Leukemia

We just learned a little about Blood Cancer.

One of the three types of blood cancer is called Leukemia.

The word leukemia comes from the words for white and blood, because this is a cancer of the white blood cells.

This disease usually starts in the bone marrow where all of the blood cells are being made.
A type of blood cells called blasts that are not totally made right start getting made in the bone marrow and sent around the body.

These blasts take the place of normal healthy blood cells and then the body gets sick because it doesn't have the right kinds of blood cells doing the right jobs.

There are 4 main kinds of leukemia:
- Acute lymphoblastic leukemia (ALL)
- Acute myeloid leukemia (AML)
- Chronic lymphocytic leukemia (CLL)
- Chronic myeloid leukemia (CML)

The different types of leukemia depend on which types of blood cells are having problems, and how fast the cancer is spreading.

This is a small country that borders Estonia, Lithuania, Russia, Belarus, and the Baltic Sea.

The flag of Latvia is red with a white stripe in the middle.
There is an old story from Latvia of a soldier who wrapped himself in a white blanket before he died, and the blood colored the rest of it white.
The other soldiers used that colored flag to help get everyone to fight and win their war.

Heliocentrism

We just learned about the Believer's Baptism.

Another part of early Christianity is Heliocentrism.

Long ago people in the world saw the sun come up one side of the sky and then go down in the other.
People thought that the world was flat, and the sun was up in the sky going around the earth.
Later on people changed and agreed that the world was not flat but that it was a globe, but they still believed that the sun went around the earth.

Through the years a few scientists tried to tell people that the earth actually went around the sun, but people did not believe them.
The idea that the earth is at the middle of the universe is called geocentrism.
The idea that the earth actually orbits around the sun is called heliocentrism.

In 1610 AD the astronomer Galileo wrote a paper called "Sidereus Nuncius" which means Starry Messenger, telling people about how he beleived the earth orbited around the sun.

The church was very upset because they believed that if the earth was not the center of the universe, then that would mean it was not special or that it went against something that was in the Bible.

Galileo was put on trial and was found guilty, and told he was not allowed to teach people that because they thought it was not true.
The astronomer Copernicus had said the same thing many years earlier, but people did not believe him either.

Galileo's and Copernicus' books were banned for their whole lives, and the church did not allow them to be printed until about 200 years later.

Throwback - Tony Smith

We just learned about the S, Metal by John Chamberlain.

Another famous American sculpture is Throwback by Tony Smith in 1979 in Washington DC.

Smith was born in 1912 in New Jersey, and was very sick as a child.
He grew up during the depresson, and went to an art school in New York while he was growing up.
Later on in life he worked as an architect and an art teacher in college.

He was known for making what was called Minimalist art, which was artwork that was very simple looking, but was still very interesting.

For his sculpture called Throwback, it was a 7 foot by 11 foot sculpture made of aluminum that was welded together.
The pieces were all at different angles so they made a sort of squarish ring with a lot of edges.

Smith really liked geometry, which is how shapes look and work together, so this sculpture that had a lot of different rectangle type shapes connected to each other in interesting ways.

Orangutan

We just learned about the Gorilla.

Another type of primate is the Orangutan.

The orangutans have orangey red colored fur, but their name doesn't come from their fur color.
In Malay the word "orang" means person, and "hutan" means forest.
Because these apes looked like furry people walking around the forest, long ago people actually thought they were just really hairy people!

Orangutans live most of their lives climbing around in trees and eating fruit.
They have really long arms which helps them climb, and they even make nests in trees to sleep in at night.
These animals are very smart, and have learned to use tools to get food.
Some orangutans like to eat bugs, honey or bark, and they will take a stick that they sharpened with their teeth to open up tree bark or to crack open fruit to eat the inside.
If an orangutan really likes the tool that it used, it will save it and collect other tools in their own little toolbox.

When orangutan males grow up, their face changes a lot, and grows to be flat and wide.
Orangutans don't live in family groups like chimpanzees or gorillas, they mostly live alone except for young ones that live with their mother for a few years.

There are three main different types of orangutans that live in different parts of the world and look a little different: Bornean, Sumatran, Tapanuli.

All wild orangutans live on the island countries of Borneo and Indonesia.
