Compliant Robotics in Space: A Prospective Review of Soft and Deformable Systems for Space Missions
Advanced Intelligent Systems, Volume 7, Issue 7, July 2025.Compliant robots are increasingly becoming integral to space exploration due to their adaptability, flexibility, and lightweight design. This article reviews categories such as soft, reconfigurable, and hyper‐redundant robots and their evolving role in enhancing space missions.

Aging Cell, Volume 24, Issue 7, July 2025.Transcriptomic analyses reveal an age‐related decline in autophagy pathways in RPE/choroid. These pathways remain unchanged in early AMD but become bidirectionally dysregulated in later stages, along with increased RPE loss. Pre‐treatment with trehalose eyedrops enhances RPE autophagy flux and prevents light‐induced outer retinal degeneration in mice ...

Radial migration in disc galaxies — I. Transient spiral structure and dynamics [PDF]
, 2011 We seek to understand the origin of radial migration in spiral galaxies by analysing in detail the structure and evolution of an idealized, isolated galactic disc.

Revisiting the Integrated Star Formation Law. I. Non-starbursting Galaxies [PDF]
Astrophysical Journal, 2019 We use new and updated gas- and dust-corrected star formation rate (SFR) surface densities to revisit the integrated star formation law for local “quiescent” spiral, dwarf, and low surface brightness galaxies. Using UV-based SFRs with individual IR-based

Plasticity of the heart in response to changes in physical activity
The Journal of Physiology, Volume 603, Issue 13, Page 3665-3677, 1 July 2025.Abstract figure legend The heart adapts to changes in physical activity, with inactivity (e.g. bed rest or spaceflight) causing cardiac atrophy and ventricular stiffening, and endurance exercise training leading to eccentric hypertrophy and improved ventricular compliance.

H II regions and the abundance properties of spiral galaxies
, 1994 We investigate the relationships between the characteristic oxygen abundance, the radial abundance gradient, and the macroscopic properties of spiral galaxies by examining the properties of individual H II regions within those galaxies.

OBSERVATIONAL EVIDENCE AGAINST LONG-LIVED SPIRAL ARMS IN GALAXIES [PDF]
, 2011 We test whether the spiral patterns apparent in many large disk galaxies should be thought of as dynamical features that are stationary in a corotating frame for ≳ tdyn, as implied by the density wave approach for explaining spiral arms.

Advanced Electronic Materials, Volume 11, Issue 9, June 2025.This paper provides a comprehensive review of the existing literature related to the fundamentals of gallium oxide (Ga2O3), growth methods, substrates, and particularly a focused examination of Ga2O3‐based heterojunctions. Particular attention has also been given to the state‐of‐the‐art Ga2O3‐based heterojunctions for photodetectors. The key challenges
