Are Those Your Lips or Feet? How Your Brain Rewires Itself After Amputation

Even though it looks like a random, bumpy mess, your brain is incredibly organized. Your brain has its own version of google maps for navigating the world around it — but just how flexible are these maps to changes? Every sound you can hear or touch you can feel is because neurons in a specific

We’re Using Stem Cells to Reverse Baldness and It’s Actually Working

We’re Using Stem Cells to Reverse Baldness and It’s Actually Working

Some very hairy mice are bringing us another step closer to un-LOCKing a way to regenerate a full head of hair. Did somebody say a pun?! About 50% of men and 25% of women experience at least partial hair loss by the age of 50, whether due to age, medical treatments, or disease. Current options

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

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.

Photonic Chips Will Change Computing Forever… If We Can Get Them Right

Photonic Chips Will Change Computing Forever… If We Can Get Them Right

The electrons shuffling around inside our computers move pretty fast, theoretically their top speed in silicon is up to 100,000 meters per second. Which is good because the faster they can move, the faster chips can do calculations, the faster I can refresh twitter. But there will always be something faster. Light. Why don’t we

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

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
