Hank and PhD candidate Casey Massena go deep into the chemistry of a molecule that Casey helped create! Then Jessi joins the show to show off Ecuador, one of her many conures!

Musty, with hints of vanilla, coffee, and maybe fresh cut grass-- why do old books smell the best?

Carbon dating transformed fields like archeology and paleontology, but its use might be in danger.

While not used much any more as a primary source of light, candles are still everywhere, from an aroma in a bathroom to a mood during dinner. That is, until they’re gone.

Though we probably won’t find a literal Atlantis beneath the sea, that doesn’t mean that a human settlement hasn’t ever been lost to the water. Meet Doggerland.

2017 has been an eventful year, so as it comes to a close we'd like to look back at some of its most superlative science.

Some might call sand coarse, rough and irritating, but there’s no denying that it’s used everywhere: from glass to asphalt, sand is a key ingredient for all sorts of materials in construction and technology. But this heavy reliance on...

Need a determination boost to complete those New Year's Resolutions (or really any kind of resolution)? Look no further than this compilation of SciShow videos from SciShow of yore. Why Our Brains Love Junk Food - 1:11 3 Terrible...

Hank interviews Administrator Gina McCarthy of the United States Environmental Protection Agency. They discuss getting people to care about climate change, the EPA's goals going into the United Nations Climate Change Conference, and the...

We can see the effects of the climate crisis in many different ways here on land. But the oceans are also part of the interconnected, global system. So, here are a few ways that climate change affects our oceanic buddies.

Sometimes science creates a mystery, and it can be very difficult to solve! Join Hank for a fun new episode of SciShow about five mysteries started and later solved by science. Let's go! Hosted by: Hank Green

Plants have their own interconnected networks that allow them to communicate with each other, sometimes over considerable distances!

It turns out life may have gotten its start pretty early in Earth's history, and while the first couple billion years saw several important developments, the period was still dominated by very simple life forms. This is our first...

From wasps nests to nuclear reactors. Here are just a few clever ways archeologists figure out how old something is.

Photosynthesis plays a huge role in regulating the earth's CO2. But what happens when the temperature gets high enough that photosynthesis slows down?

Who knew that a rainforest could be literal? Hosted by: Rose Bear Don't Walk (she/her)

When Climate Change Threatens Climate Solutions | SciShow News

If we want to better understand the environment and combat climate change, we need to look deep underground, where diverse microscopic fungal networks mingle with tree roots to form symbiotic partnerships, says microbiologist Colin...

How much is one living blue whale worth in the fight against climate change? A lot more than you may think, says financial economist Ralph Chami. He explains the value of bringing the language of dollars and cents to conservation -- and...

In the early 20th century, Alfred Wegener's theory of Continental Drift laid the foundation for our modern theory of plate tectonics. And today we know something even more exciting: Pangea was only the latest in a long lineage of...

In June 2022, a gold miner in the Canadian Yukon made a remarkable discovery. While working on the traditional lands of the Tr'ondëk Hwëch'in First Nation, he uncovered the exceptionally well-preserved, frozen remains of a wooly mammoth...

In this video Paul Andersen explains how atoms are conserved in a chemical reaction. This can be seen in a chemical equation where the subscripts represent the atoms in the molecule and the coefficients represent the molecules. The...

In this video Paul Andersen explains how the conservation of matter can be displayed with both symbolic representations and particulate drawings. A simple conservation of matter problem is also included.

Paul Andersen explains how living organisms exchange matter with the environment. The importance of the surface area to volume ratio is emphasized using a simple mathematical model. The essential chemicals for life; water, carbon,...
