How the Sima de los Huesos was won

The Anatomical Record, Volume 307, Issue 7, Page 2225-2245, July 2024.
Abstract Although the first discovery of a human fossil in the Sima de los Huesos took place in 1976, systematic excavations did not begin there until 1984. Since then, this site has been continuously excavated in month‐long camps. The site is dated by different radiometric techniques to between 430,000 and 300,000 years ago.

La erupción de El Charco de 1712 (Cumbre Vieja, La Palma). Nuevas aportaciones petrográficas y mineralógicas.

Geogaceta
La erupción volcánica de 1712, de El Charco, es una de las peor conocidas de las 8 erupciones históricas de la isla de La Palma. Fue un evento principalmente estromboliano, con fases hidromagmáticas, durante el cual se abrieron múltiples bocas a lo ...

Volcanic Unrest After the 2021 Eruption of La Palma

Geophysical Research Letters, Volume 51, Issue 11, 16 June 2024.
Abstract La Palma, Canary Islands, had its largest historical eruption in 2021. From January 2022 to May 2023 there were >2,100 seismic events, primarily at depths ≤20 km, prompting us to update the deformation and modeling study, using interferometric synthetic aperture radar observations and a last generation interpretation tool.

Magmatic Storage and Volatile Fluxes of the 2021 La Palma Eruption

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 6, June 2024.
Abstract The 2021 La Palma eruption (Tajogaite) was unprecedented in magnitude, duration, and degree of monitoring compared to historical volcanism on La Palma. Here, we provide data on melt inclusions in samples from the beginning and end of the eruption to compare the utility of both melt and fluid inclusions as recorders of magma storage.

Enhancing Nitrate Removal With Industrial Wine Residue: Insights From Laboratory Batch and Column Experiments Using Chemical, Isotopic and Numerical Modeling Tools

Water Resources Research, Volume 60, Issue 5, May 2024.
Abstract Agricultural run‐off exposes recipient water bodies to nitrate (NO3−) pollution. Biological denitrification is a suitable method for removing NO3− in water resources that can be induced by the use of industrial organic liquid waste as an electron donor source.

The 2021 La Palma eruption: social dilemmas resulting from life close to an active volcano

Geology Today, Volume 40, Issue 3, Page 96-111, May/June 2024.
Damage and destruction caused by the 2021 eruption of the Tajogaite volcano on La Palma was unprecedented relative to other historical eruptions of the last century (1909, 1949, 1971, 2011) in the Canary Islands. The devastation caused by the eruption was not a result of eruption magnitude, which was only marginally larger than other historical events,

Mega‐Folding of a Basement During Incipient Intra‐Plate Continental Subduction (Alpine Central Iberia)

Tectonics, Volume 43, Issue 4, April 2024.
Abstract Metamorphic basements are usually considered rigid and isotropic at a large scale. However, basements contain inherited weaknesses that may potentially accommodate superimposed contraction (e.g., fault reactivation), and that favor fold nucleation (e.g., penetrative foliations).

Development of hydrogel‐based composite scaffolds containing eggshell particles for bone regeneration applications

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 112, Issue 1, January 2024.
Abstract This study describes the development and characterization of novel composite scaffolds, made of an alginate‐chitosan hydrogel matrix containing eggshell (ES) particles, for bone tissue engineering applications. Scaffolds with ES particles, either untreated or treated with phosphoric acid to create a nanotextured particle surface, were compared
