Life expectancy increased as world addressed major killers including diarrhea, lower respiratory infections, and stroke

The study found that reductions in deaths from chronic respiratory diseases, stroke, lower respiratory infections, and cancer led to the largest net gain in life expectancy between 1990 and 2021. The super-region of Southeast Asia, East Asia, and Oceania had the largest net gain, while South Asia had the second-largest increase primari...

Demand for critical minerals puts African Great Apes at risk

A recent study reveals that the demand for critical minerals in Africa is putting African Great Apes at risk due to deforestation and habitat destruction. The study estimates that more than 180,000 gorillas, bonobos, and chimpanzees are at risk, with West African countries like Guinea being the most severely affected.

Genetic analysis reveals true origin of chronic kidney disease in undiagnosed patients

Researchers discovered that known genetic variants account for a large portion of chronic kidney diseases with unknown origin. The study found that 10% of patients had pathogenic variants in CKD-causing genes, and some hereditary renal diseases could be diagnosed and treated early on to slow down disease progression.

Relative deficiency in immune cells can account for poorer vaccination responses in the older population

A study found that older adults have weaker T cell responses to COVID-19 mRNA vaccinations, resulting in poorer antibody responses and SARS-CoV-2 immune protection. The study suggests a relative deficiency in interferon-gamma-secreting CD4+ T cells may explain this response.

Out of the park: New research tallies total carbon impact of tourism at Yellowstone

Researchers estimated that recreation visits to Yellowstone produce over one megaton of carbon emissions per year, with an average of 479 kilograms attributable to each visitor. Despite this, the park's ecosystems still pull in around 1.5 megatons of carbon from the atmosphere each year.

Paper: Policy reforms urgently needed to mitigate racial disparities in perinatal mental health conditions

Researchers propose seven comprehensive changes to healthcare and economic policies to mitigate the burden of undiagnosed and untreated perinatal mental health challenges. These recommendations include training programs, payment models, paid family leave, and access to reproductive justice services.
