Everything is chemistry: Challenges for a sustainable future
Mètode Science Studies Journal: Annual ReviewLearning to transform matter – whether by cooking food or turning minerals into materials for making tools – has been key to the development of human societies. Everything we are and do is in some way chemistry.

Modules with Simple Multiplicity Modules
Journal of Algebra, 1995 Let \(G\) be a finite group, \(\mathcal O\) be a complete local commutative noetherian ring with an algebraically closed residue field \(k\) of nonzero characteristic \(p\). Let \(M\) be an indecomposable \({\mathcal O}G\)-module with vertex \(P\), \(\delta\) be a local point of \(P\) on \(\text{End}_{\mathcal O}(M)\) and \(V\) be the multiplicity \(k_*

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)

Organoids in pediatric cancer research
FEBS Letters, EarlyView.Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Journal of Fluid Science and Technology, 2017 A numerical analysis, based on a novel physical quantity of the topology, is presented to specify the key flow leading into a vortex. This analysis traces the flow transition into a vortical flow in terms of local flow geometry (topology) specified by ...
