Listen to the beat: Behavioral and neurophysiological correlates of slow and fast heartbeat sounds.

Background: Listening to heartbeat sounds have been found to affect cardiac activity and behavior. However, less is known about the effects of these stimuli on brain activity and cognition. Alpha oscillations (8-13 Hz) are considered markers of cortical activation.

Using Single-Species and Whole Community Stream Mesocosm Exposures for Identifying Major Ion Effects in Doses Mimicking Resource Extraction Wastewaters.

Wastewaters and leachates from various inland resource extraction activities contain high ionic concentrations and differ in ionic composition, which complicates the understanding and effective management of their relative risks to stream ecosystems. To this end, we conducted a stream mesocosm dose-response experiment using two dosing recipes prepared from industrial salts. One recipe was designed to generally reflect the major ion composition of deep well brines (DWB) produced from gas wells (primarily Na, Ca, and Cl) and the other, the major ion composition of mountaintop mining (MTM) leachates from coal extraction operations (using salts dissociating to Ca, Mg, Na, SO and HCO)-both sources being extensive in the Central Appalachians of the USA.

Assessing the health, social, educational and economic impact of the COVID-19 pandemic on adolescents in low- and middle-income countries: a rapid review of the literature.

COVID-19 has caused profound health, social, educational and economic devastation around the world, especially among the lives of adolescents in low- and middle-income countries. This paper looks at a wide array of outcomes impacting adolescents' daily lives including health (mental, physical, sexual and reproductive health, vaccine perceptions and overlap between these topics), social relationships (family and peer), education and socio-economic disparities. Both scientific and grey literature between December 2019 and February 2022 were sought from PubMed, Google Scholar and organisations conducting research among adolescents, and coded.

COVID-19, state (in)visibility and structural violence in low- and middle-income countries.

The socioeconomic impact of COVID-19 on adolescents and youth in lower- and middle-income countries (LMICs) who have migrated for work, are among the urban poor, or have been forcibly displaced is not well understood. To address this knowledge gap, this article draws on in-depth qualitative interviews undertaken between April and July 2020 with 249 adolescent girls and boys and 24 community key informants in Bangladesh and Ethiopia. These two countries have divergent social protection systems and thus provide a useful comparative lens to understand state provisioning for the most disadvantaged, including vulnerable young people, in crisis contexts.
