Micronuclei and Other Nuclear Abnormalities in Patella Limpet as Biomarkers of Cytogenotoxicity in Recreational Port Waters

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Over the past decades, the growth in human population and economic activities has led to an increase in maritime traffic. This rise puts additional pressure on marine environments, vessel fuel spills being considered to have a major impact on the ecosystem.

Spectral Evidence for Recent/Ongoing Activity in Mercury’s Praxiteles Basin

open access: yesThe Planetary Science Journal
Mercury’s surface, as revealed by the MESSENGER probe, lacks distinctive absorption features in the visible–near-infrared spectral range, except for hollows that display a 630 nm feature ascribed to sulfides.

Origin and early evolution of terrestrial planet atmospheres and oceans

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2019
Planet atmospheric compositions are determined by the availability of a gas species, its molecular weight and the mass (or gravity force) of a planet. Both Mercury and the Moon are not massive enough to hold any gas species to form an atmosphere.

100 Years of Element Zero: Andreas von Antropoff's Neutronium and the Naming of the Neutron

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Congratulations to the 100th Anniversary of the publication of Andreas von Antropoff's element 0, “–“! This contribution provides a historical account of the concept of element zero and the naming of the neutron. The concept of element zero is 100 years old, having a first documented appearance in a 1926 publication by Andreas von Antropoff, while the ...

Several Kilometers of Global Contraction on Mercury: A Sample‐Size Independent Assessment of Fault Strain

open access: yesAGU Advances
Mercury underwent global contraction due to the sustained cooling of the planet. Positive‐relief landforms, found widespread across Mercury, are thought to be the surface expressions of thrust faults accommodating the contraction.

TROPICAL FRENCH THEORY: Henri Lefebvre and the Reinvention of Urban Planning in Havana, Cuba (1968–1971)

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract Contributing to global urban history, planning theory and the geography of ideas, this article discusses the travels of Henri Lefebvre’s The Right to the City in the wake of May 1968, in France. That year, under the direction of Mario González and Max Baquero, a small team including the Italian architect Vittorio Garatti, French planner Jean ...

Evolution of the Mercurian Crust as Recorded in Carbon

open access: yesThe Planetary Science Journal
Mercury and other silicate bodies are essential for understanding planetary formation and evolution. The surface of Mercury is unique and enigmatic, yet this innermost planet remains the least explored.

Making Mining Licit: Gold, Commodification, and the Everyday Performance of Law in Colombia

open access: yesAmerican Anthropologist, EarlyView.
ABSTRACT Ethnographies of resource‐making have shown that the extraction of resource value from objects is premised on obviating the emplaced lifeworlds that surrounded objects before they traveled to consumer markets. Much of this literature looks at such supply‐chain disentanglement from the viewpoint of corporate and formal regulatory practices ...

Crustal thickness and lithospheric properties of Mercury constrained by gravity data

open access: yesGeo-spatial Information Science
The crust and lithosphere of Mercury record the footprints of exogenous and endogenous activities since its formation, and their physical properties provide important clues for understanding the overall evolution of Mercury.
