Meapz4Science News!!!
Hello everyone! You can probably tell by the title that THIS post is going to be WAY different Than what I normally do. This is... Meapz4Science News! Today I will tell you about an article I found. It is called Sleep Therapy for Fears. I know, right? It was written by Stephen Ornes. It states that a new study has shown that while sleeping, a person can lessen their fears.

 
     Katherina Hauner and Jay Gottfried are at Northwestern University’s Feinberg School of Medicine in Chicago. and they made up a test. They recruited 15 volunteers. Hauner and Gottfried showed the participants photos of a man’s face. At the same time, they smelled a particular scent (such as that of lemons) and received a small electric shock. They repeated this experience several times over half an hour for each subject. It started to leave the recruits fearing the face and the scent — because both were linked to the horrible shock. How did they know? There was one way scientists measured this fear: The volunteers sweated more.


     After they recorded that data, the scientists had each subject fall asleep in the lab. When the subject fell into the deepest stage of sleep, the researchers put in the fearful smell. Upon waking, these volunteers showed less fear when encountering the once-frightening face and smell. But sleep alone did not erase the fear. What they smelled during sleep was important. The scientists know that because they trained the volunteers to also fear a different face/smell combo. But the researchers didn’t deliver that odor to volunteers while they slept. And afterward, they found that face just as scary as before.


     Brain scans also showed that sleep-scent training also altered parts of the brain involved with different memories and/or emotions. The Northwestern scientists and their coworkers published all of these findings September 22 in Nature Neuroscience. The new sleep-scent treatment resembles something known as exposure therapy, Hauner told Science News. During exposure therapy, a person confronts a fear over and over. Such as a person with a fear of spiders may interact with spiders, eventually even learning to touch them. This therapy continues until new, safe memories replace the fearful ones (Yeah, I have a huge fear of spiders, NOT HAPPENING!)

 As such, the new findings also suggest that sleep-scent therapy may be able to help  with the success of treatment for disorders like phobias. Phobias are extreme or irrational fears. (Arachnophobia, for example, is the fear of spiders.) The new sleep treatment may also lessen deep-seated fears in people with post-traumatic stress disorder. People with this condition suffer severe mental or emotional stress after an injury or shock.

Well, that is the end of the article. Personally, I think that the article is very interesting. I would try it, IF I could ever get to SLEEP in the FIRST PLACE! I like the whole testing thing, but the part with the spiders? NO WAY AM I TOUCHING A DANG SPIDER! They are terror on 8 hideous legs! Anyways, i hope you all enjoyed Meapz4Science News! I don't know if I'm going to do anymore, but I still hope that you guys are enjoying. I'm Emma the meap, and I will see you next time. PEACE!!!

Galaxies!!!
Hello everyone, and welcome to... Meapz4Science! Today, we will talk about something so immense, It makes up most of our universe! Today, we will talk about... Galaxies!!! We will talk about their shapes, and what they are, and so much more! Let's go!!!
 
Man, we do this a LOT now! Technology, baby!
Alright, we are here. You might ask, what the heck is a galaxy in the FIRST place? Galaxies are huge group of stars, gas, and dust held together by gravity. We have over 10,000 galaxies in the whole universe. And there can be anywhere from 10 million to 1 trillion stars in each galaxy! That is a LOT to wish on! I'm kidding. Anyways, let's start out with the smallest type of galaxy, the Irregular Galaxy, such as this one:
 
Irregular galaxies are very small, and contain only young stars. It is what the name implies. It has no real shape. Not a single irregular galaxy looks like another. That is REALLY cool! Anyways, the next galaxy is the Spiral Galaxy, such as this one:
 
 Spiral galaxies are what we all think of when we think of galaxies. They are like pinwheels in space. They also contain middle-aged stars. The next one we have is the Barred Spiral Galaxy, Such as our own Milky Way.
 
Barred spiral galaxies are basically spiral galaxies with the bulge being a bar to which arms spiral out of. Lastly, there is the Elliptical Galaxy, such as this one:
 
Elliptical galaxies are sort of like spheres of stars. Also, they contain old stars. Anyways, scientists believe that there is a super massive black hole in the middle of every galaxy. We have to go back home to talk to someone very important. Edwin Hubble! Let's go!
 
Now we will have to time travel to when Hubble made his discoveries. Let's go!
 
Okay, we are here. Look! there is Edwin Hubble!
 
Awesome! I'm going to say hi!
 Me: Hi, Edwin Hubble! How are you today?
Hubble: I am the happiest man in the whole universe! I just made a HUGE discovery!
Me: Cool! What is that discovery?
Hubble: Well, I just discovered with my telescope that we are not the only galaxy out there!
Me: Oh, cool! That's great!
Hubble: That isn't even where it stops! I also found they are all flying away from each other!
Me: That is a HUGE discovery! Well, I have to go now! Bye!
Hubble: Okay. Bye!
Wow. That was eventful! Now, we will  talk about two things call the Redshift and the Blueshift. These have to do with the expansion of the galaxies. So we have to go into space again. Let's go!
 
Okay, we are now in space! Before we get into the different shifts, I need to tell you about Wavelengths. Wavelengths are literally the length between the top of one wave to the other. The redshifts and blueshifts have different wavelengths. The redshift occurs when a star starts to move away from us. It would emit light on the red side of the visible light spectrum. If it was moving towards us, it would emit blue light, creating the blueshift.
 
I think that is all for today. Let's go home.
Alright, we are now home. I hope you all learned a lot today. Also, feel free to check out my other blog posts on the Milky Way, Stars, and Black holes. I will see you next time. PEACE!!!
