The impact of micro-habitat fragmentation on microbial populations growth dynamics

This study investigates how micro-habitat fragmentation affects microbial population dynamics using an ecology-on-a-chip platform and time-lapse microscopy, revealing non-monotonic growth patterns with droplet size.

Droplet size and surface hydrophobicity enhance bacterial plasmid transfer rates in microscopic surface wetness

The paper investigates how droplet size and surface hydrophobicity influence plasmid transfer rates in microscopic surface wetness using Pseudomonas putida.

Inherent protection of bacteria from beta-lactam antibiotics by wet-dry cycles with microscopic surface wetness

The paper shows bacteria are more protected from beta-lactam antibiotics under wet-dry cycles with microscopic surface wetness due to salt concentration, slow growth, and antibiotic deactivation.

Two-way microscale interactions between immigrant bacteria and plant leaf microbiota as revealed by live imaging

The paper uses live imaging to study microscale interactions between immigrant bacteria and resident microbiota on leaf surfaces, finding significant co-localization and preferential attachment.

Virus survival in evaporated saliva microdroplets deposited on inanimate surfaces

This study investigates virus survival in saliva microdroplets on surfaces, finding higher survival in dry saliva compared to water or buffer, suggesting saliva components enhance virus persistence.

Bacterial survival in microscopic droplets

This study shows that bacterial survival on drying surfaces is enhanced by microdroplet formation around aggregates, observed across 13 bacterial species.
