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

open access: yesMeteoritics &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.

Research on Non-Linearity Percolation Characteristics in Tight Sandstone Gas Reservoir [PDF]

open access: yes, 2015
The microcosmic pore throat structure is complex in tight sandstone reservoir so that the fluid lodging situation and flow condition in the pore space is difficult to determine, which has an influence on the effective displacement and efficient ...

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

open access: yesMeteoritics &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 ...

Advancing the pneumatic method to assess xylem vulnerability to embolism among distinct growth forms

open access: yesPlant Biology, EarlyView.
Our study shows that pneumatic vulnerability curves can be constructed across contrasting growth forms, with P50 showing the closest agreement across methods. Repeated relative water content measurements improved water potential estimation for graminoid culms. Abstract Drought‐driven plant mortality is closely linked to xylem embolism. Building useful,

Alternative approaches to dryland reclamation enhance vegetation cover and soil stability at a former uranium mine

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Conventional reclamation methods to recover dryland ecosystems after mineral extraction often have low success. Alternative reclamation techniques may help overcome the many challenges to establishing persistent native vegetation and stable soils.
