Two astronauts are about to embark on the One Year Mission which can help us understand more about the long-term effects of being in space, and there is an upcoming total lunar eclipse (the shortest one this century)!

Love is a complicated combination of brain chemicals and behavior that scientists are only just beginning to figure out. And it's remarkable that in every society that we have looked at on Earth, romantic love exists. So if love is so...

A skyrocketing demand for food means that agriculture has become the largest driver of climate change, biodiversity loss and environmental destruction. Jonathan Foley shows why we desperately need to begin "terraculture" -- farming for...

Suppose you placed a camera at a fixed position, took a picture of the sky at the same time every day for an entire year, and overlaid all of the photos on top of each other. What would the sun look like in that combined image? A...

A new detector can use neutrinos to help us take a peek inside Earth, and a study of jellyfish galaxies can help us understand more about an unsolved problem in astronomy.

The True Science of Parallel Universes

What gives the ocean its distinct, sometimes pungent smell? It turns out the answer is more than just dead fish or salt: it’s the scent of tons of phytoplankton being munched on!

Want to get your sweetheart something really special? Give them a mineral called fingerite, and then stare at them for a while! Find out why, in this Valentine's Day edition of SciShow News.

These days it seems almost trivial to cool atoms down to near absolute zero temperatures in a lab, but what is the lowest possible naturally occurring air temperature on this planet?

Scientific discovery often dabbles in the extreme, challenging and exceeding what we think of as "possible." And this year's discoveries were no different! We present to you three scientific discoveries made this year that set out to...

3 Ways to Prevent Hurricanes (Maybe)

On a cosmic scale, Mercury isn’t very far away, but it's incredibly hard to get there. Getting into orbit around it takes years of flybys in the solar system, but we're going to do it again!

Have you ever noticed that warning about raw or undercooked seafood at the bottom of restaurant menus? Ever wondered why it's there? Because fish carry a ton of parasites, and if they aren't prepared correctly then those parasites can...

Space, also known as The Final Frontier, has been in our collective dreams and fantasies for decades. Who WOULDN'T want to blast into space, experience zero gravity, or walk on the moon?! But with limited funding to NASA, the day that...

Elon Musk's SpaceX program proposes that 100 people could be sent to colonize Mars within 10 years. What might that colony look like?

Asteroid strikes get all the coverage, but "Medea Hypothesis" author Peter Ward argues that most of Earth's mass extinctions were caused by lowly bacteria. The culprit, a poison called hydrogen sulfide, may have an interesting...

Days before this talk, journalist Naomi Klein was on a boat in the Gulf of Mexico, looking at the catastrophic results of BP's risky pursuit of oil. Our societies have become addicted to extreme risk in finding new energy, new financial...

This year, science news has understandably focused a lot on COVID-19. But other science has carried on, and there have been plenty of amazing discoveries this year that we think deserve a spotlight, too!

Cicadas have developed an amazing strategy for growth, survival, reproduction, and overcoming predation by...doing nothing. They do nothing for years (except sip at the juice excreted from root structures) before emerging in huge,...

Earlier today, mission specialists with NASA's Mars Science Laboratory announced that they have found, for the first time, evidence of an ancient environment on Mars that could have sustained life. Hank tells us the specifics in this...

Tech enthusiast Kevin Kelly asks "What does technology want?" and discovers that its movement toward ubiquity and complexity is much like the evolution of life.

We have been studying our home galaxy for years, but even though astronomy has come a long way, there is still a lot we don't know about the Milky Way.

Imagine being excited to use one of the world's most advanced telescopes, only to see bright streaks of light on every picture! This is a problem facing some astronomers as satellites fill up the night sky.

Jessi and Squeaks explore nature’s way of letting off a little steam.
