Alzheimers Dement
Abstract INTRODUCTION Alzheimer's disease (AD) and behavioral variant frontotemporal dementia (bvFTD) lack mechanistic biophysical modeling in diverse, underrepresented populations. Electroencephalography (EEG) is a high temporal resolution, cost‐effective technique for studying dementia globally, but lacks mechanistic models and produces non ...

Mineralogical Investigation of Mg‐Sulfate at the Canaima Drill Site, Gale Crater, Mars

Journal of Geophysical Research: Planets, Volume 128, Issue 11, November 2023., 2023
Abstract For the first time on Mars, the crystalline magnesium‐sulfate mineral starkeyite (MgSO4‧4H2O) was definitively identified using the CheMin X‐ray diffraction instrument at Gale crater. At the Canaima drill site, starkeyite along with amorphous MgSO4‧nH2O are among the “polyhydrated Mg‐sulfates” interpreted in orbital reflectance spectra.

Depositional and Diagenetic Processes of Martian Lacustrine Sediments as Revealed at Pahrump Hills by the Mars Hand Lens Imager, Gale Crater, Mars

Journal of Geophysical Research: Planets, Volume 128, Issue 5, May 2023., 2023
Abstract The Murray formation represents fine‐grained sedimentary deposition in lacustrine environments within Gale crater, Mars. Both the overall thickness of the Murray formation and its broad uniformity in sedimentary character suggest the potential for a long‐lived, groundwater‐supported lake system.

Biomineralization of ordered dolomite and magnesian calcite by the green alga Spirogyra

Sedimentology, Volume 70, Issue 3, Page 685-704, April 2023., 2023
Abstract The formation of ordered dolomite under Earth's surface conditions remains a challenge, although many researchers have now shown that microbes can facilitate the precipitation of this common mineral. This study provides the first evidence of dolomite biomineralization by the green alga Spirogyra (Zygnematales, Chlorophyta), a globally ...

Zircon Dates Long‐Lived Plume Dynamics in Oceanic Islands

Geochemistry, Geophysics, Geosystems, Volume 23, Issue 11, November 2022., 2022
Abstract In this contribution we report the first systematic study of zircon U‐Pb geochronology and δ18O‐εHf(t) isotope geochemistry from 10 islands of the hot‐spot related Galapagos Archipelago. The data extracted from the zircons allow them to be grouped into three types: (a) young zircons (0–∼4 Ma) with εHf(t) (∼5–13) and δ18O (∼4–7) isotopic mantle
