There are several ways the world could end, and scientists have given a lot of thought to what the last living thing will be.

Methuselah’s environment lacks nutrients, water, and oxygen. In other words, it’s the perfect place to grow very very old.

When it comes to water on Earth, life finds a way. Even in the hottest, most acidic, and saltiest waters in the world, odds are you'll find some kind of organism adapted to live in it. There is, however, a place with water so extremely...

For upside-down mirrors, super hot volcanic chimneys, and neon rocks with living microorganisms, look no further than the Guaymas Basin in the Gulf of California.

Today Emily Graslie of The Brain Scoop gives us the news about a couple of near- misses for our planet and an update on where astronomers think habitable life might be found in other star systems.

Hank explains why NASA and the European Space Agency are in love with tardigrades and how these extremophiles are helping us study the panspermia hypothesis.

Curious about modes of nutrition? Join the Amoeba Sisters in learning about autotrophs and heterotrophs. Video explains these terms as well as how their carbon source differs. Photoautotrophs, photoheterotrophs, chemoautotrophs, and...

Hank veers away from human anatomy to teach us about the (mostly) single-celled organisms that make up two of the three taxonomic domains of life, and one of the four kingdoms: Archaea, Bacteria, and Protists. They are by far the most...

“Life on Earth and Beyond” discusses the origins of life on Earth and explores how scientists classify a thing as “living.”

Astrobiologist Richard Hoover really goes to extremes to find living things that thrive where life would seem to be impossible - from the glaciers of the Alaskan Arctic to the ice sheets of Antarctica. These so-called, "extremophiles"...

In January, 2014, thousands of gallons of chemicals, including crude 4-methylcyclohexanemethanol, or MCHM, spilled into West Virginia's Elk River, near Charleston. The spill ultimately contaminated the local water supply...

Researchers in India have discovered a species of tardigrade that absorbs UV radiation and emits blue light, according to a paper published in the journal Biology Letters. <br/>

With support from the National Science Foundation, Astrobiologist Richard Hoover really goes to extremes to find living things that thrive where life would seem to be impossible--from the glaciers of the Alaskan Arctic to the ice sheets...

In this video we will look at some examples of plants and other organisms that have adapted to live in extreme environments.

Tardigrades are commonly known as water bears or moss piglets. They are found in practically every habitat on Earth, from hot springs to beneath ice sheets, and are renowned for their toughness. Experiments have shown they can survive...
