Venous and Arterial Responses to Partial Gravity
Frontiers in Physiology, 2020 Introduction: Chronic exposure to the weightlessness-induced cephalad fluid shift is hypothesized to be a primary contributor to the development of spaceflight-associated neuro-ocular syndrome (SANS) and may be associated with an increased risk of venous

Lipid Signalling in Human Immune Response and Bone Remodelling under Microgravity
Applied Sciences, 2020 Since the first Apollo mission in 1969, microgravity has been linked to many alterations of astronauts’ physiology, among which immunosuppression, altered inflammation and bone loss represent relevant examples.

Reveal Non‐Uniform Passivation on Lithium Metal Anode With Operando Spectroscopic Ellipsometry
Advanced Energy Materials, EarlyView.In‐operando spectroscopic ellipsometry reveals how nucleation and crystallographic orientation govern the non‐uniform growth of native passivation films on lithium metal. Time‐resolved thickness mapping captures island formation and coalescence, while orientation‐dependent measurements show that the equilibrium film on Li(110) is approximately half as ...

Spatial Updating Depends on Gravity
Frontiers in Neural Circuits, 2020 As we move through an environment the positions of surrounding objects relative to our body constantly change. Maintaining orientation requires spatial updating, the continuous monitoring of self-motion cues to update external locations.

Multirobot Aerial Soft Manipulator for Floating Litter Collection
Advanced Intelligent Systems, EarlyView.A multirobot aerial manipulator enables autonomous floating litter collection by controlling the shape of a flexible rope equipped with a hook‐based tool. Adaptive rope‐shape planning enhances grasping performance while reducing tension, demonstrating the potential of aerial robots for floating litter removal. Removing floating litter from water bodies
