  2. Aging in dogs - Wikipedia

    en.wikipedia.org/wiki/Aging_in_dogs

    The other common system defines "dog years" to be the actual calendar years (365 days each) of a dog's life, and "human years" to be the equivalent age of a human being. [2] By this terminology, the age of a 6-year-old dog is described as 6 dog years or 40–50 human years, a reversal from the previous definition.

  3. Relationship between telomeres and longevity - Wikipedia

    Telomeres at the end of a chromosome. The relationship between telomeres and longevity and changing the length of telomeres is one of the new fields of research on increasing human lifespan and even human immortality. [1] [2] Telomeres are sequences at the ends of chromosomes that shorten with each cell division and determine the lifespan of ...

    A theoretical study also suggested that the maximum human life expectancy at birth is limited by the human life characteristic value δ, which is around 104 years. [ 17 ] In 2017, the United Nations conducted a Bayesian sensitivity analysis of global population burden based on life expectancy projection at birth in future decades.

    For this study, the researchers sequenced the DNA of two dogs, Kedves, a 22-year-old female, and, Buksi, a 27-year-old male.

    Say you have a 4-year-old Labrador named Comet — with the new equation, Comet's real "dog age" would be slightly older than 53. The reason for the difference is actually pretty simple.

  8. Telomere - Wikipedia

    en.wikipedia.org/wiki/Telomere

    Telomere length varies greatly between species, from approximately 300 base pairs in yeast [24] to many kilobases in humans, and usually is composed of arrays of guanine-rich, six- to eight-base-pair-long repeats. Eukaryotic telomeres normally terminate with 3′ single-stranded-DNA overhang ranging from 75 to 300 bases, which is essential for ...

  9. Biological immortality - Wikipedia

    en.wikipedia.org/wiki/Biological_immortality

    In a four-year study, 3 cohorts of hydra did not show an increase in mortality with age. It is possible that these animals live much longer, considering that they reach maturity in 5 to 10 days. [16] However, this does not explain how hydras are subsequently able to maintain telomere lengths. [citation needed]
