ROS in cancer therapy: the bright side of the moon

open access: yesExperimental and Molecular Medicine, 2020
Reactive oxygen species (ROS) constitute a group of highly reactive molecules that have evolved as regulators of important signaling pathways. It is now well accepted that moderate levels of ROS are required for several cellular functions, including gene

The Extent, Nature, and Origin of K and Rb Depletions and Isotopic Fractionations in Earth, the Moon, and Other Planetary Bodies

open access: yesThe Planetary Science Journal, 2022
Moderately volatile elements (MVEs) are depleted and isotopically fractionated in the Moon relative to Earth. To understand how the composition of the Moon was established, we calculate the equilibrium and kinetic isotopic fractionation factors ...

Large sulfur isotope fractionation in lunar volcanic glasses reveals the magmatic differentiation and degassing of the Moon

open access: yesScience Advances, 2021
The differentiation and degassing of the Moon are revealed in the sulfur isotopes of lunar lavas. Sulfur isotope variations in mantle-derived lavas provide important constraints on the evolution of planetary bodies.

Spectrophotometric and Topographic Correlations within the Mare Ingenii Swirl Region: Evidence for a Highly Mobile Lunar Regolith

open access: yesThe Planetary Science Journal, 2023
The spectrophotometric properties of two study areas in the Ingenii swirl region show that the combined effects of multiple processes are required to explain the regolith’s mineralogical and physical properties.

The Role of the Commercial Space Industry within the US National Security under the Trump Administration

open access: yesВестник Московского Университета. Серия XXV: Международные отношения и мировая политика, 2021
The US space activities from their inception have been closely connected with the private sector. However, only in 2010s private space companies have come to play a prominent role not only on the global market of space services but in the field of ...

Pre-landing Assessment of the Surface and Shallow Subsurface Thermal Setting of Mare Crisium of the Moon for the Heat Flow Measurement Planned on the Blue Ghost 1 Mission

open access: yesThe Planetary Science Journal, 2023
In 2024, under NASA’s Commercial Lunar Payload Services initiative, a robotic lander will touch down in Mare Crisium of the Moon and deploy a heat flow probe.

Generating and storing power on the moon using in situ resources

open access: yesProceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2021
The Moon Village and similar concepts are strongly reliant on in situ resource utilisation (ISRU). There is great interest in harvesting solar power using locally leveraged in situ resources as an essential facet of in situ infrastructure. Traditionally,

Collision Chains among the Terrestrial Planets. III. Formation of the Moon [PDF]

open access: yesThe Planetary Science Journal, 2021
In the canonical model of Moon formation, a Mars-sized protoplanet “Theia” collides with proto-Earth at close to their mutual escape velocity v esc and a common impact angle ∼45°.

Yearling proportion correlates with habitat structure in a boreal forest landbird community [PDF]

open access: yesPeerJ, 2020
Landbird vital rates, such as productivity and adult survivorship, can be estimated by modeling mist-netting capture data. The proportion in which an adult breeding bird is 1 year of age (a “yearling”), however, has been studied only minimally in a few ...
