Chromosomal diversity in mole-rats of the genus Cryptomys (Rodentia: Bathyergidae) from the Zambezian region: with descriptions of new karyotypes
It is hypothesize that geomorphological changes and in particular river system dynamics in recent geological times have played an important role in the chromosomal diversification and may have provided opportunities for speciation to occur. Expand
Extended Longevity of Reproductives Appears to be Common in Fukomys Mole-Rats (Rodentia, Bathyergidae)
A 20-year breeding record of Giant mole-rats Fukomys mechowii, another social bathyergid species, found that breeders indeed lived significantly longer than helpers, irrespective of social rank or other potentially confounding factors. Expand
Living in a “stethoscope”: burrow-acoustics promote auditory specializations in subterranean rodents
It is suggested that hearing sensitivity has decreased during evolution of subterranean mammals to avoid over-stimulation of the ear in their natural environment. Expand
Sexual activity and reproduction delay ageing in a mammal
Here, it is shown that in a eusocial mammal, a nearly identical life history has evolved. Expand
Role of Intestinal Microbiota in Transformation of Bismuth and Other Metals and Metalloids into Volatile Methyl and Hydride Derivatives in Humans and Mice
The assumption that the Gut microbiota plays a dominant role for these transformation processes, as indicated by the production of volatile derivatives of various elements in feces samples, is supported by the observation that the gut segments of germfree mice are unable to transform administered bismuth to (CH3)3Bi.

Advanced glycation end-products as markers of aging and longevity in the long-lived Ansell's mole-rat (Fukomys anselli).
Markers of glycation and advanced glycation end-products formed in insoluble skin collagen of Ansell's mole-rat Fukomys anselli as a function of age and breeding status significantly increased with age after correction for breeder status and sex and pentosidine formation rate was lower than other short-lived rodents.

It is argued that the inclusion of naked mole-rats and bats in aging research was an important step forward, because it drew researchers' attention to certain oversimplifications of existing aging theories and to several features that appear to be universal components of enhanced longevity in mammals.

Long-lived rodents reveal signatures of positive selection in genes associated with lifespan
The results provide a meaningful resource for follow-up studies to mechanistically link identified genes and amino acids under positive selection to aging and lifespan determination, andemplary protein homology modeling suggests functional consequences for amino acid changes underpositive selection.

Comment on 'Naked mole-rat mortality rates defy Gompertzian laws by not increasing with age'
It is argued that this defiance of Gompertz's law ‘uniquely identifies the naked mole-rat as a non-aging mammal’ and that this conclusion is premature. Expand
