Background: Mutualistic mycorrhiza fungi that live in symbiosis with plants facilitates nutrient and water acquisition, improving tree growth and performance. In this study, we evaluated the potential of mutualistic fungal inoculation to improve the growth and disease resistance of Scots pine (Pinus sylvestris L.) against the forest pathogen Heterobasidion annosum.

Article Synopsis
  • High-grade follicular cell-derived non-anaplastic thyroid carcinomas are rare tumors, particularly in patients under 21, and are more commonly diagnosed in older adults.
  • A study focused on 15 patients aged 9-20 revealed various classifications of thyroid carcinoma, including poorly differentiated and differentiated high-grade types, with specific genetic alterations noted, especially in the DICER1 and TP53 genes.
  • Immunohistochemistry tests indicated the presence of BRAF V600E mutations and PTEN alterations, highlighting the molecular complexity of these thyroid cancers in younger populations.

Article Synopsis
  • String figure games are a widely practiced cultural activity that can provide insights into how cultures share and develop cognitive practices over time.
  • Researchers analyzed 826 string figures from 92 societies using a unique knot theory methodology, identifying 83 common designs with varying geographic spread.
  • The findings suggest that the pattern of shared figures may indicate both innovation within cultures and potential ancient origins, highlighting the complexity of cultural transmission.

Improving bone-graft substitutes and expanding their use in orthopedic and spinal surgery leads to shorter surgical times, fewer complications, and less pain among patients both in human and veterinary medicine. This study compared an elastic porous β-tricalcium phosphate/poly(L-lactide-co-ε-caprolactone) (β-TCP/PLCL) copolymer scaffold (composite scaffold) and a commercially available β-TCP/PLCL bone-graft substitute (chronOS Strip) in a rabbit calvarial defect. A bilateral, 12-mm circular defect was created in the parietal bones of 12 rabbits.

This paper explores the role of measurement as a cognitive technology across human history, emphasizing the coexistence of formal and informal measurement systems. While standardized systems dominate contemporary culture and are well documented across large-scale societies of the past, this manuscript highlights the less explored domain of informal measurement practices that have been integral to daily life from the past to the present. Through the examination of body-based measurement systems and proportional heuristics, we demonstrate how these informal strategies were not merely precursors to formal standards but essential adaptive tools for solving everyday problems.
