Genome maintenance by telomerase is a fundamental process in nearly all eukaryotes. But where does it come from?

Today, we report the discovery of telomerase homologs in a family of antiviral reverse transcriptases, revealing an unexpected evolutionary origin in bacteria.

Genomic constraints shape the evolution of alternative routes to drug resistance in prokaryotes Background Variation within the prokaryotic pangenome is not random, and natural selection that favours particular combinations of genes appears to dominate over random drift. What is less clear is wh...

New preprint reveals bacteria can't just collect all resistance genes like Pokemon cards.
We found mutually exclusive evolutionary pathways to multidrug resistance in E. coli & P. aeruginosa - some resistance mechanisms actively prevent others from coexisting www.biorxiv.org/content/10.1...

Using herbarium collections to study genetic responses to global change Earth's c. 406 million herbarium specimens represent a largely untapped resource of genetic data that could transform our understanding of global plant populations. Advances in DNA sequencing have ma...

Dating the evolution of oxygenic photosynthesis using La-Ce geochronology - Nature 138La-138Ce geochronology shows that La/Ce fractionation, and Ce oxidation, occurred at the time of deposition, placing the origin of oxygenic photosynthesis in the Mesoarchaean or earlier.

Cyanobacterial Argonautes and Cas4 family nucleases cooperate to interfere with invading DNA Bobadilla Ugarte et al. have functionally, structurally, and biochemically characterized cyanobacterial APACE1 immune systems. In APACE1 systems, a pAgo protein mediates small DNA-guided DNA interference, whereas ACE1 contributes to guide DNA processing. This study broadens our mechanistic understanding of how diversified pAgo systems protect their bacterial hosts against invading DNA.

Major European institutes join race to save US science data As the administration of US President Donald Trump slashes budgets, crucial climate and other data sets could disappear.

Several research institutes in Germany are joining a worldwide grassroots effort to save science data sets that researchers fear could be deleted by US President Donald Trump’s administration, Nature has learnt.

Given the discussion today. #EthicalPublishing is possible.

Our ethos for many years now:

1. All papers preprinted along with data.
2. No commercial publishers.
3. Only publish in scientific society journals and with reputable non-profit publishers.
4. Collaborators do what they want.

Illustration depicting the ways in which fungi can exchange genetic material with each other. Starship mediated HGT is confirmed experimentally in this preprint.

We did it! We caught Starship #transposons moving between #fungal species in the lab, including between species separated by ~100my. We think Starships are a mediator of HGT in fungi, akin to conjugative elements in bacteria. Check out the preprint. www.biorxiv.org/content/10.1...

Telomeric transposons are pervasive in linear bacterial genomes Eukaryotes have linear DNA and their telomeres are hotspots for transposons, which in some cases took over telomere maintenance. Here we identify several families of independently evolved telomeric tr...

Most conservation funds go to large vertebrates at expense of ‘neglected’ species Study shows funding bias towards animals like rhino while other endangered species including amphibians and algae disregarded

Conservation funding “82.9% was assigned to vertebrates. … while fungi and algae were barely represented at less than 0.2%”
