Graph Theory and Network Structure: From Map Colouring to Social Connectivity
Social media followers, connective routes across a country, and electrical grids/electrical networks all have a commonality; they form relationships with solutions based in graph theory. Graph theory is the study of graphs and their properties, where a graph is defined as an ordered pair (V, E). V refers to the set of vertices (nodes) and…

Primary Blast Waves: Brain Injury Without Direct Head Impact?
Following an explosion, brain injury does not just come from direct impact to the head, but instead can start from just the exposure to the blast. Primary blast injury is the direct result of an overpressure wave (Xu et al. 2016). It can arise despite there being no visible head contact or trauma. It is…

Sediments and Substances: GC-MS Analysis in Geochemistry
Technological developments have allowed us to uncover the identities of mystery substances with increasing accuracy. From applications in forensic research to artifact analysis, gas chromatography-mass spectrometry (GC-MS) combines two methods used in modern analytical chemistry to provide an effective means of identifying chemicals. GC-MS is an analytical technique often used to identify and measure the…

A Glass of Wine a Day Keeps the Atherosclerosis Away?
The idea that wine is good for the heart sounds too good to be true, and scientifically, it might be. As of 2022, cardiovascular disease was the second leading cause of death in Canada, just after cancer (Public Health Agency of Canada 2017). The build-up of plaque inside arteries, or atherosclerosis, is a main underlying…

Smogging Up the Mind
What if the haze clouding your thoughts was not just metaphorical, but a literal consequence of air pollution? Pollution and climate change have been prevalent issues in recent years, casting a shadow over health and well-being. Epidemiological research has indicated neurological effects on the central nervous system (CNS) from ambient air pollution (Xu, Ha, and…
