An Open Database of Lunar Regolith and Simulants Properties

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Lunar regolith, the layer of unconsolidated material covering the Moon's surface, is central to the science and technology developed for the Moon, notably related to in‐situ science investigations, resource utilization, surface infrastructure, and mobility systems.

Performance of lunar shell structure for moonbase subjected to low gravity coupled with changing temperature

Fundamental Research
Temperature variations on the lunar surface can cause significant thermal stress and increase energy consumption within a lunar base. Thus, studying the thermal behavior of lunar structures over time and space is crucial.

Weight Loss Improves Predicted 10‐Year MACE and Type 2 Diabetes Risk, but Benefits Partially Rebound at 1 Year

Obesity, EarlyView.
ABSTRACT Objective This study aimed to quantify changes in predicted 10‐year risk for major adverse cardiovascular events (MACE) and type 2 diabetes (T2D) across weight loss, post–weight loss (Post‐WL), and 1‐year follow‐up and to determine whether trajectories varied by exercise modality.

Interplanetary frontiers: terraforming from an invasion science perspective

Oikos, EarlyView.
The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

Lunar Regolith Geopolymer Concrete for In-Situ Construction of Lunar Bases: A Review

Polymers
The construction of lunar bases represents a fundamental challenge for deep space exploration, lunar research, and the exploitation of lunar resources. In-situ resource utilization (ISRU) technology constitutes a pivotal tool for constructing lunar bases. Using lunar regolith to create geopolymers as construction materials offers multiple advantages as

Do cultural taboos regulate hunting in transitioning Indigenous communities? The case of the Idu Mishmi of Northeast India

People and Nature, EarlyView.
Abstract There is rising recognition of resource‐use rights of Indigenous Peoples and Local Communities (IPLCs) within wildlife conservation. Historically, sociocultural institutions ensured wildlife sustainability in many IPLC areas. However, the future viability of such institutions is uncertain as IPLCs change in response to external pressures and ...
