Autotrophic Biofilms Sustained By Deeply-sourced Groundwater Host Diverse CPR Bacteria Implicated In Sulfur And Hydrogen Metabolism
Candidate Phyla Radiation (CPR) bacteria are commonly detected yet enigmatic members of diverse microbial communities.
Astrobiologists Expand Knowledge Of Virus Diversity
Astrobiologists supported by NASA have completed a study of RNA viruses on Earth and have vastly expanded knowledge of virus diversity. Currently, there are thought to be five broad categories […]
Away Team Mission On Earth: Mapping Fungal Networks On Earth’s Most Remote Island
In the middle of the Pacific Ocean is an uninhabited atoll that houses underground mycorrhizal networks that may have evolved a unique ability to cycle nutrients between seabirds, rainforest trees, […]
Early Selection Of The Amino Acid Alphabet Was Adaptively Shaped By Biophysical Constraints Of Foldability
Whereas modern proteins rely on a quasi-universal repertoire of 20 canonical amino acids (AAs), numerous lines of evidence suggest that ancient proteins relied on a limited alphabet of 10 ‘early’ […]
A New Branch On The Tree Of Life
There’s a new branch on the tree of life and it’s made up of predators that nibble their prey to death.
An Update On Eukaryotic Viruses Revived From Ancient Permafrost
One quarter of the Northern hemisphere is underlain by permanently frozen ground, referred to as permafrost.
An Atacama Desert Microbial Community As A Model For Astrobiology
The grit crust is a recently discovered, novel type of biocrust made of prokaryotic cyanobacteria, eukaryotic green algae, fungi, lichens and other microbes that grow around and within granitoid stone […]
New Information On The abilities Of Tardigrades
Tardigrades are tiny (0.5-1 mm) eight-legged animals famous for being among the toughest organisms on the planet.
Earth’s Oldest Stromatolites And The Search For Life On Mars
The earliest morphological traces of life on Earth are often highly controversial, both because non-biological processes can produce relatively similar structures and because such fossils have often been subjected to […]
