A study of over 12,000 people in the US compares Baby Boomer and Millennial financial outcomes. Millennials with typical middle-class life trajectories accumulated substantially more wealth than their Baby Boomer counterparts, while those with low-skilled service jobs or living with parents struggled financially.
A four-year blood-pressure intervention significantly reduced the risk of developing dementia among adults with high blood pressure, compared to those who received usual care. The study found that lowering systolic blood pressure to less than 130 mm Hg and diastolic blood pressure to less than 80 mm Hg reduced dementia risk.
A new risk calculator estimates a person's risk for cardiovascular disease (CVD) over the next 30 years by combining measures of cardiovascular, kidney, and metabolic health. The PREVENT risk calculator uniquely quantifies risks for CVD for each biological sex, without including race as a factor.
A population-based study found a significant increase in overdose-related OHCA from 2015 to 2021, with opioid-stimulant cases having lower survival rates. The combination of increasing incidence and lower survival rates supports prevention and treatment initiatives tailored to drug-specific profiles.
A new Northwestern University study estimates that approximately 171,000 premature deaths per year are linked to nitrogen dioxide (NO2) exposure, with a disproportionate number occurring in marginalized communities. The study found that NO2 pollution affects predominantly Black census tracts 47% higher than the national average.
Researchers at Johns Hopkins Medicine found that people with high body mass indexes (BMIs) do not pose a significant risk for postoperative complications following chest masculinization surgery. Despite this, BMI was still used to determine eligibility for the procedure in many cases.
Two new studies reveal that depression, anxiety and chronic stress increase the risk for heart and brain health complications. Researchers found that these mental health conditions can accelerate the development of cardiovascular disease risk factors.

A new analysis suggests that the US low-carbon transition is likely to create consistent job growth, particularly in the utilities and construction sectors. However, major fossil fuel-producing states may need to prepare for fewer mining jobs and plan carefully to ensure a 'just' transition for all workers.
A new study found that oral contraceptive pill users have a lower prevalence of major depression (4.6%) compared to former users (11.4%). The researchers suggest two possible explanations for the findings: removing concerns about unwanted pregnancy and survivor bias.
The study analyzed global data from the past three decades, revealing an overall increase in hypertensive heart disease (HHD) prevalence but a decrease in mortality and disability-adjusted life years (DALYs). The burden of HHD is particularly concerning for healthcare systems due to higher prevalence with lower mortality rates.
A new study finds that heat-related cardiovascular deaths may more than double in the US by the middle of the century, with elderly and Black adults being most at risk. The projections suggest that reducing greenhouse gas emissions can mitigate this impact, but infrastructure interventions such as increasing tree cover may also be effe...

The findings suggest whole families moved residence across Mesoamerica and integrated into new societies, challenging previous assumptions about foreign treatment.
A study published in PLOS ONE found correlations between climate change and human population trends in Central European regions. During warm periods, populations increased due to improved crops and economies, while during cold periods, populations decreased, leading to cultural shifts and potential social inequality.
A recent study published in The Journals of Gerontology – Series B found that having more children can produce economic, social, emotional, and biological burdens that impact health, especially chronic conditions and depression. In contrast, adults with fewer children were more likely to report poor self-rated health in certain countries.

Higher SHC participation rates are associated with lower ESKD incidence, suggesting the importance of regular health checkups at a population level.
A new study found that residents of neighborhoods with more greenspace tend to have longer telomeres, indicating better cellular health. However, the positive impact of greenspace is not enough to compensate for other environmental challenges like air pollution and racial segregation.
A new study finds that four out of five Miami-Dade County residents may face disruption or displacement due to sea-level rise, with lower-income people bearing the brunt. As habitable areas shrink and housing prices rise, only a small number of affluent residents can relocate, while many others are trapped in low-lying properties.
A new study reveals a reversal in the trend of early-onset lung cancer, now affecting younger women and middle-aged adults. The increased incidence in women is attributed to rising rates among those born in the 1960s, without higher smoking prevalence.

A recent study found that social factors are a stronger influence on water-quality violations than median household income. The study's social vulnerability index captured three times as much of the population affected by water-quality issues as median income did.
A new study by the Complexity Science Hub has pinpointed three main drivers of the Qing Dynasty's collapse: population explosion, elite competition, and financial burden. These factors culminated in a series of uprisings that led to the dynasty's downfall despite being wealthier than modern-day China.
A recent study published in Science suggests that an early ancestral bottleneck may have pushed modern humans to the brink of extinction. The research, conducted by scientists at the Chinese Academy of Sciences Headquarters, analyzed ancient DNA samples and found evidence of a significant population decline around 200,000 years ago.
A study by McGill University found that higher-income individuals and those with university education had increased rates of melanoma, while those earning less than $50,000 were more likely to work outdoors and experience occupational sun exposure. Men also had higher rates of melanoma and other skin cancers due to increased UV exposure.
A study led by Washington State University researcher found that half a million children lived in 'doubled-up' households with grandparents during the pandemic. These arrangements were mainly driven by economic and instrumental needs, such as childcare and elder care, outweighing health concerns.
