Did you know that most of the scientific community agrees we are in the middle of a mass extinction right now? We are currently in the middle of the sixth extinction.

If you want to learn more about this, I highly recommend The Sixth Extinction: An Unnatural History, which analyzes mass extinction events and argues why we are dealing with one as we speak. It was a bestseller, by the way, and it won a Pulitzer Prize.

But there's a wealth of scary facts out there... is knowledge necessarily power?

We'll get back to you on that.

People shared their thoughts after Redditor Lioniz asked the online community:

"What's a scary science fact that the public knows nothing about?"

"Insect population..."

"50% of insects have disappeared since 1970. Insect population is down 27% in the last 30 years. Declining between 1 and 4% each year depending on the genus."


This is true, and it's unnerving many scientists as we continue to deal with the effects of climate change and habitat loss.

"Heart muscle cells..."

"Heart muscle cells don’t reproduce much in adults (roughly 1% per year). If you have an infarction or other stressor that kills those cells, then your heart wont be able to “grow” new cells to replace the dead ones."

"This is why patients with diseases like heart failure end up needing a heart transplant. Trying to get this process to happen is a major goal for many cardiac researchers."


This is fascinating.

Hopefully one day scientists can figure this out.

"Anthrax spores..."

"Anthrax spores can remain viable for decades in the soil or animal products such as dried or processed hides and wool."


The paranoia this instilled... I think I'm going to fall down a black hole reading more about this later.

"When doing an autopsy..."

"When doing an autopsy they don’t put the organs back where they belong, they are all stored in the belly."


I mean, this makes sense to me.

It's more convenient, isn't it?

"Scientists don't exactly know..."

"Scientists don't know exactly how Acetaminophen works to relieve pain and reduce fever. They have an idea but nothing for sure. But yet it's the most commonly used pain reliever in the world."

Have you ever worked one of those jobs that paid you to kinda sit there? If you have, you know the joy that comes with watching the entirety of Breaking Bad ...

This is indeed true!

A few scientists have posited that it might have something to do with chemical messengers of inflammation and pain, but that's just one suggested explanation and there isn't a straight answer just yet.

"Trauma can cause..."

"Trauma can cause structural changes to your brain. PTSD is literally an injury."


It is indeed.

Mental health should be a top priority.

Thankfully, much has changed in the way society treats it and responds to it.

"I only recently..."

"I only recently learned that when you get sunburned, the burn isn’t because of skin cell damage. The UV radiation damages the DNA. Then the skin cells decide to commit suicide and fall off so that the damaged DNA doesn’t produce cancer. I’ll never be mad at my skin peeling again."


I had a bad sunburn a few months back and learned about this.

I upped my sunscreen game.

"Approximately 60%..."

"Approximately 60% (in some reports) of the world's population have the parasite toxoplasma gondii in their brain. For a long time it's thought to have been a benign presence, but recent statistical research shows that it may have an impact on things like levels of anger and rates of accidents and suicide."


Another thing I'll read about at three in the morning to creep myself out, thanks.

"If your dog..."

"If your dog swims in a lake after receiving a spot on flea treatment - it absolutely decimates the invertibrate population."


That's wild!

Keep an eye on your pets, everyone.

The world in which we live is vast and incredible. There's still so much we do not know, but who knows?

Perhaps one day scientists will have the answers to the questions that continue to perplex us. All we can do is wait.

Turns out not all of us are interested in being benevolent Gods.

It's Reddit, so we're not exactly surprised, but we're suddenly glad divine cosmic powers don't work this way.

Are you like me and the 1990s were only 10 years ago?

Yes, I can do the math, but 1990 being 32 years ago still seems unreal.

Why is that?

Maybe it's the fact it marked the end of the 20th century and beginning of the 21st.

Either way, it just doesn't seem that long ago and the nostalgia for the trappings of the 1990s is strong.

You're probably going to be beat over the head with this as you read this charming article but bedbugs are a nightmare and they are always lurking (in the back of my mind) when I think about purchasing some items secondhand.

Some years ago, a relative brought in a stuffed animal and some other items off the street. Within days we had a bedbug issue.

It was thankfully resolved very quickly–good thing it was caught so early–but let's just say I dealt with phantom itch for a while.

Nooo thank you.
