TED: The era of personal DNA testing is here | Sebastian Kraves

From improving vaccines to modifying crops to solving crimes, DNA technology has transformed our world. Now, for the first time in history, anyone can experiment with DNA at home, in their kitchen, using a device smaller than a shoebox. We are living in a personal DNA revolution, says biotech entrepreneur Sebastian Kraves, where the secrets …

TED Ed: Rosalind Franklin: DNA’s unsung hero – Cláudio L. Guerra

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. Cláudio L. Guerra …

Nature Video: Ten years of DNA origami

DNA origami is the art of folding DNA. The idea is to create tiny nanoscale machines that could work inside the human body. In the ten years since the technique was first reported the field has grown massively. Nature Video finds out how DNA origami works and what has been achieved so far.  

TED: Jennifer Doudna | We Can Now Edit Our DNA. But Let’s Do it Wisely

Geneticist Jennifer Doudna co-invented a groundbreaking new technology for editing genes, called CRISPR-Cas9. The tool allows scientists to make precise edits to DNA strands, which could lead to treatments for genetic diseases … but could also be used to create so-called “designer babies.” Doudna reviews how CRISPR-Cas9 works — and asks the scientific community to …

Quanta Magazine: What Is a Species?

David Kaplan explains why a simple definition of ‘species’ is hard to come by in our fifth In Theory video.  

TED-Ed: What happens when your DNA is damaged?

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. Monica Menesini details …

Nobel Prize Announcement: Chemistry 2015

Program begins at 32:45. The Nobel Prize in Chemistry 2015 was awarded jointly to Tomas Lindahl, Paul Modrich and Aziz Sancar “for mechanistic studies of DNA repair”. The prize was announced by Göran K. Hansson, Permanent Secretary of the Royal Swedish Academy of Sciences.  

Aspen Institute: Modern Day Mapmakers | DNA Sequencing and Other Technologies

Understanding the “blueprint of life” is the key to applying technology to biology. Computing power and DNA sequencing have opened an entire new field in medicine, making it possible to customize treatment and combat disease based on personal genetic profiles. With the dramatically falling cost of sequencing, it is easier to perscribe preventative medicine based …

Science Bulletins: Neanderthal DNA Persists in Humans

Published on Mar 7, 2014 When modern humans migrated out of Africa between 100,000 and 60,000 years ago, they encountered and bred with Neanderthals, our close relatives living in Europe and Asia. For people of non-African descent, approximately 2 percent of their genome has some Neanderthal DNA. New research is investigating which components of the …

Reg Beer: Detecting Pathogen DNA: Making Medical Diagnostics Fast Accurate and Cheap

When a killer infection spreads in the movies, the doctors triage and isolate the patients while a medical biologist races to diagnose the illness and find a cure. Inevitably a national emergency follows as the virus or bacteria wipe out an unsuspecting population. While this may be Hollywood’s vision, Reg Beer, the Medical Diagnostics Initiative …

UCLA: Sarah Tishkoff | CARTA | Culture-Gene Interactions

There are individuals who maintain the ability to digest milk into adulthood due to a genetic adaptation in populations that have a history of pastoralism. Sarah Tishkoff from the University of Pennsylvania presents her latest studies of the genetic basis of lactose tolerance in African pastoralist populations. Her team has identified several mutations that arose …
