NewsAncestral mitoviruses discovered in mycorrhizal fungi
A new group of mitochondrial viruses confined to the arbuscular mycorrhizal fungi Glomeromycotina may represent an ancestral lineage of mitoviruses.

NewsProchlorococcus ancestors rafted out to sea on chitin particles
Scientists propose that ancestors of Prochlorococcus hitched a ride on passing exoskeleton particles, using the particles as rafts to venture further out to sea. These chitin rafts may have also provided essential nutrients, fueling and sustaining the microbes along their journey.

NewsBacteria evolve antibiotic resistance quickly by rejigging pumps
Bacteria can rapidly evolve resistance to antibiotics by adapting special pumps to flush them out of their cells, according to new research from the Quadram Institute and University of East Anglia.

NewsAfrican rhinos have retroviruses not found in their cousins
New research reveals that the genomes of African rhinos contain dozens of gammaretroviruses that are absent from the genomes of Asian rhino species, such as the Sumatran and Javan rhino, and the African black rhino has two related groups, one missing from the white rhinos.

NewsYeast evolves into multicellular life in the lab
A fascinating long-term evolution experiment has seen model organism ’snowflake yeast’ adapt into multicellular individuals more than 20,000 times larger than their ancestor.

NewsCyanobacteria membrane proteins similar to animals’
A dynamin-like protein, namely SynDLP, has been identified in the genome of a cyanobacterium.

NewsAlgae yield clues to how complex life developed
Researchers studying green algae in Swedish lakes have succeeded in identifying which environmental conditions promote multicellularity.

NewsExpedition to search out invisible life in Galápagos
An international research team led by the Netherlands Institute of Ecology (NIOO-KNAW) is to search for invisible life in the Galápagos Islands. The Galápagos Microbiome Project - a group of scientists from the Netherlands, Ecuador, Spain and Brazil - intends to probe the uniqueness and diversity of microbial life on ...

NewsMicrobes bingeing on burned soil could return land to life after wildfires
Researchers have identified bacteria and fungi that not only survive but thrive during the first year after a wildfire, findings that could help bring land back to life after fires that are increasing in both size and severity. The Holy Fire burned more than 23,000 acres ...

NewsE coli strain may have evolved too far to be fit for lab purposes
A model organism used in laboratories for the past 100 years has evolved so extensively that it may no longer be fit for purpose, according to a new study.

NewsFlagellate study reveals how cells gain control over their bacterial symbionts
A research team has cast fresh light on how eukaryotic cells integated bacteria in the course of evolution to become organelles, thanks to a study of the single-celled flagellate Angomonas deanei, which contains a bacterium that was taken up relatively recently.

NewsDiscovery of world’s oldest DNA breaks record by one million years
Microscopic fragments of environmental DNA dating back two million years has been found in Ice Age sediment in northern Greenland, opening a game-changing new chapter in the history of evolution.
