Dry ice is widely used in the chemistry research settings as an excellent coolant. Herein, we report a case study of a graduate student researcher who lost consciousness while retrieving 180 lbs of dry ice from a deep dry ice container. We share the details of the incident and the lessons learned from it to promote safer handling of dry ice in these situations.

Dry ice is one of the world's most in-demand commodities for cold-chain distribution of temperature-sensitive products. It offers an effective cooling solution without requiring mechanical refrigeration or specialized equipment. Dry ice is commonly produced as pellets and blocks.

The fish intestine is a complex ecosystem where microbial communities are dynamic and influenced by various factors. Preservation conditions during field collection can introduce biases affecting the microbiota amplified during sequencing. Therefore, establishing effective, standardized methods for sampling fish intestinal microbiota is crucial.

Pro-biogenic is a recent terminology widely used for products that combine biogenic materials and probiotics which has made progressive improvement in a new era of research on functional foods. This study aimed to develop functional ice cream with and propolis extract (PE) as a biogenic part to develop ice cream's physiochemical and antioxidant characteristics. Five probiotic ice cream samples were prepared using different levels of PE powder (0%, 0.

Wetland macrophytes play a critical role in the performance of treatment wetlands (TWs), primarily through nutrient uptake. However, this retention is temporary, as nutrients are released back into the water upon the decomposition of plant litter. The removal of stored nutrients from TWs can be efficiently achieved by harvesting plants during the peak of the growing season, albeit with significant ecological disturbance.

Background: Gene expression is a fundamental process for plants to express their phenotype, and its analysis is the basis of molecular studies. However, the instability of RNA often poses an obstacle to analyzing plants grown in fields or remote locations where the availability of liquid nitrogen or dry ice is limited. To deepen our understanding of plant phenotypes and tolerance to field-specific stresses, it is crucial to develop methodologies to maintain plant RNA intact and safely transfer it for downstream analyses such as qPCR and RNA-seq.
