A historian reflects on the life of Chinese crop scientist Yuan Longping, and the possible influence of geothermal energy production on earthquake aftershocks.

In this episode:

00:46 Remembering Yuan Longping

Yuan Longping, one of China’s most famous scientists, died in May at the age of 90. Known as the ‘father of hybrid rice’, we reflect on his life and the impact of his research, which helped feed billions of people.

12:14 Geothermal power and earthquake aftershocks

In 2019, a magnitude 7.1 earthquake rippled through California, except – according to some researchers – at the site of a geothermal power plant. Now, a paper in Nature tries to understand why.

Research paper: Im et al.

16:47 Briefing Chat
