In this special collection, Aging seeks to bring together cutting-edge research that spans the cellular and molecular underpinnings of cognitive aging with insights into the psychosocial, behavioral, and environmental factors that modulate its course.
Aging (Aging-US) Research
A new study published recently as the cover of Aging Volume 17, Issue 6, describes a new method to estimate how fast the brain is aging. By analyzing lipids, or fat molecules, in brain tissue, researchers from the National University of Singapore and Hanze University of Applied Sciences created a biological “clock” called DoliClock.
This study introduces DoliClock, a lipid-based biological aging clock designed to predict the age of the prefrontal cortex using post-mortem lipidomic data. Significant age acceleration was observed in autism, schizophrenia, and Down syndrome.
Recent discoveries in aging research reveal a powerful insight: the biological changes that lead to chronic diseases begin far earlier than most people realize—often in midlife, well before symptoms appear. This early phase offers a valuable opportunity for prevention.
As we age, our brains become more sensitive to stress and disease. A recent study sheds light on a lesser-known risk: reduced oxygen levels.

Chronic mild hypoxia (CMH; 8% O2) triggers transient blood-brain barrier (BBB) disruption, an effect greatly increased with age. As BBB disruption predisposes to neuronal death and cognitive decline, here we defined the hypoxic thresholds that trigger BBB breakdown in young and aged mice, and then defined the age at which hypoxia-induced BBB disruption significantly increases.
