Microbiology: Acid Fast Test

When we look at bacteria under a microscope, they appear to be tumbling around chaotically, but over the centuries we realized that their pathways have a purpose.

We recently discovered some Holospora infecting one of our Paramecium samples. How does that happen? How does the Holospora get in there? And how are they so successful at infecting?

If we want to understand a biological organism, we turn to the expression of its genome. Which genes are being expressed, and in which cells, and when? How does this differ between a normal cell and a cancer cell? We have incredibly...

Small green sea slugs puzzle scientists because they can photosynthesize energy, just like plants. These Eastern Emerald Elysia sea slugs also appear to have several different types of DNA. Scientists are hopeful these sea slugs might...

The Complicated Relationships of the Microcosmos

How to Survive the Microcosmos

The video discusses mutations in DNA and how they can affect the organism that carries them. It explains how mutations can occur in the coding and noncoding parts of DNA and how they can impact protein synthesis, specifically by changing...

This live-action video program is about the word decomposer. The program is designed to reinforce and support a student's comprehension and retention of the word decomposer through use of video footage, photographs, diagrams and...

Alright, so we've learned a lot about the origin of life. We learned about how the first organic molecules can have formed spontaneously, and how they might have assembled into the first protocell. From there, endosymbiotic theory tells...

This live-action video program is about the word pheromones. The program is designed to reinforce and support a student's comprehension and retention of the word pheromones through use of video footage, photographs, diagrams and...

Did you know that there are more microbes inside of you than there are cells that belong to your own body? There are tons of those critters all over the place! But don't freak out, most of them are actually helping you. They protect you...

Let's dive into the branching weirdness of the pulsating slime molds!

Strange Stentor Stories

This clip looks at some of the beneficial and harmful aspects of transgenic plants.

This video discusses the structure and function of DNA. The video also talks about the sequencing of the human genome and its potential applications, such as linking genes to diseases and tracing migration patterns. It provides a basic...

Alright, we've learned about how unicellular organisms came to be, how they became multicellular, and then from those how evolution by natural selection produced all the species in the world today. But there are so many! Millions and...

What Is Adaptation? | Ecology & Environment | Biology | FuseSchool Learn about how organisms adapt to their habitats. "Adapting and Living Together" within the Ecology and Environment topic for school level biology.

When we discuss zoology, we are always also talking about evolutionary biology. And with evolution, we are sometimes concerned with origins. What is the origin of animals? What is the origin of eukaryotes? What is the origin of life on...

This video covers:<br/>
1) What are Acid-fast<br/> organisms?
2) Two genera <br/>of Acid-fast orga<br/>nisms
3) How staining is done
4) Interpreting M<br/>icroscope Image (Acid-fast vs non-Acid-fast)

Colorful animations and crisp video footage illustrate the vital process of circulation. The major characteristics and features of the circulatory systems are explored, with special emphasis placed on circulatory problems and caring for...

On this week's journey, we explore the ways things eat in the microcosmos, from Stentors filter feeding to Dileptus hunting down and absorbing its prey.

A mutation is a random change in the DNA. Mutations can be neutral, which means it does not cause a change in a trait of the organism, or it could cause a beneficial or a harmful mutation. There are a few different types of mutations -...

The human genome project was an enormous project that saw scientists around the world collaborate to work out the sequence of bases in the human genome. The project started in 1990 and was completed in 2003, 2 years ahead of schedule....
