A new meta-analysis in the British Journal of Sports Medicine found that higher physical activity decreases disease risk and early death. Researchers analyzed data from over 30 million people across 94 large studies. The study focused on non-occupational physical activity, including exercise and walking.
New Research Finds Link Between Salmonella And Climate Change
A new study in the Journal of Infection links salmonella outbreaks to climate change. Warmer temperatures, higher humidity, and lower rainfall increase infection risks.
Researchers examined 14 weather factors to estimate salmonella rates. They used case reports from 2000 to 2016 and weather data from England, Wales, and the Netherlands.
The study’s methods could apply to other countries. Salmonella cases likely follow similar weather patterns worldwide.
Pandemic Lockdowns Reduced Social Skills in Children: New Research
The COVID-19 pandemic redefined daily life for many families. Schools and daycares closed, parents worked from home, and social distancing limited interactions. These changes disrupted early childhood development. Until recently, researchers had not studied how they affected social cognition.
A new study in Scientific Reports compared two groups of 3.5- to 5.5-year-olds. Researchers tested one group before the pandemic, and the other afterward.
Researchers focused on false-belief understanding (FBU), a key social cognition skill. FBU is the ability to recognize others’ different or incorrect beliefs.
Results showed that children tested after the pandemic performed worse on false-belief tasks. Even after controlling for age and language skills, the post-pandemic group struggled more. The effect was stronger for children from lower-income families.
Malaria Research Now in Jeopardy as US Freezes Funding
The Trump administration’s foreign aid freeze halted major malaria vaccine research. The USAID Malaria Vaccine Development Program (MVDP) told partners to stop work immediately. The freeze disrupts collaboration between U.S. and international researchers.
Affected teams included experts from Johns Hopkins University and the University of Oxford. The program aimed to reduce child deaths by developing improved malaria vaccines.
The funding freeze also halted medicine shipments and raised global health concerns. Malaria kills about 450,000 children under five in Sub-Saharan Africa each year.
Measles Cases Surging as Vaccinations Plummet: What You Should Know
A measles outbreak in West Texas has grown to 58 cases. In eastern New Mexico, eight people have also tested positive.
Measles spreads easily and can cause serious complications. Young children are especially at risk.
Officials say the actual number of infections is likely higher. They estimate between 200 and 300 cases have gone untested. Knowing the signs of measles can help limit its spread.
