Ancient clock
An accepted manuscript in the Journals of Gerontology has described how a third-generation epigenetic clock is a predictorΒ  of future frailty. Are epigenetic and physiological metrics connected? This paper begins with an examination of two different methods of measuring aging processes. The first is the well-known epigenetic clocks, and this paper lists several, including the...
Clockworks
Assisted by TruDiagnostic, a team of researchers has published a preprint paper in which -omics data has been used to create an epigenetic methylation clock. Why -omics? Epigenetic Clocks - What are they?An epigenetic clock is a biochemical test that uses DNA methylation levels and accumulation of methyl groups on DNA to determine biological age....
Foreground Clock
Publishing in Aging, the Conboy research lab has outlined the problems with existing machine learning-based clocks and created a new clock based on epigenetic noise. The problem with linear regression This paper begins with a description of the elastic net, an artificial intelligence algorithm that powers the majority of biological clocks, including the Horvath biological...
Full Biomarkers
The Biomarkers of Aging Consortium, an initiative uniting about 200 geroscientists around the goal to inform and guide the use of biomarkers of aging, has put out its first paper [1]. The need for biomarkers Since studies with lifespan as their endpoint can take a prohibitively long time, especially in humans, the importance of reliable...
Advanced Clock
In a paper published in Geroscience, researchers have developed a metric of systemic inflammation and used it to estimate mortality, finding that it performs better than epigenetic clocks. Evaluating a danger What is Inflammaging? Chronic Inflammation and AgingOne of the aging processes consists of a chronic, smoldering background of inflammation that researchers call β€œinflammaging”.Read More...
Variety of clocks
A group of researchers led by Morgan Levine of Altos Labs has created a set of methylation clocks that can detect various aging patterns [1]. The less-than-perfect revolution The discovery that genome methylation patterns correlate with various processes of aging led to the development of methylation (epigenetic) clocks. They first appeared more than a decade...
