Temperature and nutrients are known as crucial drivers for the variations of bacterial community structure and functions in oceans and lakes. However, their significance and mechanisms in influencing the bacterial community structure and function in mountain stream remain unclear. In this study, we investigated the spatiotemporal patterns of the bacterial communities and the main environmental factors in the Taizicheng River, a high-latitude mountainous stream, to reveal the main driving factors for sedimental bacterial communities.

Marine invasive species pose significant ecological, economic, and social challenges, disrupting native ecosystems, outcompeting local species and altering biodiversity. The spread of these species is largely driven by global trade, shipping, and climate change, which allow non-native species to establish themselves in new environments. Current management strategies, including early detection, rapid response, and biosecurity measures, have had some success, but the complexity and scale of the problem require continuous monitoring.

Introduction: A physician's first patient harm event oftentimes occurs during the intern year. Residents encounter and are responsible for medical errors, yet little training is offered in how to properly cope with these events. Earlier and more in-depth education about how to process patient harm events is needed.

Background: Traumatic brain injury (TBI) management guidelines vary across regions and there is limited research on real-world adherence to these guidelines. We conducted a global survey to assess the adherence of neurosurgeons to TBI guidelines and evidence-based medicine (EBM).
Method: A 24-item survey was created using Google Forms, covering demographic information, neurotrauma training, basic knowledge of EBM, surgical and in-hospital management.

Article Synopsis
- There is growing interest in using psychedelics like psilocybin to treat hard-to-manage psychiatric disorders, but little is known about how the experiences they create affect mood afterward.
- In experiments with mice, it was found that psilocybin increased head-twitch responses more in females than in males, highlighting a sex difference in its effects.
- Stress exposure during or after taking psilocybin impacted anxiety-like behavior in males, blocking its calming effects, while females only experienced a partial effect, suggesting that both sex and the context of the experience are important in understanding the drug's impact.
