Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Cultivation and visualization of a methanogen of the phylum Thermoproteota
Nature, Published online: 24 July 2024; doi:10.1038/s41586-024-07631-6 We demonstrate that the ability to conserve energy coupled to methane production is not restricted to the Euryarchaeota and is much more widespread than originally thought.
Article Description
Conventional cultivation-based methods to measure microbial abundance are unsuitable for quantifying uncultured microorganisms that constitute the majority of microbial life in most environmental or medical samples. This problem is solved by the quantification approach described here, which combines fluorescence in situ hybridization (FISH) with rRNA-targeted probes and digital image analysis. By measuring the areas of probe-labeled biomass in randomly recorded image pairs, an unbiased estimate of the relative biovolume of the population of interest can be obtained. This approach expresses abundance as "biovolume fraction" (relative to the total biovolume of the whole microbial community). This value equals thet share of biochemical reaction space occupied by the quantified population and thus can be more relevant ecologically than absolute cell numbers (e.g., a few large cells can contain the same biovolume as many small cells). Another advantage lies in the complete independence of this method from the morphology of the quantified organisms. Regardless of whether the target microbes occur as single cells in plankton samples, as filaments, or as dense aggregate biofilms, this cultivation-independent method allows the composition of complex microbial communities to be determined.
