Nels and Vincent discuss how the rewetting of seasonally dried soils, a critical event in Mediterranean grasslands that reactivates dormant soil microorganisms, leading to pulses of carbon and nitrogen mineralization, and is accompanied by a bloom of viral diversity, followed by extensive viral community turnover.
Nels and Vincent take apart an amazing symbiosis consisting of two bacteria, one bacteriophage, and seven different genomes all within a single-celled alga.
Nels and Vincent review a collision of synthetic biology and experimental evolution, using a minimal synthetic bacterial cell with only 473 genes, the smallest genome of any known organism that can be grown in lab culture.
Nels and Vincent explain a study of how interspecies competition between two algae influences evolution of metabolism and size.
Nels and Vincent discuss new findings using phylogenetic approaches about how complex eukaryotic cells emerged from prokaryotic ancestors, which firmly place eukaryotes as a clade nested within the Asgard archaea.
Nels and Vincent provide insights into the mystery of mouse mummies on the summits of >6000 m Andean volcanoes, including whether they were living there and if so why?
Nels and Vincent discuss the observation that cells on a boundary of a solid tumor have higher growth rates compared to those in the center and how to model this difference using genome sequencing data.
Nels and Vincent review a study of the dogs of Chernobyl which reveals that genetically distinct populations with different amounts of western breed contributions to their genomes, the first step in assessing the effects of exposure to long-term ionizing radiation.
Nathan joins Nels and Vincent to discuss his approach to understanding how species adopt novel traits to overcome challenges, and its application to identifying coding and noncoding sequence changes that underlie mammalian hairlessness. Hosts: Nels…
Nels and Vincent discuss how evolution of changes in stop codon assignment might occur, and a novel mechanism for altering the meaning of translation stop codons discovered in a trypanosomatid with the apropos name, Blastocrithidia nonstop.
