Geochemical and petrographic re‐evaluation of ungrouped iron meteorites from Western Australia
Meteoritics &Planetary Science, EarlyView.Abstract Under the current classification scheme, ungrouped irons make up ~11% of all recognized iron meteorites. A further ~7% of iron meteorites are currently classified as simply “irons” and are yet to be fully classified. To potentially classify these meteorites, newer approaches, including either statistical modeling or advanced geochemical ...

X‐ray computed tomography study of terrestrial analog cores in preparation for Mars sample return
Meteoritics &Planetary Science, EarlyView.Abstract Mars Sample Return (MSR) is expected to transform planetary science by providing unprecedented access to pristine Martian material. Initial characterization in the sample receiving facility (SRF) will rely on nondestructive techniques such as X‐ray computed tomography (XCT) to document the condition, distribution, and internal features of ...

A non-invasive measure of minerals and electrolytes in tissue [PDF]
A system for collecting epithelial cells from the oral mucosa for the determination of ion concentration is discussed with application to the study of man's adaptation to microgravity.

Drelów, the 13th and latest meteorite fall in Poland—A typical L6 chondrite with shock veins
Meteoritics &Planetary Science, EarlyView.Abstract On Tuesday, February 18, 2025, at 18:04:14 local time, residents of Poland observed a bright fireball registered by many Polish fireball stations belonging to the Skytinel Network established a few months before by Mateusz Żmija. Thus, the meteoroid's orbit, atmospheric trajectory, and the strewn field were calculated, and over 70 fragments ...

Meteoritics &Planetary Science, EarlyView.Abstract Quartz and feldspar commonly develop planar microstructures due to shock metamorphism. These are generally investigated and indexed (identifying the crystallographic orientation along which they developed) using a universal stage (U‐stage) on a petrographic microscope.

Pinus‐derived membrane vesicles disrupt pathogenic metabolism in fungi
Plant Biology, EarlyView.Needle‐derived vesicles from pine trees impair fungal metabolism and growth, offering a sustainable strategy to control pine pitch canker disease. Abstract Much of what we know about the biological impacts of vesicles (MVs) is derived from Arabidopsis thaliana.
