Teaching graduate students the entanglements of the interdisciplinary field of electrochemical DNA biosensors in microfluidics can be challenging, as it involves multiple fields of research strongly interacting with each other. Yet, electrochemical biosensors coupled with the improved hydrodynamics of microfluidics allow for simpler, more…

Green chemistry is finding its place as one of the most essential study topics in the curriculum of future chemists and chemical engineers. Experiments that meet green chemistry principles contribute to make the laboratory a safer working place, generate less waste, and allow students to increase their knowledge in new environmentally friendly…

Both nanopore-based DNA sequencing and CRISPR/Cas-based gene editing represent groundbreaking innovations in molecular biology and genomics, offering unprecedented insights into and tools for working with genetic information. For students, reading, editing, and even writing DNA will be part of their everyday life. We have developed a laboratory…

The understanding of the basic principles of chromatography is of high importance for chemistry, pharmacy, and biology students. In this paper, we present a free web application which can be used as a teaching tool to introduce chromatography to undergraduate students, using one of the simplest chromatography models: the plate theory.

Increasingly, science teachers are seeking phenomena that will allow them to explore both scientific content and socially relevant issues. The authors describe a series of lessons that (1) model the exoneration of wrongly convicted individuals using the science of DNA analysis and (2) contextualize individual cases within a larger system where…

Single-crystal X-ray structures, melting points, and students' specific rotation results on carvone semicarbazone derivatives are presented with experimental details. Critical parameters are identified to ensure the success of the experiment. Procedures developed here were tested in a laboratory course, consisting of approximately 70 students over…

The remarkable variation in superficial veins of the neck challenges anatomy students during cadaveric exploration. Despite frequently serving as cannulation sites, conduits for catheter placement, grafts following carotid endarterectomy, and a visual representation of central venous pressure, the jugular venous network and its variations are not…

Nitrate is a crucial parameter for assessing water quality, owing to its dual function in ecological systems. These functions can be beneficial or detrimental depending on whether nitrate concentrations are low or high, respectively. The ultraviolet spectrophotometric method (standard as 4500-NO[subscript 3]--B) is a classic method for determining…

Hands-on dissection-based learning of anatomy offers an unique and valued experience for medical students. Too often however, the inexperienced student's focus is to avoid damage to unfamiliar structures instead of understanding spatial relationships between structures. This results in unfortunate surrender of a critical learning experience.…

A multioutcome, guided inquiry-based liquid--liquid extraction (LLE) experiment has been designed for introductory organic chemistry. Multiple outcomes were established by identifying a series of red and blue dyes that are (1) soluble in organic solvent, (2) soluble in aqueous solution, or (3) soluble in either the organic or aqueous layers by…

The laboratory practice "Primary culture and directional differentiation of rat bone marrow mesenchymal stem cells (BMSCs)" is part of a required course for sophomore medical students at Tongji university, which has been conducted since 2012. Blended learning has been widely applied in medical courses. Based on a student-centered…

Laboratory courses should cultivate enthusiasm for research and an appreciation for real-world scientific challenges to retain undergraduate students and encourage them to pursue STEM-related careers. Course-based undergraduate research experiences (CURE) have emerged as an inclusive pedagogical model that facilitates laboratory skill development,…

A lab activity for teaching physics students the fundamentals of statistical analysis during the first few weeks of instruction is described. This activity involves students timing a pulse of light generated by an Arduino device of fixed duration with individual timers (e.g. stopwatch, iPhone timer). To select the most precise timing methods and…

Traditional developmental biology laboratory classes have utilized a number of different model organisms to allow students to be exposed to diverse biological phenomena in developing organisms. This traditional approach has mainly focused on the diverse morphological and anatomical descriptions of the developing organisms. However, modern…

The core values in medical practice which are essential for the humane outlook of a physician are clubbed within the domain of medical professionalism. Professionalism along with other discipline-independent skills (human skills) is propagated implicitly in medical schools as components of a "hidden curriculum." Evidence suggests a…
