Overcoming Shifting Baselines: Paleo-Behaviour Reveals Industrial Revolution as Tipping Point.

School of Science, Auckland University of Technology, Auckland, New Zealand.
Human activities have significantly altered coastal ecosystems worldwide. The phenomenon of shifting baselines syndrome (SBS) complicates our understanding of these changes, masking the true scale of human impacts. This study investigates the long-term ecological effects of anthropogenic activities on New Zealand's coastal ecosystems over 800 years using fish otolith microchemical profiling and dynamic time warping across an entire stock unit.

Objective: Reverse obliquity intertrochanteric fracture is an unstable type of fracture. Current guidelines recommend intramedullary fixation, but there are still complications such as screw removal, hip varus, nail withdrawal, and nail fracture. The objective of this study was to use finite element analysis to compare the biomechanical properties of the novel proximal femoral bionic nail (PFBN), proximal femoral nail antirotation (PFNA), and combined compression interlocking intramedullary nail (InterTan) in the treatment of reverse obliquity intertrochanteric fractures (AO/OTA 31-A3.

Department of Psychology, Faculty of Social Sciences, University of Macau, Macau SAR, China.
Objectives: Shift-and-persist coping strategies have been demonstrated to be beneficial for physical health of individuals in low socioeconomic status (SES); however, their impacts on psychological well-being remain less clear. This study aimed to examine: (1) whether the protective effects of shift-and-persist with respect to psychological well-being (i.e.

Fungi are well known for their ability to both produce and catabolize complex carbohydrates to acquire carbon, often in the most extreme of environments. Glucuronoxylomannan (GXM)-based gel matrices are widely produced by fungi in nature and though they are of key interest in medicine and pharmaceuticals, their biodegradation is poorly understood. Though some organisms, including other fungi, are adapted to life in and on GXM-like matrices in nature, they are almost entirely unstudied, and it is unknown if they are involved in matrix degradation.

Background: Exogenous double-stranded RNA (dsRNA) has the potential to serve as an effective alternative to conventional chemical pesticides for the control of insect pests, because it can specifically inhibit essential gene expression in these organisms. However, identifying suitable gene targets remains a crucial step in the development of RNA interference (RNAi)-based pest control strategies.
Results: In this study, three apoptosis-related genes were selected to evaluate their potential for RNAi-induced lethality in Henosepilachna vigintioctopunctata via foliar spray dsRNAs.
