Modeling With Uncertainty Quantification Identifies Essential Features of a Non-Canonical Algal Carbon-Concentrating Mechanism

The paper develops a mathematical model of a non-canonical carbon-concentrating mechanism in the alga Cyanidioschyzon merolae, identifying key parameters that enable its function.

Pattern formation along signaling gradients driven by active droplet behaviour of cell groups

The paper shows that Dictyostelium cells form swarms that behave like active droplets, leading to clump deposition and differentiation through a 'musical chairs' mechanism.

Biophysical carbon concentrating mechanisms in land plants: insights from reaction-diffusion modeling

The paper uses reaction-diffusion models to predict the efficiency of biophysical carbon concentrating mechanisms in C3 land plants, finding that their effectiveness depends on membrane permeability and specific environmental conditions.

Divergent Protein Kinase A contributes to the regulation of flagellar waveforms in Leishmania mexicana

This study investigates the role of divergent PKA isoforms in regulating flagellar waveforms in Leishmania mexicana, showing their impact on swimming speed and waveform patterns.

Approximating carbon fixation - how important is the Calvin-Benson cycle steady-state assumption?

The paper evaluates the validity of assuming a steady-state for the Calvin-Benson cycle in photosynthesis models by simplifying an existing model.

Multi-layer Regulation of Rubisco in Response to Altered Carbon Status in Synechococcus elongatus PCC 7942

The paper investigates how Rubisco activity and organization respond to changes in carbon availability in Synechococcus elongatus PCC 7942, revealing their role in metabolic balancing.

Catalase protects against non-enzymatic decarboxylations during photorespiration

Catalase prevents carbon loss from photorespiration by inhibiting non-enzymatic decarboxylations of photorespiratory intermediates in Arabidopsis thaliana.

Overexpression of the chloroplastic 2-oxoglutarate/malate transporter in rice disturbs carbon and nitrogen homeostasis

This study overexpresses ZmOMT1 in rice, disrupting carbon and nitrogen homeostasis, but co-overexpression with ZmDiT2 mitigates growth defects.

Computer-assisted beat-pattern analysis and the flagellar waveforms of bovine spermatozoa

This paper introduces a high-fidelity computer-assisted beat-pattern analysis method for bovine sperm flagellar waveforms, demonstrating statistical comparisons and synthetic data generation.
