In this project led by James Munday, we quantified the post-sampling degradation of viral RNA in wastewater. Taking into account this degradation is core towards unbiased quantification of epidemiological dynamics based on wastewater data.

Post-sampling degradation of viral RNA in wastewater impacts the quality of PCR-based concentration estimates Successful wastewater-based infectious disease surveillance programs depend on regular, reliable molecular detection of nucleic acids in municipal wastewater systems. This process is challenged by the...

📢Today Pathoplexus announces the inclusion of 2 new viral pathogens: RSV (A & B) and HMPV.

These respiratory viruses cause a serious health burden, particularly in infants & the vulnerable, & Pathoplexus aims to support sequence sharing to improve understanding & response.

"A mathematical theory of evolution": phylogenetic models dating back 100 years | Philosophical Transactions of the Royal Society B: Biological Sciences Can't sign in? Forgot your password?

So many great scientists contributed papers to the special issue! To get an overview over the history and state of phylogenetic models and the papers of the issue, you might want to start reading the introduction to the issue doi.org/10.1098/rstb... and then dive into the variety of exciting papers!

I first read the famous 1925 Yule paper at its 80th birthday - during my Master thesis work, and it shaped my research profoundly. It was a pleasure and honour to lead this special 100 anniversary issue celebrating Yule's legacy and phylogenetic models with @noahrosenberg.bsky.social and Mike Steel!
