A net-zero future is possible, but first we need to flip a mental switch to truly understand that we can stop the climate crisis if we try, says Nobel laureate Al Gore. In this inspiring and essential talk, Gore shares examples of...

When you poop sugar, clone yourself and give birth to pregnant babies, you know your survival skills are off the hook...and that you must be an aphid.

A puzzle involving colliding blocks where the number pi, vey unexpectedly, shows up.

Top climate scientist James Hansen tells the story of his involvement in the science of and debate over global climate change. In doing so he outlines the overwhelming evidence that change is happening and why that makes him deeply...

Aphids can reproduce incredibly fast: they can make 20 new generations within a single season. And that means lots of poop. Some aphid populations can produce hundreds of kilograms of poop per acre— making them some of the most prolific...

You've probably heard that carbon dioxide is warming the Earth. But how exactly is it doing it? Lieven Scheire uses a rainbow, a light bulb and a bit of quantum physics to describe the science behind global warming.

The tiny atoms that make up our world are made up of even tinier protons, neutrons and electrons. Though the number of protons determines an atom's identity, it's the electrons -- specifically, their exact location outside the nucleus --...

Unlike most living things, there are species of bacteria that can harness electrons directly and even shuttle them around from place to place like living wires.

You've probably known OF E=mc_ since you were born, and were also probably told that it meant that it proved Mass equaled Energy, or something along those lines. BUT WAIT. Was E=mc_ explained to you properly? Mass equalling energy is...

SciShow’s Executive producer Hank Green faces off against SciShow senior editor Alyssa Lerner in this Quiz Show about weird experiments and strange animal parts.

How much more damage do we have to endure before we realize that it's cheaper to save this planet than to ruin it? asks engineer and investor John Doerr. In conversation with Countdown cofounder Lindsay Levin, Doerr and systems innovator...

What if every light bulb in the world could also transmit data? At TEDGlobal, Harald Haas demonstrates, for the first time, a device that could do exactly that. By flickering the light from a single LED, a change too quick for the human...

Venice is sinking. To save it, Rachel Armstrong says we need to outgrow architecture made of inert materials and, well, make architecture that grows itself. She proposes a not-quite-alive material that does its own repairs and sequesters...

In which Stan Muller subs for John Green and teaches you about energy and humanity. Today we discuss the ideas put forth by Alfred Crosby in his book, Children of the Sun. Historically, almost all of the energy that humans use has been...

It's moments after the Big Bang and you're still reeling. You're a particle of matter, amidst a chaotic stew of forces, fusion, and annihilation. If you're lucky and avoid being destroyed by antimatter, you'll be the seed of a future...

Chimpanzees and bonobos may be very close to us humans on the tree of life, but one of our differences is the way we store fat. That difference comes down to types of fat cells and our DNA.

Nuclear weapons are the most destructive things we’ve ever created, but it turns out there’s a way to make them even deadlier…

Remember that episode we did on Australia’s Pink Lake? Well, we have a follow-up! Hank explains in this episode of SciShow News.

In 2020, China's President Xi Jinping pledged that China would both peak its emissions by 2030 and achieve net-zero emissions by 2060 -- a change that will require action at an unheard-of scale and speed. Can the country actually achieve...

In 1947, explorers noticed a strange phenomenon while crossing the Pacific Ocean. Somehow, small squid known to live deep beneath the waves kept appearing on the roof of their boat. The crew was mystified— until they saw the squids...

The energy in the universe never increases or decreases -- but it does move around a lot. Energy can be potential (like a stretched-out rubber band waiting to snap) or kinetic (like the molecules that vibrate within any substance). And...

To hopefully put your mind more at ease, Hank is here to talk about the work that goes into designing and building ICBMs.

On remote, rocky North Pacific islands, you may find a cute little bird that just so happens to smell like tangerines.
