It's barbecue season around the SciShow office, which means applying our knowledge of science to this delicious outdoor past-time.

Thanks to climate change, many regions are experiencing longer and more dangerous wildfire seasons. Here are 4 high-tech ways we are trying to stop these fires in there tracks, as well as one that’s a bit simpler.

We know these glaciers are already on the way out, so we need to find out whether we can bulk them back up again. For that, we turn to the glaciers’ past – and a lot of penguin bones.

Nobody agrees on how many organs you have, or the exact criteria for a cluster of cells to be called one. But as it turns out, simply identifying a part of the body as an organ can lead to medical breakthroughs.

Venomous snakes produce some of the world’s deadliest substances, so they have to be pretty careful about how they use it. But what happens if they accidentally inject themselves with their own harmful cocktail?

It might sound like a concept from science fiction, but artificial intelligence is already facilitating the development process behind some pharmaceuticals. Hosted by: Michael Aranda

This week, scientists have managed to make tear gland organoids that cry, and have also found a bunch of new genes involved in eye color!

We here at SciShow know of two things that can help you get through this flu season: a flu shot, and watching this video. Make sure you do both! Hosted by: Hank Green

Trees are essential to our survival—from making oxygen so we can breathe, to cooling urban environments, to literally holding the ground together to prevent erosion, trees do so much for us!

What is "Long-Covid"? What does it mean? The list of symptoms for “Long COVID” last long after you've healed from the illness. But the more we learn about it, and how it is similar to other post-infection syndromes, the better we can...

If you’ve heard anything about pesticides, it’s probably about how toxic they are. But they make growing food more cost-effective, so when some make it into your groceries, how bad can they be?

Scorpion venom and insect poison sound really deadly, but scientists are increasingly turning them into medical treatments that save millions of lives. Hosted by: Hank Green

You probably don't think much about birds most of the time, but these little former-dinosaurs are amazing! So, here's a collection of videos in which we've tackled our viewers' biggest bird questions!

According to the fossils we've found, it turns out the T-Rex may look different than what we thought! Join Hank Green for a fascinating dive into the past, and a realistic look at what the King of the Dinosaurs was actually like. Let's...

Researchers have made some unexpected readings of mysterious particles called muons, which may make us reexamine the Standard Model in physics.

We began keeping goldfish as pets more than 1,000 years ago, but their beauty wasn’t the only thing they had going for them. Goldfish had a lot of really weird biological traits that made them incredibly resilient. And in an unfortunate...

In which Hank details the five scariest things that will likely happen because of climate change.

You've heard of the battle of the sexes—but these 7 animal species take it pretty seriously. Join Michael Aranda for a new episode of SciShow and learn about these animals with pretty big sex-related disputes.

Usually when you think of evolution or natural selection, you think of survival of the fittest. But sometimes, the resulting traits of evolution aren’t the most efficient solutions to the problems at hand. With the bar set to “good...

We know that lots of animals and plants can be found all over the world. But there's plenty that manage to live at the furthest points from each other they possibly can - and are /still/ the same species. It's called being bipolar, and...

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

Hank makes it all better by explaining the biochemistry of pain -- how it works, why we have it, and how painkillers, whether they're over the counter or heavy-duty prescription bad boys, make the pain go away.

If you ever get nervous about missile attacks, they're actually a lot harder to make than you might think. To hopefully put your mind more at ease, Hank is here to talk about the work that goes into designing and building ICBMs in this...

Is there a chance that more species may actually be closer to fish than we originally thought?
