Physical activity guidelines commonly recommend that older adults engage in at least 150–300 min of moderate intensity aerobic activity each week, combined with muscle strengthening and balance training. Although this target is clear, measurable, and useful for public health monitoring, it may be insufficient when directly applied to community-dwelling older adults who are frail, multimorbid, socially isolated, digitally excluded, or constrained by unsafe environments and limited care resources. For these populations, the central challenge is not only whether they can meet a weekly exercise volume, but whether they can preserve the functional abilities needed for independent living, social participation, and active aging. This Perspective argues for moving exercise promotion for community-dwelling older adults beyond a narrow adherence-based view of the 150-min target and toward a function-oriented paradigm of active health. We propose an integrated framework that places functional preservation at the center, uses micro dose exercise as an accessible entry point, applies Behavior Change Techniques to translate recommendations into sustainable daily habits, embeds exercise within community life through social prescribing, and supports long-term participation through human and digital collaboration. This approach does not reject existing physical activity guidelines. Rather, it reframes them as flexible references that can be adapted to older adults’ heterogeneous bodily conditions, social contexts, and everyday routines. By shifting from exercise adherence to long-term functional integration, community-based exercise promotion can become more inclusive, equitable, and feasible for older adults who are most likely to be left behind by standard dose-based models.
Bioleaching offers a sustainable alternative to conventional metallurgy, but its application is limited by low leaching rates, inhibition by heavy metals, and prolonged adaptation. Here, we engineered Acidithiobacillus ferrooxidans, a model bioleaching microorganism ubiquitous in mining environments, by modulating intracellular bis(3′ −5′)-cyclic dimeric guanosine monophosphate (c-di-GMP) signaling to enhance biofilm formation, bioleaching efficiency, and arsenic tolerance. Overexpression of diguanylate cyclase genes AFE_1379, AFE_0053, and AFE_1373 produced engineered strains S-222, S-306, and S-651, respectively, with 1.7-, 2.5-, and 5-fold higher intracellular c-di-GMP levels than the control carrying the empty plasmid vector. Under arsenic-free condi tions, all engineered strains showed similar growth profiles, but S-306, at intermediate c-di-GMP (306.3 ± 28.1 μg mg−1), formed cytochrome-rich biofilms with low internal resistance and achieved the highest bioleaching efficiency. Under arsenic stress, S-651, at high c-di-GMP (651.4 ± 15.5 μg mg−1), developed polysaccharide-rich biofilms that enhanced arsenic tolerance, scorodite (FeAsO₄·2H₂O) precipitation, and bioleaching performance. Transcriptomic analysis confirmed these strain-specific gene expression patterns. These findings demonstrate that tuning intracellular c-di-GMP enables A. ferrooxidans to reprogram biofilm matrix composition for extracellular electron uptake and heavy-metal resistance, providing a synthetic biology strategy for environmentally friendly bioleaching and tailings recycling
Wisdom is theorized to regulate the ethical use of cognitive strengths, but empirical evidence for its moderating role remains limited and inconsistent. This research investigates whether wisdom guides the application of intelligence and creativity toward prosocial ends, using domain-consistent, humanistic assessments across two studies (N = 933). Study 1 employed performance-based measures to examine how state-level wisdom influences the prosocial deployment of social intelligence and real-life creativity in morally complex scenarios. Study 2 used self-report measures to explore trait-level associations among integrative wisdom, social intelligence, creativity, and social mindfulness. Across both studies, wisdom consistently moderated the link between creativity and prosociality: higher wisdom predicted either stronger positive associations (Study 2) or buffered against ethically problematic use (Study 1). In contrast, no consistent evidence was found that wisdom similarly guided the use of intelligence. These findings suggest that wisdom functions as a selective moral regulator, more effectively shaping the ethical expression of open-ended, generative capacities such as creativity than of structured, instrumental capacities such as intelligence. The results underscore the importance of aligning constructs within shared evaluative domains and provide preliminary empirical support for wisdom as a meta-capacity that channels value-sensitive strengths toward socially constructive ends.
High quality factor and sensitivity are critical to wireless sensors targeting small perturbation detection. Although introducing parity-time symmetric dynamics promises enhanced performance, the symmetric scheme often yields limited sensing behaviors. In particular, its implementation is hindered by the inherent difficulties in decoupling capacitance- and coupling strength–induced responses, the requirements of delicately matching and/or tuning both gain and loss, and the need of strong coupling strength. Here, we report a concept of critical point (CP)–based wireless sensors that do not rely on balanced gain-loss configurations, delivering ultrahigh quality factor with an extended interrogation distance. Owing to a sharp and deep reflection dip, the CP-based scheme can resolve the change in coupling coefficient down to 1.92 × 10−4 and features frequency-independent responses. Furthermore, the CP-based scheme allows for identification of tiny asymmetric capacitive perturbations as small as 2.5 × 10−5 without requiring active tuning of the other parameters under weak coupling. Critical-point wireless sensors with unbalanced gain and loss enable reliable and sensitive detection under weak coupling.
Although the term ‘intellectual tradition’ is frequently used, it is rarely clearly defined, leaving a vast and largely unknown space for multidimensional inquiry. This article explores how to find tacit intellectual traditions by drawing upon cross-cultural philosophical resources and proposing possible methodological directions for educational research. The main argument is that intellectual traditions can be tacit at both epistemological and ontological levels. Three Western theorists—Edward Shils, Michael Polanyi, and Michael Oakeshott—critically reflect on anti-traditionalism and objectivism since the Enlightenment. They contend that intellectual traditions, including the tradition of science, as tacit knowledge, play an important role in human knowing and action. Chinese philosophy also attaches great importance to the tacit dimensions of intellectual tradition particularly at the ontological level, as exemplified by the core concept of ‘Dao’. As a foundational assumption underlying the worldview in ancient China, Dao generated different ways of knowing in Confucianism, Daoism, and Zen Buddhism. Even today, it continues to shape how Chinese people interpret and transmit traditions. The philosophical comparison between East and West reveals the complexities inherent in intellectual traditions, which bring new opportunities for educational research. Incorporating diverse tacit intellectual traditions can help researchers better understand cross-cultural educational issues in teaching, learning, and research. For this purpose, we propose ethnoepistemology, ontography, and hermeneutics as potential methodological tools.
Heterogeneous reaction of sulfur dioxide (SO2) on mineral dust is known to be an important pathway for SO2 removal mainly resulting in sulfate formation in the atmosphere, and its kinetic and mechanism can be significantly influenced by the presence of trace gases, such as, O3, NO2 and H2O2. However, little is known about the role of carbonyl compounds, such as formaldehyde (HCHO), that plays in this reaction. In this study, we investigated the heterogeneous reaction of SO2 on mineral dust, in this case, α-Al2O3 and SiO2 particles, in the presence of HCHO at different RHs using a flow reactor coupled with transmission-Fourier transform infrared (T-FTIR). Infrared spectra show that hydroxymethanesulfonate (HMS) can be formed through the interaction of HCHO with adsorbed SO2 on mineral dust even under dry conditions. HCHO plays a double-edged role in the heterogeneous reactions of SO2 at different RHs. The presence of HCHO inhibits the adsorption of SO2 on particles under dry conditions by competing with surface active sites, while it facilitates the amount of SO2 uptake by particles (N) at high RH by providing addition pathway for SO2 conversion. This enhancement also significantly shortens the discrepancy in different heterogeneous reactivity of particles towards SO2. The N value for α-Al2O3 particles is 5.2 times larger than SiO2 particles for particles exposed to SO2 alone, but this increase factor drops to 1.6 in the presence of HCHO at 80% RH. These findings deepen the understanding of SO2 heterogeneous chemistry in the atmosphere and how it is affected by the coexistence of other trace gases.
