A recent study published in Cancer Epidemiology, Biomarkers & Prevention found that men were more likely to be diagnosed with regional and distant stages of 20 nonreproductive solid cancer types in the United States. Men were significantly more likely than women to be diagnosed with regional tongue cancer, salivary gland cancer, oropha...
A population-based study found no association between prenatal paracetamol exposure and risk of autism spectrum disorder or attention-deficit/hyperactivity disorder in offspring. The study suggests that positive signals from previous research may be due to familial confounding.
Rates of new obesity cases rose by 4% between 2019 and 2025, with the largest increases seen among young adults. The study also found significant disparities in obesity rates across sociodemographic groups and geographical regions, highlighting the need for deep-seated change to address the underlying factors driving obesity.

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.

The research shows that pesticide exposure increases the risk of cancer by 150% in areas with high levels of pollution, and highlights early biological effects before cancer develops.
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.
A Concordia University study found that demographic factors such as income and household size drive energy consumption in Quebec's major urban centres. 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.
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.

A population-based cohort study found that U.S.-born individuals had significantly higher odds of infant mortality, particularly among full-term births. Sudden unexpected infant death was a major contributor to these disparities, highlighting the need for investigation into underlying factors contributing to these disparities.
Researchers found that male fish exposed to vitamin C and potassium perchlorate showed improved fertility and less damage to their testes compared to those exposed only to the chemical. The study suggests a potential safeguard for individuals regularly exposed to these chemicals, including military personnel.
Research from the University of St Andrews found that increases in women's parliamentary representation are related to enhanced public trust in national parliament. The study, which analyzed data from 107 countries, suggests that broad representation within parliament drives trust-building effects.
A population-based cohort study found that virtual sick visits to primary care were associated with a small increase in emergency department use in children aged 3 months or older. The study suggests judicious use of virtual primary care to manage acute illness in children is warranted.
A new study reveals that reducing mortality through large-scale investment in public health is a more effective and ethically sound strategy than encouraging people to have more children. By focusing on lowering mortality rates, countries can slow population decline and maximize the return on investment in their existing population.
New York state's K-12 enrollment declined by more than 250,000 students over the past decade, while charter schools saw a nearly tripled enrollment and homeschooling rates doubled. The decline is largely attributed to an aging population and shifting educational trends.
A new study led by UniSC has pinpointed areas and times when large seabirds like the Antipodean albatross are most at risk of injury or death from fishing longlines. The researchers identified winter hotspots in a latitudinal band near the Tropic of Capricorn, where juvenile and female birds face the highest risk.
A new study found a significant rise in ADHD stimulant prescriptions in Ontario, with a 157% increase from 2015 to 2023. The study calls for better clinical guidance to ensure medications are prescribed appropriately and prevent adverse health effects.
A repeated cross-sectional study found a significant increase in stimulant prescribing for ADHD, with the largest acceleration observed among female adolescents and young adults aged 18 to 64. The study's findings are consistent with prior research but provide new insights into population-level trends.
Research from Florida Atlantic University strengthens evidence that alcohol consumption increases cancer risk, particularly for breast, colorectal, and liver cancers. Higher intake and specific groups, such as African Americans and those with obesity or diabetes, are found to be more vulnerable to the risks.
A recent study found that over 70% of pregnant women consume alcohol-free or low-alcohol drinks, primarily for safety reasons. However, many feel there is a need for clearer information and support on the suitability of these alternatives during pregnancy and breastfeeding.
A Rutgers-led study reveals that exposure to housing hardship before age 5 may influence housing insecurity in early adulthood. Adults who experienced childhood housing insecurity showed similar probabilities of housing insecurity at age 22, even after their housing situation stabilized.
The world's online population grew to 6 billion, while 2.2 billion remain offline, highlighting the importance of digital infrastructure, affordable services, and skills training to achieve universal connectivity. Deep digital divides persist, with uneven coverage, affordability, and skill levels across high- and low-income countries.
Researchers developed a 'humanized' model of aortic valve calcification, enabling testing of potential treatments. The breakthrough could lead to new therapies to stop or reverse calcium buildup, improving outcomes for people with heart disease.
