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.

The science behind how and when to give vaccines doses.As vaccines are rolled out, massive logistical challenges are leading scientists and policymakers to consider alternative dosing strategies.But what does the science say? In this week’s episode of Coronapod, we discuss mixing and matching vaccines and lengthening the time between doses. Approaches like these could ease logistical concerns, but we ask what's known about their impact on vaccine efficacy – what is the science behind the decisions, and could they actually boost immune responses?News: Could mixing COVID vaccines boost immune response?  Hosted on Acast.
