Evidence from Rb–Sr mineral ages for multiple orogenic events in the Caledonides of Shetland, Scotland [PDF]
Shetland occupies a unique central location within the North Atlantic Caledonides. Thirty-three new high-precision Rb–Sr mineral ages indicate a polyorogenic history.

Abstract Natural polymers are promising sustainable materials for diverse applications. Xylans, major components of hemicellulose, exhibit origin‐dependent substitution patterns that determine their physicochemical properties. Targeted enzymatic modification of these substituents offers a mild and precise approach for tailoring the polymer's ...

The Curious Case of CysE: Diversity and Distribution of Serine Acetyltransferases in Bacteria
ABSTRACT Serine acetyltransferase (CysE) is a member of the left‐handed β‐helix family of acetyltransferases that catalyze the rate limiting step in de novo cysteine biosynthesis. There are two isoforms of CysE that differ in length, with the shorter isoform lacking approximately 76 amino acids at the N‐terminus of the protein from the serine ...

Cryptic Paleomagnetic Complexity in the Ediacaran Egersund Dikes
Abstract The Ediacaran Period (∼635–539 Ma) represents a critical interval in Earth's evolution, yet its paleomagnetic record remains complex and contentious. One of the few Ediacaran paleomagnetic results from Baltica considered robust is a pole from the ca.

Ediacara Obscura: Unveiling Hidden Magnetisations in the Fen Complex, Southern Norway
Abstract Paleomagnetic directions found in Ediacaran (635–539 Ma) rocks are widely dispersed, which has led to conflicting hypotheses about tectonic regimes and geomagnetic field behavior during this period, and raised doubts about the fidelity of the paleomagnetic record.

EU-Financed Peripheral Large-Scale Infrastructure Projects and the White Elephant Syndrome: the Example of Rail Baltica [PDF]
The present article revolves around the question of the appropriateness of “the white elephant syndrome” to characterize the nature of the planned trans-Baltic railway project Rail Baltica in terms of its initial financing, long-term profitability and ...
