Why we get Fat AND Hungry | (Biology of Weight Gain & Low-Carb )

Growing up in Texas, I thought that the weight gain of people around me was just something that naturally happened. Though, I didn’t realize how big us Texans were getting until I saw Morgan Spurlock’s “Supersize Me!” and he mentioned how 5 of the fattest cities in America were in Texas. This was surprising, but …

Plant Cells vs. Animal Cells: Compare & Contrast!

Plant Cells vs. Animal Cells: Compare & Contrast!

Welcome back, everyone! Today we’re going to be contrasting plant and animal cells. A lot of videos cover the different organelles, but this video does that AND compares how the different cell types tackle the same problems. At the end, we’ll also be organizing all that information into a handy chart that makes a great …

Nucleic acids – DNA and RNA structure

Nucleic acids – DNA and RNA structure

In this video we will study about nucleic acids. Nucleic acids are basically biopolymers, which are made of monomeric units known as nuclotides. We have two important functions for nucleic acids, that is, they hold our genetic information and they perform a variety of other functions that we will discuss later. We have two important …

Inconspicuous protein key to deadly blood cancer

Inconspicuous protein key to deadly blood cancer

We have been studying a kind of leukemia called MLL fusion leukemia we already knew it was driven by the MLL fusion protein and any MLL fusion protein might be able to fuse together with around 120 different fusion partners so this is why it’s very difficult to stop it so based on our study …

Scientists Can Implant Fake Memories in the Brain, Here’s How

Scientists Can Implant Fake Memories in the Brain, Here’s How

Human memory is unreliable enough as it is, but researchers interested in better understanding how and where our memories are stored are developing new ways to manipulate them. The search for memory “engrams,” a collection of identifiable neurons that physically represent a memory, has occupied scientists for over a hundred years. Turns out, memory is …

Introduction to Biochemistry

Introduction to Biochemistry

Hey, it’s professor Dave, let’s talk about biochemistry. What is biochemistry? Is it biology? Is it chemistry? Well as you might guess, it’s sort of in-between, quite literally in terms of size. In the great panoply of the sciences, biochemistry sits right here. If we go smaller we get into small molecules made of just …
