Episode notes

For decades, researchers have been trying to develop a vaccine against r s v. Four companies are currently testing their vaccines in people older than 60. Any vaccine or treatment would drastically reduce hospital and intensive care admissions for the vulnerable groups who can be affected by this virus.

An explanation for giant ice structures on Pluto, and dismantling the mestizo myth in Latin American genetics.

In this episode:

00:46 The frozen root of Pluto’s polygonal patterns

In 2015, NASA’s New Horizons probe sent back some intriguing images of Pluto. Huge polygonal patterns could be seen on the surface of a nitrogen-ice ice filled basin known as Sputnik Planitia. This week, a team put forward a new theory to explain these perplexing patterns.

09:06 How the mixed-race ‘mestizo’ myth has fostered discrimination

The term 'mestizo' emerged during the colonial period in Latin America to describe a blend of ethnicities – especially between Indigenous peoples and the Spanish colonizers. But this label is a social construct not a well-defined scientific category. Now researchers are challenging the mestizo myth, which they say is harmful and has a troubling influence on science.
