Background assessment for the TREX dark matter experiment [PDF]
AbstractTREX-DM is conceived to look for low-mass Weakly Interacting Massive Particles (WIMPs) using a gas Time Projection Chamber equipped with Micromegas readout planes at the Canfranc Underground Laboratory. The detector can hold in the active volume$$\sim 20~l$$∼20lof pressurized gas up to 10 bar, corresponding to 0.30 kg of Ar or 0.16 kg of Ne ...

Picking a way forward: valuing and managing traditional shellfish gathering for Littorina littorea
Littorina littorea (periwinkles) have been harvested by hand picking from the shore since prehistoric times. Harvests are generally unregulated, catches are not linked to particular shores and fisheries statistics are considered to be unreliable.

Structural basis for high-order complex of SARNP and DDX39B to facilitate mRNP assembly
Summary: mRNA in eukaryotic cells is packaged into highly compacted ribonucleoprotein particles (mRNPs) in the nucleus and exported to the cytoplasm for translation.

Cryo-EM structure of the yeast TREX complex and coordination with the SR-like protein Gbp2
The evolutionarily conserved TRanscript-EXport (TREX) complex plays central roles during mRNP (messenger ribonucleoprotein) maturation and export from the nucleus to the cytoplasm. In yeast, TREX is composed of the THO sub-complex (Tho2, Hpr1, Tex1, Mft1,

Molecular insights into mRNA export regulation by the human TREX-2 complex
The nuclear export of mRNA represents a critical regulatory node in eukaryotic gene expression. This process is orchestrated by two conserved multi-subunit assemblies: the transcription-and-export complex (TREX) and TREX-2.

Prion‐Like Protein LENG8‐Mediated Nucleation Drives Stress Granule Assembly
LENG8 is a newly identified stress granule (SG) nucleator required for SG assembly. Following stress, nuclear LENG8 granules disassemble, allowing LENG8 to translocate into the cytoplasm and form independent nucleation foci. These foci fuse with canonical early G3BP1/TIA1 seeds via LENG8‐TIA1 binding to drive SG maturation.

Structural mechanism of DDX39B regulation by human TREX-2 and a related complex in mRNP remodeling
Nuclear export of mRNAs in the form of messenger ribonucleoprotein particles (mRNPs) is an obligatory step for eukaryotic gene expression. The DEAD-box ATPase DDX39B (also known as UAP56) is a multifunctional regulator of nuclear mRNPs.

Drivers and Challenges of Micro‐Irrigation Adoption and Intensity in India: A Study of Four States
ABSTRACT India's food security relies substantially on groundwater, but inefficient irrigation is seriously depleting this resource. Micro‐irrigation (MI) improves irrigation application efficiency and productivity, yet adoption remains low. This study examines MI adoption across four major Indian states—Uttar Pradesh, Maharashtra, Madhya Pradesh and ...
