Future Clock
In an important step for the longevity field, scientists have found that epigenetic age acceleration, as measured by four popular methylation clocks, is correlated with aging and mortality in humans [1]. Lack of human data Studying aging obviously requires having reliable biomarkers of aging. Epigenetic clocks that utilize the correlation between aging and genome methylation...

Using a Berlin cohort, a study published in GeroScience has uncovered a link between Vitamin D supplementation and a reduction of epigenetic age. On the back of previous work This study's cohort consisted of 60- to 85-year-old participants in the Berlin Aging Study II (BASE-II). The researchers had previously used data from this cohort to...
Antique clock
Scientists have shown that only some of the hallmarks of aging affect methylation clocks that are used to measure biological age [1]. The big black box Epigenetic clocks that measure biological age based on aging-related changes in genome methylation have been a great success. They enable researchers to analyze the effects of various interventions on...
Chaotic clocks
A preprint published in bioRxiv has demonstrated that the second-generation aging clocks PhenoAge, DunedinPACE, and GrimAge show increased but reversible age acceleration in mice and people exposed to significant stress. What clocks are for Epigenetic Clocks - What are they?An epigenetic clock is a biochemical test that uses DNA methylation levels and accumulation of methyl...
Alzheimer's MRIs
The risk of Alzheimer’s disease goes up with age, and the number of people living with Alzheimer's is growing. While it is known to be associated with the loss of proteostasis, it has also been found to be associated with epigenetic alterations. An advanced online preprint in bioRxiv was published by Dr. Morgan E. Levine...

Publishing in Aging, a team of researchers has explained the relationship between tuberculosis (TB) and multiple aspects of aging, including epigenetic alterations and the senescence-associated secretory phenotype (SASP). A disease known to cause long-term harm Tuberculosis, a disease that has proliferated around the world, kills 1.4 million people every year. Previous research has shown that,...
