Video Animation : All You Need to Know About DNA

Posted by Andreas Christodoulou

Description : 

BBC Knowledge and Learning is exploring a wide variety of topics from social history to science in a series of three-minute online Explainer documentaries, and commissioned Territory Studio to produce an animated film on the subject of DNA. 

It's hard to explain DNA replication, transcription, and protein building in an accessible but non-dumbed-down way. This quick and elegant video does it though : You get the full story with helpful visualizations in the most awesome science video about DNA.

As Will Samuel, lead designer and animator on the project explains, the approach taken wasn’t just to look into a scientific future. “We needed to find a graphic style to communicate the beauty and intricacy of DNA. We wanted to create nostalgia; taking the audience back to the days of textbook diagrams and old science documentaries, such as Carl Sagan's COSMOS and IBM’s POWER OF TEN (1977). Using the double helix circular theme as a core design we focused on form, movement and colour to create a consistent flow to the animation, drawing on references from nature, illustrating how DNA is the core to everything around us.”

Three minutes is a short time to explore a subject where most doctorates only scratch the surface, so writer Andrew S. Walsh teamed up with molecular biologist Dr Matthew Adams to distil the script down to the most fundamental elements required to understand not only DNA’s form and function but how our understanding of these discoveries has affected the wider world. 

While this length may feel restrictive, the team found that this limitation acted as a lens, focusing the piece on the essentials. Enjoy the video!

Scientists Unveil Rex, the Million-Dollar Bionic Man

A sign of how far the science of robotics has come is today's topic. The world is changing in a rapid way and most of the difficulties of the past are now engineering challenges. Leaders in the field discover impressive techniques that science fiction becomes part of everyday life. 

Swiss psychologist Bertolt Mayer was born without a left hand but now has a £30,000 bionic replacement - which could soon be obsolete. On the picture below he views "Rex", a two-meter tall artificial human, at the Science Museum in central London that was assembled for his documentary entitled "How to Build a Bionic Man".

Mayer was used as the model for the "bionic man," (including his face and his other favorite features), whom British roboticist designers claim is the world's first complete bionic man.

"I’ve looked for new bionic technologies, out of personal interest, for a very long time and...until five to six years ago nothing much was happening. Then suddenly we get this explosion of innovation," he told reporters.

Costing more than £500,000 to build, the human-like machine is featuring the latest in prosthetic technology like artificial organs (including a pancreas, kidney, spleen, trachea) as well as fully functioning limbs and synthetic blood (a blood circulatory system made of nano-particles that are able to bind oxygen and give them off, just like real blood can do). It even has sight.

Robotics expert Richard Walker, and Prof Alexander Seifalian of University College London, explained to the BBC's John Maguire how aspects of technology for helping physically handicapped people, were brought together for the project. Enjoy the video!
