Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

On the Reification of Global Constraints [PDF]

open access: yes, 2012
We introduce a simple idea for deriving reified global constraints in a systematic way. It is based on the observation that most global constraints can be reformulated as a conjunction of pure functional dependency constraints together with a ...

Structural Capacity Constraints in Australia’s Housing Crisis: A System Dynamics Analysis of the National Housing Accord’s Unachievable Targets

open access: yesSystems
Australia’s National Housing Accord aims to deliver 1.2 million new dwellings between mid-2024 and mid-2029, representing 240,000 annual completions—a 37% increase above the 2024 baseline of 175,000.

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

open access: yesFEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

GERMANY’S LABOUR SHORTAGE: BETWEEN STRUCTURAL PRESSURE AND UNCERTAIN HORIZONS [PDF]

open access: yesGlobal Economic Observer
Germany is currently facing a profound labour shortage that transcends sectoral boundaries and reflects deeper demographic and structural transformations. Following a brief post-pandemic rebound, the German economy has entered a phase of stagnation and

Epigenetic reprogramming of lineage switching in cancer

open access: yesFEBS Letters, EarlyView.
Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

(De)Constructing Conflict: A Focused Review of War and Peace Journalism [PDF]

open access: yesConflict & Communication Online, 2006
This overview of the media and conflict literature and case study of media coverage of peace offers a framework and guidance for peace journalism. Many studies show media rarely report conflict neutrally.

‘Guide and Prejudice’— How Argonautes recognize targets across domains of life

open access: yesFEBS Letters, EarlyView.
Argonaute proteins use short nucleic‐acid guides to locate and regulate specific targets across all domains of life. Despite striking diversity—from human gene silencing to bacterial immune defence—all Argonautes share a conserved three‐stage recognition logic: guide‐directed sampling, progressive target pairing with a conformational checkpoint and ...
