Measuring trends in extinction risk: a review of two decades of development and application of the Red List Index.

The Red List Index (RLI) is an indicator of the average extinction risk of groups of species and reflects trends in this through time. It is calculated from the number of species in each category on the IUCN Red List of Threatened Species, with trends influenced by the number moving between categories when reassessed owing to genuine improvement or deterioration in status. The global RLI is aggregated across multiple taxonomic groups and can be disaggregated to show trends for subsets of species (e.

One-quarter of freshwater fauna threatened with extinction.

Freshwater ecosystems are highly biodiverse and important for livelihoods and economic development, but are under substantial stress. To date, comprehensive global assessments of extinction risk have not included any speciose groups primarily living in freshwaters. Consequently, data from predominantly terrestrial tetrapods are used to guide environmental policy and conservation prioritization, whereas recent proposals for target setting in freshwaters use abiotic factors.

Research and product development for Crimean-Congo haemorrhagic fever: priorities for 2024-30.

Crimean-Congo haemorrhagic fever (CCHF) is a widely distributed and potentially fatal tick-borne viral disease with no licensed specific treatments or vaccines. In 2019, WHO published an advanced draft of a research and development roadmap for CCHF that prioritised the development and deployment of the medical countermeasures most needed by CCHF-affected countries. This Personal View presents updated CCHF research and development priorities and is the product of broad consultation with a working group of 20 leading experts in 2023-24.

Health equity engineering: Optimizing hope for a new generation of healthcare.

Medical researchers are increasingly prioritizing the inclusion of underserved communities in clinical studies. However, mere inclusion is not enough. People from underserved communities frequently experience chronic stress that may lead to accelerated biological aging and early morbidity and mortality.
