US mothers from 1965 to 2010: more TV, less housework

A study by the University of South Carolina's Arnold School of Public Health found that US mothers are less physically active than previous decades, spending more time watching TV than cooking, cleaning, and exercising. This decline in physical activity has led to a decrease in energy expenditure, potentially predisposing children to o...

Mice can inherit learned sensitivity to a smell

Scientists have discovered that mice can pass on learned sensitivity to a specific odor to their offspring via epigenetic alterations in the sperm or eggs. This phenomenon has significant implications for understanding psychiatric disorders and developing therapeutic strategies for intergenerational trauma effects.

ACP recommends tighter transfusion strategy to treat anemia in patients with heart disease

The American College of Physicians recommends restricting red blood cell transfusions to severe anemia cases in patients with heart disease. ACP also advises against using erythropoiesis-stimulating agents in mild to moderate anemia with heart conditions due to increased risks of thromboembolic events and stroke rates.

First Nations adults have more than double the risk of end-stage kidney disease

A study found that First Nations adults with diabetes are more than double the risk of developing end-stage kidney disease. The high rates of kidney disease among First Nations people are attributed to younger onset of diabetes, leading to increased survival time and likelihood of progression to end-stage renal disease.
