The study's findings have significant implications for eradicating malaria in parts of Africa, Asia, and Latin America.
A new survey reveals that older Americans are working longer, with 82% of those age 50+ likely to continue working in retirement. The Great Recession has led to a shift in retirement plans, with many now planning to retire later than expected and favoring solutions to ensure Social Security's long-term health.
A Baylor University study found that older consumers purchase hybrid cars for social values, pride, and prestige, rather than environmental concerns. This knowledge can help marketers, as senior citizens are willing to pay extra for eco-friendly products.

The research used data from a nationally representative sample of US adults and followed them over a six-year period to confirm deaths.
A recent genetic study has uncovered a significant demographic shift in India's population, occurring approximately 1,900-4,200 years ago. This mixture of ancestral populations has left its mark on nearly every group in India, influencing the present-day caste system and increasing the incidence of genetic diseases.
A new study published in American Journal of Human Genetics suggests that modern-day India is the result of recent population mixture among divergent demographic groups. The findings provide evidence for a genetic mixture of two ancestral groups: Ancestral North Indians and Ancestral South Indians, which occurred around 1,900 to 4,200 ...

Researchers found that cities with higher social-tie density experience increased productivity due to face-to-face interactions. This concept was previously attributed to 'superlinear scaling', but the new study provides a more nuanced explanation. Cities with poor transportation infrastructure and megacities may not benefit from this ...
A recent analysis found that the rise in treated disease prevalence and spending per treated case accounted for most of the increase in US healthcare spending between 1987 and 2009. The study, published in Health Affairs, also revealed that obesity contributed to 10.4% of the overall rise in spending.
Mexican-American adults born in the US are more likely to report physical limitations compared to immigrant counterparts. This disparity is attributed to various factors including acculturation levels and lifestyle changes over time.
Research finds that low birth weight contributes to approximately 10-15% of later intellectual disability cases. Medical interventions, such as intensive care technologies, may increase ID prevalence, contrary to previous therapies like newborn screening.
Researchers found targeted screening for hepatitis C to be cost-effective in populations with a higher estimated prevalence rate. The study showed that screening followed by guideline-based treatment can save $47,000 per quality-adjusted life year.
A new study found that Google searches for information on all major mental illnesses followed seasonal patterns, with winter queries consistently higher than summer ones. This suggests that mental illness may be more strongly linked to seasonal patterns than previously thought.
A new study reveals that Canada is the country least capable of effectively managing its drug pricing regime due to its unique universal healthcare system. The researchers suggest three principles - pragmatism, discipline, and transparency - for developing an effective pricing strategy.
Reducing food waste is vital to feed a global population of 9 billion by 2050. Scientists estimate that up to half of the food harvested from farmers' fields in developing countries is lost due to spoilage and pests. In developed countries, households throw away about 4 out of every 10 pounds of food produced each year.
A new study by Dr. Christine Milrod and Dr. Martin A. Monto found that only about 14% of men have ever paid for sex, and those who do are not particularly different from the general population. The researchers also discovered that arrested customers are more likely to be married, working full-time, and sexually liberal than non-customers.
Weill Cornell researchers argue that ACOs may not be improving population health as intended, as their focus is often solely on medical care for patients within their geographic area. The authors emphasize the importance of clearly defining population health to formulate effective healthcare and social service policies.
