Global warming accelerates glacier melting, which releases antibiotic resistance genes (ARGs) into downstream ecosystems, poses a threat to ecological security and human health. Revealing the distribution and potential risks of ARGs in glaciers is crucial for assessing the impact of glacier melting caused by climate change on downstream ecosystems. Based on the above background, a research team of the Center for Pan-third Pole Environment of Lanzhou University published “Profiles and risk assessment of antibiotic resistome between Qinghai-Xizang Plateau and Polar Regions”.

Perfluoroalkyl substances (PFASs) refer to a group of man-made chemicals that are widely used due to their water- and stain-resistant properties and exceptional chemical stability. However, they often accumulate in the environment, causing environmental and health hazards. A team of researchers has recently shown how zinc oxide nanocrystals capped with specific ligands can efficiently defluorinate perfluorooctanesulfonic acid, a well-known perfluoroalkyl substance. This approach could solve PFAS recycling challenges.

The dental pulp is susceptible to microbial infection, which often results in inflammation, necrosis, and defects in the pulp-dentin complex. Traditional treatment strategies suffer from multiple limitations and do not promote neural regeneration. In a new International Journal of Oral Science study, researchers have now developed an injectable composite hydrogel containing bioceramics and gelatin methacrylate matrix with photo-crosslinking properties that promote neural differentiation and odontogenesis, opening doors to a new strategy for pulp-dentin complex repair.

Self-harm among adolescents has become a serious public issue. Among various risk factors, parenting styles have been shown to have a significant impact. However, few studies have explored how exactly different parenting styles influence self-harm behavior. In a new study, researchers identified different parenting styles perceived by adolescent’s and clarified their link to self-harm behavior. The findings suggest that positive parenting can act as a protective shield against self-harm behavior, guiding practical intervention strategies.
