Subcellular visualization of the distribution of atmospheric dinitrogen fixed by Gluconacetobacter diazotrophicus bacteria in maize

The paper uses NanoSIMS imaging to visualize subcellular distribution of fixed nitrogen in maize inoculated with Gluconacetobacter diazotrophicus, showing nitrogen incorporation into chloroplasts.

Variation in drug penetration does not account for the natural resistance of Mycobacterium abscessus biofilms to antibiotic

This study investigates antibiotic susceptibility in M. abscessus biofilms and finds that reduced efficacy is not due to differences in antibiotic penetration but may involve other biofilm characteristics.
