Drawing from science capital research and applying current practice theory, this study sheds light on people's perceptions of science and science-related practices in their everyday lives. The study develops a practice theoretical approach to examine understandings and engagements embedded in socially shared everyday science-related practices. The analysis of 51 interviews with Finnish people aged 20 to 88 with varied educational and socio-economic backgrounds brings participants' voices into a discussion.

This study explored the distribution of macronutrients (Ca, Mg, Na, K) and lithogenic (Ba, Cr, Ni, Mn, Fe) and mining-related (As, Pb, Cd, Cu, Zn) toxic metalloids and metals (TMMs) in tomato (Solanum lycopersicum L.), and its effects on plant development, productivity, genotoxicity, and human health, using a soil affected by mine tailings (AS) and an unaffected control soil (CS). The chemistry of soils reflected their mineralogy, and Fe-Ti oxides, sulfides and sulfosalts were found to be the most significant reservoirs of TMMs.

Instability remains one of the most common indications for revision after total knee arthroplasty. To gain a better understanding of how an implant will perform in vivo and support surgeons in selecting the most appropriate implant design for an individual patient, it is crucial to evaluate the implant constraint within clinically relevant ligament and boundary conditions. Therefore, this study investigated the constraint of three different implant designs (symmetrical implants with and without a post-cam mechanism and an asymmetrical medial-stabilized implant) under anterior-posterior shear forces and internal-external rotation moments at different flexion angles in human cadaveric knees using a six-degrees-of-freedom joint motion simulator.

Significance: In the last years, time-resolved near-infrared spectroscopy (TD-NIRS) has gained increasing interest as a tool for studying tissue spectroscopy with commercial devices. Although it provides much more information than its continuous wave counterpart, accurate models interpreting the measured raw data in real time are still lacking.
Aim: We introduce an analytical model that can be integrated and used in TD-NIRS data processing software and toolkits in real time.
Inference of the demographic histories and selective effects of human gut commensal microbiota over the course of human history.

Despite the importance of gut commensal microbiota to human health, there is little knowledge about their evolutionary histories, including their demographic histories and distributions of fitness effects (DFE) of mutations. Here, we infer the demographic histories and DFEs for amino-acid changing mutations of 39 of the most prevalent and abundant commensal gut microbial species found in Westernized individuals over timescales exceeding human generations. Some species display contractions in population size and others expansions, with several of these events coinciding with several key historical moments in human history.
