A Romantic Genius? The Experience of Knowledge that Shaped Werner Heisenberg's Scientific Persona
In 1976, the year that Werner Heisenberg passed away, Armin Hermann published a short biography, titled Werner Heisenberg in Selbstzeugnissen und Bilddokumenten. Since then, historians and biographers have offered their accounts on Heisenberg's life and his contributions to modern physics. Many of these biographies present Heisenberg as a genius.

ABSTRACT This study describes the green synthesis, characterization, and biological evaluation of silver nanoparticles (AgNPs) obtained from green propolis (AgNPs‐PRO). Before nanoparticles synthesis, a hydroethanolic green propolis extract (GPE) was obtained through ultrasound‐assisted extraction and characterized by high‐performance liquid ...

Interaction Between Actin and Microtubules During Plant Development
ABSTRACT The dynamic interaction between actin filaments (AFs) and microtubules (MTs) plays a crucial role in regulating key developmental and physiological processes in plant cells, particularly in the formation of specialized cell types with distinct shapes and functions, such as pollen tubes, trichomes, and leaf epidermal cells.

PEK14: A Kinesin‐4 Necessary for Male‐Derived Fertility in Arabidopsis thaliana
ABSTRACT Of the 61 kinesins annotated in Arabidopsis thaliana, many are still without assigned function. Here, we have screened an insertional mutant library of Arabidopsis pollen‐expressed kinesins for fertility defects. Insertional mutants for three kinesins showed a significant reduction in seed set.
