Learn all there is to know about Ebola from Scishow


Hank Green, from SciShow, explains what Ebola is, and where is it coming from. It is not contagious as, let’s say, the flu, but it is nonetheless a deadly disease that can kill 90% of the infected victims. Ebola is transmitted to other hosts via direct contact (of your mouth, eyes, or open wound) with bodily fluids from the patients: vomit, urine, fecal matter, semen, blood. It transmits much like Hepatitis B.

So, in case you get near a guy with Ebola make sure to not touch anything they touched and stand at a certain distance. You’ll be safe. I wrote about Ebola before in this blog post. Even if it so deadly, if the patients are quarantined, the there is no such a big deal.

Cell vs virus battle: the war inside you


This TED Lesson lets us understand how cells work and how viruses act in our bodies. Each cell is like a whole country with a center, a powerplant, protective system, factories and so on.

When a virus enters a cell special enzymes surround that virus and feed off of it, killing the virus. We need to know that a virus is 1000 times smaller than a bacterium and a bacterium is 100 times smaller than a normal cell in our body. A virus is small, but it can multiply thousands of times in each cell and then spread out like crazy.

So, watch out. When you need to take the vaccine, simply take it and let your body be prepared for the fight.
