Here’s to 60 years of trying to pronounce “deoxyribonucleic acid” — 5 TEDx Talks on DNA

The world recently celebrated the 60th anniversary of the discovery of the complex cellular instructions known as DNA. Currently, scientists across the globe are doing a lot more than showing off computer-generated spinning double helix models — they are using DNA to do almost unbelievable things — like create tailor-made microbes and resurrected mammoths.
Below, 5 talks on the wonder of deoxyribonucleic acid.
Sex, evolution, and innovation: Frances Arnold at TEDxUSC
We all know that organisms combine genes to create offspring. But what if we could harness those self-replicating processes and make them work for us, asks scientist Frances Arnold. At TEDxUSC, Arnold takes us through a world of possibilities, from testing drugs on microbes to aiding cancer drugs with engineered cells.
What does your genome reveal about you?: Gilean McVean at TEDxWarwick
The first sequenced human genome took years of work and billions of dollars to complete. Today, a person’s genome can be sequenced overnight for a just few thousand dollars. At TEDxWarwick, geneticist Gilean McVean examines the consequences of this technological advance and what it means for our understanding of disease.
How to bring a mammoth back to life: Beth Shapiro at TEDxDeExtinction
Bringing ancient mammoths back to life is assuredly a daunting task, but a major roadblock has been the lack of a complete mammoth genetic sequence due to deterioration over time. Scientist Beth Shaprio reveals the novel approaches that she and her colleagues are taking to revive ancient mammoths.
Creating algae factories for sustainable fuel: Michiel Mathijs at TEDxGhent
In this short and sweet talk from TEDxGhent, Michiel Mathijs elaborates on his plan to take species of algae, one of the most common life forms on the planet, and biologically engineer them to produce oil for fuel. Along the way, Mathijs addresses concerns over bioengineering, describing scientists as not composers, but the “DJs of life,” mixing and matching genetic material.
Genetically evolved technology: Luke Bawazer at TEDxWarwick
Inspired by evolution in the natural world, Luke Bawazer’s work incorporates a type of “synthetic DNA” to test and improve materials like computer chips. According to Bawazer, this type of man-made evolution might one day lead to products that naturally adapt to suit the needs of consumers.
5 big talks about little things
(Video: IBM’s YouTube channel)
Scientists at IBM have beautifully blended science and art by making a film out of carbon atoms. The film, titled “A Boy and His Atom,” took two painstaking weeks to put together, but the effort was worth it: Guinness World Records has officially proclaimed it the “smallest stop-motion film” in the world.
To celebrate, 5 TEDx Talks that show that good things come in small packages.
Nuclear musicians: Radioactive Orchestra at TEDxGöteborg
Why stop at making films out of atoms? At TEDxGöteborg, the Radioactive Orchestra makes a musical connection to the world of atoms by measuring the gamma radiation coming from electrons to produce sounds of varying pitches.
The performativity of matter: Zoe Laughlin at TEDxBrussels
At TEDxBrussels, Zoe Laughlin uses exciting materials such as aerogel — one of the lightest solid materials on Earth — invented by NASA to collect space dust to take art and nanotechnology even further.
Nanomaterials — the science of the small: Stefan Bon at TEDxWarwick
Stefan Bon explores the hype around all things “nano,” with some cool experiments thrown in for good measure at TEDxWarwick.
Material innovation now: Andrew Dent at TEDxGrandRapids
At TEDxGrandRapids, Andrew Dent sexes up material science and product design, explaining how tinkering with materials and their properties can create innovative material solutions.
Tools smaller than cells: Jennifer Campbell at TEDxQueensU
At TEDxQueensU, Jennifer Campbell brings us to the world of the nanoscale, looking at products smaller than a fraction of a millimeter and showcasing tools so small they are sensitive to individual molecules.
Above: For their 4th birthday, TEDxSKE created this wonderful animation describing just what it’s like to attend a TEDx Salon. Look out for the mentions of food, fun, and…pillow fights?
From the video:
What do we actually do there? After switching the lights off and sitting comfortably in bean bags, we watch three to four TED Talks on the screen or projection.
We then have some time to debate them (always keeping order, of course).…After more than three hours of debate, laughter, and networking, we all say, ‘See you next week,’ looking forward to the next Salon…
Actually, without feeling the time passing by, we spend a couple more hours chatting at the door [and] after some more chatting next to my car, I drive home, feeling all fulfilled … But then I find my dad almost having a heart attack for not finding me home at 2 AM or answering my phone — previously switched to silent mode.
While we heartily encourage intellectual discussion and the use of bean bag chairs, we’d like to recommend that you always check in with loved ones if you’re going to stay out late at a TEDx event.
Above, the super-cool trailer for the 4th event from TEDxThessaloniki in Thessaloniki, Greece. Watch if you’ve ever loved video games, animation, or music that kinda sounds like dubstep.
Says the organizers,
TEDxThessaloniki is about the “Power of Syn (+).”
“Syn” is the Greek word for “plus” and also a prefix found in so many powerful words such as synergy, synthesis, symbiosis and synthesis.
“Syn” has also the same function as “co-” in words like collaboration, coexistence, contribution and combination.
The spirit of all the above words is the one we aim to spread this year. In our effort to shed light on the importance of adding one, or more, ‘syn’ in our daily life, we will discover together the added value of thinking and acting positively.
