Beyond Skin and Eyes: The Medical and Social Burden of Oculocutaneous Albinism in Africa: A Narrative Review

JEADV Clinical Practice, EarlyView.
ABSTRACT Oculocutaneous albinism (OCA) is a genetic disorder found worldwide, but its impact is particularly pronounced in the African continent. This results from both a higher prevalence and the persistent myths and superstitions surrounding the condition in many African communities.

Forecasting the occupancy of satellite megaconstellations in SKA observations

Astronomy & Astrophysics
The Square Kilometre Array (SKA) is expected to start science operations in 2030 and by that time there could be up to 105 artificial satellites in Earth’s orbit, comprising an increase of an order of magnitude compared to 2024.

Cis–Trans Rotational Isomerism of Formic Acid, Sulfur, and Selenium Analogues and Their Dimers: Chemical Kinetics Under Interstellar Conditions

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT We present chemical kinetic rate constants for the cis to trans isomerisation or rotamerization of monomeric seleno‐, thio‐, and formic acids and that of three of their dimeric species, based on variational transition state theory and multidimensional tunneling calculations in the gas‐phase, from 10 K to 300 K. These provide, firstly, reliable

Nitrogen Enrichment Enhances Soil Multifunctionality Through Distinct Drivers Across Urban, Suburban, and Rural Forests

Land Degradation &Development, EarlyView.
ABSTRACT The accelerating pace of urban expansion has profoundly reshaped urban–rural ecosystems, altering soil environments and impairing key ecological services. However, the combined impacts of urban expansion and atmospheric nitrogen (N) deposition on soil multifunctionality—the capacity to sustain multiple ecological processes—remain poorly ...

Multi-map holography for large crossed-Dragone telescopes

Astronomy & Astrophysics
We present a novel microwave holography technique for large crossed-Dragone telescopes, which feature two similarly sized off-axis reflectors whose surface deformations must be measured and corrected independently.

A novel approach for in situ benthic habitat characterization

Limnology and Oceanography: Methods, EarlyView.
Abstract Habitat heterogeneity is a key driver of temporal and spatial variability of subtidal marine benthic biodiversity. However, this makes it a challenging environment in which to measure and quantify the factors driving biodiversity in a consistent manner.

Deterministic Fiber‐Optic Spectral Engineering Enables Three‐Color Multiplexed Two‐Photon Microscopy

Laser &Photonics Reviews, EarlyView.
A simulation‐guided spectral‐engineering framework maps the nonlinear parameter space of a fiber laser platform to identify balanced three‐band excitation states. The resulting 960, 1080, and 1175 nm femtosecond pulses deliver nJ‐level energies for low‐cross‐talk chromatically multiplexed two‐photon microscopy.
