Plasticity of Gene Expression in Spaceflight and Postflight in Relation to Cardiovascular Disease: Mechanisms and Candidate Repurposed Drugs

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Spaceflight poses unique challenges to human health due to exposure to increased levels of cosmic radiation, microgravity, and associated oxidative stress. These environmental factors can lead to cellular damage, inflammation, and a range of health complications, including cardiovascular problems, immune system impairment, and an increased ...

Media ion composition controls regulatory and virulence response of Salmonella in spaceflight. [PDF]

open access: yesPLoS ONE, 2008
The spaceflight environment is relevant to conditions encountered by pathogens during the course of infection and induces novel changes in microbial pathogenesis not observed using conventional methods. It is unclear how microbial cells sense spaceflight-

Limits and signatures of relativistic spaceflight [PDF]

open access: yesActa Astronautica, 2018
While special relativity imposes an absolute speed limit at the speed of light, our Universe is not empty Minkowski spacetime. The constituents that fill the interstellar/intergalactic vacuum, including the cosmic microwave background photons, impose a lower speed limit on any object travelling at relativistic velocities. Scattering of cosmic microwave

Space Economy and Sustainability: A Systematic Review

open access: yesSustainable Development, EarlyView.
ABSTRACT The space economy is booming thanks to the increasing investment of government agencies, private companies, and venture capitalists. From the beginning of the New Space era, the array of actors involved in the development of technologies for extra‐terrestrial activities has increased, as well as the downstream applications that foster ...

Similarity Assessment of the Engineering Concepts: Decision‐Making Support and Metrics

open access: yesSystems Engineering, EarlyView.
ABSTRACT The new product development (NPD) process is a systematic approach to bring new products and innovations to market. Nowadays, this process is affected by a number of influencing factors associated with the fast‐paced technological changes. One of those factors is the distributed design nature of product development activities: team members are

An Orbitrap-based laser desorption/ablation mass spectrometer designed for spaceflight [PDF]

open access: yes, 2018
RATIONALE: The investigation of cryogenic planetary environments as potential harbors for extant life and/or contemporary sites of organic synthesis represents an emerging focal point in planetary exploration. Next generation instruments need to be capable of unambiguously determining elemental and/or molecular stoichiometry via highly accurate mass ...
