Although there is a growing scholarly interest in studying the engagement of expatriates in external voting in their countries of origin, conventional survey methods often fall short of accurately representing the perceptions and political participation of undocumented immigrants. Remedying this gap, researchers from Japan used respondent-driven sampling to assess the factors that influence the political participation of undocumented Mexican immigrants residing in the US in Mexican elections.
A 6-year cohort study conducted by researchers from Japan, comprising nearly 39,000 older adults found that people living in rental flats and owner-occupied detached houses face higher risks of cardiovascular death compared with those in owner-occupied flats. The study attributes to the increased risk to colder, less stable indoor temperatures in these housing types and suggests that improving housing quality to address these issues could lower cardiovascular mortality, particularly among men.
With the rapid spread of generative AI, the demand for more energy-efficient methods of powering the hardware is becoming apparent. Now, researchers have succeeded in applying on-axis magnetron sputtering on thulium iron garnet (TmIG)—a promising material that can enable high-speed, low-power information rewriting at room temperature—to build more energy-efficient magnetic random-access memory.
