Rapid Evolution of the Photosystem II Electronic Structure during Water Splitting
Photosynthetic water oxidation is a fundamental process that sustains the biosphere. A Mn_{4}Ca cluster embedded in the photosystem II protein environment is responsible for the production of atmospheric oxygen.

Nonresonant valence-to-core x-ray emission spectroscopy of niobium [PDF]
The valence-to-core (V2C) portion of x-ray emission spectroscopy (XES) measures the electron states close to the Fermi level. These states are involved in bonding, thus providing a measure of the chemistry of the material.

We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Biphasic effects of 17β-estradiol and xenoestrogens on dopaminergic neurons in developing zebrafish
Due to the increasing pollution of aquatic environments by estrogen-like chemicals (xenoestrogens (XEs)), it is crucial to investigate their bioaccumulation, ecological impact, and potential endocrine-disrupting effects on aquatic organisms.

Two-Mode Waveguide Characterization by Intensity Measurements from Exit Face Images
A method that characterizes two-mode waveguides whose modes cannot be selectively excited (such as buried waveguides) is presented and demonstrated. The theoretical results are presented for $N$ modes, although for the sake of simplicity, only the two ...

Structural biology of ferritin nanocages
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

On some permutation polynomials over finite fields
Let p be prime, q=pm, and q−1=7s. We completely describe the permutation behavior of the binomial P(x)=xr(1+xes) (1≤e≤6) over a finite field Fq in terms of the sequence {an} defined by the recurrence relation an=an−1+2an−2−an−3 (n≥3) with initial ...
