Article Synopsis
- Climate change is causing shifts in animal habitats, particularly affecting the distribution of threatened marine species like whale sharks.
- Projections indicate that by 2100, whale sharks could lose more than 50% of their core habitat in some areas, with significant geographic shifts that could place them in closer proximity to large ships.
- The increase in whale shark interaction with shipping is expected to be dramatically higher under high emission scenarios compared to sustainable development, highlighting the urgency for better climate-threat predictions in conservation strategies for endangered marine life.
Background: Physicians often cite time as a limitation to performing a focused cardiac ultrasound (FoCUS) exam. The primary outcome of this study was to determine the amount of time to complete a quality FoCUS exam. Secondary outcomes evaluated time differences between different training levels.

Research funding systems fundamentally influence how science operates. This paper aims to analyze the allocation of competitive research funding from different perspectives: How reliable are decision processes for funding? What are the economic costs of competitive funding? How does competition for funds affect doing risky research? How do competitive funding environments affect scientists themselves, and which ethical issues must be considered? We attempt to identify gaps in our knowledge of research funding systems; we propose recommendations for policymakers and funding agencies, including empirical experiments of decision processes and the collection of data on these processes. With our recommendations, we hope to contribute to developing improved ways of organizing research funding.

This paper estimates associations of parent-reported neighbourhood and adolescent-reported home environments with SB among adolescents aged 11-19 years from 14 countries.
Methods: In the International Physical activity and the Environment Network (IPEN) Adolescent Study (an observational, cross-sectional multi-country study), adolescents wore a triaxial accelerometer for seven days that assessed sedentary time (ST).
Background: Digital food records offer efficiencies in collecting and assessing dietary information remotely; however, research into factors impacting their translation into clinical settings is limited.
Methods: The study examined factors that may impact the integration of digital food records into clinical dietetic practice by assessing (1) the source and rate of data errors received, (2) the impact of dietitian-adjusted data on dietary variables and (3) the acceptance of use in a complex chronic condition cohort. Adults from specialist clinics enroled in a randomised controlled feasibility trial participated.
