Dialogic reading is not simply reading aloud. Developed originally by developmental psychologists in the late 1980s, the method transforms storybook time from a passive listening experience into an active dialogue between adult and child. The adult prompts the child with questions, encourages the child to name objects, expand on short phrases, and retell parts of the story, and then responds with feedback and praise. Over repeated sessions, the child gradually takes on more of the storytelling role while the adult shifts into the position of an attentive listener and gentle coach. The technique rests on a well-established theoretical foundation: children learn language best when they are actively producing it within responsive, socially meaningful interactions rather than merely absorbing it from a one-way stream of adult speech.

The research team, Erinç Ergenekon and Nesrin Işıkoğlu, set out to address a gap that has persisted in the literature. Dialogic reading has accumulated decades of evidence for boosting vocabulary, print awareness, phonological awareness, and other emergent literacy skills. A separate body of work has explored how picture books with mathematical content can introduce children to counting, comparison, size, and spatial concepts. But relatively few studies had asked whether combining the two—applying the dialogic method to carefully chosen math storybooks—could lift literacy and numeracy together in the same children. Given how tightly language and mathematics are intertwined in early development, the question carries real weight for anyone designing preschool curricula.

The study involved fifty-nine children, thirty-three boys and twenty-six girls, drawn from four preschool classrooms in a public school, along with their four teachers. The classrooms were randomly assigned to either an experimental or a control condition, with the two groups closely matched in average age: the experimental group averaged about 57.15 months, and the control group about 57.48 months, meaning the children were just under five years old. Over six weeks, teachers in the experimental classrooms read the same six math storybooks three times a week using the dialogic reading method. The control classrooms continued their usual activities without dialogic reading sessions or the math storybooks, providing a baseline against which the intervention’s effects could be measured.

The choice of books mattered. The six storybooks included translated classics by the illustrator Leo Lionni, such as Swimmy and Inch by Inch, works whose narratives naturally embed mathematical ideas. Inch by Inch, for instance, follows a little worm who measures the bodies of birds one inch at a time, inviting conversations about length, comparison, and counting. Stories like these give teachers organic openings to ask questions such as how long something is, which animal is bigger, or how many steps a character has taken. Rather than drilling arithmetic, the books weave quantity, measurement, and spatial reasoning into narrative contexts that young children find inherently engaging, allowing mathematical language to emerge through conversation rather than instruction.

When the researchers compared the two groups after the six-week intervention, the results were clear. Children who had experienced the dialogic reading sessions with math storybooks showed significantly greater gains in both early literacy and early math skills than their peers in the control classrooms. The literacy gains likely reflect the rich verbal interaction at the heart of the method: repeated questioning, expanded responses, and exposure to print concepts during shared reading are precisely the ingredients that meta-analyses have repeatedly linked to stronger emergent literacy. The math gains, meanwhile, suggest that the mathematical vocabulary and concepts embedded in the storybooks were effectively transmitted through the same conversational machinery, giving children practice with number words, comparative language, and quantitative reasoning in a naturalistic setting.

These dual-domain findings fit into a broader scientific picture that has been assembling for years. Large longitudinal studies have shown that children’s mathematical knowledge at school entry is one of the strongest predictors of later academic achievement, sometimes rivaling or exceeding the predictive power of early reading skills. Other research has demonstrated that language ability and mathematics achievement develop in a mutually reinforcing relationship, with meta-analytic evidence indicating that improvements in one domain feed growth in the other. Mathematical language in particular—words like more, less, longer, fewer, and next to—has emerged as a critical bridge, with intervention studies showing that deliberately cultivating this vocabulary causally improves children’s numeracy. A reading routine that simultaneously enriches general language and saturates conversation with mathematical terms is therefore well positioned to act on both fronts at once.

The practical implications are striking because the intervention is so accessible. It requires no special technology, no expensive curriculum package, and no restructuring of the preschool day. Teachers need a small set of thoughtfully selected math storybooks, training in the dialogic prompting techniques, and roughly three short reading sessions per week. The researchers note that this makes the approach attractive not only for educators but also for policymakers seeking scalable strategies to support foundational skills, particularly in public school settings where resources may be limited. Because the same routine supports literacy and numeracy simultaneously, it offers an integrated teaching method at a time when many curricula still treat the two domains as separate silos requiring separate instructional blocks.

The study also carries methodological significance. As one of the first quasi-experimental studies to examine the combined effects of dialogic reading on literacy and math outcomes in the same sample, it strengthens the case for a genuinely integrated model of early childhood instruction. The researchers acknowledge the study’s scope: the sample was drawn from a single public school, and the intervention lasted six weeks, leaving open questions about how the effects persist over longer periods and whether they generalize across different populations and educational systems. The data supporting the findings are available from the corresponding author upon reasonable request, and the study received no external funding. The authors report no conflicts of interest, and the work was approved by the Pamukkale University Ethics Committee with informed consent obtained from parents and participants.

For parents and teachers, the takeaway is refreshingly simple. The bedtime story and the classroom read-aloud are not just cozy rituals or literacy exercises; they are opportunities to build the architecture of mathematical thinking as well. By choosing books in which numbers, sizes, patterns, and measurements live naturally inside the story, and by asking children questions that invite them to talk, predict, explain, and retell, adults can turn twenty minutes with a picture book into a workout for two developing minds at once. In an era when school readiness gaps appear early and persist for years, evidence that such a modest, joyful practice can move the needle on both literacy and mathematics is news worth reading about—and, better still, reading aloud.

The tendon-bone insertion is one of the most architecturally demanding interfaces in the musculoskeletal system, representing a gradual transition in which tendon, fibrocartilage, calcified fibrocartilage, and bone are organized in a continuous gradient of composition, matrix organization, and mechanical stiffness. This intricate zonal arrangement enables efficient load transfer between compliant tendinous tissue and rigid mineralized bone while dissipating stress concentrations that would otherwise cause delamination or failure. When surgical repair reconstructs this junction, the healing process frequently substitutes this specialized transitional tissue with disorganized fibrovascular scar, which lacks the graded mineral content and matrix orientation necessary for durable mechanical coupling. This fundamental limitation explains the persistent clinical failure rates observed after anterior cruciate ligament reconstruction and rotator cuff repair, and it motivates the search for biomaterials that actively instruct regenerative processes rather than serving as passive space fillers.

Self-assembling peptide hydrogels have emerged as an exceptionally adaptable class of biomaterials for such applications. Because their assembly is driven entirely by noncovalent interactions, including hydrogen bonding, hydrophobic packing, and electrostatic complementarity, these systems can be engineered at the level of individual amino acids without introducing chemical crosslinkers that may provoke cytotoxicity or unpredictable degradation behavior. The octapeptide FEFEFKFK, previously developed by the same research group, self-organizes through antiparallel beta-sheet stacking under physiological pH, generating a three-dimensional nanofibrous network that mimics key structural features of the native extracellular matrix. The strategy of concatenating or branching these short self-assembling motifs, explored in the present work through the lysine-branched 17-residue peptide, illustrates a modular design philosophy in which the geometry of the supramolecular assembly, and not merely its chemical composition, becomes an independently tunable parameter.

The significance of topographical control in stem cell biology is well established in the broader literature on mechanotransduction. Cells interrogate their physical environment through focal adhesions, cytoskeletal tension, and downstream signaling cascades such as focal adhesion kinase and the YAP and TAZ transcriptional coactivators, translating surface features at the nanometer and micrometer scale into altered gene expression programs. Aligned grooves and fibers have repeatedly been shown to promote contact guidance, wherein cells elongate and migrate along the direction of the underlying pattern. For tenogenic differentiation in particular, cell elongation and anisotropic morphology appear to be potent instructive cues, since native tendon tissue is defined by highly aligned collagen fiber arrays and correspondingly elongated tenocytes interspersed between them.

A particularly noteworthy aspect of the study is the separation of topographical signaling from mechanical stiffness signaling. Many prior investigations of nanotopography on rigid substrates, such as titanium implants bearing grooved or honeycomb textures, have conflated geometric cues with the inherently stiff underlying material. Soft hydrogels more faithfully reproduce the compliance of native tendon and cartilage tissues, but patterning them has historically proven difficult because their weak mechanical networks often deform or collapse during fabrication. Demonstrating that a branched peptide can self-organize into aligned groove-like three-dimensional architectures spontaneously, without lithography, molding, or crosslinking agents, therefore represents a methodological advance that could be extended to other template-free biomaterial systems.

The immunological dimension of the work adds an important layer of relevance to the field of regenerative medicine. Macrophages are central orchestrators of the post-implantation inflammatory response, and their phenotype at the injury site profoundly influences whether healing proceeds toward productive tissue formation or toward chronic fibrosis. The pro-inflammatory M1 phenotype is associated with elevated tumor necrosis factor alpha, interleukin-1 beta, and destructive matrix remodeling, whereas the reparative M2 phenotype secretes interleukin-10 and growth factors that support matrix deposition, vascularization, and resolution of inflammation. The observation that the aligned nanotopography of Lys-SAPHs biases macrophage polarization toward the M2 phenotype aligns with prior reports that elongated cell morphology, induced on grooved or anisotropic surfaces, can itself shift macrophage activation states through cytoskeletal and nuclear mechanics.

This immunomodulatory mechanism carries particular weight in the context of tendon-bone healing because the early inflammatory phase largely determines the quality of the eventual enthesis. Excessive or prolonged inflammation promotes scar formation and fibrous interposition at the interface, undermining the graded tissue transition required for load bearing. By combining direct guidance of tendon stem cells and bone marrow mesenchymal stem cells with indirect enhancement of the regenerative milieu through macrophage polarization, the material engages multiple cell types simultaneously, which mirrors the multicellular coordination demanded by natural insertion development during embryogenesis.

The selection of the mixing ratio FEK17 to FEK8 at one to six as the optimal formulation reflects a structure-function relationship that deserves emphasis. Altering the relative abundance of the branched peptide changes the supramolecular packing and consequently the geometry of the self-assembled architecture, while oscillatory rheology confirmed that the storage modulus and viscoelastic behavior were preserved across the formulation series. This independence of topography from bulk mechanics is scientifically valuable because it permits the attribution of observed cellular responses specifically to surface geometry rather than to confounding changes in substrate compliance, a distinction that has complicated interpretation in many prior biomaterial studies.

The rat tendon-bone dual-defect model employed in the study provides a preclinical assessment that captures several clinically relevant outcomes. Micro-computed tomography quantification of the residual bone defect area offers a three-dimensional, non-destructive measure of osseous regeneration, while the Achilles functional index provides a behavioral readout that integrates muscle force, gait symmetry, and tendon-bone integrity into a single functional metric. Histological evidence of increased fibrocartilage formation is arguably the most meaningful endpoint of all, since the reconstitution of a fibrocartilaginous transition zone, rather than a direct, abrupt tendon-to-bone union, is the hallmark of authentic enthesis regeneration and the principal goal of interface tissue engineering.

The use of RNA sequencing to delineate the mechanisms underlying the optimized hydrogel’s effects exemplifies the current trend toward transcriptomic profiling in biomaterials research. Unbiased gene expression analysis can reveal unexpected pathways activated by topographical cues, extending beyond the canonical integrin and cytoskeletal axes to encompass metabolic reprogramming, epigenetic remodeling, and paracrine signaling networks. Such mechanistic depth not only strengthens causal interpretation of the observed phenotypes but also identifies candidate molecular targets that could be therapeutically augmented in combination strategies.

From a translational standpoint, peptide hydrogels offer several practical advantages. They are assembled from short synthetic sequences that can be produced at scale with high purity, their degradation products are amino acids with minimal immunogenic risk, and their aqueous assembly conditions allow the encapsulation of sensitive payloads such as growth factors, small molecules, or living cells. Hemocompatibility testing in the present study, which demonstrated that the branched formulations did not compromise blood compatibility relative to the pristine hydrogel, addresses a critical safety consideration for any material intended for implantation into vascularized surgical sites.

The broader conceptual contribution of the work lies in reframing surface topography as an active therapeutic parameter in soft tissue interface regeneration rather than a passive design feature. The finding that nanotopographical cues alone, delivered on a soft hydrogel without alterations in mechanical strength or chemical composition, were sufficient to enhance cell proliferation, migration, lineage commitment, immune polarization, and ultimately functional repair, underscores the potency of purely physical instruction in stem cell fate determination. This principle resonates with developmental biology, where graded physical environments of the native enthesis guide the spatially patterned differentiation of progenitor populations during growth.

Future investigations will likely need to address the durability of the topographical cue over the extended time course of enthesis maturation, since self-assembling peptide networks gradually remodel and degrade in vivo, and the alignment features may relax as the material resorbs. Quantitative comparisons of the groove dimensions, spacing, and orientation against the native collagen architecture of the developing insertion would further refine the biomimetic rationale. Scaling the platform to larger animal models with biomechanically demanding insertion sites, and integrating the topographical hydrogel with established augmentation devices such as suture anchors or interference screws, represents the logical next phase toward clinical evaluation.

For the field at large, the study supplies a concrete demonstration that the molecular design language of self-assembling peptides is rich enough to encode three-dimensional anisotropic architectures, not merely isotropic nanofibrous networks. The branching strategy introduced through the lysine residue, which joins two tandem self-assembling motifs and redirects their supramolecular aggregation into aligned grooves, is a design rule that other laboratories can adapt to peptide amphiphiles, elastin-like polypeptides, and other programmable biopolymers. As regenerative medicine moves toward instructive, cell-directed materials, the convergence of controllable nanotopography, immunomodulation, and mechanical fidelity demonstrated here offers a template for engineering functional interfaces throughout the body, from ligament reconstructions to cartilage borders and myotendinous junctions.

In synthesis, the work bridges a persistent gap between the well-documented power of topographical cues on hard substrates and the practical challenge of delivering those cues on soft, clinically compatible hydrogels. By achieving aligned groove-like nanostructures through rational peptide branching, preserving mechanical integrity and hemocompatibility, and validating efficacy through cellular, transcriptomic, and preclinical functional evidence, the researchers have articulated a coherent and reproducible strategy. The lysine-branched self-assembling peptide hydrogel platform thus stands as both a practical candidate for tendon-bone insertion repair and a methodological framework for the deliberate design of nanotopographical instruction in the next generation of regenerative biomaterials.

The research examined 3,943 participants who took part in the Age 46 Biomedical Sweep of the 1970 British Cohort Study. Just over half, 53.3 percent, were female, and all participants included in the analysis had the relevant activity, behavior, cognitive and background data. The cohort follows people born in Britain in 1970, allowing researchers to study health and behavior in a population reaching midlife at the same period. The investigators focused on four sedentary behaviors: reading, internet use, playing video games and watching television. They classified the first three as more cognitively active activities and television viewing as a more cognitively passive activity. This distinction was not intended to imply that every individual engages with media in the same way. Reading can range from challenging nonfiction to light material, internet use can involve learning or passive scrolling, and games vary widely in complexity. The categories were broad behavioral measures, but they offered a way to test whether different kinds of sitting were linked to cognition rather than treating all sedentary time as one uniform exposure.

To measure movement, participants wore activPAL3 accelerometers, devices designed to distinguish body positions and record physical activity. The researchers also collected self-reported estimates of time spent in the specified sedentary activities. Cognitive performance was assessed using three tests that sample different mental abilities. An auditory verbal learning test involving 10 words evaluates verbal learning and memory by examining how well a person can acquire and recall information. A category verbal fluency test asks participants to name animals, providing a measure influenced by language retrieval, semantic memory and executive control. A two-letter cancellation task measures aspects of attention and processing speed, requiring participants to identify target items efficiently among distractors. Scores from the assessments were standardized as z-scores and combined into a global cognition score, the study’s primary outcome. Standardization places results from different tests on a common scale, allowing them to contribute to a composite measure despite having different scoring systems.

The statistical analysis used linear regression models to estimate how an additional hour per day of each activity was associated with cognitive scores. The models adjusted for sex assigned at birth, moderate-to-vigorous physical activity, occupational physical activity and educational level. These adjustments are important because cognitive scores and daily routines can be related to factors other than the activity under investigation. Education, for example, may be associated with both the kinds of leisure activities people choose and their performance on cognitive tests. Occupational activity and exercise could also influence the amount of time available for sitting and may be related to health. The researchers additionally conducted sex-stratified analyses, examining associations separately by sex. Because the study was cross-sectional, however, the measurements of behavior and cognition represented the same broad period. Regression can identify patterns of association after accounting for measured covariates, but it cannot establish which behavior came first or whether an unmeasured factor affected both.

Reading showed the clearest association among the sedentary activities studied. In adjusted pooled models, each additional hour per day of reading was associated with a 0.042 standard-deviation higher global cognition score, with a standard error of 0.008 and a 95 percent confidence interval from 0.026 to 0.058. The false discovery rate-adjusted probability value was below 0.001. Internet use was also positively associated with global cognition, although the estimated relationship was smaller: each additional hour per day corresponded to a 0.017 standard-deviation higher score, with a standard error of 0.006 and a 95 percent confidence interval from 0.005 to 0.029. Its adjusted probability value was 0.030. These estimates describe differences between people with different reported activity patterns; they do not predict how much an individual’s cognition would change after deliberately adding an hour of reading or internet use. The size of an association can also be influenced by measurement accuracy, the kinds of content people choose and the social or educational circumstances surrounding those activities.

The two other behaviors did not produce statistically significant associations with global cognition. Television viewing had an estimated coefficient of minus 0.006 standard deviations per additional hour per day, with a standard error of 0.005 and a 95 percent confidence interval ranging from minus 0.017 to 0.004. The false discovery rate-adjusted probability value was 0.297, meaning the analysis did not provide strong evidence of a relationship in either direction. Video game playing had an estimated positive coefficient of 0.015, with a standard error of 0.009 and a confidence interval from minus 0.002 to 0.032; its adjusted probability value was 0.128. The result therefore did not meet the study’s threshold for a statistically significant association. A non-significant result is not proof that an activity has no cognitive relevance. It may reflect limited time spent on the behavior, substantial variation in the types of games or imprecise self-reporting. It does mean that, within these data and models, the researchers could not distinguish the observed estimates reliably from chance variation.

Physical activity showed a separate and important pattern. Moderate-to-vigorous physical activity was positively associated with global cognition after adjustment, with an estimated coefficient of 0.069 standard deviations for each additional hour per day. The standard error was 0.021, the 95 percent confidence interval extended from 0.027 to 0.110, and the false discovery rate-adjusted probability value was 0.009. This result supports the study’s broader interpretation that replacing a sedentary lifestyle with more movement may be relevant to cognitive health. Yet the analysis does not establish that exercise directly improved the participants’ test scores. People who engage in more vigorous activity may differ in sleep, health, income, social contact, stress, diet or other characteristics that were not fully captured by the available adjustments. The study also did not conclude that cognitively engaging sitting compensates for insufficient physical activity. Rather, its conclusion presents two potentially complementary ideas: accumulating moderate-to-vigorous activity remains a priority, while the composition of unavoidable sitting may also be worth considering.

The biological explanation for the findings remains open. Reading commonly requires sustained attention, visual processing, language comprehension, working memory and integration of information across sentences or pages. Depending on the task, internet use can involve searching, evaluating sources, navigating interfaces, learning and making choices. Such repeated mental operations could be markers of cognitive engagement, but the study did not measure the neural activity or learning processes produced by any particular book, website or online session. People with stronger cognitive abilities may also be more likely to choose reading or intellectually demanding online activities, creating the possibility of reverse causation. Early differences in education, occupational opportunities or lifelong reading habits could influence both activity choices and later test performance. The single assessment of behavior likewise cannot show whether long-term exposure matters more than current routines. Longitudinal studies, repeated cognitive testing and more detailed measures of content and context will be needed to determine whether changing sedentary behaviors alters cognitive trajectories.

For now, the results offer a qualified message for middle-aged adults and for researchers designing public-health advice. Sitting should not be treated as a single category when its cognitive consequences are being studied, but neither should the findings be converted into a prescription that reading or internet use guarantees sharper thinking. The evidence supports maintaining or increasing moderate-to-vigorous physical activity and suggests that cognitively active pursuits may be preferable ways to occupy some sedentary time. Future research could test whether associations persist over years, differ across cognitive domains or vary according to the intensity and purpose of digital use. It could also examine whether short periods of movement interrupting sitting provide benefits beyond total daily activity. Because the current analysis used observational, cross-sectional data, its strongest contribution is to identify a pattern for further testing: among adults in midlife, reading and internet use were linked with better global cognitive scores, while television and video games were not. The pattern is intriguing, but experiments and longitudinal evidence are required before it can be considered causal.
