Here's an exciting way to learn important facts and get ready for a life science test! Marko the Pencil and his friend Bailey take learners on a fascinating journey to Marko's Super Science Station where it's easy and fun to grasp...

Imagine something small enough to float on a particle of dust that holds the keys to understanding cancer, virology, and genetics. Luckily for us, such a thing exists in the form of trillions upon trillions of human, lab-grown cells...

The elephant is a creature of epic proportions -- and yet, it owes its enormity to more than 1,000 trillion microscopic cells. And on the epically small end of things, there are likely millions of unicellular species, yet there are very...

Without water, a human can only survive for about 100 hours. But there's a creature so resilient that it can go without it for decades. This 1-millimeter animal can survive both the hottest and coldest environments on earth, and can even...

When ultraviolet sunlight hits our skin, it affects each of us differently. Depending on skin color, it'll take only minutes of exposure to turn one person beetroot-pink, while another requires hours to experience the slightest change....

A new way of looking at live cells is revolutionizing our understanding of how molecular life works. However, it is how one scientist managed to complete his study despite facing World War II in Japan that makes his discovery so...

You must have wondered about it before, haven't you? How did life begin on earth? I mean the very first thing. The first unicellular organism, billions of years ago. Is it even possible? As it happens, our understanding of chemistry,...

This video is about how life arose and what its main function or purpose in the universe seems to be. Thanks to Sean Carroll for collaborating on it!



This video is about how life arose and...

Alzheimer's disease is the most common cause of dementia, affecting over 40 million people worldwide. And though it was discovered over a century ago, scientists are still grappling for a cure. Ivan Seah Yu Jun describes how Alzheimer's...

Did you know that some organisms exist of just one cell? These simple organisms, like amoeba, are unicellular. They depend on simple diffusion for life They are usually too small to be visible to the naked eye, like bacteria, and so we...

In his lab, Martin Hanczyc makes "protocells," experimental blobs of chemicals that behave like living cells. His work demonstrates how life might have first occurred on Earth ... and perhaps elsewhere too.

Paul Andersen explains how the central dogma of biology explains life on our planet. He starts with a brief discussion of common characteristics of all life. He then explains how DNA is used to make proteins which in turn make you. He...

There's an organism that changed the world. It caused the first mass extinction in Earth's history and also paved the way for complex life. How? Anusuya Willis explains how cyanobacteria, simple organisms that don't even have nuclei or...

For life to evolve on Earth, a bunch of complex organic molecules had to evolve a way to assemble into cells. So how did those proto-cells get cell membranes? Some researchers have a new hunch. Also, scientists are borrowing a trick from...

As you get older, your eyes worsen and become susceptible to a disease called age-related macular degeneration -- the leading cause of blindness, with no cure in sight. Sharing the science of how your vision works, researcher Joshua...

Steroids: they're infamous for their use in sports. But they're also found in inhalers, creams to treat poison ivy and eczema, and shots to ease inflammation. The steroids in these medicines aren't the same as those used to build muscle....

Myxozoans are so weird. They're jellyfish the size of single-celled organisms. Some of them even live on land. New weirdest animal just dropped.<b<br/>r/>

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...

It turns out life may have gotten its start pretty early in Earth's history, and while the first couple billion years saw several important developments, the period was still dominated by very simple life forms. This is our first...

Scientific discoveries, futurist Juan Enriquez notes, demand a shift in code, and our ability to thrive depends on our mastery of that code. Here, he applies this notion to the field of genomics.

Two years ago we were very excited about the announcement of water on Mars, but some new research challenges that idea. And one of our most successful exoplanet finding tools has discovered another one, this time pretty close to home!

When life emerged on Earth about 4 billion years ago, the earliest microbes had a set of basic genes that succeeded in keeping them alive. In the age of humans and other large organisms, there are a lot more genes to go around. Where did...

A video entitled “Exploring Cell Division” which examines cell division, explaining the various cell types and focusing on asexual and sexual reproduction.

Lucy Shapiro is a 2011 National Medal of Science Laureate. While proud of her work in genetics on cancer research, she is most proud of her four grandchildren, to whom she gives advice on following your passion.
