Most of us can only see certain wavelengths of light our entire lives. So why can salmon switch on night vision? We'll learn how they can reshape their eyes to see into the infrared.

Sponges might not look like particularly complex animals, but they've had billions of years to evolve their own special systems. And one of those systems might involve sending messages through their body in the form of light.

What do a platypus, a pufferfish, and a seahorse have in common? Why, they all managed to evolve themselves out of having a working stomach! The reasons why might vary, as well as how they manage to live their lives without them, but...

How come sharks get to have endlessly regrowing teeth when humans only get one set our entire lives? And how come some other mammals get to cheat the system? From elephants to baboons, we'll learn why teeth don't grow back.

You're lucky you don't literally age faster and drop dead when you see a dead person... because fruit flies do. Here's what researchers are learning about the connection between perception, aging, and mood disorders like depression.

We hear all the time about the ways that climate change could disrupt the world. But thanks to a quirk of reptile biology called temperature-based sex determination, it could also mean a surge in the numbers of female reptiles.

From the long extinct Stegosaurus, to tiny modern mice, all sorts of animals grow bits of bones inside their skin. These structures are called osteoderms, and they're often more than just a suit of armor.

The tree of life you learned in school is wrong, even if you just graduated. We like to sort eukaryotes into big kingdoms or supergroups, but scientists can't agree what those groups should be. Here's why that's a good thing.

If you hear birds chirping in the trees, you might not think much of the different sounds you're hearing. But as it turns out, those tweets and chirps have a lot more in common with some of our complicated rules of grammar than you might...

Months before Apollo 8 took humans around the Moon for the first time, two Russian tortoises (plus some other lunar tourists) had already made it back home. This was Zond 5 — the first mission to return to Earth after visiting another...

For us terrestrial animals, sneezing is a regular part of life involving the movement of a lot of air. But animals that live underwater and don't breathe air like we do also sneeze. Sea sponges, corals, and hagfish use their snot to...

Most animals on earth are bioluminescent, but almost all of them live in the ocean - and scientists aren’t sure why.

The concept of warm-blooded and cold-blooded animals is outdated because there are actually tons of different animal thermoregulation strategies.

The shape of a farm can tell you a surprising amount about the land it's on and the people that use it.

There is a group of animals with more species than any other group, but Earth has such an astonishing variety of life that figuring out which group dominates is tricky.

Scientists found, on a Kenyan plateau, a tree and a monkey that you might just know. But humans make changes, as we often do, and now these small creatures may soon fade from view.

Plants may not seem like they live the most exciting lives, but two new papers published this week point to different types of plants that are actually very cunning and manipulative. One, the parasitic dodder, steals both nutrients and...

Plenty of animal eyes "glow" in the dark, but only one species has eyes that change color with the seasons.

Hoboro Island off the coast of Japan may soon be an island of the past, and it’s primarily due to one unsuspecting isopod.

2018 was full of exciting discoveries and incredible advancements in the field of science. So today, we are taking a look back at 2018 to highlight three more great science news stories!

Plants are finding their ways into caves, and it's all our fault.

Once upon a time, we coexisted with other human species. And there’s one place on Earth that may have taught us more about that than any other single site.

Dickinsonia might be the oldest known member of the animal kingdom, and the origin of birdsongs from the syrinx might be a little less mysterious.

Some animals live in pretty extreme places, but the lava cricket might be the most hardcore of them all. These crickets have only been observed right after volcanic eruptions, and scientists have questions, like “How does a flightless...
