A new species, S.T.Ibáñez & Muñoz-Schick, , is described for Chile, extending the southern distribution of the genus. Its position within the genus was confirmed by morphological and molecular data, discussed here. The new species was found in a coastal environment, new to the genus, and is geographically far removed from the other Chilean species, which are from the Andes. The formation where it occurs, known as lomas, acts as a biodiversity refuge in hyperarid environments. The presence of in this environment contributes to the evidence of a floristic connection between the Atacama Desert and the Neotropical Andes.

Objective: The goal of this study was to analyze and differentially diagnose the presence of two large holes noted in the parietal bones of an individual and the presence of traumatic lesions.
Materials: A partially mummified young adult female associated with the Chinchorro culture, 4000 BP, from the coast of the Atacama Desert (northern Chile).
Methods: The bone lesions were evaluated macroscopically and radiologically.

Global climate change exacerbates abiotic stresses, as drought, heat, and salt stresses are anticipated to increase significantly in the coming years. Plants coexist with a diverse range of microorganisms. Multiple inter-organismic relationships are known to confer benefits to plants, including growth promotion and enhanced tolerance to abiotic stresses.

Background And Aims: Nolana mollis is a dominant plant species in the hyperarid Atacama Desert. A previous hypothesis states that N. mollis owes its success to the condensation of atmospheric water from undersaturated air onto its leaf surfaces by exuded salts, and absorption of this water by its leaves, or by shallow roots following drip onto the soil surface; living roots of N.

The Atacama Desert is home to bacteria that use biofilms as a means of protecting themselves against the harsh environment. To inform research regarding this survival mechanism, we cultured and sequenced the genomes of three sp. isolates from Atacama Desert soil.

The Simons Observatory (SO) is a cosmic microwave background instrumentation suite in the Atacama Desert of Chile. More than 65,000 polarization-sensitive transition-edge sensor (TES) bolometers will be fielded in the frequency range spanning 27 to 280 GHz, with three separate dichroic designs. The mid-frequency 90/150 GHz and ultra-high-frequency 220/280 GHz detector arrays, fabricated at NIST, account for 39 of 49 total detector modules and implement the feedhorn-fed orthomode transducer-coupled TES bolometer architecture.
