A research team demonstrated that pulsed electric field (PEF) processing can effectively inactivate harmful foodborne bacteria in bovine colostrum while potentially preserving its valuable immune-supporting compounds. 

A recent study published in Protein & Cell by researchers from the Southern University of Science and Technology (SUSTech) provides critical structural and functional insights into the UBR4-KCMF1-Calmodulin (UKC) complex, revealing its pivotal role in protein quality control, cancer cell survival, and stress adaptation. The work, led by Professors Renhong Yan and Baotong Zhang, elucidates how this complex assembles and functions as an E4 ubiquitin ligase, extending ubiquitin chains on pre-tagged substrates to regulate protein degradation.

In a recent study published in Space: Science & Technology, a research team from Simon Fraser University and the University of Calgary, for the first time, adopted the brain vital signs framework to monitor cognitive and neurophysiological function in astronauts participating in a 17‑day mission to the International Space Station.

A research team has found that plant-derived biochar can help restore acidified tea plantation soils, with coconut shell biochar showing the strongest overall effect. 

A research team has developed an efficient, low-cost material designed to produce clean hydrogen gas from water. This research offers news perspectives and valuable insights into the development of efficient, stable, and economical noble metal-free electrocatalysts for green hydrogen production.

Current dithioester synthesis methods are cumbersome, inefficient and often toxic. A research team recently developed a green synthesis technique for dithioester generation using sulfide powder, alkyl bromides and aromatic aldehydes as precursor molecules in a photocatalysis reaction.

In recent years, rapidly advanced space technology has resulted in a growing number of objects in orbit, including both operational and decommissioned spacecraft, as well as space debris, which pose potential threats to China’s on-orbit spacecraft. To ensure the safe operation of spacecraft in near-Earth and high-orbit environments, a key research focus in the field of space technology is the high-resolution and high-accuracy detection and perception of environmental objects under strong backlight conditions. Such capabilities are critical for providing timely early warnings to on-orbit spacecraft. However, a plethora of studies have demonstrated marked challenges in imaging dark and weak targets under strong light backgrounds. It is essential to analyze the challenges of current backlight imaging technologies, summarize the working principles of existing backlight detection methods, and explore future development trends.
