Utilizing high-resolution occultation data from China’s Tianwen-1 probe, key parameters of internal gravity waves in the Martian atmosphere—such as vertical wavelength, frequency, and energy density—have been extracted for the first time. These findings are further compared with occultation data obtained from the Mars Global Surveyor (MGS), providing a more profound analysis of internal gravity wave characteristics across different datasets. Earth and Planetary Physics (English) recently reported these results.

A significant space weather phenomenon that has attracted much interest from the scientific community, industry, and the general public is geomagnetic storms. In May 2024, a powerful geomagnetic storm occurred, causing substantial changes in Earth upper atmosphere. A research team from the Institute of Geology and Geophysics, Chinese Academy of Sciences, carried out a comprehensive investigation to look into how this superstorm affected different regions of the upper atmosphere. They utilized multiple ground-based and satellite observation instruments to examine the response of the ionosphere-thermosphere coupling system. Earth and Planetary Physics has published the study's results.

In a paper published on aBIOTECH, the authors generated non-transgenic tobacco mutants with ultra-low nicotine levels by knocking out BBL gene family members using CRISPR/Cas9 nuclease delivered by an engineered RNA virus vector.

In a paper published on aBIOTECH, the authors developed a pipeline to identify, characterize and edit the CRE, and further manipulate the expression pattern of gene as well as the resulting phenotypes.

The in vitro antioxidant assay showed that the four sea buckthorn polysaccharides (SP, SPA, SPB, and SPC) were good at getting rid of superoxide anion and DPPH radicals, especially ABTS radicals. They were also better at getting rid of free radicals than VC at low concentrations, and they were also good at reducing other molecules. Therefore, sea buckthorn polysaccharide can be used as a natural antioxidant with great potential as a functional cosmetic ingredient.

A research team from Zhejiang University has developed a strong and tough CoNiCr alloy by overcoming intermediate temperature brittleness (ITB). By using the strategy of grain boundary engineering (GBE), the strength and ductility of the alloy are simultaneously improved at elevated temperature. The solution here might provide a pathway to overcome the GB brittleness, which currently restricts practical application of many metallic alloys.
