Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

The Alabama Revisited: Some Observations on the Evolution of Rights and Duties of Neutral States in Armed Conflicts under International Law

Acta Universitatis Lodziensis Folia Iuridica
The paper discusses the concept of neutrality in contemporary international law. The traditional notion of neutrality, stemmed from states’ practice since the 17th century, means the particular status, defined by international law, of a state that is not
