Transmission networks of long-term and short-term knowledge in a foraging society.

PNAS Nexus

September 2025

Department of Human Behavior, Ecology and Culture, Max Planck Institute for Evolutionary Anthropology, Deutscher Platz 6, Leipzig 04103, Germany.

Cultural transmission across generations is key to cumulative cultural evolution. While several mechanisms-such as vertical, horizontal, and oblique transmission-have been studied for decades, how these mechanisms change across the life course, beyond childhood, remains unclear. Furthermore, it is under-explored whether different mechanisms apply to distinct learning processes: long-term learning-where individuals invest time and effort to acquire skills-and short-term learning-where individuals share information of immediate use.

Sweating is a vital thermoregulatory mechanism in humans for maintaining thermal balance during exercise and exposure to hot environments. The development of models that predict sweat rate based on body temperature has been ongoing for over half a century. Here, we compared predicted water loss rates (WLR) from these models to actual observations collected during 780 participant-exposures in three independent laboratory-based experiments.

New Phytol

September 2025

State Key Laboratory of Nutrient Use and Management, College of Resources and Environmental Sciences, National Academy of Agriculture Green Development, China Agricultural University, Beijing, 100193, China.

Microbial nitrate ammonification is a crucial process to retain nitrogen (N) in soils, thereby reducing N loss. Nitrate ammonification has been studied in enrichment and axenic bacterial cultures but so far has been merely ignored in environmental studies. In particular, the capability of arbuscular mycorrhizal fungi (AMF) to regulate nitrate ammonification has not yet been explored.

Department of Orofacial Pain and Dysfunction, Academic Centre for Dentistry Amsterdam (ACTA), University of Amsterdam and Vrije Universiteit Amsterdam, Amsterdam, The Netherlands.

In dental practice, it regularly happens: a patient presents with a prolonged pain complaint where there appears to be no sign of tissue damage (any longer). Patients with chronic facial pain may be experiencing altered nociception. This is associated with processes of sensitization and impaired signal inhibition in the somatosensory system.

Objectives: Although the multifactorial nature of chronic pain is well established, research has predominantly examined isolated variables or singular pathways that may contribute to this condition. We use a complex systems perspective to examine the interplay of psychological factors in the context of chronic pain.

Methods: We analyzed two cross-sectional datasets (N=935 and 1366) collected at a pain clinic and rehabilitation center in Belgium from individuals primarily with musculoskeletal pain.

Extensive epidemiological research and the findings from one randomised controlled feeding trial (RCT) have shown associations between the consumption of ultra-processed foods (UPFs) and higher energy intakes. To date the specific properties of UPF foods and diets that may be responsible for driving higher energy intakes remain unclear. A comparison of the diets in the single RCT to date showed a significantly higher eating rate (g/min, ER) for meals in the UPF diet compared to those in the minimally processed diet.

Intergenerational transmission of problem behavior: Genetic and environmental pathways.

Dev Psychopathol

September 2025

Faculty of Behavioral and Social Sciences, Department of Pedagogy and Educational Sciences, University of Groningen, Groningen, the Netherlands.

Despite the growing body of research on the intergenerational transmission of problem behavior, there is a need for more integrative approaches that consider the interplay between genetic and environmental factors. This study uses unique longitudinal data from TRAILS (analytic sample = 2202), a prospective multiple-generation cohort study in the Netherlands to examine whether parents' problem behavior (parents' self-reported lifetime antisocial behavior and substance use, reported at mean age 40 years) predicts offspring problem behavior nearly two decades later (offspring self-reported aggression and delinquency at mean ages 29 and 32 years). In path analyses, independent and relative contributions of genetic (polygenic scores of parents and offspring) and environmental (harsh parenting) pathways were tested.

Multiple myeloma (MM) is an incurable blood cancer characterized by clonal bone marrow plasmacytosis, hypercalcemia, renal failure, anemia, and osteolytic bone disease. Approximately 20% of NDMM patients, not predicted to have high-risk disease at diagnosis, progress early, despite optimal induction +/- ASCT and lenalidomide maintenance, and are subsequently categorized as functional high-risk (FHR) disease. Standardized risk-stratification models incorporate biomarkers of tumor burden, existence of high-risk cytogenetics, with the presence/absence of plasma cell leukemia/extramedullary disease to attribute high-risk at diagnosis; however, depth/duration of response to novel agent-based induction (NA-IND) as dynamic markers of disease risk have not been defined.

Bacillus drives functional states in synthetic plant root bacterial communities.

Genome Biol

September 2025

Department of Biology, Plant-Microbe Interactions, Science for Life, Utrecht University, Utrecht, 3584CH, The Netherlands.

Background: Plant roots release root exudates to attract microbes that form root communities, which in turn promote plant health and growth. Root community assembly arises from millions of interactions between microbes and the plant, leading to robust and stable microbial networks. To manage the complexity of natural root microbiomes for research purposes, scientists have developed reductionist approaches using synthetic microbial inocula (SynComs).
