Biochemical Barriers on the Path to Ocean Anoxia?

The paper proposes the Hypoxic Barrier Hypothesis to explain why ocean oxygen levels remain higher than expected despite microbial respiration, finding a large variation in oxygen affinity among enzymes.

Ribosome elongation kinetics of consecutively charged residues are coupled to electrostatic force

The paper shows charged residues affect ribosome elongation speed through mechanochemical forces, supported by simulations and experimental data.

Oxygen supply capacity in animals evolves to meet maximum demand at the current oxygen partial pressure regardless of size or temperature

The paper shows that oxygen supply capacity matches maximum metabolic demand at current oxygen pressure, regardless of size or temperature, and redefines physiological concepts.
