Sunscreen Project: Infographics and Children’s Book

Hi all! Throughout this school semester, I worked to address the racial misconception surrounding sunscreen use and melanoma prevention by spreading infographics around my campus, Northfield Mount Hermon School, and holding exhibitions and presentations on my children's book for universal sunscreen use. I wanted to share this with you all as well, so please check out some of the infographics and storyboards I worked on below! My research has…

Interested in DNA-Based Data Storage?

What is DNA-based Data Storage? As technology advances, data storage methods are becoming more diverse to suit the changing world and its needs better. Conventionally, data is stored in numerous storage centers, which are around 100,000 square feet large on average. However, a novel method of storing data in DNA is being developed, bringing a variety of new benefits and possibilities. As the name suggests, DNA-based data storage is…

How does Nicotine Addiction Work on Neurons?

Nicotine, which is an agonist—a substance that can mimic another, mimics acetylcholine by binding to neuronal nicotinic acetylcholine receptors (nAChRs), which are ligand-gated ion channels constructed from various subunits (Benowitz, 2010). As nicotine binds to the receptor, it generally causes depolarization of the neuron, allowing calcium and sodium to rush through the channels, and will act directly on the presynaptic terminal to release certain neurotransmitters — the catecholamines (Benowitz,…

Constrained Optimization in COVID-19 Vaccine Allocation [Part II]

In order to estimate the number of susceptible individuals in each county i, we need to consider the population size Ni and the total current COVID-19 cases Ci. Considering these factors, the estimate is given by : Ni − Ci    The Ni of the 14 Massachusetts counties ranges from 11,801 of Nantucket County to 1,618,160 of Middlesex County as of 2021. Ci is determined by data from the Massachusetts…

Cell Signaling: Enzyme-Linked Receptors

Introduction In the human body, hormones such as insulin and growth hormones interact with cells by enzyme-linked receptors to induce a process inside the cell. An enzyme-linked receptor is a transmembrane protein that responds to signals using an extracellular ligand-binding domain that is linked to a cytoplasmic enzymatic catalytic activity site (Dowd, F. J., & Abel, P. W. (2017). Pharmacodynamics. Pharmacology and Therapeutics for Dentistry, 2–14. https://doi.org/10.1016/b978-0-323-39307-2.00001-1). This means…

The Impact of Connecticut River’s Hydroelectric Facilities on Local Ecolife

Connecticut River https://en.wikipedia.org/wiki/Connecticut_River The Connecticut River has been serving as a major source of Hydroelectric energy for local regions in the states of Massachusetts and Connecticut since the 20th century. In late 2012, many facilities producing energy within the Connecticut River began the process of reliscencing, where they take in the concerns and thoughts of the general public and apply them through a refurbished contract about their uses with…

Cell Signaling – Ligand-Gated Ion Channel Receptors

In the last article we looked at G-protein coupled receptors. Now, we will be going over the another main type of cell receptors: ion channel receptors. [A 3D model of ion channels] (March 19th 202) https://www.drugtargetreview.com/news/57643/ion-channel-ball-and-chain-mechanism-imaged-after-decades-of-attempts/ Introduction Ligand-gated ion channel (LGICs) receptors are found especially in excitable cells, and are responsible for changing the potential gradient (the difference of charges between intracellular and extracellular spaces). Excitable cells are cells…
