Where did the SARS-CoV-2 virus come from? As a team of researchers from the WHO prepares to report on its investigation into the origins of the virus, we discuss the leading theories, including the controversial ‘lab leak' hypothesis.Although there is no evidence to support it, the lab-leak idea remains popular among certain groups. Similar hypotheses were even touted about the Ebola outbreak in Sierra Leone. We discuss why theories like this seem to gain traction.News: ‘Major stones unturned’: COVID origin search must continue after WHO report, say scientistsNews: Where did COVID come from?

A repository with millions of data points will track immunity and variant spread.To answer the big questions in the pandemic, researchers need access to data. But while a wealth has been collected, much of it isn’t collated or accessible to the people who need it.This week sees the launch of Global.health, a database that aims to collate an enormous amount of anonymized information about individual COVID-19 cases.On this week’s Coronapod we discuss how this database could help answer the biggest questions facing scientists right now, from variants to vaccines – could data change the game?News: Massive Google-funded COVID database will track variants and immunityNews: Can COVID vaccines stop transmission?

Researchers in Japan are trying to understand why thunderstorms fire out bursts of powerful radiation.Gamma rays – the highest-energy electromagnetic radiation in the universe – are typically created in extreme outer space environments like supernovae. But back in the 1980s and 1990s, physicists discovered a source of gamma rays much closer to home: thunderstorms here on Earth.Now, researchers in Japan are enlisting an army of citizen scientists to help understand the mysterious process going on inside storm clouds that leads to them creating extreme bursts of radiation.This is an audio version of our feature: Thunderstorms spew out gamma rays — these scientists want to know why Hosted on Acast.

What’s the endgame for the COVID-19 pandemic? Is a world without SARS-CoV-2 possible, or is the virus here to stay?A recent Nature survey suggests that the majority of experts expect the virus to become endemic, circulating in the world’s population for years to come.But what does this mean? On this week’s episode of Coronapod, we ask what a future with an ever-present virus could look like.News Feature: The coronavirus is here to stay — here’s what that means Hosted on Acast.
