial with two parallel arms was conducted in 45 schools (cluster) in three municipalities in Stockholm Sweden from August 2021 to June 2024. The program was implemented in two consecutive cohorts over two academic school years. Fidelity was measured with an adherence score (0-4) and parent's responsiveness (1-5) to the four intervention components (health brochure, motivational interviewing health talk, classroom module and type 2 diabetes risk test). Data were analyzed using mixed-effects linear and logistic regression models. A total of 946 parents and 655 children participated. Overall fidelity, assessed as an adherence score, was around 75%, with most components implemented as expected. The adherence score in the Basic bundle showed no significant difference compared to the Enhanced implementation strategy bundle (β = 0.01, p = 0.95, 95% CI: -0.24, 0.25). Two of four Enhanced implementation strategies, educational outreach visits and networking between school and primary health care, did not happen mainly due to lack of interest and time among personnel. Parents born within the Nordic countries had twice the odds (p < 0.001, 95% CI: 1.14-3.43) of completing the motivational interviewing health talk compared to those born outside the Nordics. Enhancing the Basic implementation bundle with additional strategies did not consistently improve adherence or responsiveness. However, improvements observed over time underscore the importance of targeted support during the initial implementation year. Additional motivational actions might be needed in schools with a high proportion of children whose parents are born outside the Nordic region. These findings highlight the complex interplay between context and implementation success, emphasizing the need to adapt strategies over time to optimize their effectiveness rather than merely adding more. Moreover, the essentially null findings also point to broader methodological challenges in implementation science, particularly how to prioritize among determinants, strategy selection and tailoring.

VO 2 max (maximal oxygen consumption), a validated measure of aerobic fitness, has been associated with better cerebral artery compliance and measures of brain morphology, such as higher cortical thickness (CT) in frontal, temporal and cingular cortices, and larger grey matter volume (GMV) of the middle temporal gyrus, hippocampus, orbitofrontal cortex and cingulate cortex. Single sessions of physical exercise can promptly enhance cognitive performance and brain activity during executive tasks. However, the immediate effects of exercise on macro-scale properties of the brain's grey matter remain unclear. We investigated the impact of one session of moderate-intensity physical exercise, compared with rest, on grey matter volume, cortical thickness, working memory performance, and task-related brain activity in older adults. Cross-sectional associations between brain measures and VO 2 max were also tested. Exercise did not induce statistically significant changes in brain activity, grey matter volume, or cortical thickness. Cardiovascular fitness, measured by VO 2 max, was associated with lower grey matter blood flow in the left hippocampus and thicker cortex in the left superior temporal gyrus. Cortical thickness was reduced at post-test independent of exercise/rest. Our findings support that (1) fitter individuals may need lower grey matter blood flow to meet metabolic oxygen demand, and (2) have thicker cortex.
