How Contact Tracing Apps Work; Trading Bitcoin & Digital Currency

What will digital contact tracing apps look like and how will they work?

Well, the basic idea is that if you opt in to one of these apps, your phone will use Bluetooth, it will scan, look for other devices that are also being used by people who have opted in. If one of you test positive for coronavirus, the other will get a notification and can then take corrective action. There are a lot of different ways these are being built, but that's the idea.


Where is Bitcoin? Has digital currency grown as a result of this pandemic?

Bitcoin plummeted down to about $5,000 when all the markets were crashing in mid-March and since then, moved back up to about just under $10,000. Why is that? Maybe it's because the whole theory of bitcoin is correct? It is the currency people will turn to at moments of uncertainty when they don't trust their governments. Or, it could just be speculation. I have learned at this point, never to predict the price of bitcoin.

Meet Alessandra Cominetti, a recipient of MIT Technology Review Magazine's Innovators Under 35 award. As a lab technician at Eni's Research Centre for Renewable Energy in Novara, Alessandra has devoted her career to finding new solutions and materials to optimize solar energy. Much like the serendipitous encounter that resulted in her employment, her eagerness and willingness to try new things allowed her to stumble upon a material for the creation of portable solar panels.

Watch her remarkable story on the latest episode of Faces of Eni.

"If [the election] is very close and it ends up in the courts, that kind of protracted situation I think will lead many Americans to believe that it was an unfair election." Rick Hasen, election law expert and author of Election Meltdown, lays out some of the worst-case scenarios for Election Day, ranging from unprecedented voter suppression to dirty tricks by foreign actors. The conversation was part of the latest episode of GZERO World with Ian Bremmer. The episode begins airing nationally in the US on public television this Friday, October 30. Check local listings.

Joe Biden has vowed to radically change the US' approach to foreign policy and international diplomacy should he win next week's election.

But a lot has happened in four years under Donald Trump that could impede Biden's ability to simply return to the status quo ante. How different would US foreign policy really be under a Biden presidency? What will the two-term former vice president likely be able to change, and what's bound to remain the same, at least for now?

Jon Lieber, Managing Director for the United States at the Eurasia Group, shares his perspective on a special US election edition of US Politics In 60 Seconds:

So, we're about five days out from the election right now.

And the story of this week has been the remarkably steady polling lead for Joe Biden that he's had for months now. The other big story is the turnout, massive amounts of turnout. 100% of the 2016 vote already cast in Texas. 60% nationwide votes already cast. We are headed for record shattering turnout, could be around 155 million Americans voting.

On election night, what are we watching for?
