These tiny creatures are some of the scariest living things on Earth.

This is a natural thing.

Zombies ... what if I told you that they're everywhere?

Hold on to your brains. Here's the story:

You know about your run-of-the-mill parasite — where one insect lays an egg inside another, and when the larvae hatches, it consumes its host from the inside out until it's ready to emerge and take over the world?

It seems that many parasites take things a step further:

These kinds of parasites bend their victims' wills to serve a new master.

The horsehair worm grows up inside a cricket and then drives it to commit suicide by drowning.

The horsehair worm needs water in order to reproduce. When it's old enough to mate, the parasite releases proteins that cause the crickets to become suicidal in a very specific way: by drowning. A host cricket finds water and flings itself in. While it drowns, the horsehair worm wriggles its way out, free to hit the singles scene.

And this isn't an isolated thing either. One scientist in Japan found that in one stream, deviant suicidal crickets made up 60% of the diet of local trout!

Then there's this "head-banging zombie caterpillar" brainwashed by wasps.

After being stung by a parasitic wasp, this caterpillar becomes a body guard: Here it is beating off a curious weevil to protect the cocoons of the very insect that is devouring it from inside. So, in a way, the caterpillar and cricket are no longer their original selves.

It's like the cricket and the caterpillar have become extensions of the minds of their parasitic conquerors...

Parasites even control group behavior. Tapeworm-infected sea monkeys turn bright red and swim together in clumps.

Why? So they can be more easily spotted and eaten by flamingos, which — you guessed it — is exactly where those tapeworms like to breed.

You want to take solace that this is just a thing of the creepy insect world, right?

A parasite called "toxo" has crossed the arthopod-mammal barrier without a problem.

"Toxo" is a one-celled parasite that lives in rats but needs to be inside cats to reproduce. And yes, this is why people are advised to avoid changing litter boxes while they're pregnant.

See, in rats, this toxo manipulates their brains in a way that makes them think it's a smart idea to run toward the smell of cat pee instead of away from it, making the rats easier for cats to hunt.

But if a pregnant person encounters a toxo while cleaning out the litter box of an infected cat, it can cause serious birth defects to the fetus.

It's just not natural!

Except — it is.

It turns out that 1 in 3 of us humans actually have this toxo in our own brains.

Scientists are very divided over whether the parasite is actually manipulating human behavior. Some think they see it in personality tests, car accidents, and schizophrenia.

Bottom line, manipulation in nature is far more common than we've thought. The walking living dead are out there, and there are a lot of them.

Parasite mind control is just one more example of how the natural world is endlessly fascinating.

We should never think we got it all figured out! Unless we're this guy, who sure seems to know a lot about it:

Dad camping with his kids shared the handwritten note left on his car from a fellow camper

More of this, please.

A dad got a sweet note from a fellow father after camping with his kids.

One of the hardest parts of being a parent is never being sure whether you're doing a good job or totally bombing it. If you're conscientious enough to even wonder if you're a good parent, you probably are, but parenting entails a million little choices and interactions, and there's always a lingering voice in your head saying, "What if you're really screwing this whole thing up?"

Reassurance and encouragement are always appreciated by parents, but not always received, which is why a note from one camping dad to another has people celebrating the kindness of anonymous strangers.

"You are killing it as a dad."

Someone on Yosemite Reddit thread shared a photo of a handwritten note with the caption, "To the man who left this thoughtful note on my windshield at Lower Pines Campground this weekend, I extend my heartfelt gratitude; your acknowledgment of my efforts to be a good father means a great deal to me."


Windshield Note.
byu/RCampR6 inYosemite

The note reads:

"Bro,

I camped in the spot behind you last night. Let me just say, you are killing it as a dad. First off, I watched your wife guide you in as you backed up your trailer and nailed it on the first try without any yelling. Then your kids unloaded from the truck and were mild-mannered and well behaved. You told stories around the campfire and I had the pleasure of listening to the sounds of giggles and laughter.

From one dad to another, you are killing it. Keep it up.

P.S. Whatever you cooked for dinner smelled delicious!"

How often do we share these thoughts with strangers, even if we have them? And who wouldn't love to get a surprise bit of praise with specific examples of things we did right?

Everyone needs to hear a compliment once in a while.

So many people found the note to be a breath of fresh air and a good reminder to compliment people when we feel the urge:

"That would make any daddy's eyes water."

"It’s always nice, as a guy, to get a compliment."

"I complimented a guy's glasses at work (I'm also a guy, and btw they were really cool glasses, I wasn't just being nice) and now he keeps trying to tell me where he got his glasses and how I should get some. But I'm just having to be polite because I already have glasses and I'm not in the market. I finally had to tell him I'm not going to buy them lmao I just like them on him.

Made me feel like that's the first compliment he's had in years because he can't stop talking about it. Also I mainly liked the glasses because I think he's cute but he really thinks it's just the glasses haha jokes on him that cute bastard."

via GIPHY

"I was in the store with my wife and one of our 'adopted nephews' yesterday (we’re close friends with his parents and we’ve known him and his brother since they were newborns and 2yo, respectively). A woman came up to me at checkout while my wife was running out to the car and said 'I’m not sure what your family relationship is here, but I just have to tell you how nice and refreshing it is to hear all the laughter and joy from the 3 of you. You both seem like such a good influence on him and it warms my heart.' It’s such a small thing but as a dude, I can’t remember the last time someone gave me a compliment in public and it made my freaking day."

"10/10 letter. The and not yelling part gave me a good chuckle lol."

"We need so much more of men getting such heartfelt and sincere compliments. Thanks for sharing. ❤️"

"I’ve never considered leaving a note, but when I see a harmonious family with good parenting, it’s healing for me. My childhood was awful."

"Such an awesome compliment! Even though I don't have children myself, I like to remind my friends too that they're doing great & it brings them happy tears."

via GIPHY

"This made me cry. I love that you are getting your 'flowers.' My dad sucked, I’m so glad you are one of the good ones."

"This made me cry too. It’s so hard to be a human. Let alone a parent. Getting a good job sticker every now and then really means a lot these days."

"I'm a big bearded guy and I would cry if I got this note. More people like this, please."

The best part of this story is that no one knows who the dad who wrote the note is, not even the dad who shared it. It wasn't written for clout or notoriety, it wasn't to get attention or make himself look good. No name or signature, just an anonymous act of kindness to uplift a stranger whether he needed it or not.

We all need to hear or read kind things said about us, and sometimes it means even more coming from an anonymous stranger who has nothing to gain by sharing. A good reminder to share it when you feel it—you never know how many people you may move and inspire.

Adorable 'Haka baby' dance offers a sweet window into Maori culture

Stop what you're doing and let this awesomeness wash over you.

@focuswithdan/TikTok

A young Māori performing his haka dance.

If you've never seen a Māori haka performed, you're missing out.

The Māori are the indigenous peoples of New Zealand, and their language and customs are an integral part of the island nation. One of the most recognizable Māori traditions outside of New Zealand is the haka, a ceremonial dance or challenge usually performed in a group. The haka represents the pride, strength, and unity of a tribe and is characterized by foot-stamping, body slapping, tongue protrusions, and rhythmic chanting.

Haka is performed at weddings as a sign of reverence and respect for the bride and groom, at funerals, at other significant events, and are also frequently seen before sports competitions, such as rugby matches.

The intensity of the haka is the point. It is meant to be a show of strength and elicit a strong response—which makes seeing a tiny toddler learning to do it all the more adorable.

Here's an example of a rugby haka:

Danny Heke, who goes by @focuswithdan on TikTok, shared a video of a baby learning haka and omigosh it is seriously the most adorable thing. When you see most haka, the dancers aren't smiling—their faces are fierce—so this wee one starting off with an infectious grin is just too much. You can see that he's already getting the moves down, facial expressions and all, though.

As cute as this video is, it's part of a larger effort by Heke to use his TikTok channel to share and promote Māori culture. His videos cover everything from the Te Reo Māori language to traditional practices to issues of prejudice Māori people face.

Here he briefly goes over the different body parts that make up haka:

This one shares a demonstration and explanation of the taiaha, a traditional Māori weapon.

For another taste of haka, check out this video from a school graduation:

Heke even has some fun with the trolls and racists in the comments who try to tell him his culture is dead (what?).

@focuswithdan Credit to you all my AMAZING FOLLOWERS! #focuswithdan #maori #māori #followers #fyp #trolls ♬ original sound - sounds for slomo_bro!

Unfortunately, it's not just ignorant commenters who spew racist bile. A radio interview clip that aired recently called Māori people "genetically predisposed to crime, alcohol, and underperformance," among other terrible things. (The host, a former mayor of Auckland, has been let go for going along with and contributing to the caller's racist narrative.)

@focuswithdan #newzealand radio in 2021 delivering racist commentaries 🤦🏽‍♂️ #māori #maori #focuswithdan #racism DC: @call.me.lettie2.0 ♬ original sound - luna the unicow

That clip highlights why what Heke is sharing is so important. The whole world is enriched when Indigenous people like the Māori have their voices heard and their culture celebrated. The more we learn from each other and our diverse ways of life, the more enjoyable life on Earth will be and the better we'll get at collaborating to confront the challenges we all share.

Eye-opening video shows why 80 percent of Americans live east of this line

You'll never see the U.S. the same again.

via YouTube/RealLifeLore

There's a big change at the 98th meridian.

Have you ever wondered why the eastern half of the United States is densely populated while everything west of Omaha, save for a few metro areas, is no man’s land?

Most people would assume that it’s because people first settled in the east and moved west. Or, they may believe it’s because of the vast desert that takes up most of the southwest. Those are some decent reasons, but it’s a much more complicated issue than you'd imagine.

A 20-minute video by RealLifeLore explains how topography and rainfall have created what appears to be a straight line down the middle of the country on the 98th meridian that dictates population density. Eighty percent of Americans live on the east side of the line and just twenty percent to the west.

RealLifeLore is a YouTube channel that focuses on geography and topography created by Joseph Pisenti.

In the video, we see that several large cities border the American frontier—San Antonio, Austin, Fort Worth, Oklahoma City, Wichita, Omaha, Lincoln, Sioux Falls, and Fargo, as well as Winnipeg up in Canada. To the west of those cities? Not much until you reach western California and the Pacific Northwest.

Why? Watch:

The major reason why the population drastically changes is rainfall. It rains much more on the east side of the line versus the west. The reason for the drastic change in rainfall is that the Rocky Mountains create a colossal wall known as a rain shadow that prevents moisture from passing from the Pacific Ocean. This has created a large swath of dry land that’s not conducive to larger populations.

Though the eastern U.S. is more densely populated, it doesn't mean the west doesn't sometimes feel crowded, especially if you live in Los Angeles County. What side of the line are you on?

A 9-year-old goes in on standardized tests and ends with the best mic drop of all time

When 9-year-old Sydney Smoot stood up at her local school board meeting, I doubt they expected this kind of talking to.

If you need proof standardized testing is setting students up for failure, just ask the students.

Sydney Smoot has a bone to pick with the Hernando County School Board. The issue? The Florida Standards Assessment Test, or FSA for short. On March 17, 2015, Sydney bravely stood up at her local school board meeting to share how she felt about the test and why she believes it's failing students and teachers.

"This testing looks at me as a number. One test defines me as either a failure or a success through a numbered rubric. One test at the end of the year that the teacher or myself will not even see the grade until after the school year is already over. I do not feel that all this FSA testing is accurate to tell how successful I am. It doesn't take in account all of my knowledge and abilities, just a small percentage." — Sydney Smoot

Can we give this little girl a medal? She was speaking right to my soul with that speech!


I reached out to Sydney and her mom, Jennifer, via email to find out more about what prompted this passionate speech.

What inspired you to write your letter?

"What inspired me to speak all started one day when I came home. My mom asked me how the testing went, and I told her I was told not to speak about the test to anyone. I had not felt comfortable signing something in the test. I had concerns about this test because there was a lot of stress put on students and myself. I was a little nervous before the speech, but when I was called up to the podium, I did not feel nervous because I knew this speech was going to help a lot of people."

Have you ever thought about running for president? Cause I'd vote for you!

"I've thought about running for president because if I'm president, I will be considerate about the people in this state."

You gotta admit, she looks pretty good up there, right?

Parents have a right to be concerned about standardize testing regulations.

One thing that really stuck out to me in Sydney's speech was that the FSA prohibits students from talking to their parents about the test. So I was anxious to hear what Sydney's mom thought about the stipulation. She had this to say:

"When my daughter came home telling me she had to sign a form stating she couldn't talk to anyone including her parents, I got concerned. Not only that I didn't like the fact that the last four of her Social Security number was on the test labels along with other personal information. In today's world of identity theft, it doesn't take much for people to get a hold of these things and use them.

I would like to tell other parents to learn more before these tests start in your children's school and know what they are testing. They have options, you can opt out so to speak, and the child can complete alternative testing if they are in the retention grades; or, if the child wants to take the test, support them and let them know that no matter how they do, it does not define them as a person.

It's a test and a poorly designed one at best."

Standardized tests are changing the classroom. And not for the better.

As Sydney shared in her speech, she and her classmates are feeling the pressure when it comes to preparing for the FSA. But they aren't the only ones. Teachers are also struggling to get students ready and are often forced to cut corners as a result.

What standardized tests also fail to take into account is that in many ways, test-taking is a skill, one that not every student is ready for. When I was in school, we spent months gearing up for the dreaded FCAT, the Florida Comprehensive Assessment Test. And if months of test prep wasn't bad enough, if you didn't pass the FCAT, you couldn't graduate high school. Talk about stressful! The pressure of your high school career rides on one test, combined with the fact that standardized tests don't accurately measure what students have learned. Plenty of capable students fail these tests due to increased anxiety and stress. If high school students are struggling to handle the pressure of standardized testing, imagine how difficult it must be for elementary school students like Sydney!

Young Sydney is a testament to how important it is that we listen to students and create curriculum that challenges and educates them, rather than scaring them into "learning." I think Sydney's suggestion of three comprehensive tests throughout the year makes way more sense than one big statewide test that interferes with teachers' schedules and stresses students out. And let's be real, when's the last time you heard a kid ask for MORE tests?! Clearly standardized tests aren't the answer or at least need some serious work. Hopefully Sydney's message will make an impact and get her school board and schools across the nation to rethink how we measure students' success.
