Optimal neuromuscular performance requires motor neuron phosphagen kinases

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Motor neuron (MN) terminals in fruit flies, mice and humans contain phosphagen kinases, a key enzyme in their energy storage and buffering system. Here we knocked down the primary phosphagen kinase in fruit fly larvae (arginine kinase 1 (ArgK1)) but were surprised to find that MN endurance was unaffected.

Long-Lived In-Situ Solar System Explorer (LLISSE): Potential Contributions to the Next Decade of Solar System Exploration [PDF]

open access: yes
Venus, while having similar size, mass, and location in the solar system to Earth, varies from Earth in many ways and holds many scientific mysteries despite many missions that have focused on it in the past.

Mixed-valence iron minerals on Venus: Fe(2+)-Fe(3+) oxides and oxy-silicates formed by surface-atmosphere interactions [PDF]

open access: yes
Inferences from these investigations are that Fe(3+)-bearing minerals such as hematite magnesioferrite, acmite, and epidote are thermodynamically unstable, and that magnetite is the predominant mixed-valence iron oxide mineral on venus.

Determinants of Household Adaptation to Climate Vulnerability in Wetland Areas of Bangladesh: An Empirical Estimation

open access: yesClimate Resilience and Sustainability, Volume 5, Issue 1, June 2026.
The study evaluated the vulnerability and adaptation status of farming households in the climate‐sensitive wetland region of Bangladesh, using survey data from 120 households. The livelihood vulnerability index indicated moderate vulnerability (0.53), with key risks stemming from livelihood strategies, natural resource dependence and climatic ...

Episodic plate tectonics on Venus [PDF]

open access: yes
Studies of impact craters on Venus from the Magellan images have placed important constraints on surface volcanism. Some 840 impact craters have been identified with diameters ranging from 2 to 280 km. Correlations of this impact flux with craters on the

Laser Ablation Sampling With Low‐Power Plasma: A LA‐MIP‐MS Instrument for Spaceflight

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 3, 15 February 2026.
ABSTRACT Rationale Inductively coupled plasma (ICP) is a commonly used ion source for mass spectrometry‐based chemical analysis of a wide range of materials. Traditional ICP ion sources use high power (> 1000 W) and significant gas flow (> 10 L/min), rendering them unsuitable for spaceflight, as they are too resource‐intensive for planetary spacecraft.
