Pagan-Christian trade networks supplied horses from overseas for the last horse sacrifices in Europe

Research from Cardiff University reveals that horses were sourced from Scandinavia using extensive trade networks, contrary to previous theories that stallions were locally-sourced. Genetic analysis shows that one in three sacrificed horses were mares, suggesting prestige played a key role in their selection.

A long-term ketogenic diet accumulates aged cells in normal tissues, a UT Health San Antonio-led study shows

A new study led by UT Health San Antonio found that long-term ketogenic diets can induce senescence, or aged cells, in normal tissues, affecting heart and kidney function. However, an intermittent ketogenic diet regimen eliminated these pro-inflammatory effects.

Aerobic exercise performed in the evening benefits elderly hypertensives more than morning exercise

A study of 23 elderly patients with hypertension found that evening aerobic exercise improved baroreflex sensitivity, a mechanism that regulates blood pressure. This improvement led to better blood pressure regulation and reduced muscle sympathetic nerve activity, making evening exercise more effective than morning exercise.
