When immunity starts to harm. Inflammaging, CXCL9, and faster biological aging
When immunity starts to harm. Inflammaging, CXCL9, and faster biological aging

Inflammaging may be more than a consequence of aging. New data suggest that selected inflammatory proteins, including CXCL9, may be linked to faster epigenetic aging.

Daytime napping and mortality risk. When sleep may be a sign of an underlying health problem
Daytime napping and mortality risk. When sleep may be a sign of an underlying health problem

A nap does not always mean healthy recovery. In older adults, its duration, frequency, and timing may point to disrupted sleep, circadian misalignment, or underlying health problems.

The paradox of comfortable living - how convenience may accelerate aging
The paradox of comfortable living - how convenience may accelerate aging

A new study in king penguins suggests that a comfortable environment, constant access to food, and lower physical activity may accelerate epigenetic aging — even when total lifespan increases.

APOE4, meat and dementia risk. Why one diet may not work the same for everyone
APOE4, meat and dementia risk. Why one diet may not work the same for everyone

Diet does not act in isolation. APOE genotype may influence how the body responds to meat, fish and dietary patterns related to dementia risk.

Gut, vagus nerve, and memory. A new clue in brain aging research
Gut, vagus nerve, and memory. A new clue in brain aging research

A new study points to a possible mechanism linking gut bacteria, vagus nerve signaling, and memory decline during aging.

Positive attitude toward aging can really affect body and mind health
Positive attitude toward aging can really affect body and mind health

Positive age beliefs were associated with a higher chance of improvement in cognitive function and walking speed among older adults. This is an important signal for health, prevention, and the way society thinks about aging.

Not only street smog. Indoor air still shortens millions of lives
Not only street smog. Indoor air still shortens millions of lives

Air pollution does not end with street smog. For millions of people, one of the biggest health risks is created inside their own homes — during cooking and heating.

Humans reach their peak potential later than we think. A new look at intelligence, personality, and age
Humans reach their peak potential later than we think. A new look at intelligence, personality, and age

Although fluid intelligence declines relatively early, other traits — such as knowledge, emotional intelligence, moral reasoning, and resistance to some decision-making biases — may strengthen overall human potential with age.

Not only load matters. Exercise order may affect muscle fatigue
Not only load matters. Exercise order may affect muscle fatigue

Exercise order in resistance training may matter more than it often seems. A study in young men compared alternating and successive resistance training and found differences in muscle fatigue.
