Geometric calibration of all-sky auroral imager based on gradient descent method and the star maps
The all-sky imager is an important ground-based auroral observation equipment. Accurate optical geometric correspondence between "object-image" is the foundation for obtaining the structural scale of auroras and achieving joint observations between the all-sky imager and satellites. This paper…

Venus's atmospheric superrotation
Venus, the planet closest to Earth, has a slowly retrograde rotation in the opposite direction to Earth's, and it has a dense atmosphere that exhibits rapid westward motion. At the cloud top, around 65–70 km in altitude, zonal wind speeds reach up to 100 m/s—about 50–60 times faster than the…

Recent advances in the interior structure of the gas giants
Jupiter and Saturn, as the gas giants of our solar system, account for over 90% of the total mass beyond the Sun and hold most of the system's angular momentum, playing a crucial role in the early history of the solar system. During their formation, these planets captured vast amounts of material…

Review on research status and development trends of solar radio spectrometers
Intense solar activity is a major driver of hazardous space weather. The associated processes, including strong electromagnetic radiation, plasma ejections, and high-energy particle acceleration, can significantly disturb the Sun-Earth environment within a short time and further trigger a series of…

Progress in research on atmospheric vortices of gas giant planets
The atmospheres of gas giant planets contain multi-scale vortex structures, which are not only key components of planetary weather systems but also important windows for understanding their internal dynamics and thermodynamic processes. This paper reviews recent advances in the study of atmospheric…

Review of the lunar charged particle environment
Charged particles constitute one of the essential physical elements within the lunar space environment. Their origins, compositions and energy spectra are remarkably complex, and their spatial distribution and temporal dynamics are intricately coupled with localized electromagnetic field…

The role of modified electron acoustic waves in the evolution of quasi-static parallel electric fields
The auroral arc is a common form of aurora. Its formation involves three processes: the transfer of disturbed energy from the source region to the acceleration region via Alfvén waves, the generation of acceleration structures within the acceleration region, and the acceleration of electrons to…

Ribosome engineering enhances genetic code expansion in Saccharomyces cerevisiae
Genetic code expansion enables the site-specific installation of noncanonical amino acids (ncAAs) into proteins, but its limited efficiency in eukaryotes remains a major barrier to broader application. Here we establish a visual, plug-and-play screening platform to evolve 18S ribosomal DNA in…

Numerical investigation of reinforced concrete shear walls under bi-axial loading conditions
This study investigates the effects of bi-axial loading on the seismic performance of reinforced concrete (RC) shear walls through nonlinear finite element analysis (FEA). The analytical models were developed and validated against previously published experimental results, and direct comparisons…

Combined effects of Joule heating and nonlinear thermal radiation on stagnation-point flow of a second-order nanofluid over an exponentially stretching surface
This article examines the stagnation-point flow and thermal transmission of a second-order nanofluid over an exponentially stretching surface, incorporating Joule heating and a magnetically induced field. The mathematical model includes nonlinear thermal radiation, activation energy, zero mass…

On unprotected loss-of-flow accident in a generic molten-salt reactor
Unprotected loss-of-flow (ULOF) transients in molten salt reactors (MSRs) are governed by a unique interplay between thermal-hydraulics and neutronics due to the circulation of the fuel salt, which carries the delayed neutron precursors (DNPs). This study analyzes a generic fast-spectrum molten…

The rapid rise of ultra-processed foods brings up human health concerns
The global consumption of ultra-processed foods (UPFs) has surged in recent decades, driven by shifts in lifestyle, dietary patterns, and socioeconomic dynamics, with accelerated growth observed post-COVID-19 pandemic. Defined as industrially formulated ready-to-consume products, UPFs undergo…
