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,…

Flame: A Phenomenon

Usually, we use the words “fire” and “flame” interchangeably. Technically speaking, fire is the state of combustion, which produces the visual part of burning: flame. As a kid, I wondered if flame is a solid, a liquid, a gas, or a completely undiscovered state of matter. It turned out that rather than being a matter, flame is actually a phenomenon. Background information Atoms & electrons Every matter is made…

Ernest Rutherford’s Gold Foil Experiment

In the previous article, we talked about how J.J. Thompson disproved Dalton's Atomic Theory. In this article, we will discuss the discovery of the nucleus by Rutherford. The beams are reflected and bent due to the nucleus. The beam is an alpha particle beam. credit The Gold Foil experiment was conducted by emitting alpha particle beams towards a gold foil. Most of the alpha particles from the beam passed…

J.J. Thompson’s Cathode-Ray Experiment

Once upon a time, after Dalton's Atomic Theory was released to the world, J.J Thompson conducted experiments that led to contradicting Dalton's theory. Thompson discovered the presence of subatomic atoms called electrons, disproving the theory that all atoms are indivisible. His model of atomic structure was known as the Plum Pudding Model (look carefully - it actually does look kind of like a plum colored pudding). The yellow circles…

The Story of Dalton’s Atomic Theory

Dalton's model of an atom Once upon a time, there was John Dalton, an English scientist. He was the one that started all of this madness into chemistry - yes, you have all right to despise him. He formed an idea called Dalton's Atomic Theory, the base of where all atomic structures came from. Dalton's Atomic Theory gives four main ideas to the field of chemistry: Each element is…
