LifeMet: Report on the 2024–2025 meteorite recovery expedition in Dronning Maud Land, Antarctica for the study of microbe–meteorite interactions

Meteoritics &Planetary Science, EarlyView.
Abstract Since the discovery of nine meteorites near the Yamato mountains in 1969, Antarctica has been recognized as a superb location for meteorite recovery. While Antarctic recovery expeditions prioritize meteorite preservation for mineralogical and planetary studies, meteorites are not typically collected for biological applications.

Stardust Mine: A 2024 gabbroic shergottite from Arizona, USA

Meteoritics &Planetary Science, EarlyView.
Abstract This study provides an initial characterization of Stardust Mine, a fresh gabbroic enriched shergottite collected in Arizona, USA, in September 2024 and is the first Martian meteorite to be unequivocably collected on US soil. Analysis was conducted on the type specimen and finds that Stardust Mine is composed of equal proportions of pyroxene ...

The Ames impact structure, Oklahoma: New radioisotopic constraints and implications for North American impact chronology

Meteoritics &Planetary Science, EarlyView.
Abstract The Ames impact structure (Oklahoma) is thought to have formed during the Ordovician Meteor Event, based on conodont biostratigraphy of its crater fill. Here, U–Pb zircon dates from its impact‐melt portion, conducted using secondary ion mass spectrometry and laser ablation–inductively coupled plasma–mass spectrometry (n = 37 spots), yield a ...

Consciousness Multiplied

Philosophy and Phenomenological Research, EarlyView.
ABSTRACT It is generally assumed that an ordinary human brain is associated with a single mind. Indeed, this assumption is so deeply rooted that it is rarely articulated explicitly, let alone questioned. However, as philosophers of mind have increasingly noticed, it turns out to rest on alarmingly shaky ground.

Root surface biomodification in periodontal therapy: Biological rationale and clinical applications

Periodontology 2000, EarlyView.
Abstract Regenerative periodontal therapy aims to form new cementum, periodontal ligament, and alveolar bone, all sealed by gingival tissue. The root surface acts as the wound margin during this regeneration process. Root surface biomodification (root conditioning/root decontamination), therefore, seems instrumental in promoting surface decontamination

Return of the ants: investigating temporal and spatial patterns of ant colonization in unsealed schoolyards

Restoration Ecology, EarlyView.
Abstract Introduction Urban soil unsealing, the removal of impervious surface layers, is increasingly promoted as a habitat restoration strategy to enhance ecosystem resilience in cities. Yet, its potential to support soil biodiversity from the onset remains underexplored.
