PSMA8‐Containing 20S Proteasome Regulates Spermiogenesis and Male Fertility
Advanced Science, EarlyView.PSMA8 assembles s20S proteasome that degrades specific substrates in elongating spermatids. Degradation of s20S‐substrates activates translation of FXR1‐target mRNAs, which are essential for mitochondrial sheath formation and sperm morphogenesis.

The determination of the pyrethrins in pyrethrum concentrates in mineral oil
, 1946 A method is described for the determination of pyrethrin I in pyrethrum concentrates in light mid heavy mineral oils. The method is based that of Wileoxon as modified by Holaday and utilises the separation of chrysanthemum monocarboxylic acid and the ...

Advanced Science, EarlyView.A programmable 2048‐element circular ultrasound array combined with a compact acoustic lens produces a thin “sound sheet” over a large field of view, and records echoes with wide angular diversity across the ring aperture. Coherence‐enhanced beamforming converts full‐matrix data into high‐contrast tomographic slices, delivering near‐diffraction‐limited

Natural Variation of NAR5 Determines Nitrogenase Activity and the Yield in Soybean
Advanced Science, EarlyView.This study identified NAR5, a gene encoding a subtilisin‐like protease, that regulates nitrogenase activity in soybean nodules. Overexpressing NAR5 delayed nodule senescence, enhancing nitrogenase activity, yield, and low‐nitrogen tolerance. The elite haplotype NAR5HapI‐1 linked to superior nitrogenase activity and greater seed weight has been ...
