Your Gut’s Microbiome, On a Chip
In APL Bioengineering, researchers describe how gut-on-a-chip devices can bridge lab models and human biology. Modeling the microbiome is particularly difficult because of its unique environmental conditions, but through creative design, gut-on-a-chip devices can simulate many of these properties, such as the gut’s anaerobic atmosphere, fluid flow, and pulses of contraction/relaxation. Growing intestinal cells in this environment means that they more closely resemble human biology compared to standard laboratory cell cultures.

Scientists have now developed a rhizosphere-on-a-chip with a transparent simulated soil structure that allows researchers to view how roots grow over time through the pores in the soil. Paired with specialized mass spectrometry techniques, scientist can also use the rhizosphere-on-a-chip to map the location of root-exuded molecules, like amino acids, without hurting the plant.
A New Approach Produces a 90-Fold Increase in Known Viral Taxa
Viruses play an essential role in regulating microbiomes. However, the use of metagenomics and metatranscriptomics have produced taxonomies of only a tiny proportion of the world’s viruses.
