Laurasian Seaway History During the Early Jurassic From Quantitative Mineralogy and Detrital Zircon Dating

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract The Laurasian Seaway comprises a N‐S oriented trans‐Pangaean corridor linking Tethys to the Boreal Sea during the Jurassic, and direction of water flow has been the subject of considerable debate. The Llanbedr (Mochras Farm) borehole, Cardigan Bay Basin, Wales, is a uniquely informative record that comprises an expanded deep‐marine silty ...

New Finnlakevirus Isolate FLiP‐2 Provides Insight Into the Ecology of ssDNA Phages in Flavobacterium Hosts

open access: yesEnvironmental Microbiology, Volume 28, Issue 6, June 2026.
Despite the small genome size, ssDNA virus FLiP is remarkably well adapted to the seasonal variations of boreal fresh waters demonstrating excellent condition and host specific flexibility in its host interactions. FLiP plaques detected far from the original infection site represent a previously undescribed phenomenon, likely caused by the phage non ...

Feeding adult of Artemia salina (Crustacea-Branchiopoda) on the dinoflagellate Gyrodinium corsicum (Gymnodiniales) and the Chryptophyta Rhodomonas baltica

open access: yesBrazilian Archives of Biology and Technology, 2005
Experiments were carried out on feeding performance and survival rates of adult Artemia salina exposed to no axenic strains of the dinoflagellate Gyrodinium corsicum and of the Chryptophyta Rhodomonas baltica. Filtration rates on R.

Novel GH115 xylan α‐1,2‐glucuronidases with distinct preferences for xylan‐derived oligomers and polymers

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
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 ...

EU-Financed Peripheral Large-Scale Infrastructure Projects and the White Elephant Syndrome: the Example of Rail Baltica [PDF]

open access: yesRomanian Journal of European Affairs, 2018
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 ...

The Curious Case of CysE: Diversity and Distribution of Serine Acetyltransferases in Bacteria

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 94, Issue 5, Page 1092-1103, May 2026.
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

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
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

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
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.
