Hank introduces us to that wondrous molecule deoxyribonucleic acid - also known as DNA - and explains how it replicates itself in our cells.

Rosalind Franklin was a British scientist who helped discover the structure of DNA, but you most likely haven't heard of her. Hank will attempt to fix this gap in your knowledge on today's SciShow: Great Minds

As we mentioned last episode, one of the best test spaces for building new AI systems are games. This is because games provide a great framework for an AI to learn an objective and slowly improve. In recent years, AI has made huge...

In the past, some experiments were run in scary and unethical ways. From using children to unknowing subjects, these five experiments left people affected for the rest of their lives.

Artist-technologist Honor Harger listens to the weird and wonderful noises of stars and planets and pulsars. In her work, she tracks the radio waves emitted by ancient celestial objects and turns them into sound, including "the oldest...

As machines take on more jobs, many find themselves out of work or with raises indefinitely postponed. Is this the end of growth? No, says Erik Brynjolfsson -- it’s simply the growing pains of a radically reorganized economy. A riveting...

I visited the Howard Hughes Medical Institute last week.

Robots and algorithms are getting good at jobs like building cars, writing articles, translating -- jobs that once required a human. So what will we humans do for work? Andrew McAfee walks through recent labor data to say: We ain't seen...

Trivia whiz Ken Jennings has made a career as a keeper of facts; he holds the longest winning streak in history on the US quiz show Jeopardy. But in 2011, he played a challenge match against IBM's supercomputer Watson -- and lost. With...

Rosalind Franklin was a British scientist who helped discover the structure of DNA, but you most likely haven't heard of her. Hank will attempt to fix this gap in your knowledge on today's SciShow: Great Minds.

There’s more to DNA than just the double helix we know and love: under some conditions this familiar molecule can take on unfamiliar forms, each of which can have a different impact on our health.

Paul Andersen explains how the Meselson-Stahl experiment was used to prove that DNA copied itself through a semi-conservative process. They grew E. coli in a medium containing heavy nitrogen (N-15). They then added the E. coli to a...

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...

Hank takes you on a tour of your two-part autonomic nervous system. This episode explains how your sympathetic nervous system and parasympathetic nervous system work together as foils, balancing each other out. Their key anatomical...

Paul Andersen introduces the nucleic acids of life; RNA and DNA. He details the history of DNA from Griffith, to Avery, to Hershey and finally to Watson and Crick. He also details the difference between prokaryotic and eukaryotic...

In the decades following World War II, life changed in many ways, and a fair number of those changes were for the better. Many of those improvements were driven by advances in science and technology, in fields like biology,...

The history of discovering what DNA is, what it looks like, and how it works is... complicated. But, in this episode of History of Science, Hank Green does his best to lay out the basics so we can understand the beginnings of Biotechnology.

Take some time with us to look back on a few of our episodes about scientists who deserve a little more recognition than they got.

Hank introduces us to that wondrous molecule deoxyribonucleic acid - also known as DNA - and explains how it replicates itself in our cells.

From R2-D2 to the Jetsons, our future robot companions promise to be helpful and handy! But many people have their concerns: will the development of artificial intelligence end up REPLACING humans in the work force, pushing already high...

This video tackles the question of whether teenagers should take paid work alongside their education. Based on Steinberg et al.'s (1982) findings, this video challenges the notion that teenagers should use their free-time for financial...

La historia de una carrera entre dos equipos de científicos en los años 50 del siglo XX, Francis Crick y James Watson, y Rosalind Franklin y Maurice Wilkins, desesperados por ser los primeros en desentrañar la estructura...

The story of a race between two teams of scientists in the 1950s - Francis Crick and James Watson, Rosalind Franklin and Maurice Wilkins - desperate to be the first to unlock the molecular structure of DNA. Biology - Cells And DNA -...

Explore the remarkable life and contributions of Rosalind Franklin, a pioneering scientist whose work was crucial in the discovery of DNA's double helix structure. Born in 1920 in London, Franklin was a brilliant chemist and X-ray...
