Microcalorimetry reveals bacterial motility as an expensive trait during starvation

This study measures the energetic cost of bacterial motility using microcalorimetry and finds it to be a significant portion of total metabolism during starvation.

Salmonids exhibit an acute behavioral response to heterothermal environments

This study quantifies how brown trout parr respond to rapid temperature changes by avoiding cold water and crossing warm water interfaces.

Widespread attraction of marine bacteria to the macroalgae-derived polysaccharide fucoidan

This study shows marine bacteria are attracted to fucoidan at high concentrations, suggesting it guides them to macroalgal surfaces, influencing carbon cycling.

Bacterial capture and lysis on diatom spines reveal a suspension-feeding strategy

This study shows diatom spines capture and lyse bacteria, enabling nutrient acquisition and revealing a suspension-feeding strategy in phytoplankton.

Precise 3D Tracking of Highly Non-planar Eukaryotic Flagellar Beating Patterns using Digital Holographic Microscopy

This paper introduces holoV3C, a method for precise 3D tracking of non-planar eukaryotic flagella using DHM, achieving high temporal and axial resolution for flagellar dynamics analysis.

Emergent spatial structure in the gut microbiota is driven by bacterial growth and gut contractions

The paper shows how spatial structure in the gut microbiota emerges through bacterial growth in the matrix of gut content.

Growth in Low Carbon Conditions Reveals Amino-Acid-Coupled Iron Uptake

The paper studies bacterial iron acquisition under low carbon conditions and finds that amino acids facilitate iron uptake by E. coli.

Opposing range-dependent interactions create complex spatial patterns of antibiotic tolerance in multispecies biofilms

The paper shows that opposing range-dependent interactions between microbial exoproducts create complex spatial patterns of antibiotic tolerance in biofilms.

Limits to the evolution of metabolic dependence in spatially structured microbial communities

The paper investigates how auxotrophic mutants in E. coli populations grow in spatially structured communities, finding that growth is constrained by amino acid leakage and clustering.

Heritable diel energy reserves enhance diatom growth

This paper demonstrates that heritable diel energy reserves in diatoms enhance growth by allowing rapid division during the dark phase, leading to a significant increase in population abundance.

Breaching the diatom frustule: Alteromonas macleodii triggers protoplast emergence and programmed necrotic-like cell death in the oceanic diatom Thalassiosira rotula

This study shows Alteromonas macleodii breaches diatom shells, induces protoplast emergence, and triggers programmed necrotic-like cell death in Thalassiosira rotula, revealing a novel algicidal strategy.

Bacteria induce an amoeboid phase in coccolithophores that persists after bloom collapse

The paper identifies an amoeboid phase in coccolithophores triggered by bacteria, which persists after bloom collapse and may provide bacterial resistance.

GUARDIANS OF THE CELL: COCCOSPHERE PREVENTS OPPORTUNISTIC BACTERIA ATTACK IN HEAVY CALCIFYING COCCOLITHOPHORE

This study shows that the coccosphere of Coccolithus braarudii prevents bacterial attack by Phaeobacter inhibens, as decalcified cells become susceptible to pathogenic interactions.

Synergy in viral-bacterial coinfection expedites algal bloom demise

The paper identifies bacterial-viral synergy as a key factor in algal bloom termination, showing how bacteria enhance viral infection and influence carbon cycling pathways.

Extracellular polymeric substance degradation shapes microbial community diversity

The paper shows that EPS from chitin degradation influences microbial community diversity by supporting different consumer types through sequential breakdown.

Antagonism as a foraging strategy in microbial communities

The paper shows bacteria use contact-dependent antagonism to acquire nutrients by lysing neighbors during starvation, enhancing growth in spatially structured environments.

Risk-reward trade-off in motility endurance generates dichotomy in search strategies among copiotrophic marine bacteria

The paper identifies a risk-reward trade-off in motility endurance among copiotrophic marine bacteria, revealing two distinct strategies with genomic predictors.
