Why Don’t Humans Have a Penis Bone?

Why Don’t Humans Have a Penis Bone?

There are 206 bones in the human body, and yes, it’s the same for men and women. No, women don’t have fewer ribs than men, and men don’t have one extra bone, if you know what I mean. You know what I mean. But several mammals, including our close relatives like chimpanzees, do have that

Will We Ever Be Able to Travel Through a Wormhole?

Will We Ever Be Able to Travel Through a Wormhole?

What happens when you have two black holes, quantum particles and a hell of a lot of gravity all in one place!? Traversable wormholes!! AKA a time machine? Many of you guys might’ve seen this demo of how a wormhole works. So if you have two points on a piece of paper… Like two planets

Quantum Computers Are Making Classical Ones Faster, Here’s How

Quantum Computers Are Making Classical Ones Faster, Here’s How

Quantum computers promise to one day dominate their classical counterparts like the computers we use today. But classical computers will not go gentle into that good night. They’re fighting inevitable quantum supremacy, and they’re using some tricks they’ve picked up thanks to quantum computers. You’re probably familiar with how classical computers work, information is broken

What Is the Shape of the Universe?

What Is the Shape of the Universe?

It’s the kind of question that sort of breaks your brain when you even start to figure out how to think about it: what shape is the universe? No one can be sure; until we can step outside of the universe and walk around it somehow — we can’t actually do that ever — the

Will We Ever Time Travel? Scientists Say ‘No’ Based on This New Discovery

Will We Ever Time Travel? Scientists Say ‘No’ Based on This New Discovery

So, this is probably what you think of when you picture an atom, right? The thing is, the central part of this model is just plain inaccurate. Scientists recently found the nucleus of some atoms don’t look like this at all, and it’s causing a ruckus because well, this newfound shape straight up shouldn’t exist.

Why Severe Winter STILL Doesn’t Disprove Global Warming

Why Severe Winter STILL Doesn’t Disprove Global Warming

Sometimes it’s cold out. In fact, this 2017-18 winter is breaking RECORDS for how cold it’s been! The last year has seen over 10 and a half thousand low temperature records broken. Prompting many to ask, is global warming even real? I CAN SEE MY BREATH! If you’re one of the many who question global

These Liquid-Repelling Materials Defy Nature’s Design, Here’s How

These Liquid-Repelling Materials Defy Nature’s Design, Here’s How

I remember watching this video online and being mesmerized. The more liquid they spilled on the items the more I thought “how was this even working?, what’s going on here?” This is a superhydrophobic coating with properties that are seemingly impossible. But this material science field is making some exciting developments with materials that are

China’s Superintense Laser Could Create Matter From Energy

China’s Superintense Laser Could Create Matter From Energy

E=mc2, energy is equal to mass times the speed of light squared. We’ve demonstrated this to dramatic effect with nuclear bombs, converting a little mass into a lot of energy, but we’ve never done it the other way around and turned energy into mass. At least we haven’t done it… yet. When you think high

Hi everyone, Dr. Ali Mattu here. Recently the awesome people at D News invited me to come over and make some science videos together! On TestTube Plus, Trace Dominguez and I explored how to overcome anxiety. I partnered with D News’s Julia Wilde to explain hair-pulling disorder. And I managed to squeeze in an episode

You’re Too Clean, and It’s Messing With Your Immune System

You’re Too Clean, and It’s Messing With Your Immune System

Washing your hands may be the best way to keep from getting sick, but in some ways, DIRT does a body good. We’ve all been taught that dirt is bad for us. In my Grandmother’s house “Cleanliness was next to Godliness” and everything was scrubbed clean and disinfected, but now with new research on the
