Detections of Water Vapor Increase Over the North Polar Troughs on Mars as Observed by CRISM
Geophysical Research Letters, 2020 The Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) onboard the Mars Reconnaissance Orbiter has been observing the north polar layered deposits (NPLD) of Mars. Polar wind circulations are instrumental in shaping the NPLD.

In situ synthesis of high dielectric constant GNPs/PBO nanocomposites with enhanced thermostability
IET Nanodielectrics, 2019 Graphite nanoparticles (GNPs) were introduced into poly(p-phenylene benzobisoxazole) (PBO) matrix to produce composites via in situ polymerisation. Films of various composites were fabricated through the solution casting method in methanesulfonic acid ...

Root Skewing-Associated Genes Impact the Spaceflight Response of Arabidopsis thaliana
Frontiers in Plant Science, 2020 The observation that plant roots skew in microgravity recently refuted the long-held conviction that skewing was a gravity-dependent phenomenon. Further, spaceflight root skewing suggests that specific root morphologies and cell wall remodeling systems ...

Genetic dissection of the Arabidopsis spaceflight transcriptome: Are some responses dispensable for the physiological adaptation of plants to spaceflight? [PDF]
PLoS ONE, 2017 Experimentation on the International Space Station has reached the stage where repeated and nuanced transcriptome studies are beginning to illuminate the structural and metabolic differences between plants grown in space compared to plants on the Earth ...

Alterations in Saliva and Plasma Cytokine Concentrations During Long-Duration Spaceflight
Frontiers in Immunology, 2021 Long-duration spaceflight is known to cause immune dysregulation in astronauts. Biomarkers of immune system function are needed to determine both the need for and effectiveness of potential immune countermeasures for astronauts.

An Observation‐Driven Approach to Improve Vegetation Phenology in a Global Land Surface Model
Journal of Advances in Modeling Earth Systems, 2020 An empirical model calibration approach is presented that aims to approximate missing biosphere processes in a global land surface model without the need for substantial model structural changes.
