There’s more to DNA than just the double helix we know and love: under some conditions this familiar molecule can take on unfamiliar forms, each of which can have a different impact on our health.

In a robot lab at TEDGlobal, Raffaello D'Andrea demos his flying quadcopters: robots that think like athletes, solving physical problems with algorithms that help them learn. In a series of nifty demos, D'Andrea show drones that play...

We all know ducks quack, dogs bark, and birds chirp, but that barely scratches the surface of all the amazing ways animals have devised to talk to each other!

Hank brings you the facts, as they are understood by scientists today, about the evolution of humans from our humble primate ancestors. On the way to becoming Homo sapiens, game-changing evolutionary breakthroughs led to the development...

This week, Emily Graslie is teaching you about human ancestry and geneaology, how we got to be the species we are, and why that matters in our zoomed out look at Big History.

This Valentine’s Day weekend, we'd like to tell you a deep-sea shrimp love story that begins with a sponge, and two shrimp — and ends in forever.

Sound can't actually travel through a vacuum like space, but scientists have learned that there's still plenty to hear.

We've made some great strides in understanding the human genome, but before we can tackle genetic engineering, we have some "chicken and egg" problems to figure out.

Everyone loves slime... until it starts coming out of someone's nose, then all of a sudden it's "gross." But this slimy stuff is also really important to the lives of many animals, including humans!

The actual path of a raindrop as it goes down the valley is unpredictable, but the general direction is inevitable, says digital visionary Kevin Kelly -- and technology is much the same, driven by patterns that are surprising but...

In this episode of SciShow we look at the most fascinating birds that hover!

What is genomics? How will it affect our lives? In this intriguing primer on the genomics revolution, entrepreneur Barry Schuler says we can at least expect healthier, tastier food. He suggests we start with the pinot noir grape, to...

What if we could use biology to restore our balance with nature without giving up modern creature comforts? Advocating for a new kind of environmentalism, scientist and entrepreneur Emily Leproust rethinks modern sustainability at the...

If we hope to one day leave Earth and explore the universe, our bodies are going to have to get a lot better at surviving the harsh conditions of space. Using synthetic biology, Lisa Nip hopes to harness special powers from microbes on...

Insects and animals have evolved some amazing skills -- but, as Robert Full notes, many animals are actually over-engineered. The trick is to copy only what's necessary. He shows how human engineers can learn from animals' tricks.

It’s so easy to forgive a dog, especially when they start with those puppy dog eyes. As it turns out, those puppy dog eyes and the effect they have are no accident and the result of centuries of domestication.

As a novelist, Daniel Suarez spins dystopian tales of the future. But on the TEDGlobal stage, he talks us through a real-life scenario we all need to know more about: the rise of autonomous robotic weapons of war. Advanced drones,...

Picture this: you're gorging on leftover Halloween candy. You take a bite of a fun-size chocolate bar and instead of sugary goodness, you get a flash of blinding pain in your tooth! What's the deal?

We were probably all told to quit picking our noses at one point, and by most standards, this is good advice. But if you were a toad, it might come in handy to scratch away blowfly eggs

Chris Abani tells stories of people: People standing up to soldiers. People being compassionate. People being human and reclaiming their humanity. It's "ubuntu," he says: the only way for me to be human is for you to reflect my humanity...

What makes work satisfying? Apart from a paycheck, there are intangible values that, Barry Schwartz suggests, our current way of thinking about work simply ignores. It's time to stop thinking of workers as cogs on a wheel.
