Episode notes

In 19 61, jan saw this naturally occurring hyber rice. He immediately realized that there must be out there, possibly male sterile plants. And there are male sterile plants. This means that potentially, down the line, you could then develop hybrid rice seed. But rice is a much trick a crop to do this with, because it self fertilizes. So tritofied hybrid versions of a crop which fertilizes itself is very difficult to do. In 19 64, in the height of summer, he and a student did this the hard way. They went into rice fields. You know, the hot sun is beating down on top, while below they're knee deep in water. And

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.

09:55 Research Highlights

The ancient and incredibly well-preserved beetle found in dinosaur poo, and a 5,000 year old, less transmissible strain of plague bacteria.

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.

16:47 Briefing Chat

We discuss some highlights from the Nature Briefing. This time, the new skull fossils that might expand the human family tree, and a new estimate of the age of an ancient ‘living fossil’.
