GeotechnicsIn the exploration missions for Mars and the Moon, rovers with legs as mobility mechanisms are necessitated owing to their high mobility. However, the surface of Mars and the Moon is loose, leading the rovers to slip by virtue of the ground easily ...

Experimental Physiology, EarlyView.Abstract Bed rest accelerates bone loss and may exacerbate skeletal fragility. This study examined the effects of 14 days of head‐down tilt bed rest (HDBR) with or without exercise, and subsequent recovery, on bone turnover, density and structure in older adults. Twenty‐two healthy older adults (55–65 years) completed the HDBR protocol.

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.Abstract Watersheds regulate biogeochemical processes and provide ecosystem services to human societies, but disturbances can fundamentally alter these processes across space and time. Determining when and where to sample to capture disturbance impacts in watersheds remains a central challenge.

Contemporary Management of Human‐Caused Hybridization in Mammals: A Review
Mammal Review, Volume 56, Issue 4, December 2026.By reviewing studies on human‐mediated (i.e., anthropogenic) hybridization, we identify key management gaps, including inconsistent identification of admixed individuals, limited population‐level assessments, insufficient social engagement, and unclear management objectives.

Defecation in preparation for ecdysis drives microplastic clearance in cricket nymphs
Physiological Entomology, Volume 51, Issue 4, Page 562-574, December 2026.In preparation for ecdysis, cricket nymphs cease feeding and gradually clear their gut contents via frass production, which removes most ingested MPs from their digestive tract. Following exoskeletal moulting, the foregut lining, including any remaining MPs, is shed and excreted alongside frass approximately 6 h later.

Convective Vertical Velocities of Dust Devils in Gale Crater, Mars
Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.Abstract Dust devils are believed to be a significant contributor to the martian global dust cycle, supplying as much as 50% of dust to the atmosphere annually. However, their in situ meteorological properties remain poorly known, specifically horizontal and vertical wind speeds.

A Modular Avionics Architecture for a Planetary Rover Demonstrator for Human Assistance [PDF]
Current planetary rovers are designed with mission-specific monolithic architectures, limiting flexibility and increasing costs. As the space economy grows, more infrastructure will be needed on the Moon and Mars, including numerous rovers for human ...
