Horses Can Integrate Senses to Detect Human Emotion

Caleb Sooknanan ‘20 Horses can cross-modally, or with multiple senses simultaneously, distinguish human facial expressions and recognize people with whom they are acquainted. While horses may be able to cross-modally distinguish human emotions, more research is needed to understand these animals’ cognitive abilities. Doctor Toshizaku Hasegawa and researchers from Hokkaido University in Japan conducted a…

Using Microelectrode Arrays on Soft Substances

Caleb Sooknanan ‘20 Microelectrode arrays or MEAs are electrode systems that can be used to analyze electric signals among cardiac cells and neuronal cells, repair sensory abilities among human patients, and address nervous system disorders. However, most of the devices currently associated with MEAs rely on silicon or polymer substances, which make it difficult for…

The Effects of the Gut on Fruit Flies’ Lifespans

By Caleb Sooknanan ‘20 Aging and chronic diseases are often associated with effects such as metabolic and oxidative stresses, inflammation, and mitochondrial deficiencies. Scientists have suggested that changes in organisms’ gut microbiota relate to specific gut phenotypes, while probiotics can be ingested to regulate chronic disease progression in conjunction with microbiota changes. However, more research…

Electric Fields Can Recover Fresh Water from Fog

By Caleb Sooknanan ‘20 Over 1 billion people lack access to safe drinking water worldwide, and for many coastal regions with little or no rain and expensive water transportation measures, water only appears in dense fog layers. Fog collection or fog harvesting techniques have become useful for extracting water from these regions, with some systems…

The Use of Sugar Glass Scaffolds for 3D Printing

By Caleb Sooknanan ‘20 Three-dimensional (3D) printing — a form of additive manufacturing — involves the joining and solidification of material to create objects from computer files. Glasses made of sugars or carbohydrates have become practical materials for printing more complex structures, such as organs, because of their stiffness and durability. These sugar glass materials…
