23Na and 75As NMR Study of Antiferromagnetism and Spin Fluctuations on NaFeAs Single Crystals

open access: yes, 2011
We report the $^{23}$Na and $^{75}$As NMR studies on NaFeAs single crystals. The structure transition temperature $T_S$ (55 K) and the spin density wave (SDW) transition temperature $T_{SDW}$ (40.5 K) are determined by the NMR line splits.

Mechanisms of IgE‐mediated food allergy and the role of allergen‐specific B cells

open access: yesFEBS Letters, EarlyView.
Food allergy arises when allergen‐specific B cells preferentially produce immunoglobulin E (IgE) antibodies against harmless foods. This article explains the mechanisms driving IgE‐mediated reactions, highlights the central role of these B cells, and discusses how natural tolerance (NT) and oral immunotherapy (OIT) can reshape allergic immune responses.

Unearthing the reality of ‘Zombie energy systems’ in Africa’s energy transition

open access: yesEnvironmental Research: Energy
Africa’s energy transition is unique and complicated by—among other things—the pervasive presence of ‘Zombie Energy Systems’ (ZES). These are outdated, inefficient, and environmentally harmful energy systems that persist despite being obsolete (e.g.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

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

open access: yesFEBS 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

Defining a ‘Just Energy Investment’ for the ASEAN Just Transition

open access: yesEnvironmental and Sustainability Indicators
Governments across the world have been updating their energy and climate policies since the 2015 Paris Agreement. One common feature is the advent of long-term plans for a net-zero economy for 2050 and also in some cases to 2060.

Detection of circulating tumor DNA in colorectal cancer patients using a methylation‐specific droplet digital PCR multiplex

open access: yesMolecular Oncology, EarlyView.
We developed a cost‐effective methylation‐specific droplet digital PCR multiplex assay containing tissue‐conserved and tumor‐specific methylation markers. The assay can detect circulating tumor DNA with high accuracy in patients with localized and metastatic colorectal cancer.

Depoliticizing the Just Transition? A Discursive Analysis of EU Parliamentary Debates on the Just Transition Mechanism

open access: yesSocial Sciences
This article examines the discursive dynamics of depoliticization in the European Union’s ecological transition, focusing on the Just Transition Mechanism (JTM), a key instrument of the European Green Deal. Building on critical scholarship, we start from
