A Cell So Minimal That It Challenges Definitions of Life | Quanta Magazine The newly described microbe represents a world of parasitic, intercellular biodiversity only beginning to be revealed by genome sequencing.

A newly discovered archaeal cell has a tiny genome and can’t metabolize biomolecules. It’s upending biologists’ definition of a living thing. β€œThese types of organisms have been found before, but not as extreme as this,” said microbiologist Thijs Ettema.

If you use Kraken for profiling microbial / environmental / ancient metagenomic data, please check this preprint where I benchmark filtering strategies of Kraken outputs on simulated microbial and environmental metagenomic samples, and provide recommendations for optimal filtering thresholds
