We've been hearing about self-driving cars for years, but autonomous vehicle entrepreneur Aicha Evans thinks we need to dream more daringly. In this exciting talk, she introduces us to robotaxis: fully autonomous, eco-friendly shuttles...

Bacon and eggs aren’t a classic flavor combo for no reason, and the science behind why they taste so good together could help us make healthier foods more appealing to our palates.

Researchers have discovered an underground, liquid water lake on Mars! What might it be like, and why did it take us so long to find it?

This week, researchers are getting ready to learn about earth and Mars, in places that you might not expect.

It's virtually impossible to tell where a meteorite comes from, but in 2018, scientists were able to pull a feat of forensic astronomy and do just that.

A new telescope, the DKIST, has given us our most direct look at the Sun ever, in the highest resolution yet. And a paper published last week has revealed how “the dunes” auroras may be more than just a new spectacle in the night sky.

Most rocky planets have pretty consistent surface features, with a fairly even mix of mountains and basins in each hemisphere. This is NOT the case on Mars! What do scientists know about this mystery?

Climate doom-ism, or a pessimistic outlook on the future of the planet, rivals climate denialism in holding up the fight against climate change, says activist Zahra Biabani. Illuminating how hope combats inaction, she takes us inside the...

Salmon make a hardcore journey upstream to their spawning grounds to reproduce, and it almost always ends with death. But some live to reproduce again, and more than once!

Space is hard on the human body, but a certain ground squirrel might have the guts to show us how to last longer in space.

Thanks to some amazing scientific insights, we know a lot about the interior of our planet - even though we’ve never even made it through the crust.

Hank brings us the story of Elizabeth Blackburn, the Nobel Prize-winning Australian woman who discovered telomeres and telomerase, and helped scientists begin to understand the process of aging at a genetic level.

In a fun, exciting talk, teenager Henry Lin looks at something unexpected in the sky: distant galaxy clusters. By studying the properties of the universe's largest pieces, says the Intel Science Fair award winner, we can learn quite a...

What’s irrational and never ends? Pi! Hank explains how we need pi to explain some of the most basic but most important principles of the universe, in honor of Pi Day.

Astronomers have found more evidence for Planet 9, but another study has added another problem to our list of space travel problems.

We’ve seen a distant star from another galaxy far, far away, and the Milky Way is growing, thanks to baby stars born in the outer edge of our galaxy’s disk.

In 2026, an unmanned NASA spacecraft is scheduled to arrive at 16 Psyche, a massive, metallic asteroid floating somewhere between the orbits of Mars and Jupiter. Why is NASA so interested in this heavy metal asteroid? Are we going to...

Sometimes, studying uncommon maladies can reveal larger insights into how our bodies work!<br/>

Science can help create understanding where there is none, but is it possible to study and understand terrorists if we're too busy doing everything we can to stop it? Terrorism is notoriously difficult to study because governments...

Who wants to be a biologist? Learn all about scientists who study life -- like where they do their jobs, the questions they ask, and the tools they use!

Hybrid organisms are rare, and most end up sterile, like mules. But sometimes, three or more species come together to create multi-species hybrids, and they can and have been really useful.

If you're anything like us, you're always investigating and asking questions about the world around you! Keeping a field journal is a great way to keep track of all the ideas and observations you have every day!

The search began with a physicist checking for sources of static on phone calls in the 1930s, but it took several decades to finally make one of the biggest discoveries in astronomy, Sagittarius A*.

More than half of all the matter in the universe is out in the dark, 'empty space.' Although it's basically invisible, the intergalactic medium has a lot to tell us about the stuff we can see.
