metagenomics

Metagenomic sequencing can help detect unknown pathogens, but its widespread use faces challenges.

Researchers find so-called integrons, previously known only in bacteria, in their distantly related microbial relatives. 

Environmental DNA and climate change data suggest that vegetation scarcity led to the mass extinction of herbivore species, including Arctic mammoths.

Scientists in Canada trace how aquatic communities change as Quebec’s Romaine River flows into the sea.

Methane production, likely achieved by a diverse group of methanogenic archaea, occurs at similar rates in both alive and dead seagrasses, a study reports. The findings highlight the potential environmental impact of seagrasses declining globally.

Researchers discover that bacteria break down medicinal compounds for their nitrogen, solving a mystery that has vexed aquatic veterinarians for years.

Reconstructing the diet and microbiome of human ancestors shows an astonishingly rapid loss of microbiome diversity.

Centenarians have distinct microbiomes with species that produce unique bile acids, which may help thwart illness.

The gastrointestinal tracts of people with major depressive disorder harbor a signature composition of viruses, bacteria, and their metabolic products, according to the most comprehensive genomic and metabolomic analysis in depression to date.

From journeys into mines to explorations of volcanoes on the ocean floor, deep voyages reveal the richness of the planet’s deep biosphere.

Identification of new archaea species elucidates the domain’s unique  biology and sheds light on its relationship to eukaryotes.

In cooperation with its microbiome, the animal has genetic help in digesting blood and warding off pathogens.

The shotgun approach, typically thought to be the superior method, may substantially underestimate diversity in environments that have not already been classified, researchers find.
