Paleoneuroanatomy of the European lambeosaurine dinosaur Arenysaurus ardevoli [PDF]

open access: yes, 2015
The neuroanatomy of hadrosaurid dinosaurs is well known from North America and Asia. In Europe only a few cranial remains have been recovered that include the braincase. Arenysaurus is the first European endocast for which the paleoneuroanatomy has been

Achieving Photo‐Activated Circularly Polarized Room Temperature Phosphorescence from Natural Biopolymers

open access: yesAdvanced Science, Volume 13, Issue 10, 18 February 2026.
This bio‐based chiral luminescent system exhibit photo‐activated CPRTP by anchoring arylboronic acids to hydroxypropyl cellulose (HPC) matrix. Notably, by controlling the drying kinetics, dynamic switchable CPRTP with opposite handedness can be obtained due to a balance of photonic bandgap (PBG) effect and chirality transfer effect induced by the HPC ...

The evolutionary history of sharp- and blunt-snouted lenok (Brachymystax lenok (Pallas, 1773)) and its implications for the paleo-hydrological history of Siberia [PDF]

open access: yes, 2008
Background Broad-scale phylogeographic studies of freshwater organisms provide not only an invaluable framework for understanding the evolutionary history of species, but also a genetic imprint of the paleo-hydrological dynamics stemming from climatic ...

A Universal Genomic Approach to Detect Hybridization Using MIPs: Insights From a Case Study on Pike

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Interspecific hybridization poses a major challenge to biodiversity conservation, as genetic introgression can threaten the persistence of native species. This phenomenon occurs when individuals from distinct species interbreed, producing hybrids with a combination of genetic traits from both parents. The implications are especially concerning

Spatial variability in iron nutritional status of large diatoms in the Sea of Okhotsk with special reference to the Amur River discharge [PDF]

open access: yes, 2014
The Sea of Okhotsk is known as one of the most biologically productive regions among the world's oceans, and its productivity is supported in part by the discharge of iron (Fe)-rich water from the Amur River.

Sunlight‐Driven Fixation of CO2 to Cyclic Carbonates Using Carbon Dots as a Photothermal Catalyst

open access: yesExploration, Volume 6, Issue 1, February 2026.
The first example using carbon dots (CDs) for coupling CO2 with epoxides to generate cyclic carbonates in a metal‐, additive, solvent‐ and electricity input‐free manner under sunlight via photothermal catalytic route is developed. The CDs exhibit highly efficient solar‐to‐thermal conversion with an efficiency of 54%, providing thermal energy for ...

DeepRec: Global Terrestrial Water Storage Reconstruction Since 1941 Using Spatiotemporal‐Aware Deep Learning Model

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Terrestrial water storage (TWS) plays an important role in describing the Earth system, as water availability is decisive for ecosystems and human development. Since 2002, the Gravity Recovery and Climate Experiment (GRACE) and its Follow‐On (GRACE‐FO) mission have measured TWS anomalies with unprecedented accuracy, enabling a leap in ...
