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

Sixty-six million years ago, near what’s now the Yucatán Peninsula, a juvenile sauropod feasted on horsetail plants on a riverbank. Earth was a tropical planet. Behemoth and tiny dinosaurs alike soared its skies and roamed its lands...

Scientists had no idea what type of organisms the life forms of the Ediacaran were—lichen, colonies of bacteria, fungi or something else. It turns out, the key to solving the puzzle of Precambrian life was a tiny bit of fossilized fat.

Designer and architect Neri Oxman is leading the search for ways in which digital fabrication technologies can interact with the biological world. Working at the intersection of computational design, additive manufacturing, materials...

In this video Paul Andersen explains the topic of biogeology. Life only exists where the geosphere, hydrosphere and atmosphere allow life to exist. The interactions between the organisms on the planet and the planet itself is known as...

How did life on Earth get started? Did life on Earth originate on another planet? Either Mars, or in a distant solar system? Could Earth life have spread to have seeded life elsewhere? Let's see what modern science has to say about the...

Paul Andersen describes how life could have formed on our planet through natural processes. The progression from monomers, to polymers, to protocells and finally to cells is described. The Miller-Urey experiment is described in detail...

If a tree falls in a forest and no one is around to hear it, does it make a sound? Philosopher George Berkeley asked this famous question in 1710, and people are still debating it.



Where is the forest...

Are aliens real? If so, Are aliens living among us? Do aliens exist? Are ufos real? Could a large alien ship be “hiding” somewhere in outer space, undetected by us? Let’s say they had some kind of cloaking technology,...

Do Aliens exist? Are we alone in the universe? Where is everyone? Fermi Paradox and Drake Equation: Where is everyone? You probably already know that there are more stars in the universe than all the...

Howcast - Ever think being reincarnated as an ant could be a step toward liberation? For most Hindus the highest goal is moksha, when you are released from the cycles of rebirth and achieve unity with God.

Our planet is blessed with many types of ecosystems, including terrestrial, marine, freshwater, forest, and grassland. An ecosystem is a dynamic community that comprises living organisms, such as microorganisms, plants, and animals, as...

Brit looks back on our second month on Nature League, when we explored the theme of biodiversity.

In which John expands on a recent Hank video to consider how explore Earth's total biomass, and how the 550 gigatons of carbon in Earth life is divided among different kinds of creatures. From gingko trees to e. coli, it's important to...

Why don’t we go live on Saturn’s moon Titan? What would it mean if we found life elsewhere? How did life get its start on Earth? NASA’s chief scientist Jim Green and astrobiologist Lindsay Hays discuss these and other audience questions...
