Mobile DNA - A new subpopulation of polar bears (Ursus maritimus) was recently discovered in the South-East of Greenland. This isolated colony inhabits a warmer climate zone, akin to the predicted...

Reduced insulin/IGF-1 signalling (IIS) robustly extends lifespan and enhances somatic stress resistance across taxa, yet its consequences for germline genome integrity remain unclear. Here we combine ...

Scientific Reports - Gum Arabic modulates the microbiota-gut-brain axis and affects general fitness in zebrafish

A hormone-free male birth control pill is undergoing clinical testing for the first time ever.

Background Alterations in the composition and function of the intestinal microbiota have been observed in organismal aging across a broad spectrum of animal phyla. Recent findings, which have been der...

Heredity - Environmentally induced variation in sperm sRNAs is linked to gene expression and transposable elements in zebrafish offspring

Based on a systematic analysis of environmental exposures associated with aging and mortality in the UK Biobank, the relative contributions of such exposures and genetic risk for mortality and a range of age-related diseases were compared, highlighting the potential beneficial effects of environment-focused interventions.

Proceedings of the National Academy of Sciences (PNAS), a peer reviewed journal of the National Academy of Sciences (NAS) - an authoritative source of high-impact, original research that broadly spans...

Abstract. Selection often favors different trait values in males and females, leading to genetic conflicts between the sexes when traits have a shared gene

Mapping transcription start sites across five mammalian species before, during, and after embryonic genome activation unveils widespread transposable element-driven transcription and co-option of evol...

One of the key processes that forms the basis of fertilisation is the tight interaction between sperm and egg. Both sperm and egg proteomes are known to evolve and diverge rapidly even between closel...

Nature - A spatially resolved single-cell transcriptomics map of the mouse brain at different ages reveals signatures of ageing, rejuvenation and disease, including ageing effects associated with T...

Species coexistence is shaped by a range of biotic and abiotic factors. Beyond predation, parasitism, and competition, one species may interfere with another's reproduction to induce sexual exclusion ...

Age and sex have been found to be important determinants of the mutation rate per generation in mammals, but the mechanisms underlying these factors are still unclear. One approach to distinguishing b...
