Limited musculoskeletal benefits of artificial gravity combined with cycling during bed rest: Results from the BRACE study

open access: yesExperimental Physiology, EarlyView.
Abstract Prolonged exposure to microgravity, simulated via 6° head‐down tilt bed rest (HDT), induces musculoskeletal deconditioning and negatively impacts body composition. This study evaluated whether a combination of aerobic exercise with artificial gravity (AG) offers superior protection in comparison to exercise alone.

Geoeffectiveness and efficiency of CIR, Sheath and ICME in generation of magnetic storms

open access: yes, 2011
We investigate relative role of various types of solar wind streams in generation of magnetic storms. On the basis of the OMNI data of interplanetary measurements for the period of 1976-2000 we analyze 798 geomagnetic storms with Dst < -50 nT and their ...

Blockchain for the Arts and Humanities

open access: yesFuture Humanities, Volume 4, Issue 1, May 2026.
ABSTRACT As born‐digital cultural materials proliferate, the arts and humanities require infrastructures that guarantee provenance, authenticity, and equitable access. This paper delivers a comprehensive, critical survey of blockchain's potential and limits across the sector.

Unique Observations of a Geomagnetic SI^+ -- SI^- Pair: Solar Sources and Associated Solar Wind Fluctuations

open access: yes, 2010
The paper describes the occurrence of a pair of oppositely directed sudden impulses (SI), in the geomagnetic field ($\Delta$X), at ground stations, called SI${^{+}}$ -- SI${^{-}}$ pairs, that occurred between 1835 UT and 2300 UT on 23 April 1998. The SI${

Surface‐Driven Protocell Formation in Geologically Relevant Early Earth Environment

open access: yesChemSystemsChem, Volume 8, Issue 2, March 2026.
Illustration of a prebiotic early‐Earth environment showing cell‐like protocells (blue spheres) and other complex organic molecules (pink and green spheres) distributed across terrestrial surfaces and within subsurface niches. Volcanic landscapes and mineral‐rich substrates provide diverse geochemical settings for the assembly and evolution of ...

Effects of standard and modified gravity on interplanetary ranges

open access: yes, 2011
We numerically investigate the impact on the two-body range by several Newtonian and non-Newtonian dynamical effects for some Earth-planet (Mercury, Venus, Mars, Jupiter, Saturn) pairs in view of the expected cm-level accuracy in some future planned or ...

CMEs evolve in the interplanetary medium to double their predicted geo-effectiveness

open access: yesAstronomy & Astrophysics
We explore the impact of interactions between coronal mass ejections (CMEs) ---known as CME--CME interactions--- on Earth using remote-sensing and in situ observations and estimate the amplification of the geo-effectiveness of the individual CMEs by a ...

African Decolonial Theory: A Conversation

open access: yesAntipode, Volume 58, Issue 2, 2026.
Abstract Antipode has become a key platform for engaging with decolonial and anticolonial scholarship, as well as adjacent fields such as Black geographies, Indigenous studies, Latin American feminism, and work on settler‐colonialism. African reference points in this literature, however, have been far less common, both in the journal and more broadly ...

Observations of an extreme storm in interplanetary space caused by successive coronal mass ejections

open access: yes, 2014
Space weather refers to dynamic conditions on the Sun and in the space environment of the Earth, which are often driven by solar eruptions and their subsequent interplanetary disturbances.
