Applying Hpo Indices to Empirical Thermospheric Density Models During Geomagnetic Storms

open access: yesEarth and Space Science, Volume 13, Issue 2, February 2026.
Abstract Accurate atmospheric drag modeling is essential for precise orbit determination and prediction of Low Earth Orbit satellites. A key component is the thermospheric density, typically estimated using empirical models driven by geomagnetic activity indices such as the 3‐hr Kp or ap.

Overview of the Nephele Perturbed Parameter Ensemble for Aerosol‐Cloud Interactions in E3SMv3

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 2, February 2026.
Abstract Aerosol‐cloud interactions (aci) are the leading source of uncertainty in inferring climate sensitivity from the historical record. Earth system models (ESMs) struggle to represent aci because the processes responsible for these phenomena occur at much finer time and space scales than can be resolved by any ESM.

The power of the past: materializing collective memory at early medieval lordly centres

open access: yesEarly Medieval Europe, Volume 34, Issue 1, Page 34-69, February 2026.
The repurposing of earlier sites and monuments is an enduringly popular theme in early medieval archaeology, but in England it has attracted little interest among Late Saxon and early post‐Conquest studies. From the tenth century, however, an increasingly prevalent pattern is discernible of secular lords locating their power centres in relation to ...

Exploring the influence of lid region residues on fatty acid selectivity in a lipase originating from Rhizopus oryzae

open access: yesThe FEBS Journal, Volume 293, Issue 3, Page 878-893, February 2026.
Lipases are vital in modifying lipid substrates across industries such as food, cosmetics, and pharmaceuticals. Among their features, fatty acid selectivity is particularly important for industrial applications. Rhizopus oryzae lipase (ROL) stands out for its high selectivity and broad applicability.
