A Solar Cell or Photovoltaic Cell (PV cell) in the most basic definition absorbs the sun's light and converts into electrical energy. In this post, we explore an in-depth description of the function of a PV cell. Understanding this mechanism is important as this field is rapidly advancing, producing much smaller and more efficient PV [...]

The Times When the Earth Froze Over
Hey guys, in ironic celebration of the start of Summer, we are going to cover the few periods of Earth's vast geologic history where we had an Ice Age so strong, it froze the world over. There are few times that the Earth completely or nearly froze over. The first was the Huronian glaciation which [...]
An Overview of the Phyla of Animalia (Intro to Animals part 3)
Hey guys, this is part 3 of the Introduction to Animal Diversity posted by Neil and Sai earlier today. This post will cover the major phyla of Kingdom Animalia and give major features. It is assumed that you read and understand part 1 and 2 of this guide. Last time we discussed Porifera, Cnidaria, Platyhelminthes, [...]
An Overview of the Phyla of Animalia
Hey guys, this is part 2 of the Introduction to Animal Diversity posted by Neil earlier today. This post will cover the major phyla of Kingdom Animalia and give major features. It is assumed that you read and understand part 1 of this guide. Lets jump in. The phyla of Animals are extremely diverse as [...]

Intro to Photosynthesis, Leaf Structure, Nature of Light, and Pigments
Welcome to our continuing AP Biology/ General Biology series here on STEM Talks! The purpose of this post is to get our readers accustomed to photosynthesis so that when we dive into the in-depth nitty gritty later on, they will be right at home. We will begin with a short summary of photosynthesis: Photosynthesis is [...]
Electron Transport Chain and Chemiosmosis
The Electron Transport Chain and Chemiosmosis is where the vast majority of the ATP is synthesized. This is what makes Aerobic Respiration far more efficient per glucose than Anaerobic Respiration. Lets Review: So far in Glycolysis, Acetyl CoA step, and Krebs we have made 4 ATP, 10 NADH + H+ , and 2 FADH2. Note [...]
Glycolysis and the Acetyl CoA step
Hey all, this post will be part of our AP Bio/ General Bio series! Keep up with the blog for more content like this! Cellular Respiration is the process of converting glucose molecules to molecules of ATP, used in various cell processes. There are three main stages of respiration: Glycolysis, the Krebs cycle, and the [...]
Cell Cycle Control and Cancer Implications
Hey all! This blog post is a part of STEM Talks' ever expanding General Biology Series. For this post, it is recommended you understand the basics of cell division and cell cycle phases. The cell cycle seems to be governed by cytoplasmic and extracellular signals. A cell cycle control system controls the cell cycle. It [...]
Zinc Finger Nuclease (ZFN) led Editing – CRISPR and Genomic Editing (Part 2)
Hello All! This will be the 2nd part of a 10+ part post series summarizing current research on Genome Editing and CRISPR. After that I will be moving onto its applications in various diseases such as Cancer. The first few posts will be my summary of research articles that came out in the past few [...]
