Space Activity Regulatory Matters of Space Law

open access: yesAdvanced Space Law, 2020
This article studies the issues of international space law and analyses the reasons for its occurrence. At the moment, space law actively develops, and space exploration has become increasingly popular and demanded. Nevertheless, this field’s legal regulations were drawn up in the mid-20th century and are now partly obsolete. Moreover, the set of space-

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

A semi-empirical approach to simulating the Dst index in global MHD models of Earth’s magnetosphere

open access: yesEarth and Planetary Physics
The Dst index has been commonly used to measure the geomagnetic effectiveness of magnetic storm events for several decades. Based on Burton’s empirical Dst model and the global magneto-hydrodynamic (MHD) simulation of Earth’s magnetosphere, here we ...

Excitable Patterns in Active Nematics [PDF]

open access: yes, 2010
We analyze a model of mutually-propelled filaments suspended in a two-dimensional solvent. The system undergoes a mean-field isotropic-nematic transition for large enough filament concentrations and the nematic order parameter is allowed to vary in space

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
