Understanding Viruses part 1/17
By
Your body is under attack every minute of every hour of every day. The enemy is patient, adaptable, potentially deadly, and invisible. Called the “littlest assassins” and “phantom killers,” viruses range from the common cold to HIV and have caused epidemics more devastating than war. This video explains how viruses operate and how your immune system defends you. And it shows scientists turning the tables, transforming invading viruses into agents of healing.

quite terrifying.
at the end of the entire video clips, it basically says we’re screwed, because at some point there will be a virus that will kill us faster than we can kill it.
and everyone thought that global warming was the biggest threat..

Great movie.
Discovery production ? Wow…
It must be old video, because today Discovery productions are piece of sh.t.

Rockefeller University eh? Louis Pasteur’s “germ theory” which has only created the current medical disaster paradigm we are in today.. Hmm.. The failure who profited off of manipulating data also sounds a lot like the Rockefeller owned Big Pharma drug cartel of today.

Already two errors in this video:
1. Viruses are NOT classified as living organisms.
2. Kuru is NOT caused by a virus, but rather by a prion.

I think one of the more recent definitions places virii into a category of parasitic chemical/genomic infection. They are unable to grow unless they are inside their host organism. Ergo, not life. Kind of a “grey area” definition, but one that seems much more accurate. A gene creature.

Look whether or not viruses are living or not is a matter of opinion among scientists.

Short answer: allosteric proteins.

Damn them terrorist germs!!!!!

I understand, I’m just telling you what I’ve been taught at the university of alberta. I took the course in the fall of 07

They move, but that does not prove that they are living. Chemotaxis and transmission by medium movement do not mean a virus is alive.

WHEN did you take these courses? I have 3 virology textbooks at home, and only the oldest one says that viruses are living. The other two say that they are not. At lot has changed in the last two years alone. Be logical and find the biological criteria used to asses life, and place viruses on that scale.

dude you are so wrong. I took virology courses at the university level. Viruses are acellular living organisms ok?
June 11th, 2011 at 1:11 am
If they don’t m,ove how do they inject their genetic material into the host cell?

Man, you are LUCKY, KajiMotomiya !

I honestly didn’t think this’d be on YouTube. My Bio teacher showed us this movie, but I slept through half of it. And I have to do a report on it.
Thank you, Obelisk! You really saved my hide!

Assertion. They are considered self-replication molecular aggregates, because they are simply infectious packets of DNA with no capability to carry out any metabolic function, which is a necessity for a thing to be considered living.
June 11th, 2011 at 2:31 am
yes they are … theyre acellular living organisms

But virus are not consitered “living” because they are not made up of cells, they cannot reproduce without a host ans they cannot move like bacteria do, so most scientist(and some people) belive that virus’ are not living.

Sounds like Murphy Brown doing the voiceover.
