In Vitro Live Cell Imaging Reveals Nuclear Dynamics and Role of the Cytoskeleton During Asymmetric Division of Pollen Mitosis I in Nicotiana Benthamiana

Cytoskeleton, EarlyView.
ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...

The Blue Lurker WOCS 14020: A Long-period Post-common-envelope Binary in M67 Originating from a Merger in a Triple System

The Astrophysical Journal Letters
We present Hubble Space Telescope far-ultraviolet (FUV) spectra of a blue lurker–white dwarf (BL–WD) binary system in the 4 Gyr open cluster M67. We fit the FUV spectrum of the WD, determining it is a C/O WD with a mass of $0.7{2}_{-0.04}^{+0.05}$ M _ ...

Arabidopsis AUGMIN8 Contains Two Independent Microtubule Association Domains

Cytoskeleton, EarlyView.
ABSTRACT Plant cells create a plasma membrane‐associated network of microtubules that are nucleated by γ‐tubulin ring complexes primarily through microtubule‐dependent microtubule nucleation (MDMN). This dynamic array organizes into specific patterns in response to developmental and environmental cues to influence primary cell wall construction.

Atomic Diffusion and Pulsation in Post-Common-Envelope Binary Stars

, 2020
APPROVED I study the evolution of peculiar low-mass, evolved stars. Two groups of interest are the core-helium-burning hot subdwarfs and the shell-hydrogen-burning low-mass pre-white dwarfs. Stars in both groups have had previous interactions with a companion in order to remove most of their outer layers to leave the stars we see today.

Effects of joint geometric configurations on cyclic shear behavior of intermittent joints under constant normal stiffness conditions

Deep Underground Science and Engineering, EarlyView.
The present manuscript explored the effects of joint configurations on the cyclic shear behavior of intermittent joints for the first time. The cyclic shear response, shear strength degradation, dilation characteristics evolution, frictional property, fractal dimension, and dissipative energy were further analyzed during shear cycles, which is crucial ...

A Triple Scenario for the Formation of Wide Black Hole Binaries Such as Gaia BH1

The Astrophysical Journal
Recently, several noninteracting black hole–stellar binaries have been identified in Gaia data—for example, Gaia BH1, where a Sun-like star is in a moderately eccentric ( e = 0.44) 185 days orbit around a black hole.

Hydrophobic eutectic solvent‐engineered membranes for highly permeable, selective, and antifouling pharmaceutical removal from municipal wastewater

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Single‐step incorporation of a hydrophobic deep eutectic solvent (HDES) into polyethersulfone ultrafiltration membranes via non‐solvent induced phase separation creates selective, antifouling membranes for pharmaceutical removal. The HDES nanodomains enhance permeability, electrostatic interactions, and adsorption affinity, enabling efficient and ...

The Fate of Gaia’s Wide Binaries: Interplay of White-dwarf Recoil and Tidal Interactions

The Astrophysical Journal
White dwarfs (WDs) receive natal velocity boosts of ∼1 km s ^−1 due to recoil from asymmetric mass loss during the late asymptotic giant branch (AGB) stage.

Social Class Discrimination and Academic Success: A Person‐Centered Approach Among Adolescents Disadvantaged in Social Class

Journal of Adolescence, EarlyView.
ABSTRACT Introduction Prior research indicates that social class is strongly associated with academic outcomes such as GPA. However, little work explores the role that social discrimination plays in this relation. This study examined the link between social class discrimination and academic outcomes among high school students.
