Video: The placebo effect is real, we all know that. Our bodies can be tricked into getting better and healthier even when we're take taking sugar pills or fake drugs or undergoing treatment that isn't even supposed to help us get better. If we believe it will help, it sometimes really does help. TED-Ed dives in a bit on the mystery behind the phenomenon. The placebo effect is proof of how extraordinary the human body is but also that it's not always a good thing.

Video: The human body is such a magnificent thing. Just check out this video that shows how our immune system works. When a parasite finds its way inside a place where it clearly shouldn't be, white blood cells immediately start rushing to the rescue. It only takes a few seconds for the parasite to get swallowed.
Something that seems ripped from the future is being developed right now inside a lab in Brooklyn. It's the VetiGel which is also known as the borderline magical band-aid of the future. It's a gel that when applied on a wound, almost immediately stops the bleeding. Here's the lab where they make the future.
It pumps blood. Duh! Well, for most of history, people were unsure what the heart's main function was. Even Leonardo Da Vinci gave up studying it and he's probably one of the five smartest guy ever. Even now, it's not as easy as it should be to find out how the ticker actually works. Don't worry, this Ted-Ed animation will explain it to you perfectly. Basically, if you watch this animation explainer, you'll be smarter than Da Vinci.
It's a pumping lung in a box, basically. Al Jazeera America specifies that its more properly known as the Organ Care System (OCS), but it's basically a human donor lung being kept alive and breathing out of the body inside a box. The OCS machine is used to keep the blood and oxygen flowing to the donor organ so that it can buy itself more time before the donor organ is given to the recipient.
OK, this is the best beer belly any one of us could ever dream of having. A 61-year-old man found himself getting drunk without ever drinking alcohol because he had brewer's yeast in his gut. Basically, whenever he ate any carbs, the man's intestinal tract would start turning that into beer and make him drunk. He had a brewery in his belly.
Women have the ultimate trump card when it comes to dealing with pain: they give birth. And since men have no idea what giving birth even feels like, we really don't know how painful it really is. Maybe it's all a big conspiracy (kidding!). Maybe it's not that bad (of course it is!). Well, two men attached themselves to a machine that simulates labour pains and um, it ain't pretty.
Scientists, bless their brains, have finally tracked the paths of sperm in 3D. It's the first time they've been successful in 3D-mapping the trajectory of sperm and it's revealed a few things about those drippy critters: some sperm swim in corkscrew-like patterns and others are 'hyperactive' and hectic. Your sperm has strokes, dude.
If you're looking for a pair of futuristic glasses that have realistic, earth-shifting implications, check out these frames by 2AI Labs being tested by doctors right now (hmm? not who you were thinking?). They can make your veins glow so nurses can easily spot them, show a change in hemoglobin colour to locate trauma and can be used to monitor how a patient is really feeling.
The ancient Greeks called the thapsia garganica plant "deadly carrot", because their camels would eat it and quickly die. The Roman emperor Nero mixed it with frankincense to treat bruises. Until the early 20th century, it was used in a plaster to treat rheumatism — the side effects, however, were barely worth the cure.
