People Share The Scariest Science Facts They Know

#1

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

#2

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 s***ide and fall off so that the damaged DNA doesn’t produce cancer. I’ll never be mad at my skin peeling again.

#3

I don’t think this is scary, but some tin-foil-hat types might.

The frequency range that 5G utilizes is the shared with the C-Band frequency range, which commercial satellites have been utilizing for the past 50+ years. If 5G frequencies do anything to humans (They do not) then they have been doing it on a global scale for decades.

Homeopathy does not work and it’s only proven effects derive from the so-called placebo effect.

Reverting global warming does not unmelt the south pole.

Antarctica is a giant ice mountain (size of US+Canada, average 1km thick) on top of land that is studded by plates of ice in the sea. Think of a very slow moving pudding held in place by a little edge.
All the modeling suggests that once you lose those plates, eventually all the ice will slide into the water.

To refreeze the plates once they are gone, you need an ice age of about -2C to preindustrial, or -3C to current.

There is a 70m of sea level rise of ice on the south pole. The models swing widely on how long it takes to melt on a bunch of factors, but it could be less than 2 centuries for the first 10m.

So either we geoengineer to cool at least the south pole by a tremendous amount, or to hold the ice in place, or in time all coastal regions are lost.
The plates are still in place, but the warmest one is showing signs of stress and thinning. It is linked to 7m of sea level rise if it fails.

To me this is more threatening than any other climate change catastrophe.

If you’re exposed to rabies and start to show symptoms, your chance of survival is virtually zero percent.

#7

Blue whale fart bubbles are big enough to hold a racehorse.

#8

All onions (all veggies in the Allium family) are toxic to dogs. Worst senario then can develop is AIHA, Auto immune hemolytic annemia, whereas the body destroys its own red blood cells. This disease is about 80% fatal. My dog caught it (we are not sure from where) but is was a primary disease (not a result of a cancer). We think he was eating leeks out of the garden. Took a week in the hospital, 2 blood transfusions, and about 6 months of meds to get him back. He started at 45lbs and was down to 19lbs at the worst part of it.

#9

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.

#10

Microplastics in the food and water supplies are crossing the blood/brain barrier.

#11

Antimicrobial Resistance

The bacteria are getting resistant to the medicine much faster than the rate at which we are producing new medicine.

Soon we will reach a scenario when antibiotics cannot treat simple yet lethal infections.

#12

Brain aneurisms can be completely unpredictable and can happen at anytime in your life no matter how healthy you are. A kid who I went to high school with at the age of 16 just did not wake up one morning and his cause of death was a brain aneurism.
