Global Distribution and Seasonality of Martian Atmospheric HCl Explained Through Heterogeneous Chemistry

open access: yesGeophysical Research Letters
Recent observations from the ExoMars Trace Gas Orbiter (TGO) have revealed the presence of hydrogen chloride (HCl) in the martian atmosphere. HCl shows strong seasonality, primarily appearing during Mars' perihelion period before decreasing faster than ...

Effect of Housing Layout and Open Space Morphology on Residential Environments–Applying New Density Indices for Evaluation of Residential Areas Case Study: Tehran, Iran

open access: yesJournal of Asian Architecture and Building Engineering, 2018
Over time, urban developments with increased densities have led to a decrease in private open space with a lack of public open space. Residential open spaces are missing in housing legislations as they are estimated based on floor area ratio and building

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

The viscosity and processing of molten lunar regolith

open access: yesScientific Reports
Establishing a permanent, self-sufficient habitat for humans on planetary bodies is critical for successful space exploration. In-situ resource utilisation (ISRU) of locally available resources offers the possibility of an energy-efficient and cost ...

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

A primordial noble gas component discovered in the Ryugu asteroid and its implications

open access: yesNature Communications
Ryugu is the C-type asteroid from which material was brought to Earth by the Hayabusa2 mission. A number of individual grains and fine-grained samples analysed so far for noble gases have indicated that solar wind and planetary (known as P1) noble gases ...

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Strategies to Improve Sustainability in Urban Landscape, Literature Review

open access: yesJournal of Landscape Ecology, 2016
Decreasing green spaces is a significant concern in today’s compact cities while they provide various dimensions of sustainability; therefore, sustainable development has become the key idea to solve a series of environmental, economic and social ...

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Underlying relational dimensions of flow transitions along ring roads and their impacts on the typo-morphology of open spaces: two cases from Nordic countries

open access: yesUrban, Planning and Transport Research, 2021
This study explores the roles and functions of urban voids and their relationship with the built forms alongside ring roads. This investigation sheds light on the typo-morphology of open spaces in regard to the flow transitions (in substance, intensity ...
