1. What is RNA?

Most of us have heard about DNA – it’s the blueprint for all living things. Well, RNA is like DNA’s cousin. If DNA is the recipe book of our cells, RNA is the chef who reads the recipes and helps make things happen. RNA turns the information in our DNA into action, helping to make proteins that our bodies need to function.

2. Why Study RNA?

By studying RNA, scientists can understand what's going on in our cells at any given time. It's like listening to the chatter in a busy kitchen. The chefs (or RNAs) are talking about the dishes they're making, how fast they're cooking, and which ingredients they're using. By listening to this chatter, we can learn a lot about the health and function of the kitchen, or in our case, the cell.

3. What is RNA-Seq Analysis?

"RNA-Seq" is short for "RNA sequencing." It's a technique that lets scientists take a snapshot of all the RNA present in a cell at a particular moment. Imagine you could hear every conversation in a room all at once and then write it all down to analyze later. That's sort of what RNA-Seq does, but for our cells.

4. How Does RNA-Seq Work?

Without getting too technical:

1. Collection: Scientists take a sample from a living organism, like a piece of plant, a drop of blood, or a swab from inside your cheek.

2. Extraction: They extract all the RNA from this sample.

3. Reading the RNA: Using super cool machines, they "read" or "sequence" the RNA, turning it into data that can be analyzed on a computer.

4. Analysis: Scientists use computer programs to sort through this massive amount of data. They look for patterns, changes, or anything unusual that might tell them more about the cell's health or function.

 5. Why Is RNA-Seq So Cool?

Imagine you're trying to solve a mystery in a big city, and you have the power to listen to everyone's conversations at the same time. By doing so, you can find clues, understand what's happening, and maybe even prevent something bad from happening. That's the power of RNA-Seq for scientists. They can learn about diseases, find new treatments, and understand more about the mysteries of life.

6. In Conclusion

The world inside our cells is bustling with activity, and RNA-Seq is one of the tools that help us peek inside. It's like a super-microphone that listens to the life of our cells. So, the next time you hear about a breakthrough in medicine or biology, remember: it might have started with a tiny piece of RNA and a scientist curious enough to listen.

TL;DR Science - Vitamins and Minerals

Regardless of our age, we’ve always been told to eat balanced.  Fruits and vegetables form a large part of that ideal diet.  However, we don’t always think about why that is; sure, they’re healthy, but what makes them so important to our eating habits?  What about proteins – what makes lean meats or lentils the central focus of many of our plates?  The answer is pretty simple: all these foods are packed with nutrients.

TL;DR Science: Prosthetics

Exploring the world around us requires us to use our five senses, but what if one of those senses was made impossible to use?  Most of us could never imagine living life without our hands, arms, legs, or feet, but this is a reality for so many around the globe.  Prosthetics are a means for those people to improve their quality of life, but what goes into these devices and what implications (both positive and negative) do they pose for users?  Check out this week's article about prosthetics!

TL;DR Science: Allergies

Have you ever wondered why some of us are unaffected by springtime pollen while others find themselves sneezing?  Or why not everyone can enjoy a good peanut butter and jelly sandwich without having a reaction?  What really causes these allergies, and why do they vary among different people? Find out more in this week's article!
