Researchers have developed an epigenetic clock, "Retro-Age," that predicts biological age by analyzing DNA markers from ancient viral remnants in the human genome. This study highlights how the reactivation of these retroelements, such as HERVs and LINEs, impacts aging, inflammation, and genomic stability. The findings suggest that monitoring these markers could guide anti-aging therapies and improve health outcomes, particularly in conditions like HIV. The research also opens avenues for exploring treatments that may reverse the biological effects of aging.

A new study links diets rich in vitamins and minerals, with low added sugar, to younger biological age. Researchers found that healthier diets correlated with a younger epigenetic clock, even accounting for each gram of added sugar. The study is one of the first to show this link in a diverse group of midlife women. Findings highlight the importance of reducing sugar intake for better health and longevity.

A new study reveals that an eight-week vegan diet can reduce biological age estimations based on DNA methylation levels. The study, involving 21 pairs of adult identical twins, found that participants on a vegan diet showed decreases in biological age and the ages of their heart, hormone, liver, inflammatory, and metabolic systems.

Losing a close family member can accelerate biological aging, according to a new study. Researchers found that people who experienced the loss of a parent, partner, sibling, or child showed signs of older biological age. This effect was measured using DNA markers known as epigenetic clocks. The study underscores the long-term health impacts of grief and loss across the lifespan.

A new study reveals that the epigenetic state of neurons determines their role in memory formation. Neurons with open chromatin states are more likely to be recruited into memory traces, showing higher electrical activity during learning. Researchers demonstrated that manipulating these epigenetic states in mice can enhance or impair learning. This discovery shifts the focus from synaptic plasticity to nuclear processes, offering potential new avenues for treating cognitive disorders.
