Multiple dinosaur egg-shell occurrence in an Upper Cretaceous nesting site from Patagonia [PDF]

, 2010
The discovery of hundreds of megaloolithid-type egg-clutches (some including embryos of an indeterminate species of titanosaur sauropods) in several stratigraphical levels of the Late Cretaceous nesting site of Auca Mahuevo (Chiappe et al., 2005 ...

Simple Detection of Imperfect Charge Extraction at Contacts – Application to Perovskite Solar Cells

Advanced Energy Materials, Volume 15, Issue 48, December 23, 2025.
A novel analytical method is introduced to quantify imperfect charge extraction at solar cell interfaces using internal quantum efficiency measurements under weak and strong absorption. Applied to highly efficient perovskite solar cells, the method reveals imperfect interfacial collection, enabling rapid evaluation and detection of efficiency ...

Structural and Functional Properties of Araucaria araucana and Araucaria angustifolia Seed Proteins as a Plant‐Based Food Source

Sustainable Food Proteins, Volume 3, Issue 4, December 2025.
Morphologically, A. angustifolia seeds were significantly larger, while A. araucana exhibited more regular, triangular shapes. Proximate composition revealed a carbohydrate‐rich profile in both species, with a significantly higher lipid content in A. araucana. Amino acid analysis showed similar profiles, with high levels of aspartic and glutamic acids.

Changes in Motion of the Nazca/Farallon Plate Over the Last 34 Million Years: Implications for Flat‐Slab Subduction and the Propagation of Plate Kinematic Changes

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract A high‐resolution sequence of finite‐rotation solutions spanning the past 34 Myr for the Nazca plate relative to the Pacific, Antarctic, and South American plates shows a pattern of 1–5‐Myr‐long intervals of nearly constant plate motion mostly separated by decelerations or accelerations lasting no longer than a few hundred thousand years ...

Assembling for Water: The Prefigurative Politics of Land Futures in Argentina

Antipode, Volume 57, Issue 6, Page 2213-2240, November 2025.
Abstract As in other areas of Argentina, residents from the Norte Neuquino in the northwestern reaches of Patagonia are concerned about the recent advancements of extractivism onto their territories. Their analysis is clear: the environmental crisis is directly linked to a democratic one, and they engage in a wide range of actions to envision and enact

Modeling Overpressure Development and the Mechanical Behavior of Sediments in a Complex, Tectonically Active Setting: East Coast Basin, New Zealand

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract The East Coast Basin (ECB) is a complex, active convergent margin located on the North Island of New Zealand, where variable but commonly very high overpressures occur in Cretaceous to Pleistocene stratigraphy. Using a consistent set of sediment physical properties and a single value for tectonic compression, a multi‐1D hydro‐mechanical ...
