Limnology and Oceanography, Volume 70, Issue 11, Page 3155-3171, November 2025.Abstract Aerosol dust deposited on the nutrient‐deprived surface ocean can boost phytoplankton growth and oceanic carbon uptake. Low mineral solubility restricts the biological utilization of dust‐nutrients, thereby benefiting phytoplankton that actively dissolve dust.

CASPER‐AI: Machine Learning Applied to Active Collimation in Monolithic Arrays of SDDs
X-Ray Spectrometry, Volume 54, Issue 6, Page 813-818, November/December 2025.ABSTRACT Monolithic arrays of Silicon Drift Detectors (SDDs) have advanced X‐ray spectroscopy by providing excellent energy resolution and high rates at near ambient temperatures. Despite these benefits, they are affected by charge sharing (CS), where photogenerated charge clouds spread across adjacent channels.

L-DOPA influences transferrin-dependent iron release at the blood-brain barrier
Fluids and Barriers of the CNSIron dysregulation in the brain is a pathological hallmark of Parkinson’s disease (PD) and contributes to oxidative stress and neurodegeneration. How the blood-brain barrier (BBB), the principal regulator of brain iron homeostasis, is implicated in this ...

What Does Iron Mean to an Oligodendrocyte?
Glia, Volume 73, Issue 9, Page 1784-1804, September 2025.Main Points Iron is essential for oligodendrocyte (OL) biology and myelin production, with deficiencies leading to severe neurological impairments. Understanding iron trafficking in OLs is crucial for developing treatments for dysmyelinating conditions. ABSTRACT Iron is essential for life and plays a key role in multiple fundamental cellular functions.

Journal of Geophysical Research: Oceans, Volume 130, Issue 8, August 2025.Abstract The Southern Ocean today is a globally relevant sink for atmospheric carbon dioxide (CO2 ${\text{CO}}_{2}$), where the biological uptake of carbon through primary productivity is largely controlled by widespread iron (Fe) limitation. We analyze observations from a submesoscale‐resolving cross‐section of the Antarctic Circumpolar Current (ACC ...
