Highlights: Pre- and post-tests, administered to 2,141 emergency first responder participants, showed an average improvement in test scores from 67% to 75%, highlighting the efficacy of the training. Interviews conducted within 3 years post-training revealed high participant satisfaction, with over 25% reporting adoption of key strategies discussed in the training by their fire/rescue service. Areas of concern were identified, including the lack of understanding related to certain hazards, such as free-flowing grain, which may put first responders at risk of secondary victimization.

Materials for extreme-condition thermal insulation need to simultaneously withstand complex thermomechanical stresses while retaining their insulating properties at high temperatures. Ceramic aerogels are attractive candidates, but conventional low-entropy ceramics usually suffer from formidable grain growth with severe volume shrinkage and strength degradation, resulting in catastrophic failures. Herein, a high-entropy (LaSmGdY)ZrO (ZLSGY) aerogel is made through an element-phase design, realizing enhanced lattice distortion and sluggish diffusion effects to achieve fine-grain strengthening under extreme conditions.

In the context of nuclear emergency preparedness, the level of radiation knowledge among healthcare professionals-such as doctors, nurses, and radiographers-directly influences the effectiveness and safety of emergency responses. This study aims to address this gap by evaluating the radiation knowledge of medical personnel and identifying areas for improvement in profession-specific training programs.

() are a gene family that relies on NAD +/NADP + proteins to oxidize toxic aldehydes to non-toxic carboxylic acids, and they play a crucial role in the growth and development of plants, as well as in their ability to withstand stress. This study identified 26 genes from six gene families distributed on six chromosomes. By analyzing the phylogeny, gene structure, conserved motifs, cis-regulatory elements, collinearity of homologs, evolutionary patterns, differentiation patterns, and expression variations under drought stress, we found that the gene is involved in phytohormones and exhibits responsiveness to various environmental stressors by modulating multiple cis-regulatory elements.
