NASA Sent Several Mice Into Space To Analyze Their Behavior In Microgravity—And The Mice Actually Had A Blast

Mice are the often unsung heroes of humans' scientific research. We use them as a proxy for our own species when researching how things might affect humans.
Obviously, we aren't mice, but their bodies are similar enough that they can tell us a lot about the safety of different medications or situations.
Mice also live shorter lives than humans, so they are excellent for testing the long-term effects of microgravity—like that experienced during prolonged space travel.
Humanity is getting closer and closer to taking a trip to Mars but, before we can make that idea a reality, we need to learn how being weightless for the amount of time it takes to get there will do to the astronauts that take the trip.
Rodent Research in Microgravity www.youtube.com
In order to study how mice react to the microgravity of space, NASA designed a special enclosure to hold and observe mice on the International Space Station (ISS).
Called the NASA Rodent Research Hardware System, the enclosure had enough room for the mice to move around freely.
A researcher from NASA's Ames Research Center, located in Silicon Valley, talked about the enclosure
Studying Behavior in Space Shows Mice Adapt to Microgravity www.youtube.com
Surprisingly, the mice didn't seem to mind being in space at all!
They did all of the same things that the control group of mice who stayed here on Earth did: grooming, eating, and interacting with the other mice in the enclosure (including adorable snuggle huddles—mice are very social animals).
They also did some things that the earthbound mice didn't, mostly because they couldn't. The space mice rapidly adjusted to the microgravity quickly, and some of the younger mice began doing what scientists called "race tracking."
They would run laps around the walls of the cage, eventually in groups!
Scientists aren't sure of the reason for these mousy jogging clubs, but they could be do to a few different factors.
It might be because the mice enjoy the physical exercise itself, like many human runners, or the motion helped stimulate the mice's sense of balance.
There is also the possibility that it is a stress response, but scientists think this is the least likely possibility. The mice were in perfect health, and didn't show any other abnormal behaviors.
Ronca commented on the importance of mouse research and the success of this initial study.
"Our behavioral study shows that the NASA Rodent Hardware System provides the capability to conduct meaningful long-duration biological research studies on the International Space Station."
"Experiments conducted in the habitat can focus on how mouse physiology responds to the spaceflight environment during extended missions and on similarities in response to astronaut crew."
Twitter users were excited by the study's results.

If we really plan to make it to Mars, or even farther planets, these studies of the effects of being in space are vital. The ISS is too small to conduct a large-scale study on humans, and a sufficient number of samples are vital to understanding whether a reaction is a species-wide one or just an individual one.
These mouse studies are the first step in understanding the effects of space on bodies that are designed to exist with significantly more gravity.
All of us have fears which some might call irrational.
Up to and including ghosts, witches, monsters.
But more often than not, reality can be far scarier than the supernatural.
And there are very few people indeed who don't have a memory of a moment when they were truly and genuinely scared.
And not by an otherworldly encounter, but by things that could quite literally happen to anyone.
Redditor GodhimselfUwU was curious to hear the scariest experiences people have lived through, leading them to ask:
"What’s the scariest non-supernatural thing that ever happened to you?"
Intruder
"I was 14, alone at my grandmas house around midnight."
"She was across the street at the bar she owned."
"I was playing games on her computer, about 15 feet from one of the windows facing the backyard."
"All of a sudden the glass from that window shatters, and I ran to one of the bedrooms."
"I can hear my name being called."
"Eventually I see my grandma's ex-boyfriend enter the living room where the computer is."
"He keeps saying my name."
"I’m scared sh*tless, but I walk out and confront him."
"He says my grandma stole his ID and that’s what he came for, as he’s taking money from my grandmas purse."
"He looks f*cked up on something."
"I forget how he leaves but when he does I call the bar and people come over looking for him."
"They didn’t find him."
"About a year later he did it again, and I was once again alone there."
"Except this time instead of breaking a window he decides to try to kick the side door in."
"I’m just there chilling when out of nowhere I hear the loudest bangs coming from the side of the house and I instantly knew what was happening."
"I immediately called the bar and they sent a bunch of people over before he could make it in."
"He apparently tried to jump from one of her sheds into the alley next to her house and broke his leg."
"He went to prison."- nfreshn
They're coming right for us!
"Two bison charging right toward me down a narrow wooded path in Yellowstone when I was 12."- pcc2
Uncomfortable in new surroundings.
"My sister has mental health issues."
"We were in a foreign country, driving across mountains on a one lane dirt road with no guardrails."
"She had a complete mental breakdown and threatened many times to drive off the edge."
"To this day, my mom swears my sister wouldn't have done it."
"All I say is, 'you weren't in the car'."
"'You have no idea'."- BlorengeJulius
Lost in the woods.
"Getting lost on 350 acres of woods in southeast Georgia."
"Was found about 6 hours later."
The dog found me hours before the people did.- No_Regrats_42
A near death experience.
"Was working as a linemen tasked to replace a 16m wooden power pole which requires climbing up to untie the lines from the isolators."
"I checked if the pole had any rot beforehand, climbed up, untied the lines, climbed down, as I was packing my tools up , the pole fell from its own."- LimaRadek
He wasn't who he claimed to be.
"A man claiming to be a meter reader was in our yard and tried the back door AFTER trying the front."
"It was unlocked because there was a field behind us and our gate had a lock, that he somehow got by."
"The meter reader man was nearly eaten by our Great Dane who was dumb and peaceful, except for when she laid eyes on him."
"Our other dog also wanted to kill him and he was up on our trampoline begging us to call the dogs off, which we, my then 11 year old sister and I, refused to do and went to get our dad, who worked from home."
"The guy escaped while we got our dad and my dad let the police know what happened."
"The real meter reader man came the next week."- Applesintheorchard
Had no idea what they were witnessing.
"I guess watching a loved one have a seizure when I didn’t understand what it was."
"Legit thought I witnessed a death."
"Scary stuff."- Peppapigisgodly
Always look both ways.
"I got hit by a car while in a crosswalk a few months back."
"Had a split second where I saw him coming and realized what was about to happen."
"I thought I was going to die."- jolalolalulu
Big Sister to the Rescue.
"Saved my sisters life."
"We were boating and my parents just kinda assumed we’d be ok with them only out a couple hundred feet."
"I was about 17 and she was about 7."
"I’m laying there chilling and see her slip and fall into the water and just straight up sink."
"Ran over, dove in and pulled her to shore."
"She spit up a bunch of water and was fine but that experience rocked me to my core."
"Not a super crazy story but almost seeing a sibling die has always stuck with me."
"I’ve broken almost every bone in my body, I died one time and was in a coma for a little bit but for some reason this one stuck with me."- Present-Trip5231
Often, an experience that left us scared does make for a good story down the line.
Though whether it was a good enough story to make having gone through the experience worth it, is debatable.

Having to work for a living is hard work.
Some jobs come with difficulty and two extra sides of stress.
So the last thing people need is unwarranted hate.
I'm so glad I work from home. Writing alone.
I have issues with me, but that I can deal with.
I do hate internet issues.
But that is warranted.
Redditor PM_ME_URFOOD wanted to talk about the jobs where a ridiculous amount of vitriol is all part of a days work. They asked:
"What profession gets an unjustified amount of hate?"
Waiting tables was always the bane of my existence. Customers are rude. Staff is rude. It never ends.

"Youth sports officials. I umpire baseball as a hobby and the way parents act is deplorable."

"The parents on the other hand deserve loads of hate sometimes. I was a coach for soccer and volleyball while I was in the Air Force. You would have loved to be a sports official for our leagues at our base. If a parent got sh**ty they are immediately ejected, no questions, and reported to whoever is their higher authority. It almost never happened."

"I did customer service for automotive companies at a call center for years. People get so unhinged, between dealerships, management, people calling into the wrong department, angry customers who were itching for a fight over a rental car. The job paid for five free therapy sessions a year, but honestly, it would take every ounce of restraint not to break some days."
"You aren't allowed to defend yourself or hang up, you can't transfer them to supervisors for a call, you technically work for a third party company that exists to keep the customer from ever actually speaking to the corporation. It was the worst job I've ever had, and that's coming from someone who used to work at a seafood processing plant."

Hard Hours
"I usually just lurk as a guest, but I made a Reddit account just for this. Cooks for public schools. They are constantly overworked, underpaid, and disrespected.

Short of having a shopping addiction, no one actually likes spending money on stuff.
Why would you ever willingly give it away? It's your money!
Which might be why it feels so bad when you have to spend money of something that should be free from the beginning. People/ corporations are going to chase that cheddar, though, so there's little you can do besides complain, which frankly might be the best thing the internet is for.
Reddit user, woodside37, wanted to know what we should never have to pay for again when they asked:
"What should be free?"
Let's get these out of the way first...No, let's get this first one out of the way first.
Hidden fees are the worst.
Hidden. F***ing. Fees.
"Transaction/processing fees when you order a digital product online. Such as a concert ticket, where you pay 6 euro extra while you pay online, and have to print the ticket yourself."

The worst part of having breasts is Florida.
I didn't even say large breasts. Just breasts, any breasts. Florida and breasts are mortal enemies sworn to battle one another into oblivion until the end of days.
In other states, you and your ladies can live a more peaceful life. Here in Florida, it's A Song of Sweat And Fire Ants.
Ever get tiny little jellyfish stuck under your side-boob? Happens here all the time.
Bikinis should come with a "Sand Lice, Your Titty Crease, And You" informational pamphlet.
Wanna jog? Hope you accounted for the fact that the air is soup and will chafe and cauterize your nipples.
Know what limits your field of vision, making you more likely to accidentally step on a snake and/or gator? Boobs.
Know what slows you down as you try to escape the angry reptile from the above paragraph? Also boobs.
Reddit user Saibotnl1 asked:

Now take all this stuff they said sucked, and then put it inside of a steam oven filled with mosquitos. That's Florida.
And Florida is incompatibile with breasts.
