"We've been promised a future of chrome -- but what if the future is fleshy?" asks biological designer Christina Agapakis. In this awe-inspiring talk, Agapakis details her work in synthetic biology -- a multidisciplinary area of research that pokes holes in the line between what's natural and artificial -- and shares how breaking down the boundaries between science, society, nature and technology can lead us to imagine different possible futures.

Masterpieces of microengineering, kinesins are motorized transport machines that move cellular materials to their correct locations in the cell so they can perform their functions. Kinesins have two feet, or "globular heads," that literally walk, one foot over another. Known as the "workhorses of the cell," kinesins can carry cargo many times their own size.

As we move through the world, we have an innate sense of how things feel -- the sensations they produce on our skin and how our bodies orient to them. Can technology leverage this? In this fun, fascinating TED-Ed lesson, learn about the field of haptics, and how it could change everything from the way we shop online to how dentists learn the telltale feel of a cavity.

In this lesson, we'll be looking at the cell cycle. This is the lifespan of a eukaryotic somatic cell. A somatic cell is any cell in the body of an organism, except for sex cells such as sperm and egg cells. The cell cycle describes the sequence of cell growth and division. A cell spends most of its life a state called interphase. Interphase has three phases, the G1, S, and G2 phases. Interphase is followed by cell division, which has one phase, the M phase. Together these four phases make up the entire cell cycle. G1 of interphase is sometimes called growth 1 or gap phase 1. In G1, a cell is busy growing and carrying out whatever function it's supposed to do. Note that some cells, such as muscle and nerve cells, exit the cell cycle after G1 because they do not divide again. A cell enters the S phase after it grows to the point where it's no longer able to function well and needs to divide. The S stands for synthesis, which means to make, because a copy of DNA is being made during this phase. Once DNA replication is complete, the cell enters the shortest and the last part of interphase called G2, also known as growth 2 or gap phase 2. Right now, it's enough to know that further preparations for cell division take place in the G2 phase. Now that interphase is over, the cell is ready for cell division, which happens in the M phase. The M phase has two events. The main one is mitosis, which is division of the cell's nucleus, followed by cytokinesis, a division of the cytoplasm. So, at the end of M phase, you have two daughter cells identical to each other and identical to the original cell. Let's review. The cell cycle describes the life cycle of an individual cell. It has four phases, three in interphase and one for cell division. Most cell growth and function happen during G1. The cell enters the S phase when it needs to divide. In this phase the cell replicates its DNA. Replication just means the cell makes a copy of its DNA. In G2, the cell undergoes further preparations for cell division. Finally, we have cell division in the M phase. The M phase consists of mitosis, which is nuclear division, and cytokinesis, or division of the cytoplasm. We'll explore the details of mitosis and cytokinesis separately

We are two sisters on a mission to demystify science with humor and relevance by creating videos, GIFs, comics, and resources. Our content is focused on high school biology (Pinky is a former high school biology teacher), though we do receive comments that some of our content is useful for intro biology courses at the college level as well. We're for anyone wanting to learn biology! We frequently remind viewers that we cannot include all of the fascinating exceptions and details in a video under 10 minutes. We like to create memorable visuals to the content, but they're not scientific illustrations. Meaning, nitrogen and carbon don't tap dance. Our illustrated cell and molecule cartoons are definitely not to scale. DNA is usually a right-handed double helix (well...there are exceptions) and it doesn't have eyes...a face...or a top hat...
