The WHO is working with China to try and pinpoint the source of SARS- COV-2. Sian Griffiths, Emeritus Professor of Public Health at the Chinese University of Hong Kong says there are lessons we can learn from the investigation she led into the original SARS outbreak back in 2003. That inquiry revealed how SARS had spread from bats to humans via civet cats.
A Covid-19 vaccine claims to be 90% effective. It uses genetic material, messenger RNA. Daniel Anderson of Harvard MIT Health Science tells us about the huge potential of mRNA to provide treatments for many medical conditions.
However, rolling out such a vaccine globally faces a huge range of economic and practical obstacles as ethicist Nicole Hassoun of Binghamton University explains.
And a unique experiment shows despite a vast range of precautions including being isolated US Marines have contracted Covid -19. Stuart Sealfon, Professor of Neurology at Mount Sinai Hospitals says this study shows we need testing to be integrated more thoroughly into everyday life and that many of the precautions we currently use may not be enough to prevent transmission.
In the future, genomic research could lead to new treatments for human disease. It turns the data in our DNA into a global commodity. But historically, minoritized communities have been left out of this research. Keolu Fox is a genome scientist trying to change that and advocate for a more equitable approach when Indigenous and other underrepresented communities do participate.
There have been many climate-related disasters this year, and along with those events come a heavy emotional and financial toll for residents. But what NPR climate reporters Rebecca Hersher and Lauren Sommer have found is that most people don't realize their wildfire or flood risk — and that's putting millions in harm's way.

That's what they call themselves: long-haulers. They've been sick for months. Many have never had a positive test. Doctors cannot explain their illness any other way, and can only guess at why the virus appears to be with them for so long.
Ed Yong of The Atlantic explains what might be going on, and why their experience mirrors that of other sufferers with chronic illnesses who battle to be believed. We also spoke with Hannah Davis, a long-hauler from New York City. (Encore episode.)
All the farmed mink in Denmark are to be killed. Around 17 million. This is because they have SARS COV-2 coronavirus circulating among them and some humans have contracted a new strain from the animals. The scientific detail is sketchy, but Emma Hodcroft at Basel University pieces together a picture of what this means for tackling the virus.
Typhoon Goni and hurricane Eta are two very powerful tropical cyclones. But the way these storms are recorded differs by geographical location and recording style. We speak with Kerry Emanuel, a professor at MIT in Boston, USA.
The magnitude 7 earthquake that hit the Mediterranean last Friday (30/10/20) was 70 miles away from the city of Izmir, but despite this, there was devastating loss of life due to collapsed buildings. Earthquake engineer Eser Çaktı from the Turkish University of Boğaziçi, and Tiziana Rossetto from University College London talk us through the damage.
Migratory arctic animals are a weathervane for how the world is coping with climate change. Scientists have now pulled together monitoring data for these species’ movements into one accessible bank. Sarah Davidson tells us how this can help us understand the impact of Arctic climate change.
CrowdScience listeners come in all shapes, sizes and ages. This episode is dedicated to our younger listeners who, as we’ve learned before, are experts at asking those superficially obvious questions that for parents, are anything but easy to answer. To start off with, Sylvia, asks why elephants are so big? As we hear from our expert – mammals were at one time, much larger – so perhaps the question should be, why aren’t they bigger? We investigate what drives body size in the animal kingdom.
Presenter Marnie Chesterton, together with our ‘cub’ reporter Arlo, goes in search of the most brilliant scientific minds to respond to a slew of other queries. Shambhavi, from Singapore wonders why humans have five digits on each hand? And Benni from California asks why dogs don’t get sick when they drink from muddy puddles? Do dogs have some amazing ability to fight off viruses and bugs?
Beyond the confines of our planet, we’ve also got a question from Olivia, from Sydney, Australia, who regularly contemplates the universe: what is the biggest object in it she wonders? Marnie and her experts do their best to solve these mysteries.

President Trump announced his intention to withdraw from the landmark Paris climate agreement in 2017 and formally notified the United Nations last year. A mandatory yearlong waiting period ended on Wednesday. Of the nearly 200 nations that signed the agreement, the U.S. is the only one to walk away from its promises to reduce greenhouse gas emissions. NPR science reporter Rebecca Hersher shares fives things to know.

Throughout the U.S., the pandemic is still raging. And with cooler weather and the height of flu season ahead, an already dire situation could get much, much worse. On today's show, a pandemic reality check. Short Wave's Maddie Sofia and Emily Kwong talk about how we got here and how we should all be thinking about the holidays and the coming winter.
A NASA spacecraft sent out to collect a sample of rock and dust from an asteroid has nabbed so much that it's created an unexpected problem. NPR science correspondent Nell Greenfieldboyce shares a cautionary tale of a scientific mission that was almost too successful.
