Differences in individual quality and survival within species are a major focus in evolutionary ecology, but we know very little about the underlying physiological mechanisms that determine these differences. Telomere shortening associated with cellular senescence and ageing may be one such mechanism. To date, however, there is little evidence linking telomere length and survival. Here, we show...

To test whether lactation, another physiological state of low estrogen status, is associated with OA, a nationally representative dataset National Health and Nutrition Examination Survey (NHANES) 1999-...

Anchored telomeres get longer

T wo groups conclude that factors near telomeres alter the telomeres' nuclear positioning and thus their length. The lengths of telomeres, which are caps for chromosome ends, are kept consistent by a pathway that " counts " the number of Rap1 molecules bound to telomeres. This pathway signals through Tel1 to recruit the lengthening telomerase enzyme. Cells missing Tel1 have shorter but stable t...
