Plastic Odyssey calls at the Port of Sansouci in Santo Domingo, Dominican Republic, from August 28 to September 22, 2023, continuing its exploration of solutions to plastic pollution in the Caribbean region

, 2023
[Press release]. In October 2022, the ship Plastic Odyssey set off on a 3-year expedition around the world from the Port of Marseille. After several stopovers in the Mediterranean (Lebanon, Egypt, Tunisia, Morocco) and West Africa (Senegal, Guinea, Cape ...

Structural and biochemical analysis of a B12 superbinder

FEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

FEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Interplay of Martensitic Phase Transformation and Plastic Slip in Polycrystals [PDF]

, 2013
Inspired by key experimental and analytical results regarding Shape Memory Alloys (SMAs), we propose a modelling framework to explore the interplay between martensitic phase transformations and plastic slip in polycrystalline materials, with an eye ...

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

FEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Reducing Single-Use Plastic Products in Vietnam Tourism: Case Studies of Quang Nam and Ninh Binh Provinces [PDF]

Nature Environment and Pollution Technology
Plastic waste (PW) pollution has become a pressing global issue. The tourism sector is significantly affected by PW but is also a major contributor to PW. This is mainly due to the widespread use and disposal of single-use plastic products (SUP).

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Print media discursive practices and the socio-contextual representation of single-use plastics ban in Malawi

Cogent Arts & Humanities
This paper analyses the coverage and socio-contextual representation of the single-use plastics ban by two mainstream newspapers in Malawi, The Daily Times and The Nation Newspapers, between January 2019 and December 2022.
