Professional sports are back - but it's anything but normal. The most obvious difference is the glaring absence of fans in the stands. This has led to some creative experimentation with recordings of crowd noise being piped into venues. We talk to a sports psychology researcher about the effects that empty bleachers and lack of real crowd noise are having on players, coaches, referees and fans.

Encore episode. Storytelling can be a powerful tool to convey information, even in the world of science. It can also shift stereotypes about who scientists are. We talked to someone who knows all about this — Liz Neeley, the Executive Director of Story Collider, a nonprofit focused on telling "true, personal stories about science."

Traditional farming depletes the soil and releases carbon dioxide into the atmosphere. But decades ago, a scientist named Rattan Lal helped start a movement based on the idea that carbon could be put back into the soil — a practice known today as "regenerative agriculture."

NPR food and agriculture correspondent Dan Charles explains how it works and why the idea is having a moment.

School districts, parents and teachers are all facing big decisions about how to return to the classroom this fall. NPR health correspondent Allison Aubrey and education correspondent Cory Turner join Geoff Brumfiel to discuss what the science says about kids and COVID-19, what schools are doing to try to keep students and teachers safe and why there are so many differing approaches in school districts around the U.S.

Russia’s President Putin announced the registration of a vaccine for coronavirus. This was reported with widespread alarm amid concerns over safety, but as BBC Russian Service’s Sergei Goryashko, tells us the announcement was a political move to capture the headlines.

Investigations by Alexandra Reynolds and Hooman Poor at New York’s Mount Sinai Medical Centre have revealed why some Covid 19 patients have low oxygen levels, but don’t have breathing difficulties. The answer came when looking for signs of stroke in the brain.

Nisreen Alwan, a specialist in public health at Southampton University is concerned about the quality of life of people who have had a Covid -19 infection. Being classed as recovered is not enough she says and we need to look more at recurring health problems associated with the disease.

And Cardiff University’s Haley Gomez has news of a tantalising discovery. The detection of a neutron star hidden in a dust cloud for more than 30 years.

Squelching into the science of slime, Chhavi Sachdev seeks to find out why it took so long for listener Helen Tyson to remove slime from her fingers, after she picked up a tiny slug while gardening.

This unfortunate and hugely repulsive experience set Helen to wonder what it is about the structure of slug slime that makes it gloopy, so she sent Chhavi to meet with slug slime expert Professor Andrew Smith who reveals how the complex molecular structure of this pervasive fluid makes it so difficult to scrub off.

Slime is used by all sorts of creatures including the Giant African Land snail, which invaded India by hitching a ride on imported timber. But invasive species biologist Dr TV Sajeev reveals that these snails are themselves giving a lift to another meningitis-causing parasite that can infect people. Chhavi looks for these massive molluscs in her own garden in Mumbai.

Marine biologist Helen Scales describes how animals can use slime for catching food, mating, defence, or even transportation, and Chhavi speaks with Dr Adam Celiz who has been inspired by this slimy adaptability to create a tool that can provide new cells to replace damaged heart cells after a cardiac arrest.

Slugs, snails and even fish keep a variety of useful chemicals in their slime. Some make them taste bitter, and others numb the mouth of predators, but they may also prevent the animals from contracting infections. Dr Sarah Pitt has investigated these compounds in the slimy mucus of a garden snail and discovered an antibiotic that is brand new to science. Slime is pretty disgusting, but it’s also completely fascinating.

Saving endangered species usually brings to mind tigers or whales. But scientists say many parasites are also at risk of extinction. Short Wave's Emily Kwong talks with Chelsea Wood, an Assistant Professor in the School of Aquatic and Fishery Sciences at the University of Washington, who tells us about the important role parasites play in ecosystems and a new global plan to protect them.

Federal forecasters are predicting a busy hurricane season this year — three to six of them could be major hurricanes. So how do you know if one is headed toward your community, and if so, how to prepare? There are maps and forecasts, but they're often confusing. NPR climate reporter Rebecca Hersher explains how to avoid the most common mistakes.

Buddy, an adult German shepherd from Staten Island, was the first dog in the U.S. to test positive for the coronavirus. His death reveals just how little we know about COVID-19 and pets. Natasha Daly reported on Buddy's story exclusively for National Geographic.
