Twisted Tin‐Chloride Perovskite Single‐Crystal Heterostructures

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.
Replacing lead with tin in a single‐crystal halide perovskite heterostructure drives a twist between the perovskite (gray) and intergrowth (blue) layers. The accompanying structural distortions and interfacial strain change the calculated orbital composition of the band edges and enable high in‐plane optical anisotropy in the Sn analog.

An atlas of plant selenium metabolism

New Phytologist, Volume 250, Issue 4, Page 2041-2060, May 2026.
Summary Selenium (Se) is not only a rare and toxic element but also an essential micronutrient for humans and animals that is often in short supply. Terrestrial plants do not require Se, but it can have growth‐promoting or negative effects, depending on the exposure level.

YidC and SecYEG form a heterotetrameric protein translocation channel

Scientific Reports, 2017
The heterotrimeric SecYEG complex cooperates with YidC to facilitate membrane protein insertion by an unknown mechanism. Here we show that YidC contacts the interior of the SecY channel resulting in a ligand-activated and voltage-dependent complex with ...

Two-way communication between SecY and SecA suggests a Brownian ratchet mechanism for protein translocation

eLife, 2016
The essential process of protein secretion is achieved by the ubiquitous Sec machinery. In prokaryotes, the drive for translocation comes from ATP hydrolysis by the cytosolic motor-protein SecA, in concert with the proton motive force (PMF). However, the

Trapped lipopolysaccharide and LptD intermediates reveal lipopolysaccharide translocation steps across the Escherichia coli outer membrane [PDF]

, 2015
Lipopolysaccharide (LPS) is a main component of the outer membrane of Gram-negative bacteria, which is essential for the vitality of most Gram-negative bacteria and plays a critical role for drug resistance.

Tn‐seq of Thermus thermophilus Genome Reveals Unexpected Tolerance to Insertions in Bacterial Common Essential Genes

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
Tn‐seq analysis of Thermus thermophilus genome reveals insertions in almost all genes, this is, there is no clear discrimination of essential genes. A similar result has not been reported in other Tn‐seq analysis of bacterial genomes so far. The polyploidy of the Thermus genome could explain the apparent non‐essentiality of key genes.

Dynamic nature of SecA and its associated proteins in Escherichia coli.

Frontiers in Microbiology, 2015
Mechanical properties such as physical constraint and pushing of chromosomes are thought to be important for chromosome segregation in Escherichia coli and it could be mediated by a hypothetical molecular tether.

OsPT4 Facilitates Selenomethionine Transport and Biosynthesis to Enhance Seed Accumulation in Rice: Molecular Mechanisms and Biotechnological Potential

Plant Biotechnology Journal, Volume 24, Issue 4, Page 1992-2008, April 2026.
ABSTRACT Selenium (Se) is a vital micronutrient for humans, with important functions for health and anti‐cancer properties. Organic Se shows higher antioxidant activity and much lower toxicity compared to inorganic Se, making it safer for use. Selenomethionine (SeMet) is one of the primary forms of organic Se.

First isolation and direct evidence for the existence of large small-mammal reservoirs of Leptospira sp. in Madagascar. [PDF]

PLoS ONE, 2010
BACKGROUND: Leptospirosis has long been a major public health concern in the southwestern Indian Ocean. However, in Madagascar, only a few, old studies have provided indirect serological evidence of the disease in humans or animals. METHODOLOGY/PRINCIPAL
