When ITER's tokamak finally comes online (as of July 2024, that's 2034 for its first round of research, and 2039 for deuterium-tritium fusion), it will become the world's biggest fusion reactor. But don't hold your breath for a green...

From steam engines, to contact lenses, to biometric security based on someone's voice, there are a lot of inventions out there that are older than you think.<b<br/>r/>

Today we're talking about the weirdest trees in the world, from the psychedelic rainbow eucalyptus, to the dragon's blood tree, to the jabuticaba that grows delicious fruits on its trunk.<b<br/>r/>

There's a growing trend out there among users of hallucinogenic drugs - microdosing. The idea is to take a tiny dose of these drugs to get certain brain benefits without going all Sergeant Pepper. But does it work? Let's get into what...

The Vikings were renowned navigators at a time before magnetic compasses were invented. So how'd they manage it? Their secret may have been these pretty-pointed crystals of calcite called Iceland spar, and this month's SciShow Rocks...

If you've ever watched a video of someone doing some crazy parkour daredevil stuff, you might have wondered how they're still in the gene pool. But it turns out that all that dangerous behavior may be a pretty good thing after all, and...

Sometimes, an ancient document is lost to history. Sometimes, you find it covered in mold and written over by an ancient scribe. Fortunately, thanks to science, lost doesn't quite mean what it used to.

Do you dream in color? For part of the 20th century, it was so rare, psychologists thought it meant something was wrong with you. For a generation, people dreamed in black and white, and TV might be to blame.

You may have heard that redheads need less pain medicine, or that they need more anesthesia in surgeries. And both of those things are true! Which is weird. Let's talk about some of the stuff we know about what the heck hair color has...

In the history of space travel, there are a few famous animal astronauts (or cosmonauts), like Laika the dog and Ham the chimpanzee. But you might not have heard of Félicette, who in 1963 became the first -- and so far only -- cat to...

Correction: This is Watt's law, not Ohm's law! Our math was right but our name was wrong.



We need green energy yesterday. And it so happens that nature regularly sends huge bolts of electricity at us out of the sky. So what...

When caterpillars undergo metamorphosis and become butterflies, their brains melt into goop. Neuroscience says they shouldn't remember anything about their past lives. So why do studies show that they do?

From hypothetical magnetic levitation trains and space elevators that aren't even attached to the ground, to very real space cannons tested in the 1960s, humans have come up with a lot of ways to hurl stuff into outer...

If you've wandered down a supplement aisle recently, you may have come across a bottle for sale that has "anti-aging" ingredients to help your body make a molecule called NAD+, better known as nicotinamide adenine dinucleotide. Your...

Every day, airplanes fly over the Panama-Colombia border and drop millions of flies from the sky. It's part of an intense effort to control a deadly pest called screwworms, and believe it or not, it works.

In 2020, students from the University of Texas proposed sending a fleet of rovers to the Moon that, for a price, would carve words and symbols into the surface for *you*, random human. And that got us thinking, how big would such a...

This lake in Canada sports a stunning summer look - spots! And the weird geology and hydrology that makes these spots is definitely worth talking about. Plus, Spotted Lake may not be the only one of its kind, and might tell us more...
