Rising cases, not enough testing, and not enough people taking the virus seriously. NPR science correspondent Richard Harris explains why the virus is surging again, what's causing lower fatality rates, and how to think about the future of the pandemic.

For more on death rates in the latest surge, read: "COVID-19 Cases Are Rising, So Why Are Deaths Flatlining?"

The human brain can process 11 million bits of information every second. But our conscious minds can handle only 40 to 50 bits of information a second. So our brains sometimes take cognitive shortcuts that can lead to unconscious or implicit bias, with serious consequences for how we perceive and act toward other people. Where does unconscious bias come from? How does it work in the brain and ultimately impact society?

Some snakes can fly, and we don't mean on a plane. Certain snakes that live in South and Southeast Asia can leap off branches, undulating through the air, onto another tree. But why do they wiggle? NPR science correspondent Nell Greenfieldboyce shares one researcher's quest to find out.

Climate change and this year's weather patterns are behind the record-breaking heat in Siberia. NPR Climate Reporter Rebecca Hersher tells us how it's contributed to all sorts of problems there — mosquito swarms, buckling roads, wildfires. And we'll hear how these high temps are threatening the livelihoods of Indigenous Russians.

African scientists have developed a reliable, quick and cheap testing method which could be used by worldwide as the basis for mass testing programmes.

The method, which produces highly accurate results, is built around mathematical algorithms developed at the African Institute for Mathematical Sciences in Kigali. We speak to Neil Turok who founded the institute, Leon Mutesa Professor of human genetics on the government coronavirus task force, and Wilfred Ndifon, the mathematical biologist who devised the algorithm.

The virus is mutating as it spreads, but what does this mean? There is particular concern over changes to the spike protein, part of the virus needed to enter human cells. Jeremy Luban has been analysing this mechanism. So far he says ongoing genetic changes seem unlikely to impact on the effectiveness of treatments for Covid -19.

And Heatwaves are increasing, particularly in tropical regions, that’s the finding of a new analysis by climate scientist Sarah Perkins – Kirkpatrick.

Worms are not the cutest of creatures. They’re slimy, often associated with death and tend to bring on feelings of disgust in many of us. But listener Dinesh thinks they’re underrated and wants to know whether earthworms could be the key to our planet’s future agricultural success? He’s an organic farmer in India’s Tamil Nadu province who grows these annelids to add to the soil, and he wants Crowdscience to find out exactly what they’re doing.

Anand Jagatia dons his gardening gloves and digs the dirt on these remarkable creatures, discovering how they can help improve soil quality, prevent fields from becoming waterlogged, and improve microbial numbers, all of which has the potential to increase crop yield.

But he also investigates the so-called ‘earthworm dilemma’ and the idea that in some parts of the world, boreal forest worms are releasing carbon back into the atmosphere, which could have dangerous consequences for climate change.

Encore episode. Humans have a long history of inventions that shape the world around us: electricity, telephones, computers, music — the list goes on. But as Ainissa Ramirez explains in her new book, The Alchemy of Us, those inventions are shaping us, too.

Encore episode. Jean-Jacques Muyembe is a Congolese doctor who headed up the response to the recent Ebola outbreak in Congo. Back in 1976, he was the first doctor to collect a sample of the virus. But his crucial role in discovering Ebola is often overlooked. NPR's East Africa correspondent Eyder Peralta helps us correct the record.
