New formula predicts how people will migrate in coming decades

Scientists at Rockefeller University have developed a predictive model of worldwide population shifts that will provide more accurate estimates of migration patterns. The model accounts for approximately 60% of the variation in annual numbers of migrants and has the potential to improve resource allocation and economic conditions.

Ancient DNA evidence points to woolly mammoths' dynamic past

A new study analyzing ancient DNA from 160 mammoth samples across Holarctica suggests that North American mammoths replaced dwindling Siberian populations around 50,000 to 5,000 years ago. The findings refute the notion of climate change as a direct cause of extinction, instead pointing to a complex pattern of migration and evolution.

Malaria control goals are likely to be unachievable

Research finds that international malaria financing is insufficient to achieve the goal of halving the global burden of malaria by 2015. Funding commitments are largely tied to stable P. falciparum risk, leaving countries with high but low-risk populations poorly supported.

Opting out revolution a myth: Study shows steep employment gains for women, mothers

A study by Christine Percheski reveals that professional women's employment levels have made steep gains over time, especially for mothers of young children and women in historically male professions. The study shows a shrinking employment gap between mothers and childless women, with more women working full-time year-round.

US sees decline in number of general surgeons

The number of general surgeons per 100,000 Americans has declined by over 25% since 1981, mainly due to an aging population and a lack of rural training opportunities. Rural areas are disproportionately affected, with urban areas experiencing a slightly greater decline.

Lucky squirrels born with 'silver spoon' effect

A study of female red squirrels found that those born into favorable circumstances with abundant food, warmer spring weather, and lower population experienced increased reproductive success and longevity. In contrast, those born into harsher conditions struggled to reproduce and lived shorter lives.

A genetic study of Latin Americans sheds light on a troubled history

A recent molecular analysis of ancestry across Latin America has revealed a marked differentiation between regions, demonstrating a 'genetic continuity' between pre-and post Columbian populations. The research shows that mostly Native and African women and European men contributed genes to the subsequent generations.

Who benefits from antidepressants? US health inequities

A new study published in PLoS Medicine suggests that antidepressants only provide clinically significant benefits for a small group of severely depressed patients. However, even among these patients, the improvement is not very great, and depressed people can still improve without chemical treatments.

Genetic diversity of European Americans and disease gene mapping

Researchers provide first genetic dissection of European American population structure, identifying key genetic variants that can correct for population substructure in disease association studies. By using a panel of 300 markers, researchers can determine whether observed associations are genuine or false-positives.

Poor Americans in the United States suffer hidden burden of parasitic and other neglected diseases

Large numbers of poor Americans are suffering from parasitic infections like toxocariasis, cysticercosis, and toxoplasmosis. These neglected diseases disproportionately affect minority populations living in inner cities and poor rural areas, causing significant health issues such as lung disease, epilepsy, and congenital birth defects.
