Microplastics as active modulators of Escherichia coli biofilm characteristics and their implications on the development of antimicrobial resistance

Biofilm
Microplastics are increasingly recognized as substrates that facilitate microbial colonization and may contribute to antimicrobial resistance, yet their role in shaping biofilm physiology remains poorly understood.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Towards a development approach to displacement

Forced Migration Review, 2017
To better respond to displacement, we need to adopt a medium- to long-term perspective rooted in development as well as humanitarian principles.

Displacements

, 2019
In this work we establish a theory of Calculus based on the new concept of displacement. We develop all the concepts and results necessary to go from the definition to differential equations, starting with topology and measure and moving on to differentiation and integration.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Farmwork and family: How mixed-status families influence the mental health of foreign born farmworkers

SSM - Mental Health
Immigrant agricultural workers, especially unauthorized workers, face a range of severe stressors, including isolation, chronic job insecurity, and marginalization, leading to higher rates of mental health issues compared to native-born populations. This

Why we need the concept of land-grab-induced displacement [PDF]

, 2014
This paper challenges the traditional threefold classification of forced migration, and proposes a new concept: land-grab-induced displacement. The concept sheds light on issues that are shrouded by the conventional typology.

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Displacement-enhanced continuous-variable entanglement concentration

, 2012
We study entanglement concentration of continuous variable Gaussian states by local photon subtractions enhanced by coherent displacements. Instead of the previously considered symmetric two-mode squeezed vacuum states, we investigate the protocol for ...
