Advanced Science, EarlyView.High light exposure triggers an epidermis‐specific remodeling of mitochondria and ER in Arabidopsis, driven by chloroplast‐derived signals. Live‐cell imaging shows that HL rapidly suppresses mitochondrial motility, followed by fusion‐driven elongation and ER cisternal expansion.

Detailed opacity calculations for astrophysical applications
, 2017 Nowadays, several opacity codes are able to provide data for stellar structure models, but the computed opacities may show significant differences. In this work, we present state-of-the-art precise spectral opacity calculations, illustrated by stellar ...

Engineered Bacteria‐Vesicle Delivered Lactate Reprogramming Boosts Tumor Radiosensitivity
Advanced Science, EarlyView.We engineered a bacterial‐vesicular dual‐delivery platform that targets LOx to colorectal tumors, enabling lactate clearance, immune microenvironment remodeling, and microbiota modulation. This microbe–metabolism synergistic strategy effectively sensitizes colorectal cancer to radiotherapy, offering a promising approach to overcome radioresistance ...

Chemical abundance of comets [PDF]
Observations of NH2, (OI) and molecular ion spectra in comets represent virtually all of the volatile fraction of a comet nucleus. Their study leads to the N2, NH3, H2O, CO2, CO content of the nucleus, and thus to important constraints on models of comet

3D investigation and modeling of the geometric effects on porosity in packed beds
AIChE Journal, EarlyView.Abstract In porous beds, physical boundaries restrict particle arrangement, leading to inhomogeneous porosity. This paper reports on the porosity profiles that are the result of geometric effects on monodisperse packed beds in cylindrical and cubic arrangements. Special focus is given to the influence of edges and corners in cubic geometries.

Near-Earth Asteroids as Possible Parent Bodies of Meteor Streams [PDF]
Учёные записки Казанского университета: Серия Естественные науки, 2016 The genetic relationship of meteor streams with near-Earth asteroids (NEAs) is being actively studied. A genetic link with the asteroid is possible only for streams in which meteoroids have the geocentric speed smaller than 50 km/s, thereby meaning the ...

Crater Observing Bioinspired Rolling Articulator (COBRA)
Advanced Intelligent Systems, EarlyView.Crater Observing Bio‐inspired Rolling Articulator (COBRA) is a modular, snake‐inspired robot that addresses the mobility challenges of extraterrestrial exploration sites such as Shackleton Crater. Incorporating snake‐like gaits and tumbling locomotion, COBRA navigates both uneven surfaces and steep crater walls.
