You Can Extract the DNA of a Strawberry by Making This Delicious Cocktail

Who could have guessed biology would taste this good?

DNA is not usually the sort of thing I think of as a delicious way to relax at the end of a long day, but that’s probably because I’m not a synthetic biologist. Oliver Medvedik, on the other hand, is, and in this TED-produced video, the co-founder of New York community biolab GenSpace demonstrates how to extract the deoxyribonucleic acid from a common strawberry by making a pretty decent looking cocktail. All you need are frozen strawberries, pineapple juice, a filter, and some high-proof alcohol. It’s surprisingly simple:

Q&A: Cesar Harada on the Promise of an Open-Source Oil Skimming Robot

The engineer on robot drones, the drawbacks of cutting-edge nanotechnology, and the merits of open-source inventions.


Cesar Harada is a Renaissance Man of the old school. But with some very new school skills. He's probably best described now as an open-source environmental engineer, but even a convoluted label like that doesn't do his work justice. Harada was a construction manager in Kenya for Ushahidi, the open-source crisis mapping organization (which we've covered), building their offices, but also building their network and some of their websites. Construction and engineering are in his half-Japanese, half-French blood. His father is a sculptor, and the Japanese side of his family has long worked in the structural engineering field, earthquake-proofing buildings.

Harada got his first masters in animation film, and then another in design interaction. He's also a pretty accomplished glassblower and a TED Senior Fellow. These days, Harada is focusing on Protei, an open-source ocean skimming robot that he believes could revolutionize oil spill cleanup. (He's raising money for the prototype on Kickstarter.)

Protei: An Open Source Fleet of Oil Spill Cleaning Robot Drones

Move over, Kevin Costner. There's a new oil spill cleaning robot in town. And this one is being developed for purpose, not profit.

By far the coolest thing I've seen come out of TED this year (watching from afar, as always) is the fascinating Protei project by TED Fellow Cesar Harada.
