Individual variability in activity patterns in Atlantic halibut (Hippoglossus hippoglossus) revealed using pop‐up satellite tags

open access: yesJournal of Fish Biology, EarlyView.
Abstract Understanding fish behaviour and activity patterns is essential for interpreting their ecology and the processes that shape population dynamics, yet such information remains limited for wild fishes because observing individuals in situ is challenging.

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Tethered subsatellite study [PDF]

open access: yes
The results are presented of studies performed relating to the feasibility of deploying a subsatellite from the shuttle by means of a tether. The dynamics, the control laws, the aerodynamics, the heating, and some communication considerations of the ...

Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.

Satellite relocation by tether deployment [PDF]

open access: yes
Several new uses of satellite tethers are discussed, including: (1) using tether extension to reposition a satellite in orbit without fuel expenditure by extending a mass on the end of a tether; (2) using a tether for energy storage to power the ...

The rise of the ecocentric right to a healthy environment before human rights courts in Africa and Latin America

open access: yesReview of European, Comparative &International Environmental Law, EarlyView.
Abstract This article examines jurisprudence from key African and Latin American human rights bodies regarding the right to a healthy environment, with a focus on recent jurisprudence (2023–2025). It identifies a growing trend of an ecocentric interpretation of the right, which acknowledges that the environment and the life forms within it hold ...

Reading Australia in a grain of rice

open access: yesThe Australian Journal of Anthropology, EarlyView.
Abstract By ethnographically reading Australia in a grain of rice, this article recasts Australia's entangled histories with the Asia‐Pacific and the epistemic tensions through which rice emerges as a source of sustenance and metabolic concern in everyday life.

Impact of tether cutting on onboard navigation during the Tethered Satellite Mission-1 [PDF]

open access: yes
The first Tethered Satellite System mission (TSS-1) is manifested for Shuttle Flight STS-44 in January of 1991. The TSS mission presents a new challenge to engineers, requiring advanced guidance, navigation and control concepts. Current NASA flight rules

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...
