Cell vs. virus: A battle for health - Shannon Stiles

View full lesson:

All living things are made of cells. In the human body, these highly efficient units are protected by layer upon layer of defense against icky invaders like the cold virus. Shannon Stiles takes a journey into the cell, introducing the microscopic arsenal of weapons and warriors that play a role in the battle for your health.

Lesson by Shannon Stiles, animation by Igor Coric.

The Immune System

This video describes the Immune System and explains how it detects and attacks any foreign organism that enters the body.

We learn how the team in the MRC Centre for Transplantation at King’s College London have developed a way to harness the power of the Immune System after a transplant, whilst maintaining the body’s capacity to resist infectious diseases.

The Difference Between Bacteria and Virus.

Short explanatory video about the differences between Bacterias and Viruses.

How do viruses jump from animals to humans? - Ben Longdon

Discover the science of how viruses can jump from one species to another and the deadly epidemics that can result from these pathogens.

--

At a Maryland country fair in 2017, farmers reported feverish hogs with inflamed eyes and running snouts. While farmers worried about the pigs, the department of health was concerned about a group of sick fairgoers. Soon, 40 of these attendees would be diagnosed with swine flu. How can pathogens from one species infect another, and what makes this jump so dangerous? Ben Longdon explains.

Immune cells attack to eliminate viruses and bacteria

Flu Attack! How A Virus Invades Your Body | Krulwich Wonders | NPR

When you get the flu, viruses turn your cells into tiny factories that help spread the disease.

Subscribe to NPR!

In this animation, NPR's Robert Krulwich and medical animator David Bolinsky explain how a flu virus can trick a single cell into making a million more viruses.

Virus Rapidly Evolves To Fight Bacteria

Michigan State University researchers have seen for the first time that the Lambda virus can mutate in a short time (4 mutations in just 12 days) and found new ways to attack host cells.

Using Cancer To Fight Cancer | Vikki Academy

T-cells are white blood cells that help defend our bodies - they are equipped to identify foreign threats. But cancer cells have the ability to trick white T-cells by sending proteins that suppress them.

5 Intriguing Facts About Viruses | UCLA Health

Viruses are incredibly simple, arguably the most simple living organisms on the planet. They have no brains, no metabolism, and they can’t reproduce on their own. Yet they are able to wreak incredible havoc on our bodies and to outwit the scientifically advanced weapons that humans have invented to fight their spread.

Ebola continues to ravage Sierra Leone and other parts of West Africa. Meanwhile, here in the US, a particularly virulent strain of Influenza is currently widespread in 46 states.

What makes viruses so potent? How do they keep surviving? Dr. Otto Yang, a UCLA infectious disease expert, and Professor Bill Gelbart, a physical chemistry-trained scientist who studies viruses, suggest their genius may be their ruthless efficiency.

Sorry to say I did not make this video. I found it on a website a few years ago and downloaded it. I could not find it again afterword and could not find it on youtube so I posted it up. If anyone knows who made it ill be glad to post that up for credit.
