Life expectancy at birth differs by poverty level, with richer counties showing stronger increases.
A study published in PLOS ONE found that chronological age was the single best predictor of death in three countries, followed closely by self-reported mobility. Telomere length, previously believed to be a powerful biomarker for aging and mortality, ranked lower than other indicators in predicting mortality.
Researchers found that managers and subordinates adjust their behavior to match stereotypes, leading to misunderstandings. The study showed that people play down their competence to appear warmer and hide their warmth to appear more competent.

Researchers found that middle-aged white Americans have seen a sharp increase in death rates after 1998, primarily caused by drug and alcohol poisoning, chronic liver disease, and cirrhosis. This trend reverses decades of progress and is not seen in other rich countries or minority groups.
A new policy article suggests that opening up access to power grids, ending fossil-fuel subsidies, and supporting renewable energy technologies can make wind and solar power cheaper. The authors argue that modernizing power grids and ensuring policies related to renewable energy are crucial for reducing emissions.
Researchers used anonymous mobile phone records for 15 million people in Kenya to track the spread of rubella, predicting seasonal disease patterns. The study shows that cellphone movement can be a predictor of infectious-disease spread, particularly among children during school breaks.
A proposed global vaccine-development fund could help make vaccines available for emergency use, saving thousands of lives. The fund would cover the financial burden of vaccine development, addressing barriers such as high costs, limited market potential and lack of government support.
A report by Princeton researchers suggests that partnering with Iran's neighbors and E3+3 nations could reduce proliferation risks. The authors propose a multinational approach to uranium enrichment, giving access to the plant while ensuring transparency.
A new study proposes a two-by-two blind trial design that considers interactions between behavior and treatment. The researchers found that participants who felt confident about receiving treatment changed their behaviors in ways that improved health outcomes and made the drug more effective.
A new study reveals that measles can suppress the immune system for up to three years, making children highly vulnerable to other infectious diseases. The research, published in Science, provides epidemiologic evidence that measles attacks immune memory cells, leading to a state of 'immune amnesia'.
A new report finds that only a small percentage of Africa's wet savannas have potential to produce staple crops while emitting less carbon dioxide. Converting these lands into farmland would release significant greenhouse gases, threatening biodiversity and local food security.

The findings highlight the need for improved maternal nutrition monitoring in India, where social status and patriarchal societies contribute to health disparities.
A new report finds that sub-Saharan Africans perceive their own health care systems as low-rated, but prioritize jobs and economic growth over healthcare. The research suggests that HIV/AIDS aid may have improved perceptions of health care in some countries, despite chronic poverty and unemployment.
Researchers have confirmed the discovery of a new bird species, the Sulawesi streaked flycatcher, after 15 years. The bird has distinct plumage, body structure, song and genetics compared to other flycatchers, confirming its classification as a new species.

The researchers analyzed data from the Gallup World Poll and found that residents of these countries experience a U-shaped curve of increased satisfaction after middle age.
New research from Princeton University shows that recessions have a profound impact on fertility, leading to lower birth rates in the short and long term. Women who experience high unemployment during their 20s are more likely to remain childless by age 40, with the effects increasing exponentially over time.
A new review published in PNAS reveals that Americans view scientists as competent, but not entirely trusted. To gain public trust, scientists should focus on conveying warm intentions and expertise, rather than persuasive agendas. The study's findings highlight the importance of warmth and trustworthiness in scientific communication.
A new report by Princeton University researchers suggests that expanding the age of eligibility for measles vaccination from 12 to 15 months could significantly increase coverage in Africa. The study found that increasing the age range would have the most impact on countries with high rates of unvaccinated children.
Researchers found that a husband's declining health increases his wife's glucose levels, while a widowed spouse only affects men's blood sugar control. Caregiving demands on married women may lead to poor eating habits and inadequate glucose control.
Researchers argue that IPCC's approval process limits its credibility by not considering diverse policy views. By analyzing global emissions data, they show how different interpretations can be made from the same dataset, highlighting the need for a more connected scientific-policy interface.
Reducing agricultural production in provinces like Inner Mongolia, Heilongjiang, and Hebei, and importing food from other regions, could conserve China's water resources. A new report suggests that restructuring these regions could reduce national water use while maintaining food security.
