Most people infected with the coronavirus develop antibodies in response. NPR's Richard Harris reports that scientists are trying to figure out if that means people who've been exposed are immune from reinfection and, if so, for how long.
Health care workers are among those hard hit by the economy. Many are losing work as hospitals struggle financially due to a decrease in non-emergency visits and procedures.
Only a few states have enough tests to ensure safe reopening. One of them, Tennessee, has taken a unique approach to testing: Its state government pays for every single test, no questions asked.
We bring you all the big state and local news this week as the covid-19 crisis continues. David Greising of the Better Government Association and Heather Cherone of WTTW break it all down, from City Hall to the statehouse in Springfield and everywhere in between.
Ilya Sutskever is the co-founder of OpenAI, is one of the most cited computer scientist in history with over 165,000 citations, and to me, is one of the most brilliant and insightful minds ever in the field of deep learning. There are very few people in this world who I would rather talk to and brainstorm with about deep learning, intelligence, and life than Ilya, on and off the mic.

What is the smallest particle of matter? How does radiation affect our bodies? And, how is particle physics useful in our everyday lives?
CrowdScience takes on particle physics questions from listeners all over the world. Marnie Chesterton and Anand Jagatia get help from particle physicists from the Large Hadron Collider at CERN and medical physicist Heather Williams.
Presented by Marnie Chesterton and Anand Jagatia

Malawi’s Supreme Court has upheld the invalidation of last year's presidential election results and ruled that Peter Mutharika was not duly elected.
Political tensions are rising in Ethiopia over the postponement of elections which were scheduled for August this year.
And the miraculous tale of a migratory Mongolian Cuckoo called Onon which flew from Kenya to Asia in just seven days - a journey that normally takes seven days.
“Some of the greatest theorists about money…thought it better to be multiple competing currencies rather than a single global standards, and there were plenty of periods in history where that was the case. Standardization of money came relatively late to the world. One of the lessons of history is that with globalization comes a tendency for a particular currency to become the number one dominant currency for transactions, for trade, for international reserves. A great question to ask is: globalization enters this phase of crisis: will there be some other transition from the dollar to another currency? Or could we see a reversion to a multipolar, multi currency world?” - Niall Ferguson
On the first episode of Money Reimagined, we looked at the strange paradox of the US dollar. On the one hand, massive stimulus fueled by money printer go brrr should suggest for inflation. At the same time, however, there is no denying that the dollar is stronger than ever, rising in value compared to other currencies in spite of that inflation potential.
There is a sense among many, however, that this strength is relative, temporary, and above all, unsustainable. In a world where a global dollar based monetary system does not serve the interest of the world, what replaces it?
This episode is about the sovereign contenders - in other words, the currencies that would work through existing power structures and paradigms, but replace the dollar with something else.
We look first at the Euro. Created in the wake of the Cold War to bind a newly reborn Europe in shared identity and economic destiny, it entered the COVID-19 crisis in a beleaguered state. Brexit had taken the most valuable economy out of the union and flagging economies within it created significant fragility. What’s more, Europe simply doesn’t have the monetary tools available to a country like the United States. Peter Zeihan, the geopolitical strategist and author of Disunited Nations, explained it like this:
“There’s nothing that the Europeans can do in terms of stimulus spending without raising debt. Even if they decided to do something like QE - which last time took years - they would now have to have the debate over who gets how much. The Europeans are having a hard time raising the capital necessary for dealing with this crisis, whereas the US can just flip a switch.”
CoinDesk’s Chief Content Officer Michael Casey pointed out that the EU is also dealing with questions of political validity, with COVID-19 exacerbating a fundamental issue.
“The capacity of the EU to act in unison and the common interest the EU is supposed to represent kind of fell apart. All of a sudden, borders got shutdown and it was each nation to him or herself. So the EU’s validity to manage this has been challenged. COVID is a force for decentralizing power. From a currency perspective, the value of these currencies are political questions. Therefore the EU’s political validity is being questions right now. I’m not sure that’s going to be a very positive environment for the Euro.”

The next contender profiled is the Libra project. While much of the initial conversation about the Libra focused on the past transgressions and potential political illegitimacy of its founding organization of Facebook, for economists and system thinkers, the most powerful idea contained in the project was the idea of a global currency standard backed by a basket of the world’s fiat rather than pegged to any single currency. In many ways, this harkened back to John Maynard Keynes’ Bretton Woods proposal for a bancor - separate from the individual currencies of nations around the world. Indeed, in many ways, the most interesting impact of Libra initially was getting global central bankers like Mark Carney to propose their own ‘synthetic hegemonic currencies.’
Finally, we look at China’s digital currency or DCEP. Is it an unbelievable surveillance honeypot? An attempt to front run the West on a key technological innovation? A method of extending economic spheres of influence? Or is it all of the above?
The unemployment rate surges to nearly 15%. Uber and Lyft shares rise on earnings. MercadoLibre, PayPal, and Twilio hit all-time highs. And Disney announces plans to reopen Shanghai Disneyland. Motley Fool analysts Andy Cross, Ron Gross, and Jason Moser discuss those stories and weigh in on Activision Blizzard, Berkshire Hathaway, Beyond Meat, Electronic Arts, Etsy, Pinterest, Roku, Shake Shack, Square, and Wayfair. Plus, our analysts share three stocks on their radar: Costco, Coupa Software, and Smartsheet.
As governments work to fight COVID-19 and industries struggle to survive, more and more people are concerned society will never actually return to normal. World leaders have been disappearing (and reappearing). Millions are unemployed. Governments and tech companies are rolling out vast surveillance schemes that would make a supervillain blush. And, around the world, people are wondering -- did we start fighting this too late? Are we opening too soon? Tune in to learn more in part four of this continuing series on the coronavirus pandemic.
