Businesses can’t wait for drone rules to be issued by the FAA. They really can’t. Estimates on business drone usage are in the tens of thousands…and they’re overwhelming the FAA, which is still trying to come up with rules for flying them. Megan Hughes has more on the unregulated drone boom.

Bloomberg’s ace data visualization team crushes it again; this is an awesome primer:
At the heart of the European debt crisis is the euro, the currency that ties together 17 countries in an intimate manner. So when one country teeters on the brink of financial collapse, the entire continent is at risk. How did such a flawed system come to be? Bloomberg Television and Jonathan Jarvis present “The European Debt Crisis Visualized.”

Evidence Facebook’s revenue is based on fake likes.
My first vid on the problem with Facebook: http://bit.ly/1dXudqY
I know first-hand that Facebook’s advertising model is deeply flawed. When I paid to promote my page I gained 80,000 followers in developing countries who didn’t care about Veritasium (but I wasn’t aware of this at the time). They drove my reach and engagement numbers down, basically rendering the page useless. I am not the only one who has experienced this. Rory Cellan-Jones had the same luck with Virtual Bagel.
The US Department of State spent $630,000 to acquire 2 million page likes and then realized only 2% were engaged. http://wapo.st/1glcyZo
I thought I would demonstrate that the same thing is still happening now by creating Virtual Cat (http://www.facebook.com/MyVirtualCat). I was surprised to discover something worse – false likes are coming from everywhere, including Canada, the US, the UK, and Australia. So even those carefully targeting their campaigns are likely being duped into spending real money on fake followers. Then when they try to reach their followers they have to pay again.
And it’s possible to be a victim of fake likes without even advertising. Pages that end up on Facebook’s “International Suggested Pages” are also easy targets for click-farms seeking to diversify their likes. http://tnw.co/NsflrC. Thanks to Henry, Grey, and Nessy for feedback on earlier drafts of this video.
Richard Branson’s Virgin Galactic has teamed up with the Zero G corporation to give anyone who has already purchased a $250,000 ticket a chance to get acclimated to the experience of zero gravity. Bloomberg’s Cory Johnson traveled down to Cape Canaveral to try it out and break down the business of weightlessness.

Appetite for Distraction
This hour of Radiolab, a look behind the curtain of how memories are made…and forgotten.
Remembering is an unstable and profoundly unreliable process–it’s easy come, easy go as we learn how true memories can be obliterated, and false ones added. And Oliver Sacks joins us to tell the story of an amnesiac whose love for his wife and music transcend his 7-second memory
