Sensing and Filtering Environmental Fluctuations: The Case of Biomolecular Condensates in Plants
Advanced Science, Volume 13, Issue 27, 13 May 2026.The diversity of plant condensates reflects constraints of sessile organisms to coordinate postembryonic development with environmental adaptation. This review examines how plants employ condensates to integrate temperature, light, redox, and nutrient signals.

Arrhenius parameters of the bacteriorhodopsin photocycle in dried oriented samples
, 1985 In dried oriented samples of purple membranes isolated from Halobacterium halobium the Arrhenius parameters of the photocycle showed an abrupt change at a water content of approximately 80 H2O molecules per bacteriorhodopsin molecule. This makes probable

Egg yolk hydrolysate shows moderate impact on osteoporosis in ovariectomized rats
Journal of the Science of Food and Agriculture, Volume 106, Issue 7, Page 4218-4227, May 2026.Abstract BACKGROUND This study investigated the protective effect of egg yolk hydrolysate (FC) on osteoporosis in ovariectomized (OVX) rats, a well‐established model of postmenopausal bone loss. OVX rats were fed diets supplemented with 0.2% or 1% FC for 13 weeks.

Steady-State Characterization of Bacteriorhodopsin-D85N Photocycle
, 1999 An operational characterization of the photocycle of the genetic mutant D85N of bacteriorhodopsin, BR-D85N, is presented. Steady-state bleach spectra and pump-probe absorbance data are obtained with thick hydrated films containing BR-D85N embedded in a ...

Confinement in crystal lattice alters entire photocycle pathway of the Photoactive Yellow Protein
, 2020 Femtosecond time-resolved crystallography (TRC) on proteins enables resolving the spatial structure of short-lived photocycle intermediates. An open question is whether confinement and lower hydration of the proteins in the crystalline state affect the ...
