Video Post: I learned that crude oil is completely useless without having the different carbons taken out of it. By using a process called fractional distillation. The lower molecule compounds evaporate easily and get taken out first then different methods are used to get the heavier compounds from the crude oil. I thought it was really interesting that no vehicle or person uses crude oil as a fuel. Instead they need to separate the compounds and then use the different leveled compounds for different uses.

Austin, Good points. BTW they are hydrocarbons not carbons. 5 stars. MW

I read the article about how scientist are creating artificial blood to substitute lost blood. One thing I knew was hat hemoglobin is key to binding oxygen protein to the blood. Another thing I learned from reading the article is that donated blood only has a shelf life of 28 days. The final thing I learned is that HIV is a major concern to people accepting blood donations. I learned that hemoglobin is deadly outside the body. I also learned that people tried salt water and eve urine as a blood supplement. The last thing I learned is that people used wine as a blood proxy.

Austin, I can see you learned a lot from this article but I was looking for three things you already knew also. 4 stars. MW
