Mastering the complexity of the nervous system is essential for education programs in physiology, anatomy, and neuroscience. Students often struggle when learning somatosensory pathways, which convey information from sensory neurons to the somatosensory cortex in the brain. Active learning activities incorporating physical models have been shown…

The urea cycle disorder drug glycerol phenylbutyrate (Ravicti) is presently one of the most expensive medications in the United States, with annual costs estimated at $800,000 as of 2023. An expedient synthesis of this orphan drug was successfully adapted for the undergraduate organic chemistry laboratory. Activation of 4-phenylbutyric acid with…

In undergraduate life sciences education, open educational resources (OERs) increase accessibility and retention for students, reduce costs, and save instructors time and effort. Despite increasing awareness and utilization of these resources, OERs are not centrally located, and many undergraduate instructors describe challenges in locating…

Liquid metals are widely applied in various fields, including chemistry, catalysis, energy storage, chemical sensing, and stretchable electronics, due to their unique deformabilities. However, their behavior under a rod or ring electrode has never been analyzed. Furthermore, research on the deformation behavior of eutectic Ga--In (EGaIn), the most…

Anaerobic respiration reactions are of fundamental importance to global biogeochemical cycling of elements. Yet, the idea that cellular respiration can occur not only in the absence of oxygen but also involve the oxidation of inorganic substrates (e.g., AsO[subscript 3 superscript 3-], Fe[superscript 2+], H[subscript 2], H[subscript 2]S,…

The variation in the transference number of H[superscript +] (aq) is investigated for different HCl solution concentrations. The method for scribing graduations on electromigration tubes is modified to decrease the error in experimental measurements, and metallic copper is used as the anode to reduce the toxicity and environmental impact of the…

A multicomponent reaction was adapted and successfully applied in the major organic course, which involves synthesizing and characterizing a 1,3-benzoxazine derived from paracetamol extracted from tablets of the worldwide well-known medicine Tylenol. Using paracetamol as a reagent is a motivational strategy in undergraduate laboratories to meet…

A mixture of salt water and isopropyl alcohol is immiscible, forming two separate liquids with the organic layer on top and aqueous layer on bottom. When universal indicator is added to such a mixture, all of the indicator compounds in the universal indicator preferentially dissolve in the alcohol--except for phenolphthalein at high pH. Mixtures…

Studies document difficulties undergraduate pre-nursing and allied health students face when learning human anatomy and physiology (A&P) course content. A comprehensive synthesis exploring the teaching practices within the course and how those practices are evaluated is warranted. This scoping literature review identified 78 journal articles…

A new undergraduate thin-layer chromatography laboratory experiment devoted to quantitative determination of disulfiram in Anticol formulation is presented. The proposed activity can be a part of a chromatographic methods of analysis course as well as a general chemistry course. To carry out a quantitative analysis, an image analysis technique was…

The purpose of this study was to assess and describe the status of program evaluation within the National Science Foundation's (NSF) Research Experiences for Undergraduates (REU) sites. The National Science Foundation's REU program supports thousands of undergraduates annually in hands-on, immersive research experiences under the mentorship of…

Purpose: This study aims to explore the impact of engaging in serious leisure (SL) on the well-being (WB) and self-perceived employability (PE) of university students while also considering the role of career adaptability (CA) as a mediator. Design/methodology/approach: A total of 905 domestic undergraduate students from China completed an online…

An undergraduate laboratory experiment has been developed for the synthesis of a reactive cross-linker that is useful in various highly visual demonstrations of organic reactivity, click chemistry, and biobased polymer synthesis. A triazolinedione-based cross-linker, which is known as a useful reagent for click chemistry, can be obtained from…

In analytical chemistry, discussing different method sand techniques of analysis is essential to promote critical thinking and reasoning. Analytical courses in the chemist, pharmacist, and biochemist curricula represent the opportunity to study concepts such as experimental design, sampling, development, and optimization of protocols, data…

This paper presents two low-cost hands-on activities designed to enhance student understanding and address the pedagogical challenges faced by microbiology professors in teaching concepts related to cell structure and gene regulation. In the first activity, we used Shrinky Dinks and Jeopardy-style game questions to explore the differences between…
