Immortal Jellyfish

We just learned about the Lion's Mane Jellyfish.

Another type of jellyfish is the Immortal Jellyfish, also called the turritopsis dohrnii.

This type of jellyfish does not get very big, less than one inch when it is fully grown.

This jellyfish starts out as a tiny baby jellyfish on the ocean floor.
When it grows up, it turns into a little bigger jellyfish and swims around the ocean looking for food.

If it gets hurt or is starving too badly, it can actually turn back into a baby jellyfish and start all over on the ocean floor!
That's like a grown up human turning back into a baby and starting life all over!

Because these jellyfish could do this over and over forever, they are called the immortal jellyfish, because immortal means you live forever.

Sublingual Caruncle

We just learned about the Fimbriated Fold.

Another part of the mouth is the Sublingual Caruncle.

Sublingual means "underneath the tongue", and caruncle means some skin sticking out like a bump.

Remember the frenulum is the piece of skin under the tongue that holds it in place.
On each side of the frenulum is a little bump.
That bump is the sublingual caruncle, and it is where most of the saliva or spit in your mouth comes out of.

Wall Walk

We just learned about the Zwinger.

Another part of a castle is a Wall Walk.

On top of the castle wall sometimes there is a pathway, with a small wall next to it.
People could walk on the wall, but still be protected by the small wall.
They could also look out to see who was coming, or shoot arrows or throw things down on any attackers.

Edict of Serdica

We just learned about the The Great Persecution.

Another part of early Christianity was the Edict of Serdica.

Remember that in 303 AD the Emperor named Diocletian started the Great Persecution, where Christians were killed and churches were burned down.
Later on a new Emperor took over named Galerius, and in the year 311 AD he decided that they should stop the Great Persecution.

He wrote a letter that was called the Edict of Serdica, which said that they tried to stop Christians from worshipping Jesus and tried to force them to worship Roman gods but it wasn't working.
So they decided to just let Christians worship Jesus, and not try and force them to worship Roman gods anymore.

This was the first time ever in history that rulers of any country made a law saying that it was ok to be a Christian.

Norwegian - Our table is short

We just learned that in Norwegian:
This house is big: Dette huset er stort
This chair is small: Stolen er liten
My drink is cold: Min drikke er kald
your food is hot is Maten er varm
and their car is tall is Deres bil er høy

To say our table is short you would say Vårt bord er kort.

Our - Vårt - sounds like voh-rt
table - bord - sounds like boo-r
is - er - Sounds like ay-r
short - kort - Sounds like koh-rt

So all together To say our table is short you would say voh-rt boo-r ay-r koh-rt.

Toxicology

We just learned about the Fingerprints.

Another part of forensic science is Toxicology.

Long ago when someone died and it was a mystery, it was very hard to tell what happened.
If a bad person had killed someone by using poison, there was no good way to prove it so they could be sent to jail.

In 1832, a scientist named James Marsh came up with a test that could be used to show if a poison called arsenic was used to kill someone.
Arsenic did not have a smell or a strong taste, so people would sometimes sneak it into someone's food to poison them.
With the Marsh test, they would take some liquid from the body of the person that was poisioned.
Either some blood, or saliva (or spit) from their mouth, or urine from their bladder.
That liquid would be put into a bottle with some other chemicals, then burned up with some other gases, and then if it left a silvery black stain after being burned, it was proof that arsenic was used.

After Marsh proved to everyone that this test worked, it was used by police all over the world to put people in jail for trying to poison other people!

Because this worked so well, people worked on coming up with other ways to test for chemicals in a person's body.
These days scientists can test hair, blood, saliva, sweat or even food that is in the intestines that was not totally digested yet.

Toxicology helps the police prove what the truth is, using the evidence that is in the body!
