Delighted to see our work picked up by @theguardian.com this is a real window of opportunity for us to reduce carbon emissions to give the bears a hope at survival before it really is too late.

Lifespan-extending downregulation of insulin signalling reduces germline mutation load 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 ...

Do changes to insulin/IGF-1 signalling (IIS) that extend lifespan also protect the germline, or do they come with a mutational cost?

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

🧬 Our latest paper out in Scientific Reports!
We explored how Gum Arabic (a dietary fibre) affects the microbiota–gut–brain axis and whole-organism fitness in zebrafish.

What we found ⬇️

This is a simple parsimonious model to explain the evolution of lifespan extension by dietary restriction and other forms of stress that suppress fertility.

Happy to be part of this exciting study!

Integrating the environmental and genetic architectures of aging and mortality - Nature Medicine 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.

A study in Nature Medicine provides a comprehensive map of the contributions of environment and genetics to mortality and incidence of common age-related diseases, suggesting that the exposome shapes distinct patterns of disease and mortality risk. #Medsky 🧪

Try our new in silico PCR (sPCR) tool sharkmer- github.com/caseywdunn/s.... You give it primers and fastq reads, it gives you sequences that would be amplified by PCR. Works in minutes on a laptop for high copy regions like rRNA, great for species id etc. Feedback welcome. #bioinformatics #ngs
