Unlocking landscape transient dynamics: Integrating traditional ecological knowledge for enhanced analysis of land‐use changes and forest expansion in a Mediterranean ecosystem

open access: yesPeople and Nature, EarlyView.
Abstract The Industrial Revolution triggered rural abandonment in Europe and had a profound impact on land configuration and ecosystem dynamics, mainly the growth of forests at the expense of open agricultural habitats. However, rural abandonment has been asynchronous in space and time, depending on regional socio‐economic dynamics.

A Test of Spectroscopic Age Estimates of White Dwarfs Using Wide WD+WD Binaries

open access: yesThe Astrophysical Journal
White dwarf stars have been used for decades as precise and accurate age indicators. This work presents a test of the reliability of white dwarf total ages when spectroscopic observations are available. We conduct follow-up spectroscopy of 148 individual

The Expanding Role of Gene Sequencing in Shaping Fetal Therapies: Clinical and Ethical Considerations

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT In utero interventions are transformative in addressing genetic and anatomic conditions during fetal development. Next generation sequencing enables early genetic testing, playing a pivotal role in prenatal decision‐making by supporting risk stratification, precise and timely diagnosis, which directly informs eligibility for fetal surgical and

Advancing Extracellular Vesicle Research: A Review of Systems Biology and Multiomics Perspectives

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Extracellular vesicles (EVs) are membrane‐bound vesicles secreted by various cell types into the extracellular space and play a role in intercellular communication. Their molecular cargo varies depending on the cell of origin and its functional state.

A Decade of Post‐Fire Succession Amplifies the Effect of Wildfire on the Surface Radiation Balance and Permafrost Thaw in Subarctic Peatlands

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Increasing wildfire activity is driving permafrost thaw in subarctic peatlands across the southern Northwest Territories, but the key mechanisms and progression of thaw following fire remain poorly understood. In response, 10 years (2015–2024) of near‐continuous surface (four‐component radiation, wind, and snow) and subsurface measurements ...
