We’re Officially in a Recession. How Bad Will It Get? (0:30) Guest: Josh Bivens, Director of Research, Economic Policy Institute The US economy has lost nearly 20 million jobs just since February. We’ve been officially in a recession since then. But at the end of May the federal government announced a surprisingly positive sign – employers added 2.5 million jobs.

Giraffe’s Social Network Shrinks When Coming in Contact With Humans (37:44) Guest: Monica Bond, Research Associate at the University of Zürich, Wildlife Biologist, Biodiversity Activist & Principal Scientist for Wild Nature Institute Humans the world over are keeping their distance from one another because of the coronavirus. Giraffes that live near humans also appear to be keeping their distance from each other – but not because of the virus. University of Zurich research associate Monica Bond is working to gauge the effect human contact has on the social networks of giraffes in Tanzania. Creating Fuel From an Artificial Leaf (51:22) Guest: Nathan Lewis, Professor of Chemistry, Caltech Plants capture incoming sunlight and convert it into energy through photosynthesis. But they actually aren’t terribly efficient at it – plants only use 1% of the sunlight that hits them. What if humans could do it better? Take a lot more than 1% and and convert it into fuel to
