    en.wikipedia.org/wiki/Biomarkers_of_aging

    Levels of CD4 and CD8 memory T cells and naive T cells have been used to give good predictions of the expected lifespan of middle-aged mice. [5] Advances in big data analysis allowed for the new types of "aging clocks" to be developed. The epigenetic clock is a promising biomarker of aging and can accurately predict human chronological age. [6]

    The programs comprising Skin Biology and Diseases support a broad portfolio of basic, translational, and clinical research in skin. These efforts include work on the developmental and molecular biology of skin and skin appendages (such as the hair follicle), the study of skin as an immune organ, and the genetics of skin diseases.

    en.wikipedia.org/wiki/Argon–argon_dating

    Argon–argon (or 40 Ar/ 39 Ar) dating is a radiometric dating method invented to supersede potassium–argon (K/Ar) dating in accuracy. The older method required splitting samples into two for separate potassium and argon measurements, while the newer method requires only one rock fragment or mineral grain and uses a single measurement of argon isotopes.

    Biogerontology is the sub-field of gerontology concerned with the biological aging process, its evolutionary origins, and potential means to intervene in the process. [1] The term "biogerontology" was coined by S. Rattan, and came in regular use with the start of the journal Biogerontology in 2000. It involves interdisciplinary research on the ...

    The NCI-60 cancer cell line panel is a group of 60 human cancer cell lines used by the National Cancer Institute (NCI) for the screening of compounds to detect potential anticancer activity. [ 1 ] Purpose

  7. Epigenetic clock - Wikipedia

    en.wikipedia.org/wiki/Epigenetic_clock

    An epigenetic clock is a biochemical test that can be used to measure age. The test is based on modifications that change over time and regulate how genes are expressed. Typically, the test examines DNA methylation levels, measuring the accumulation of methyl groups to one's DNA molecules, or more recently, based on the histone

    Accelerated aging was further refined during the 1920s, with tests using sunlight and elevated temperatures being used to rank the permanence of various papers in the United States and Sweden. In 1929, a frequently used method in which 72 hours at 100 degrees Celsius is considered equivalent to 18–25 years of natural aging was established by ...
