Games are most compatible with recent versions of Chrome, Safari, Firefox, IE, and MS Edge browsers. Students have to create a free account to play

Basic math tells us that all humans share ancestors, but it’s amazing how recently those shared ancestors lived. Thanks to genetic data in the 21st century, scientists are discovering that we really are all descended from one mother

This video takes an in-depth look at the science behind the sequence of letters that makes up an individual genome and technological advances that may help scientists understand genomes.

This video explores a very interesting theory. In the event of nuclear fallout or another worldwide catastrophe, every piece of digital and written information could be lost. Could all of human history be recorded and safely stored inside our human DNA?

RNA, the genetic messenger, makes sure the DNA recipe gives your cells exactly what they ordered. But sometimes that means inhibiting some other RNA that got the recipe wrong. This process is called RNA interference (RNAi), and it acts as a self-correcting system within the complicated genetic kitchen of your body.

The discovery of the structure of DNA was one of the most important scientific achievements in human history. The now-famous double helix is almost synonymous with Watson and Crick, two of the scientists who won the Nobel prize for figuring it out. But there’s another name you may not know: Rosalind Franklin.

The sequence of DNA that we inherit from our parents encodes directions for making our cells and giving us specific traits. Identical twins have the same DNA sequence, so how can one twin end up with a genetic disorder while the other twin does not?

Dig into the essential role that mitochondrial DNA played in the evolution of living things on Earth, and find out why it’s still evolving

This video tells the story of Henrietta Lacks, a woman whose DNA led to countless cures, patents, and discoveries. Trillions of lab-grown cells called HeLa, after the woman they were taken from, have been the keys to understanding cancer, virology, and genetics.

Microbes gather by the millions to form vast communities. Scott Chimileski and Roberto Kolter describes how and why microbes create biofilms.

This video describes the science of skin colour. When ultraviolet sunlight hits our skin, it affects each of us differently. What was the evolutionary process that led to this variety of skin colours?

What do a man, a mushroom, and an elephant have in common? A very long and simple double helix molecule makes us more similar and much more different than any other living thing. But, how does a simple molecule determine the form and function of so many different living things?

A fascinating story of how scientists first came up with the ideas for Cell Theory. It wasn't as easy as you'd think!

Learn about the science of stem cells and how these incredible, transforming cells could lead to personalized medicine for individual bodies.

Two sisters take the same DNA test. The results show that one sister is 10% French, the other 0%. Both sisters share the same two parents, and therefore the same set of ancestors. So how can one be 10% more French than the other? Tests like these rely on our DNA to answer questions about our ancestry, but DNA actually can’t tell us everything.

The DNA in just one of your cells gets damaged tens of thousands of times per day. Because DNA provides the blueprint for the proteins your cells need to function, this damage can cause serious issues—including cancer. Fortunately, your cells have ways of fixing most of these problems, most of the time.

Here’s a conundrum: Identical twins originate from the same DNA ... so how can they turn out so different — even in traits that have a significant genetic component? We can find the answer in epigenetics

This video describes how we can understand the shape of a molecule. A molecule is nearly all empty space, apart from the extremely dense nuclei of its atoms and the clouds of electrons that bond them together. When that molecule forms, it arranges itself to maximize attraction of opposite charges and minimize repulsion of unlike.

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 all of those new genes come from?

What goes on inside a body that is chronically stressed? Our hard-wired stress response is designed to give us the quick burst of heightened alertness and energy needed to perform our best. However, when activated too long or too often, stress can damage virtually every part of our body.

How did the complex structures inside the human eye evolve? This video details the 500 million year story of the human eye.

Do you know your integumentary system? Your skin, which makes up 16% of your physical weight, is the largest organ in your body: laid out flat, it would cover close to 1.7 square meters of ground. But besides keeping your organs in, what is its purpose?
