    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 for those looking to reverse this loss include things like medications that may slow hair loss and transplants from hair follicles elsewhere on the body. But neither have the often desired effect of restoring a thick and full volume of hair. Researchers have been optimizing techniques for culturing “hair follicle germs” in a dish for…

    Your Skin Cells Could Make a Baby, Will This Be the End of Infertility?

    We all know where babies come from. An egg is fertilized by sperm and the resulting zygote needs to be implanted in a uterus so it can grow and divide. The key here is the union of the gametes: sperm and egg. This means same-sex partners, or partners who are unable to provide gametes themselves, need to rely on donors. But what if that wasn’t the case? What if we could just generate gametes from the partners? Soon, we might be able to. The method is called in-vitro gametogenesis. It involves converting adult cells into lab-made eggs and sperm cells that can combine to create a zygote. This could pave…

    DNA Doesn’t Look Like What You Think!

    [PBS Intro] I hate to tell you this, but if you’ve ever looked at a biology textbook, chances are it was lying to you. Or at least not telling you the whole story– about DNA. Today, we’re going to fix that. [OPEN] Real quick, what image comes to mind when I say “DNA”. Have you got it? You’re probably imagining something like this, or this, or maybe this? That’s not what DNA looks like. Of course you can’t exactly take a photograph of DNA, or see it through your typical microscope. It’s simply too small. A double helix of DNA is just 2 nanometers wide. A DNA strand next to…

    Your Body on Carbs

    You’ve probably heard that carbs are bad for you. And there’s a lot of us searching for signs they’re good, possibly sugar, or just the devil. But carbohydrates are your body’s main fuel source. So what do carbs actually DO when they pasta through your body? Carbohydrates in our food fall into three categories: sugars, starches, and dietary fibre. Sugars, like lactose, fructose, and sucrose, can be found in foods like milk, tangerines, and table sugar. Starches and dietary fibre are both long chains of sugars. And when we eat carbs, our saliva and stomach acid break long sugar chains down into short chains. Once the food reaches the intestines,…

    Why Is Blue So Rare In Nature?

    [PBS Bumper] [OPEN] There are no blue tigers. No blue bats, no blue squirrels, or blue dogs. Even blue whales aren’t that blue. Animals come in pretty much every color, but blue seems to be the rarest. What’s cool, though, is when we do find a blue animal, they’re awesome looking. Nature doesn’t do halfway with blue. To understand why this is, we’re gonna journey through evolution, chemistry, and some very cool physics. But, first we’re gonna need to understand why animals are any color at all, and to do that, we need to go look at some butterflies… because butterflies are awesome… and if you don’t think so, you’re…

    6 ways mushrooms can save the world | Paul Stamets

    I love a challenge, and saving the Earth is probably a good one. We all know the Earth is in trouble. We have now entered in the 6X, the sixth major extinction on this planet. I often wondered, if there was a United Organization of Organisms — otherwise known as “Uh-Oh” — (Laughter) — and every organism had a right to vote, would we be voted on the planet, or off the planet? I think that vote is occurring right now. I want to present to you a suite of six mycological solutions, using fungi, and these solutions are based on mycelium. The mycelium infuses all landscapes, it holds soils…
