The number of infections spread through sexual contact is increasing globally. Why is this? What are STIs? And why do some people not know when they've caught one? Biology - Healthy Living - Sexually Transmitted Infections (STIs) are...

What is cholera exactly? Believe it or not, this disease isn't gone, it's still an issue in various parts of the world. It's caused by Vibrio cholerae, and in particular two serotypes of this bacterium. Let's get some details!

The video discusses the global issue of tuberculosis and the efforts of Yanson Pharmaceuticals in Belgium to develop a new drug called TMC207 that could potentially revolutionize TB treatment.

In this video, we explore the functions of neutrophils, macrophages, and dendritic cells.<br/>

Practical examples show how viruses and bacteria are both beneficial and harmful to humans. Animations describe the structure of a virus, and explain how they reproduce and cause disease. Microscopic images illustrate different types and...

From part 1, we discovered how to culture bacteria ensuring there is no contamination… in this video, we’re going to look at how we can calculate the size of our newly cultured populations.

Thermus aquaticus is the most important bacterium you may never have heard of. It single-cell-edly revolutionized modern biology and our ideas about the very limits of life on Earth. Who said a Bizarre Beast has to be an animal?

We've learned about a few techniques in biotechnology already, but the CRISPR-Cas9 system is one of the most exciting ones. Inspired by bacterial immune response to viruses, this site-specific gene editing technique won the Nobel prize...

This is a short lecture presentation on bacteria. The video discusses the similarities and differences between bacteria and animal and plant cells, and looks at a particular example of the bacterium, cholera. The video then goes into...

Viral Replication - Viruses/Immunity Set - Part 2 This clip examines the process of viral replication in Bacteriophage Viruses and in the Human Immunodeficiency Virus (HIV).

Finally! After talking about atoms and molecules in chemistry, big molecules in biochemistry, and all the parts of the cell in this biology series, we are finally ready to look at entire living organisms! But we have to start with the...

This exciting program takes a glimpse at some of the amazing advances in modern genetics. Starting with the discovery of DNA, students will be exposed to advances such as the creation of recombinant DNA, vaccines, the human genome...

Most of us know about anthrax either because of the terrorism involving sending anthrax in the mail, or because of the metal band by the same name. But let's get a closer look at the actual bacterium, Bacillus anthracis.

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

What are drugs? What do they do? How do they do what they do? These questions are part of the field of pharmacology, and over this series we will learn all about a wide variety of different drugs that have clinical use. This will require...
