Education shifts the timing of family planning but does not prevent or avoid family formation. Structural barriers persist, including workplaces penalizing mothers and traditional marriage practices.
Young people aged 16-25 are three times more likely to start drinking alcohol than non-alcohol alternatives, according to new research from the University of Sheffield. Despite concerns about a potential 'gateway' effect, no evidence was found that no/lows impact young people's alcohol consumption.
A new study from Florida Atlantic University challenges the narrative that rising temperatures will drive Americans away, finding that heat alone isn't driving large-scale out-migration. Instead, population shifts are shaped more by economic opportunity, housing affordability and local quality of life than climate conditions.
Researchers identified patient-reported symptoms associated with GLP-1s, including menstrual changes, fatigue, and temperature-related complaints, that may not be fully captured in clinical trials or drug labeling. Nearly 4% of Reddit users reported reproductive symptoms, and fatigue was the second most common complaint.

The research used meter readings and census data to reveal strong links between social characteristics and energy use, with higher-income areas and larger households consuming more energy.
A new study finds that ending birthright citizenship would have the largest relative growth of unauthorized births among Asians, while Latinos would comprise 93% of the U.S.-born population without legal status in 2050. The policy change could disenfranchise highly educated immigrants who contribute to the economy.
Global maternal deaths fell to 240,000 in 2023, but progress has slowed in recent years and remains uneven across countries. Improvements in access to quality care could substantially reduce mortality, particularly in high-burden regions.
